There are a few signs that your home AC compressor may be starting to fail. If you notice any of the following, it’s worth having a professional take a look:
–The AC unit isn’t cooling your home as well as it used to. This could be because the compressor isn’t running as efficiently as it once did.
–You hear strange noises coming from the AC unit, or it seems to be working harder than usual (e.g., the unit is cycling on and off more frequently).
–Your energy bills have gone up, even though you haven’t made any changes to your AC usage. This could indicate that the compressor is working less efficiently and using more energy than it should.
