Sound Check

You may be noticing more sounds coming from your air conditioner these past days in these extreme El Paso temperatures. That’s because it is working overtime.

There are sounds that the A/C makes that are normal, but they are also some that are not. Knowing the difference can save you on repairs and possibly an early retirement of your HVAC system. Here are some sounds you could be hearing, what they may mean, and if you should call Longhorn Maintenance Heating and Cooling for service:

Bang Bang Bang

Light banging may mean that something has come loose in the compressor like a rod or a piston. It could also be the compressor itself. Either way, this requires a check up from Longhorn Air to fix.

Screeeeeech

A metal on metal screeching sound may mean you have worn out bearing in the fan motor. This requires a repair from Longhorn Air to fix.

Squeal

A squealing sound may mean you have a misaligned or worn fan belt. It will need replacing the professionals at Longhorn Air. High temperatures and humidity, like we are experiencing in El Paso these past couple of weeks, can wear on a fan belt eventually causing it to break.

Click. Click. Click.

Like a playing card in the spokes of a bicycle, a clicking sound may mean you have a stick or some other obstruction that has fallen into the condensing unit and is hitting the fan blades. Try turning off the A/C and clearing the obstruction. If that doesn’t work, you may have an electrical problem (especially if the A/C will not turn back on). If that is the case, call Longhorn for a repair or estimate on a replacement.

Hummmmmmm

A humming sound can be many things. While some humming is normal in heavy use periods, continuous humming is not. It could mean you have loose wires, an electrical problem, or a blower motor issue. Call Longhorn Air to troubleshoot the hum if it doesn’t go away on its own.

Whistling While it Works

A whistling or wheezing sounds may simply mean you need to change the air filter. Or, in heavy use periods like this week in El Paso, open those vents that you have closed too much to let airflow pass through. They are trying to pass more air through to those living spaces because the extreme heat has made it hotter in those spaces than normal.
