Is Your Heat Pump in Mount Pleasant, TX, Crying Out for Help?

As your heat pump cools your home in Mount Pleasant, TX, it shouldn’t make disrupting noises. At the most, you may hear some rattling or clicking upon start-up, but any other sound will indicate trouble with the heat pump. The following are four common noises that should alarm you enough to schedule a repair right away:

Rattling or Banging

Loose screws and electrical panels can cause a continuous rattling noise, and if the issue escalates, it can create a more insistent banging noise. If you hear banging from the start, tthe fan blade may be hitting against something that has become loose inside the air handler. Or, it may be hitting ice that has developed on account of low refrigerant levels.


As a part of maintenance, you can usually get the bearings of the blower motor lubricated. This is an important task because without lubrication, the bearings will create friction and cause the system to overheat and shut down prematurely. Before that happens, though, the bearings will emit a grinding sound, which can serve as a warning.


Gurgling or hissing imply low refrigerant levels. You need refrigerant to transfer heat, so if you’ve experienced lukewarm air lately, this could be the culprit. The refrigerant charge may have gone down because of a leak, which is a health and environmental hazard.

Buzzing or Vibrating

A loose electrical panel may buzz or vibrate, as could a refrigerant line that has become tight. The worst-case scenario is that the air handler as a whole has become bad, which could mean replacing the entire heat pump.
