Repair Your Air Conditioner with These Tips
Noise is Loud or Unusual
When a cooling system begins to make unusually loud noises, this is a sign of a problem that should be remedied right away. In some cases, a DIY fix is sufficient, and in others, you need to bring in an HVAC specialist. First, determine if the noise is coming from the indoor or outdoor unit. Then, go to the appropriate unit and look for any obvious signs of wear or a broken part. If you can narrow down the noise to a particular spot; turn the system off and see if there is any minor adjustment or realignment that can be made.
If you hear a metallic rattling sound, you should check all of the fittings and screws for looseness. Tighten anything you find that is loose. It is possible that you might even need to replace a screw or two that became so loose that it fell off the AC unit.
No Cold Air
So, you turned the AC system on, but the unit is blowing hot air instead of cold. Before you get upset, take a walk outside and check to see if the condensing unit coils are blocked by anything. If they are, turn the unit off and remove the debris or hose the coils off.
If the system is still blowing only warm or hot air, or is iced up; you should call an HVAC technician to fix it for you. Most likely, it’s an electrical problem or your unit needs coolant. It might have a leak that needs fixing. Don’t forget to check the breaker or fuse in the electrical disconnect for the outdoor unit.
