HVAC equipment issues seem to pop up when you least expect them. And one of the most common ways a homeowner can detect a problem is by listening. A properly operating AC system is designed to run fairly quietly, with only a slight humming sound. But when a problem begins to develop, you might hear some irregular noises:
- Rattling or Tapping – The first thing you should do is check your equipment for branches or other debris that may have gotten caught. If you are going to try and remove these, make sure your system is shut off for your safety. These noises can also be caused by equipment that has come loose. Rattling and Tapping sounds may not inhibit your system’s operating efficiencies in the short term, but leaving the situation unchecked can lead to further problems, like damaged equipment.
- Hissing – This type of sound is usually in connection with a leak from your equipment. If your system is leaking refrigerant, shut off your equipment and stay clear of where the sound is coming from. A system low or without any refrigerant will not function properly. Call a local professional to inspect this sound immediately.
- Squealing – This type of sound is generally heard when there is an issue with a belt or motor bearing. This is a likely precursor to a larger problem and should be addressed by a local professional. If identified early, these are usually quick repairs. If left unresolved, they can snowball into problems resulting in more expensive solutions.
Even if your equipment appears to be working – if you should hear some irregular noises, that’s your equipment telling you something might be wrong. Don’t wait until it’s too late. Invite a local HVAC professional, like Levco to inspect the equipment and let you know exactly what’s going on. Early resolution to a problem can sometimes save you from an expensive repair or replacement bill.
