Mistakes to Avoid When Installing an AC Unit


Do you have plans to install a new air conditioning unit? You have come to the right place. Although the process of operating an air conditioning system can appear to be very simple, many different components have to work together properly.

Therefore, a mistake in the air conditioning installation can seriously affect its efficiency. The following are some of the most common errors that commonly occur in the installation of air conditioning units.

Wrong Size

The most common mistake when installing an air conditioner is choosing the wrong size unit, which is the prevalent case in most parts of Utah.  The unit can either be too large or too small. If it is not of the right size, then it may fail to cool the space as desired and if it is too big, then it might increase operational cost, cause uncomfortable temperature changes, and prevent dehumidification. Dehumidification is a major factor to consider for air conditioner installation in Salt Lake City, as humidity can get as high as 70% in the city.

Therefore, it is vital to contact a reputable air conditioning contractor before you proceed with the installation. The contractor sends technicians to your property to measure windows, ceiling, floors, and walls. They will verify that your home is well insulated and take into consideration other factors before providing you with an estimate of your cooling load.

Wrong Position

Air conditioners need to be installed in the right position to be as energy-efficient as possible. Make sure to position your air conditioner in a shady area, so that it does not have to work as hard to cool your home. When installing window AC, keep in mind that it should be angled slightly towards the rear, allowing proper drainage. The installation of an air conditioning system in a shady area is a good idea, but make sure the vents are not blocked by trees or shrubs. Proper ventilation is necessary for the successful operation of your air conditioner and will ensure a minimum energy bill.

Additionally, make sure you do not place the thermostat near heat-generating light fixtures or other appliances. If the thermostat is frequently exposed to heat, your energy expenditures would increase as your air conditioner would be forced to work for longer hours. The excessive use of air conditioners will lead to the creation of unhealthy humidity levels, and an increase in maintenance costs. In addition, frequent use reduces the lifespan of the air conditioner.

Poor Insulation

Insulating the room properly is crucial. In the case of a window AC, it is recommended that the gap between the bottom and top window panes is filled with insulating foam. Window air conditioning units can also be fitted with insulation panels for better insulation.

To install split-ACs properly, the ducts need to be the correct size. The cooling duct size is calculated based on the load circulation of the system and any error can lead to incorrect efficiency of the cooling system and an immediate equipment failure. Poorly sealed air ducts are another potential source of problems because the cooled air leaks out, increasing the burden on the air conditioner.

Poor Air Quality

Air pollution is a major problem, which often reduces the efficiency of your air conditioning system. Indoor air pollution can be caused by several things, such as carpets, mold, pollen, resins, and mildew. In case of insufficient air circulation and high humidity, the pollution in the indoor air can become worse.

These pollutants can negatively affect an air conditioner’s performance. However, if you work with a qualified technician your problem can be easily fixed as they will advise you on the steps you need to take to reduce the amount of pollution inside your home. Additionally, a contractor can provide you with advice on other equipment that could help reduce air contamination.

Not Checking Leaks

When installing air conditioning, it is important to check the coolant or Freon levels. Leaks can cause many health problems, and even a ten percent loss of Freon can result in an increase of twenty percent in electricity bills. Air conditioning installers typically do not check for leakage because they believe it’s a new air-conditioning system, but a damaged system during storage, delivery, or installation can cause leakage.

Lengthy Refrigerant Pipes

Another mistake that AC installers often make is keeping the refrigerant piping too long. The pipes which connect the central air conditioner to its outdoor and indoor units must not be too long, as this may hinder the AC from completing its cooling cycle. This will also result in the compressor working continuously, resulting in unnecessary energy loss.

Choosing The Wrong Contractor

Many people do not know how to properly install air conditioners. As a result, they hire professionals that can do the job for them. However, when choosing a professional contractor, they tend to choose a contractor with the lowest rates instead of higher efficiency.

Having a poor skill level for aircon installation will result in an incorrect installation and will also result in damage to the aircon equipment. You should choose your installer after making a proper inquiry and not just go with the cheapest service provider.

Having been made aware of some of the most common mistakes made during air conditioner installation, you must try to avoid these mistakes. If you do not, you will end up losing money in the form of increased energy bills. You’ll also get inadequate air conditioning and a shorter lifespan for your system.
