Most people don’t think about their HVAC unit until its broken, which is too late.  Here are five helpful warning signs that your unit may need servicing by a certified heating and cooling technician.

It’s Not Cooling:

The most obvious sign that your HVAC needs help is that it’s not cooling. Your HVAC technician will check for the three primary causes:

Evaporation coils: They may be clogged, if there clogged with dirt the system will not cool properly and you’ll be hot.

Leaking refrigerant: Your technician will have to run a test to locate the source of the leak and fix it for your system to start operating at its full capacity.

Leaking ducts: If you have a leak in your duct, the cold air that should be keeping you cool is spilling into the attic, between walls, or outside your home.

Making Weird Noises:  

The cause of unwelcome noises could be a loose fan, screws that need to be tightened, clogged coil fins or parts that need lubrication.

Your Bill Goes Suddenly Up:

Your electric costs should be about the same this month as they were in the same month a year ago. If you notice a big change, chances are something is wrong with your HVAC system.

It Smells funny:

If you notice a foul odor coming from your vents, you could be experiencing a problem which results from bacterial growth within the HVAC system vents.

It’s Leaking:

If you notice any discolored circles on your ceiling, dripping or puddling near your unit, you have a problem. The cause for the leak could be an overflowing pan, clogged filter or backed up condensate line.

If you notice any of these problems with your system, it’s time to call a certified technician.
