Resolve Sensor Issues

Many air conditioners have thermostat sensors which read the temperature in a room to determine if it needs to pump in more cool air. Unfortunately, this sensor can sometimes misread temperatures, causing constant cycles or other strange behavior. The problem could be as simple as a misplaced sensor, or it could have something to do with poor wiring. Whatever the case may be, replacing or fixing a thermostat sensor is fairly simple in comparison to other air conditioner maintenance.

Ensure Working Electronics

Along the same lines as checking for sensor damage, it’s also important to make sure that the fans and wires that keep everything functioning well are in good condition. Dust buildup can keep a fan from working efficiently and can cause a great deal of noise. In addition, wires can become corroded and cause poor connections in your device, which could easily make your air conditioning less effective. If you see any signs of corrosion, seek the help of professional HVAC maintenance service.

Check for Refrigerant Leaks

A refrigerant leak can be bad news. Not only is it possibly bad for the environment, it’s also a sign of a serious problem that will need to be properly repaired. Simply refilling the liquid will not fix the problem, because it is leaking from somewhere and will more than likely keep leaking, even after adding more refrigerant. For these concerns, you should probably contact a reputable HVAC repair company in your area. Once repaired, the device should be recharged with refrigerant.
