As temperatures continue to rise outside, the demand on your AC also rises. To help you handle the Las Vegas heat, you need a properly functioning air conditioner that can keep your home cool and comfortable. With annual AC maintenance, you can be sure that your air conditioner will continue to work effectively and efficiently, but if you notice signs that AC repair might be necessary, be sure to act quickly before an AC repair problem leads to an AC system replacement. The last thing any homeowner wants to deal with on a hot day is the need for an AC repair, but here are 5 AC problems to watch for.
Low Refrigerant Levels
Air conditioners need refrigerant in order to operate efficiently. Refrigerant is a controlled chemical used to cool the air flowing through air conditioning units as it passes through coils.An AC unit should use the same charge of refrigerant for years, but if your air conditioner is not cooling your home as it should be, it may be due to low refrigerant levels or a refrigerant leak. Even the smallest leak can cause problems for the function and efficiency of your air conditioner, so be sure to schedule professional AC repair to inspect your unit for leaks or low levels and have it fixed quickly. Refrigerant is not only harmful for both you and the environment, it is also actively regulated by the EPA and should only be handled by experienced professionals with the appropriate licensing.
Dirty Air Filters
Air filters can quickly become dirty and clogged from dust, dirt, pet dander, and other airborne contaminants preventing air from flowing freely and cleanly through your system. Air filters help to ensure that the air you breathe in is free of contaminants, but they also work to protect the unit itself from collecting dust or dirt that could affect how well it functions. Dust, pet dander, dust, and more can clog air filters, block airflow, and force the unit to work harder than it should be, so make sure that air filters are replaced every three months. By simply replacing old, dirty filters you can improve the energy efficiency of your AC unit by 5-15 percent.
Frozen Evaporator Coils
Evaporator coils are responsible for controlling the temperature of refrigerant. When dirty or clogged air filters have not been replaced, airflow through your unit is prevented causing evaporator coils to overwork and ice up. Frozen evaporator coils can be a clear indication of a troubling problem and should be quickly addressed. If you notice ice build up, excess condensation or moisture, or a full or overflowing condensate pan, you may have a problem with frozen evaporator coils. Frozen coils could also be a sign of a refrigerant leak, so do not hesitate to schedule Las Vegas AC repair.
Dirty Condenser Coils
Dirt, leaves, and grass can build up on outer condenser coils and limit your unit’s ability to absorb or transfer heat. Dirty condenser coils can also obstruct airflow and force your air conditioner to work harder and longer to cool your house, which in turn overworks your system, uses more energy, costs you more money on your utility bills, and can even lead to a premature AC breakdown.
The two blowers on your air conditioner work to blow away the air that collects near the coils. While one blower blows hot air out to keep the unit from overheating, the other blows cool air in to keep your home comfortable. Without properly functioning blowers, the air around the coils of your unit can either overheat or freeze.
