Is your AC unit blowing warm air?
The most common causes are typically:
  • An overdamping compressor
  • Capacitor failure
  • Low refrigerant

These can be interrelated issues. For example, a unit running on low refrigerant can put more issues on the compressor. Certified Heating & Air Conditioning has more than 20 years of experience in diagnosing and treating common AC problems.

Common Central Air Conditioning Repair Issues

You have a malfunctioning air condenser. Often times it’s as simple as replacing a fuse or a tripped circuit breaker. But if the power is fine, it’s usually the motor. We can install motors quickly for a reasonable price.

If your air unit is short-cycling (turns on and off repeatedly) there could be dirt or blockage that is affecting the air condenser or evaporator. It’s a good idea to clean your unit every few months. A little bit of dirt and dust can turn into a lot over time.

If your AC system is working but it is not giving you a lot of air, the thermostat might be an issue. But if that’s not the problem, it’s internal. Usually a faulty compressor or lack of coolant can be refilled. Dirt, large blockages such as weeds or even pet hair can cause this problem.
