You rely on your air conditioner to keep your home cool and comfortable. Given that, the last thing you want is for your air conditioner to break down. Catching a problem early on can save you a lot of time and money down the road. You need air conditioning service if you notice any of these signs of trouble.
Lack of cooling. Is your air conditioner blowing warm air, or is the air simply not as cold as you expect? Your unit’s condenser might be failing. The refrigerant could also be low. In either case, you need the help of an HVAC professional. If some rooms in your home are cool while other rooms aren’t, it can indicate a problem with your duct work. Leaks in the duct work make your entire home warmer.
The thermostat does not work properly. You might notice that your air conditioner runs for a short time before turning off – or it doesn’t turn on at all. Your thermostat might be malfunctioning so you should have a technician check this as well.
Loud noises. If you hear grinding, scraping or squealing sounds, a belt might be slipping. This can damage other, more costly components as well, and should be fixed by a professional right away.
Increased humidity in your home. One job of your air conditioner is to reduce the amount of humidity in your house. If your house is more humid than usual even with the air conditioning on, the unit may need repair.
Bad odor when A/C is turned on. A musty smell can indicate that mold is present in the A/C unit or the ductwork. A more pungent odor can mean the wire insulation inside has burned out. You should have your unit serviced as soon as possible.
