Common Noises & Issues You May Experience with Your AC
Many homeowners wonder what sounds they should hear when their air conditioning is running. A well-tuned AC system that’s running efficiently should be relatively quiet indoors. You should hear little more than a light humming sound when it turns on and off. In fact, newer air conditioner compressors are designed to keep the noise levels less than 55 decibels. Your air conditioner’s outdoor unit will produce loud noise when it’s running, but the sounds should never be shrill or clanging. If you notice any unusual sounds coming from either the indoor or outdoor unit, you may need an AC repair, or even an AC replacement at this point. The trained professionals at Merts Heating & Air Conditioning can help with that. You won’t have to worry about your AC being loud ever again!
So, What’s Making My AC So Loud?
Light humming is normal when the system turns on and off, but if you’re hearing a loud and constant humming, that’s an indicator of a possible electrical problem inside the unit. If the sound you’re hearing is like this, don’t turn your unit on until a technician inspects it. Running your AC with an electrical issue will cause bigger, more expensive problems and maybe even cause the need for an AC replacement.
Banging noises from inside your air conditioner could indicate a broken or loose part inside. If this is the case, it’s likely a component of the compressor, which means the compressor will need to be replaced.
Hissing sounds could indicate a variety of issues from leaking ductwork, a faulty expansion valve or even just an air filter that isn’t properly suited for your system. Contact Merts right away and one of our technicians will inspect your system and take care of the problem.
WHIRRING, HELICOPTER-LIKE SOUNDS
If you’re hearing sounds like a helicopter whirring overhead, the issue could be indoors or outdoors. The malfunction might be due to bad bearings, a bad fan, a torn or ripped belt or even because debris is caught in the outdoor unit. A thorough inspection of your system will locate the problem and can likely be fixed with a minor AC repair.
