Few home appliance breakdowns are more inconvenient than an air conditioner that breaks down in the middle of a heat wave. Fortunately, there are a few early warning signs you can look out for so you can get your AC repaired before it breaks down. Here are three signs it may be time to repair or replace your air conditioner.
Low Air Flow
Even if the air from your vents is still cold, there may be a problem with your air conditioner if the air flow is lower than it used to be. Low air flow can result from a number of different causes. One of the most common is an obstruction or leak in the duct work. You may want to consider a professional duct inspection and cleaning to remove any blockages and patch any holes that are wasting energy by allowing cooled air to escape.
If air flow from your air conditioner is still low after a duct inspection, the next most likely cause is a problem with the blower motor. The blower motor is located in the indoor air handler and delivers cooled air from your air conditioner to the rest of your home. A worn or loose blower motor belt may be reducing the performance of the blower motor, or the motor may need to be replaced.
No air conditioner is truly silent, but excessive and unusual noise from your air conditioner is never a good sign. Different problems within the air conditioner will cause different sounds, giving you a clue as to what the problem may be.
If you hear a whining sound from your air conditioner, a worn or slipped belt is likely to blame. Loud, grating noises may indicate that the bearings are worn or that the blower motor needs to be lubricated. While a technician will need to perform the repairs, you should take note of the sounds you hear so you can inform the technician and give him a good starting point for repairs.
A Burning Smell While the AC Is Running
If you ever notice a foul, burning smell while you are using your air conditioner, you should turn it off immediately and stop using it until you have it inspected. This problem usually occurs when the insulation on the wiring inside the unit has burned off. Uninsulated wiring in your air conditioner is a fire hazard that requires repair as soon as possible.
Keep these signs of air conditioner problems in mind so you can get early repairs and avoid hot days with no air conditioning. For more information, talk to a professional like Comfort Solutions Heating & Cooling Inc.
