If your air conditioner is not working properly, there are a few things you can do to assess the issues before you call an air conditioner repair service. Most major issues will still need to be handled by a qualified technician, but there are steps that you can take to help determine the cause of your problems. Here are a few:
Check your outlet plug.
If your air conditioner is not working at all, the fix could be simpler than you think. Check to make sure that the cord of your air conditioner unit is firmly plugged into an outlet. If you have children or indoor pets, a cord can easily be inadvertently disconnected.
In addition, a lack of power could be caused by an interruption in the electrical flow to the outlet servicing the air conditioner. Check the breakers of your home to ensure that they have not been tripped by an electrical overload. Also, check the fuses of your breakers. A blown fuse can cause all of the outlets in a breaker zone to become inoperable.
Check your thermostat.
Since your thermostat relays the requested temperature setting to your air conditioning unit, if it malfunctions, your unit will not work properly. Look at the temperature setting. If it is higher or lower than it should be, adjust it to the desired temperature and wait to see if the air conditioner starts to correct the temperature of the room.
Check your vent filters.
Dirty filters can affect the efficiency of your air conditioning unit. The uptake vents in your home suck air out of your living space so that it can be cooled by your unit before being recirculated into your home. Dirty filters can lessen the amount of air that is fed to your system and returned to the rooms of your home, causing your home to cool slowly.
Replacement filters are available at local hardware stores, and they can be changed without much effort. However, pay attention to which side of the filter should be facing the inside of the vent. It is typically designated by arrows on the cardboard sides of the actual filter. The filter dimensions are also usually displayed on the filter frame. If the correct filter size is not used, the filter will not function as it should. Filters that are too large may not fit, and filters that are too small can leave gaps around the vent.
If your air conditioner has stopped operating or is no longer cooling effectively, there could be multiple problems with your system. If you are not able to easily remedy the issues yourself, contact an AC repair company for an in-home assessment.
