When summer produces its hottest days, your air conditioning system should be keeping your living and work spaces cool and comfortable. There are times, however, that an AC unit may not work properly. Here are some common problems that can occur and simple fixes to address them:
Your Air Conditioning Doesn't Turn On
If your system doesn't turn on, your thermostat may be set incorrectly. Check that your thermostat is set to "Cool" or "AC", making sure the temperature is set correctly and that your thermostat's battery is good. You should also check your circuit breaker to be sure the switch isn't tripped.
Your Air Conditioner Cycles On and Off a Lot
If your air conditioner cycles on and off several times an hour, there may be dirt or debris in the condenser or evaporator. If you don’t feel comfortable cleaning the unit yourself, you can bring in an HVAC professional to do the job.
The Air from Your AC Doesn't Feel as Cool as it Used to
If you notice that your air conditioner isn't cooling as well as it did in the past, there may be a restriction in the airflow. Usually, you can correct this by changing or cleaning the filter. Another culprit may be plants or debris blocking the airflow from the condenser. If you remove objects from around the condenser, you may get better airflow from your unit.
Water Puddling or Leaking from Your Main AC Unit
If you see water puddling or leaking around your main AC unit, this could mean there's a clog in the line leading out of your AC unit or a line connection is loose. Inspect any outgoing lines you can easily see and call your AC professional if you can't clear the problem on your own.
