There is nothing more frustrating in the middle of the summer than hearing your AC go on and still not feeling that the temperature is getting any cooler. You might approach your thermostat several times in the hope that this time the temperature will respond to the number you set it at, only to confirm that it won’t. If this is happening to you, it may be time to call an AC repair service to come and see what the problem is. Read on to discover some of the main reasons why your AC may sound like it’s running but fails to cool your home.
Filter May Need To Be Changed
Your AC filter has the job of catching debris, dirt, and many other airborne particles. However, when it gets too clogged, it may affect the way the AC unit works, not allowing air to flow through it and cool the house. If changing the filter does not resolve the problem, it may be time to do some more research.
The Condenser Unit Is Blocked
The exterior of your outdoor condenser unit contains a large coil that wraps around the equipment. Grass, leaves, and other debris may accumulate in the coil, not allowing it to pull air into the unit or to pull the heat energy out of your home. The result is reduced energy efficiency and warm air in the home. In extreme cases, it may lead to a complete equipment failure. You may attempt to clean the visible debris, but the best option is to call in the pros.
The Heat Pump Is Damaged
The heat pump works just like the condenser and tends to have the same issues. It can get dirty, clogged, malfunction, present a refrigerant leak, and more. When this happens, you must call a professional.
The Evaporator Coil Is Frozen
The evaporator coil is an important indoor component of your air conditioning system. Warm indoor air circulates through the evaporator coil so that heat energy and humidity can be removed from the air, resulting in cooler, more comfortable air blowing within the home. The main signs of a frozen evaporator coil include visible frost on the upper refrigerant tubbing, inadequate cooling, excessive condensate drainage near the unit, and an increase in your energy bills.
A Refrigerant Leak
The refrigerant runs through the equipment’s indoor and outdoor coils, drawing heat energy and humidity from indoor air and releasing it outside. A refrigerant leak can result in your AC not blowing cold air or your system running for longer periods without being able to cool your home, and it can cause your compressor to be damaged or fail.
If you have gone through the list above and none of those issues seem to be the problem, you may simply have a unit that is too small for the space you need to cool. You should consider not only the space but also the type and quality of the home’s construction, the type of insulation, local climate, and other factors. To be sure to buy a unit the right size, get a professional to guide you in the right direction.
