I am the Install manager at Fire & Ice, since 2017. I take spent 28 years in this business concern and take experienced almost every aspect of HVAC from Industrial, commercial, and residential buildings. From design, install, service, or sales, if it moves air, I've worked on information technology.

About This Article

An in-depth air conditioner installation process guide. Learn how installation procedures dramatically affect the lifespan and effectiveness of your air conditioner.

I'm non going to prevarication, the installation process for a new air conditioner is complicated. When customers ask me what's involved in the process, they're oftentimes shocked to learn how much goes into it.

The more worrying fact is that at that place are many HVAC companies and air conditioner installers who don't know all the steps that should be office of a good installation. It'southward easy to cut corners and then that an A/C organization runs "expert enough." But "expert enough" ofttimes means losing thousands of dollars in energy costs over the life of your system, and decreased comfort for you and your family. This is unacceptable.

Practice you want a sleek, efficient car powering your ac, or a comfort-robbing trashcan outside your home? I'm guessing yous'd prefer the old. Well, you're in luck.

In this article, nosotros are going to comprehend the entire air conditioner installation process in detail, from outset to finish! If you're committed to getting the virtually from your air conditioning system, read on. By the end, you'll accept the peace of mind that comes with understanding each step. It will as well let you to pick a company whose installation procedure is up to snuff.

Importantly, this is not a DIY guide. Air conditioning installation should always exist handled by a licensed professional. Once you read each step involved, it should be like shooting fish in a barrel to see why.

Planning the Replacement or New Installation of Your Central Air Conditioner

The earth has changed then much in simply the by few years. So imagine how much has changed in 10 years. Or xx. Or 30.

Virtually existing air conditioners that are replaced today are between the ages of eight to 30 years old.

Modern air conditioners are twenty-50% larger in height, length, and width. This allows for a larger gyre which, in plow, makes the air conditioner more efficient. Considering of the larger size of mod air conditioners, the current location of your existing air conditioner may not adjust the new one. Sometimes the air conditioner must be relocated, particularly if in that location are state or manufacturer regulations on infinite clearances surrounding your unit. Others require that unit of measurement to be within a sure distance to the utility meter. In some cases, this creates boosted costs.

This is the offset consideration for a homeowner, because information technology may require moving equipment or modifying your home'due south ductwork.

So what's the good news? Modern air conditioners are significantly quieter and more efficient than their predecessors, then your costs are often offset by these benefits.

Collecting A/C Information During the Home Estimate

During your initial in-home visit, the estimator has the responsibility of reviewing the existing air conditioning system. Of import information needs to be collected and then they can provide yous an accurate proposal. This information is then passed to the installation team.

Depending on the job, specialized equipment may be needed, which the installation team can bring with them because of this step.

Having the proper data earlier the 24-hour interval of installation increases the chances of the chore existence completed successfully and promptly.

The Inflow of the Install Team, Review, and Condom

Before your installation team arrives, you should receive a phone call or text letting you know they're on their manner.

Many skilful HVAC Companies will also send pictures accompanied by bios of the installation squad that will be working at your home ahead of fourth dimension. This is an boosted safety and comfort factor before a stranger enters your domicile.

One time they arrive, the lead installer will share and review the job data with you. This is oft included in a package that includes details of the job. This packet contains the equipment data, accessories to be installed, and any special instructions given by yous to the estimator before the sale.

Information technology'southward important to allow a few moments for this review. This volition prevent plush and aggravating mistakes from happening during the installation. Communication is a key component to a successful installation.

While you are reviewing the job details with the lead installer, the other fellow member(s) on the team will use this time to start laying downward floor protection and getting tools and equipment in place. They will also offset a safety process that includes turning off electrical circuits and gas supply to the existing HVAC equipment.

Removing Your Existing Central Air Conditioner

Your existing air conditioner contains a refrigerant that needs to be removed before a new one tin can be installed. According to the EPA standards, information technology is unlawful to openly vent this refrigerant into the atmosphere.

A device known every bit a recovery automobile must be used along with a recovery tank to safely and legally remove the refrigerant in the existing central air conditioner organisation. This is the only process that allows for the safe removal and proper handling of the refrigerant.

Whatsoever individual handling any refrigerant or equipment containing refrigerant must accept an private EPA certification. An EPA certification just certifies the name listed on the certification. Therefore, each member of the installation team, service team, or anyone who might handle refrigerant or equipment containing refrigerant are required past law to accept their own individual EPA certification.

One time the refrigerant is recovered properly, electrical wiring is asunder from the existing air conditioner. Near the air conditioner is a disconnect box, which is a safety device in case of emergencies. Information technology can shut down your A/C unit.

From the disconnect box, a "whip" (flexible electrical conduit) carries the ability to the air conditioner. Skilful HVAC companies replace the disconnect and the whip when replacing an air conditioner, to ensure system prophylactic.

In cases where an one-time system lacks a disconnect box, a new one is required by safety codes to be installed with the new air conditioner. There are specific installation guidelines for sizing and wiring the disconnect properly.

The circuit breaker should exist turned off in the electrical console before any work is to exist done inside the service disconnect. One time all the existing connections are safely removed, the existing air conditioner is fix to be removed.

Preparing the Area for the New Central Air Conditioner

In virtually cases, the existing location of the air conditioner will require some prep work before the new air conditioner can exist fix in place. This prep work includes replacing the pad that the new air conditioner volition assault.

New air conditioners are larger and taller than their predecessors. There are also times when the ground has sunk. Earlier the new pad can be set, the ground must be leveled. Good HVAC companies employ a gravel base to level out or build up the area where the new air conditioner volition be placed.

Some people think information technology is better to have a concrete pad poured for the new air conditioner to fix on. A physical pad is not necessary and can crack and shift drastically. When this happens, it is very difficult to repair or remedy. Instead, a composite pad is recommended. The blended pad is purposely designed to exist outside and last the lifetime of the new air conditioner. Additionally, information technology's often better equipped than concrete to blot vibrations from the automobile, which tin reduce dissonance and shaking.

Once the new air conditioner is installed, it cannot be moved or lifted safely without damage in most cases. Many internal elements are rigid and pressurized. Moving it after it is connected could permanently damage the system. A composite pad tin can avert damage to the air conditioner if it needs to be leveled in the hereafter.

Removing the Existing Indoor Evaporator Gyre

The indoor evaporator coil is the other half of your air-conditioning system that sits above the furnace, though in some cases it will sit below the furnace. This is what the other end of the refrigerant lines are connected to.

The indoor evaporator gyre has 2 variations. Ane is cased and the other is uncased. In either application, the sheet metal plenum must be asunder before the new curl tin be installed. This process can exist complicated when access to the ringlet is restricted.

The almost common restrictions are rooms congenital around the arrangement such every bit closets or finished basements. This prevents access to all sides of the curlicue or plenum. An additional charge may be added to the cost of the chore based on difficulty. Because nigh indoor coils are more efficient, they are taller. Boosted prep piece of work to the supply plenum may be required before the new coil tin can be installed.

Removing the Existing Copper Refrigerant Lines (Line Prepare)

Side by side, the existing refrigerant line set can be removed. This is a set of 2 copper lines through which the refrigerant travels from the outdoor condenser, then dorsum into the indoor evaporator coil.

The refrigerant line prepare is unremarkably strapped to the bottom of the flooring joists. These straps are removed, and the line fix is taken downwardly. It's recommended that the line prepare exist replaced in every case that it is exposed and accessible.

Refrigerant travels through the lines along with oil. In older air-conditioning systems, the oil in the existing line prepare is different from the oil found in the new air conditioner. These oils cannot be mixed without dissentious the new air workout system.

Sometimes the line set is curtained past a ceiling or in a wall, or information technology is buried undercover or in concrete. Sometimes providing admission is not an option or possible. In these cases, you have the option of finding a new location to run a new line set or reusing the existing line set remains. If the existing line prepare must be reused, it must be flushed and cleaned properly, so force per unit area tested. It is never recommended to keep an existing line set if it can be replaced.

Installation of the New Indoor Evaporator Coil

There are two options when installing a new evaporator coil for any new air conditioner arrangement: cased and uncased. The preferred pick is a cased coil, because it comes in an insulated cabinet with removable panels on the front that allow access to the coil inside.

The cased coil is also designed to sit on top of the furnace without any modifications, which makes repairs and modifications piece of cake. In nigh cases, information technology will exist painted to match the color of the furnace. The biggest benefit of using a cased curlicue is that it comes pre-cased by the manufacturer. This makes failure from an improper installation highly unlikely, regardless of the skill level of the installer.

When using a cased curlicue, it is already "installed" past the manufacturer and merely needs to be placed on the tiptop of the furnace. The final stride at that point is to connect and seal it to the existing sheet metal plenum.

An uncased gyre is the coil without an insulated cabinet. They have more installation requirements and longer preparation time. They are bachelor in the same variations as the cased coil.

Uncased coils are typically more than hard to install. However, an uncased coil will provide the aforementioned condolement and be just every bit efficient equally a cased scroll when installed properly.

Before the coil can be congenital into the existing canvas metallic supply plenum, there is specific preparation required. These requirements are specified by the manufacturer. Failure to follow the installation transmission's guidelines may issue in harm to the furnace as well as the coil.

The bleed pan on the whorl is plastic, so rails need to be fabricated by the installer to make certain the curl is sitting the proper distance in a higher place the furnace heat exchanger. This keeps the bleed pan from melting. If the bleed pan melts into the furnace, it could permanently damage the furnace or cause a fire.

One time the rail are built and installed, the coil can be installed into the supply plenum. If the plenum is larger than the ringlet, a sheet metal pan must be built with an opening provided below the curl. This opening needs to mirror the bottom opening of the coil for proper airflow from the furnace going through the scroll.

If the opening is not big enough, or as well much air goes effectually the coil instead of through it, the curl will freeze into a block of ice. This can damage the coil and cause a refrigerant leak past slap-up the tubing carrying the refrigerant.

Once those are installed, the final step is building the front of the plenum. It is possible to build an access panel door into the plenum to cover the coil. This is not required by any code or manufacture specification, so it would be upwardly to the installer. In all scenarios, the cover must have holes provided for the refrigerant lines, and then likewise for the condensation lines to be connected.

The blazon of whorl chosen is mostly based on the details of the installation. Some won't allow for a cased coil due to sizing restrictions, for example. Regardless, if the curlicue is installed per code and manufacture specifications to the existing duct system, can drain properly, and is sealed from air leaks, you will enjoy the same level of comfort. At that place is no difference in warranty or life expectancy betwixt either type of coil.

Installation of the New Copper Refrigerant Lines (Line Ready)

The new refrigerant line set is a combination of 2 individual copper lines. One line is always bigger than the other and is insulated. The bigger line is called the suction line, and the little one is called the liquid line. They come packaged together, rolled in a coil. It is available in multiple selections of lengths, from xv-50 anxiety. You will rarely need more than fifty anxiety in a residential home.

The primal is installing the line with as few bends and turns as possible. When these bends are necessary, the soft copper tin can be aptitude past mitt or a tubing bough.

It's common to install the line set up as close to your home'due south beams and ductwork as possible. It'southward as well recommended that you secure the line every four-6 feet. Plastic or copper strapping is common. Metallic straps or clamps tin can exist used, simply it'due south of import to protect the copper wiring if the clamps affect them.

If you don't properly protect the line, it can corrode. Galvanic corrosion (also chosen bimetallic corrosion) is the breakup of metallic when two dissimilar metals come into contact. This does take some time to occur. Nevertheless, if allowed to occur, it could eventually reduce the integrity of the copper refrigerant line over time until it causes a leak.

Afterward the hangers are installed, the line set can at present exist put in identify. Typically, an installer will kickoff with the suction line and roll out one end a few feet, leaving the rest of the curl in a whorl. They then push the unrolled section through a hole drilled through the band board of the house to the outside, most the air conditioner. Enough of the line is pushed out to reach the service valve of the air conditioner.

Eventually, the installer will connect this line to the air conditioner itself. The hole size volition exist between 2-2.5" in diameter, depending on the blazon of line set being used.

After the line is outside past the air conditioner, the line is secured by hangers most the pigsty and then another hanger back a couple of feet. The line is then carefully uncoiled and formed along the floor joists upwards against the trunk line ductwork or a beam, as straight every bit possible until long radius turns or bends are needed. Forth the fashion, it gets put into the hangers that take been installed previously, securing information technology in place.

The line set up volition run from the air conditioner outside to the new indoor evaporator roll on top of the furnace. Subsequently the suction line has been installed and secured, the smaller, liquid line is run along the suction line, secured in the same hangers.

A line prepare should be new, installed as one piece, gratuitous from any sharp bends or kinks, and secured with an advisable hanging system.

There volition also be a small, depression-voltage control wire that runs from the furnace along the line set to the air conditioner outside. The small existing wire coming from the thermostat to the furnace sends a low voltage signal to the air conditioner to turn on and off when a phone call for cooling is needed or has been satisfied.

Setting the New Air Conditioner Condenser

So far, we've fix the pad, leveled it, and our refrigeration lines and electric disconnect are ready to exist wired into the new air conditioner condenser.

Removing the new air conditioner and setting it on the pad is step one. Afterward uncrating the unit, a good installer will inspect for whatever damage. Sometimes panels or coils volition get damaged in transit. Whatsoever damage should be reported to y'all immediately.

Fire & Ice Heating and Air Workout runs multiple inspections on equipment, both when it arrives and when it's installed, to ensure it is in working guild.

If there is a dent, that doesn't necessarily mean in that location is any damage that will affect performance. Yet, y'all always have the right equally a client to not accept the damaged unit of measurement and ask for another 1.

The line gear up that was installed in the previous step is and so formed and fitted to the appropriate service valve on the new air conditioner. The service valve is a connection point for the line set, and also isolates the refrigerant independent inside the unit of measurement. Service valves also permit for the outdoor condenser portion of the air conditioner to be isolated from the indoor curlicue and line set up for time to come service or repair needs when needed.

Isolating the refrigerant keeps you from having to replace it with all new refrigerant in case of a repair in the future.

After the line set up is fitted to the service valves, they must be brazed in. Brazing, a form of welding, is a procedure using ii gases (oxygen and acetylene) and a filler rod made of an alloy metal and silver to join the copper line set and service valves. The valves are heated to a minimum of 1200 degrees Fahrenheit or until the filler rod will flow to weld the connectedness.

If this process is completed properly, the copper line set, the filler rod, and the service valve are all melted together for a tight, leak-free connection.

Filter Dryer Installation

Filter driers are a primal component in the refrigerant system. They serve ii main functions. The most important role of a filter drier is to absorb moisture. The second is to provide physical filtration.

When installing a new air conditioner condenser, you must ever install a liquid line filter drier into the refrigeration arrangement. Almost new air conditioner condensers come with a liquid line filter drier for you lot to install.

Manufacturers recommend the filter drier be installed close to the expansion valve (TXV) at the indoor coil, as often as possible. This keeps the TXV protected and keeps the filter drier from existence exposed to atmospheric condition where it could rust.

There is too an pointer for period management. This arrow must e'er be in the direction that is going into the indoor coil.

Any contaminants in the refrigeration organisation are harmful. Water or wet is the worst.

Moisture enters the arrangement in unlike ways. If a organization is not evacuated properly, moisture will exist in it. Moisture can also come up from leaks or motor windings. The h2o tin cause corrosion and create failure in metal parts.

H2o or moisture tin besides react with the oil in the refrigerant organization. This is called hydrolysis, which forms acids in the organization. Acids, moisture, or whatsoever other contamination in the lines volition be extremely dangerous to the integrity of your new air-conditioning organization.

All good HVAC companies have strict processes in identify for their install teams to foreclose failure as much equally possible. Whatsoever time a refrigerant line is open to the atmosphere, information technology is vital to install a new filter drier. This is true of installations as well as service repairs.

This brazing procedure is the same for connectedness to the indoor evaporator curl. This, once more, involves open flames and should but be performed past a trained professional.

The gases used in the process are explosive. In that location is an open up flame outside and inside the home. It can be dangerous to the installer, the homeowner, and the home, causing permanent damage without proper training. Following manufacturer and safe guidelines is central.

Preparing the line fix for refrigerant in this style is the most important pace in ensuring the rubber and efficiency of your air conditioner.

Sadly, this process is unknown or non followed to about install teams. Not all companies are equal in training or processes, and many contractors lack the proper equipment. A good HVAC company will accept all the tools and processes needed to install the air conditioner professionally and thoroughly.

After the line set is fitted properly into the service valves and indoor coil, heat protection needs to exist practical. Estrus protection can be a heat-absorbing paste, wet towels, or rags. Annihilation that would go on the heat spreading into either of the coils is acceptable. The service valves on the outdoor condenser comprise rubber O-rings that will cook if they aren't protected. If the valves are overheated and the O-rings are damaged, the refrigerant will leak past the valve into the line set, losing the factory charge.

From the manufacturing plant, the air conditioner condenser is prepared, cleaned, and the refrigerant is added. If the refrigerant is exposed before the process is completed, it becomes contaminated, along with the condenser coil. If this step is performed improperly, all the refrigerant would need to be recovered and the condenser coil would need cleaned and prepared over again before whatever refrigerant could be added.

Most indoor coils have a metering device called an expansion valve that will be damaged if non protected from the heat during brazing. If these become too hot, or whatsoever contaminants are introduced, the expansion valve will exist compromised and fail to operate.

Once the heat protection is completed, a tank containing a gas called dry out nitrogen is hooked upwardly to a regulator and perhaps a manifold estimate fix. This allows the nitrogen to be purged while brazing. The nitrogen protects the inside of the copper tubing from oxidizing during brazing. The damage will not always be nowadays immediately.

The HVAC industry requires brazing with nitrogen every time to prevent this damage.

Brazing with nitrogen, when done properly, will give the organization maximum opportunity for performance, reliability, and dependability. After the system is brazed in both the indoor and the outdoor components, it must exist checked for leaks using the same dry nitrogen, upwardly to a specific amount of pressure. Using the dry nitrogen to pressure level exam the arrangement achieves three things:

1. It'southward a preliminary leak test.
2. The dry nitrogen will pick up moisture.
3. It will as well purge some contaminants out of the system upon its release.

Information technology is very of import to verify with the installation manual provided by the manufacturer what they recommend for force per unit area. Most systems are designed for 150 PSI when testing.

If there is besides much pressure added, problems can occur. If the pressure level is also loftier for the O-ring seal, for case, the nitrogen volition drain into the refrigerant, contaminating information technology.

In this scenario, all the refrigerant contained in the condenser from the factory will exist compromised and will have to be recovered, then the coil cleaned and prepped for more refrigerant.

If the preliminary leak test with nitrogen holds for a minimum of 10 minutes, then it's time to motion on to the next crucial pace: vacuuming the organisation.

Typically a system is vacuumed to a minimum of 500 microns. The manufacturer'southward recommended vacuum is found in the installation manual. Refrigeration systems are designed to operate with only oil and refrigerant flowing through them.

Our atmosphere is fabricated up of oxygen, nitrogen, and wet. These are enemies to the system's functioning and may enter the arrangement during installation or servicing. Removal of these, along with air or other non-condensable products, is required. This is achieved through the vacuum procedure when installing the air conditioner. The vacuum process tin have no less than xxx minutes and upwardly to an hour or more depending on the size of equipment coils and length of line set.

Failure to provide a dry, moisture-complimentary atmosphere before introducing the refrigerant into the rest of the arrangement volition in all cases promote an inconsistent operation, and eventually permanent failure of the organisation.

To achieve a successful vacuum on an ac system there are several key tools and equipment that must be used:

1. A reliable vacuum pump
2. A micron gauge
3. Manifold and hoses
4. Vacuum rated cadre removal tool

The vacuum must achieve 500 microns or less in the organisation and concord the vacuum for this to be successful. This is also the second and final leak test. If a organization does not hold a vacuum, then there is a leak somewhere.

Once a proper vacuum is achieved and has proven to hold, the arrangement is ready to take refrigerant introduced to information technology. Refrigerant is the but production that can "break" the vacuum. If hoses are disconnected from the organization before the refrigerant has been released into the system, the atmosphere will interruption the vacuum. If this happens, the vacuum process must be redone earlier refrigerant tin can be introduced.

With the hoses yet continued to the service valves of the air conditioner, the refrigerant is released into the arrangement, breaking the vacuum by opening the suction-side service valve commencement followed by the liquid side 2d.

Installation of the New High- and Low-Voltage Wiring

For the air-conditioning system to operate, the high- and low-voltage wiring must be reconnected. Using the existing ability supply from the electrical console inside the dwelling house, the installer will mount a new service disconnect box. The disconnect is mounted securely to the side of the house using appropriate fasteners, based on the type of surface it is being mounted to.

In that location are 2 main types of disconnect boxes. One is fused and the other is non-fused. They are both appropriate to utilise outdoors. A fused disconnect allows the proper overcurrent protection required past the manufacturer. This blazon is most common and required when the chief excursion from the panel exceeds the maximum required overcurrent protection. It too allows for boosted safety to the air conditioner condenser.

A not-fused disconnect may be used only in cases where the breaker matches identically to the manufactures listed maximum overcurrent protection. At that place is a minimum and a maximum required overcurrent protection. Y'all must be within these guidelines. The system will non pass the lawmaking requirements if they are not.

For example, if y'all take an existing xl-amp circuit that supplies the disconnect, merely the listed overcurrent protection is only 30 amps, you must use the fused disconnect and install 30-amp fuses with it to properly protect the air conditioning condenser. If the amperage from the breaker matches the maximum or the minimum overcurrent protection, a non-fused disconnect is acceptable.

The service disconnect has specific locations for the high voltage excursion from the panel to be connected and specific locations for the power to go to the air conditioner itself through the electrical whip. They are identified equally "Line" (wiring from the electric panel) and "Load" (the whip that takes power to the air conditioner). This allows the pull inside the service disconnect to break or disconnect the power supply to the air conditioner without having to shut the breaker off from the primary panel.

Considering the air conditioner is exterior, it would be cumbersome to run in and out of the house to plow the power on or off in instance of emergency or servicing. The service disconnect is required by state and local code requirements.

There are as well requirements for placement of the air conditioning condenser. It boils down to making sure there is proper accessibility. All the electrical connections should be made according to the NEC (National Electrical Lawmaking). The depression-voltage command wire is continued directly into the air conditioning condenser at the proper locations according to the air-conditioning condenser installation instructions.

This is the "signal" from the control lath in the furnace sent through the wire to the air conditioner when the thermostat calls for cooling. The low-voltage control wire is what allows the air conditioner to wheel according to the parameters fix regarding temperature and humidity inside the home. The depression voltage wiring is connected to the control board inside the furnace on designated terminals.

Installation of the Condensate Drain Line

The wet removed from the home during the cooling process travels downward a plastic PVC piping. It must be connected to the primary side of the evaporator curlicue. The evaporator coil has a primary and a secondary bleed location. The primary condensate drain line volition travel from the indoor evaporator coil to an appropriate floor bleed or condensation pump.

A condensation pump is used where a proper floor drain does not exist in the home. At that place are too other reasons where a condensate pump is required or is beneficial to install. The important affair to think if a condensate pump is used is that it must be serviced a minimum of twice a year to maintain proper performance.

Any condensate tubing or pipage should exist secured and glued with the proper cement. A trap and an overflow prophylactic switch must also be installed in the condensate system. This is to protect the equipment and the area from flooding due to a restriction. The safety overflow switch is connected to the secondary port on the indoor evaporator coil and wired into the furnace control to close down the organisation when it is tripped.

Startup Commissioning Process

The startup and commissioning (testing) process is done after the system is completely installed and ready to operate. The system is turned on and must run for 15-20 minutes. This will allow the refrigerant to catamenia through the organization and get-go the air-conditioning process.

Upon initial startup of the new air workout system, the business firm should be very warm or accept a "load" with a warm enough temperature inside the home to allow for the minimum potential to charge the system accurately. A temperature above 75 degrees Fahrenheit is recommended in nigh cases. This allows the components in the air workout system to be in total performance to allow maximum cooling potential during charging.

Sometimes running the furnace to oestrus the house is a common exercise to provide the necessary load on the home. Later on 15-xx minutes of operation, the system can at present be commissioned.

A skillful installer volition check the thermostat operation, system sequence of operation, and multiple other areas. While the system is operating, the following data is important to collect to ensure proper performance within manufacturers' specifications:

1. Suction and liquid line pressure
2. Suction and liquid line temperature
3. Superheat
4. Subcooling
5. Outdoor ambience dry bulb temperature
6. Indoor ambient dry seedling temperature
7. Indoor moisture seedling temperature
8. Return air temperature
9. Supply air temperature
10. Static pressure from render side, supply-side, and total static readings
11. Temperature drop calculated
12. High voltage current reading
13. Amperage on the blower motor, outdoor fan motor, and compressor
14. Low voltage current reading
15. Line set length
16. Amount of refrigerant, if whatever, added to the system
17. Distance higher up or below the outdoor unit is in relation to the indoor coil
18. Blower speed tap/CFM recorded

This is the bones listing of the proper information that should exist known and recorded. This is the merely fashion to know for sure how the arrangement is operating and if information technology is within manufacturing specifications. If whatsoever of these practice not fall within manufacturer specifications, your system may non be warrantied by the manufacturer.

Commissioning is important for several reasons. For yous, the peace of mind that you are receiving a properly gear up upward and adjusted arrangement for maximum comfort, efficiency, and dependability. Information technology also ensures the manufacturer's warranty will be in full effect. The benefit to the company installing the organization is that it gives a baseline of operational operation in case any problems arise later.

It also gives the installing squad confidence that before they leave, your system is in perfect operation. It is very mutual for systems to exist installed and started upwardly without much consideration for proper commissioning.

Unfortunately, many companies plow it on and walk abroad the moment common cold air is coming through the vents.

Proper commissioning is a specific process that requires preparation and special equipment to perform the procedure correctly. Information technology also requires boosted time and labor on a job site. Commissioning is the only way to know for sure exactly how well your system is operating.

Why would a company skip this step, and then? In a discussion: price. Skipping this process costs a company less, which in turn might lower your initial investment slightly. This is a long-term gamble, though, with your money, your safety, and your comfort.

A good HVAC contractor will have trained installation teams that will properly committee your air conditioner before they leave the job.

Make clean upwardly and Closing Procedure

The cleanup process is comparatively simple. All cloth and onetime equipment should be loaded up and taken away from the home. The floor protection should be rolled upward concluding, keeping all debris from the installation inside the drop cloth and out of your domicile.

All areas should be swept and free of whatsoever materials or debris. You should look to see the expanse in the same condition in which information technology was found.

A walkthrough of what was done during the installation should be completed with you. Going over safety, maintenance, warranty, and all special instructions are expected.

As a final mechanical stride, a locking cap should be placed on the outdoor portion of the unit. This cap tin only be unlocked with the correct key. This is to prevent tampering with your equipment, and also to forestall theft of the refrigerant. This cap is oft a specific color, which will let a technician know which type of refrigerant your system uses.

A visual inspection of the work completed should also exist offered. Finally, a review of the commissioning and thermostat operation. Afterward the final walkthrough, concluding signatures and payments are nerveless.

Installation Completed Professionally

The chore is now complete!

The procedure may seem long and complicated, but in the hands of a skilled installation team, the entire procedure should exist second nature.

Don't cut corners with installation. Your money and comfort are at risk if any of these steps are skipped. Knowing the full process will allow you to concur companies accountable when you decide to invest in a new air-conditioning organisation. The event volition be a comfortable, efficient, long-lasting product.
