Central Air Conditioner Troubleshooting; AC Won’t Turn On, Running But Not Cooling House & More

We all rely on on our air conditioners to keep our homes and businesses cool during the hot weather months. Steve’s Heating & Air would like to take this opportunity to address some of the most common central air conditioning problems.

Air Conditioner Won’t Turn On

When you turn on your AC and nothing happens, its easy to panic. The good news is that the lack of power could be something as simple as a tripped circuit breaker or blown fuse. Try resetting the circuit breaker or replacing any blown fuses. When your AC won’t turn on, it could also be the result of thermostat problems as well as loose or broken wiring.

Thermostat Not Working

If you have set your thermostat to a low temperature setting and air conditioner does not start up, it is advisable to call an HVAC repair technician, as we will most likely need to recalibrate or replace your thermostat. Older, dial-type thermostats are more prone to calibration problems, but new programmable thermostats aren’t without their downsides. It helps to consult your thermostat manual to ensure your thermostat is programmed properly.

Low Refrigerant in Central Air Conditioner

One of the most common causes of an ac system not running optimally is low refrigerant. When refrigerant levels are low, it usually means it was either undercharged during installation or it has developed a leak since. Low refrigerant also results in sticky air as heat and humidity cannot efficiently be removed. Unfortunately, it is not always a solution to top off the refrigerant. A recurring leak indicated a larger problem and if multiple leaks are found, it may be time to replace the whole air conditioning unit.

AC Running But Not Cooling House

If you are experiencing warm air or no air at all your your AC supply registers, it could be the result of dirty air filters, low refrigerant, obstructions in your ductwork or a frozen evaporator coil. Changing the air filters is always a great first step but it that doesn’t solve the problem, it is time to call in the professionals!
While embarking on your air conditioning troubleshooting mission, you should consider that your evaporator coil is

Noisy Air Conditioner

A noisy air conditioner making loud humming or buzzing sounds could be because of dirty or worn fan motors. If loud noises are detected, it’s best to shut off your unit and call in an HVAC professional to avoid further damage to your air conditioner.
