Early Warnings You May Need AC Repairs


As your air conditioner starts to get to work during the spring and into the summer, it’s a good idea to watch carefully for indications the AC is working right or is building up to a larger malfunction. The best way to ensure your air conditioner won’t run into problems during the early season or through the rest of the year is to schedule regular professional HVAC maintenance. You can sign up for our maintenance plan to schedule this service if you haven’t done so already.

No matter what, you should still look out for those early warning signs to call one of our service champions to have air conditioning repair in Malvern, PA. Below are the major signs:

Unusual noises

You have an idea what your air conditioner sounds like when it runs if you’ve had it for a least a month. It’s mostly white noise from fans and motors, with a change in sound when the compressor turns on. All well and good. But when this standard noise is interrupted by something like grinding, hissing, mechanical shrieking, clanging, or rattling, it probably means something needs to be fixed. Leave it to the HVAC experts to diagnose what’s wrong and repair it.

Low airflow from vents

When the air conditioner first starts running, walk to all of the rooms and feel the airflow coming from the vents. If the airflow feels weaker than usual, it may indicate trouble with the blower fan, a clogged air filter (which you can change yourself), or leaking from the air ducts.

Hot spots

You’ll probably notice soon if one of the rooms in the house isn’t as cool as it should be—or you’ll hear from somebody in the house that their room isn’t as cool as it should be. Uneven cooling is one of the bigger warnings that an AC is starting to lose its capacity for some reason.

The first month of bills is too high

When your first electrical bill for the warmer season arrives and it looks … steeper than normal, that’s a cause for concern. You might be able to account for the rise with increased use (such as, well, staying home a lot more than normal). If you can’t account for it, however, it’s best to have HVAC technicians look into it.


This term refers to when an air conditioner’s compressor shuts off early before completing its cooling cycle and then turns back on again a short time later. This on-off-on-off rapid cycling puts extra strain on the system, doesn’t give the cool air enough time to spread around the house, and increases bills. There are also many possible causes, so we recommend calling our team to find out what’s behind the short-cycling.
