Common AC Problems and Maintenance Requirements

If your AC unit stops working or is not as efficient as it used to be, it is likely in need of repairs or maintenance. The most common AC repairs needed include:

Refrigerant Leaks - –Refrigerant is not only a dangerous chemical for the environment, it’s also dangerous for humans to be around. Call for repairs immediately after noticing a refrigerant leak. If there are any symptoms of headache, dizziness, vomiting, coughing, or chemical burns, see a doctor immediately.
Clogged Drain Lines –Clogged drain lines are common, especially in older pipes. Generally, they will be caused by algae building up where the evaporator coil creates condensate. The best way to prevent clogged drain lines are with an HVAC maintenance plan, and the best way to remove them are with our professional New York AC repairs.
Broken Compressor –Eventually an AC compressor can get damaged due to mechanical issues or a lack of lubricant. Common signs an AC has a broken compressor are no cool are coming from the vents, “hard” starts, unusual noises, circuit breaker short outs, etc.
Clogged Filter –The AC filter keeps pollutants from outside air from entering your house. Over time though, this filter builds up so much debris that it actually makes the air in your home dirtier if it’s not cleaned. Air filter cleaning is a staple of any good HVAC contractors maintenance or repair routine.

Malfunctioning Breakers or Fuses & Many people feel like they can DIY some of the repairs of some mechanical issues, but we highly recommend hiring a professional for anything electric.
Burnt Out Capacitor –An AC capacitor basically just jump starts the electric charge the unit needs to run. It’s still an electronic device though, so when it’s broken we recommend hiring a professional.
Corroded Evaporator Coils –Over time evaporator coils can get corroded. Luckily, fixing this often is as simple as a condenser coil cleaning. Our New York AC contractors can perform this routine cleaning or offer condenser coil replacements as needed.
Dirty Condensor Coils –If condenser coils are just dirty, there shouldn’t be any need for replacement. However, they will still need to be cleaned and inspected to ensure they’re working properly.
Worn Contactor –The capacitor starts the flow of electricity to your unit, but the contactor controls it. A contactor can either get stuck in the down position, allowing electricity to constantly power the ac unit, get stuck in the up position, blocking power to the AC unit when it’s scheduled to run, or burn out, cutting off the supply of electricity to the unit.
