When to Call Your Technician: HVAC Problems

When to Call Your Technician: HVAC ProblemsYour home’s HVAC system contains complicated equipment, so it can be difficult to know for sure if a developing issue is worth a phone call to your HVAC pro. Here’s a look at some common HVAC problems that deserve the attention of an experienced technician.

Unfamiliar Sounds

Some noise is expected when your HVAC equipment is running, like a hum from the outdoor compressor, a whir from the blower fan, or a pop and whoosh as air moves through the ductwork. New or startling sounds like banging, rattling, hissing or high-pitched screeching can be warning signs of serious problems, so they should be investigated immediately.

Elevated Energy Bills

Your energy bills are bound to rise if your household usage increases, or there’s a rate increase by the utility company. If your bills are climbing for no obvious reason, however, there may be a problem with your HVAC system. Some common issues that a pro should check for are an age-related drop in efficiency, dirty cooling coils, ductwork deterioration, and a low refrigerant level.

Water Leaks

During the cooling process, it’s normal for A/Cs and heat pumps to condense water from the air, but it should be sent straight outdoors through the built-in condensate drain. If you discover a puddle under your air handler, a technician needs to inspect the drainage system for obstructions or inadequate slope on the line.

Excessive Humidity

If your home always seems too warm and sticky, and you’re seeing more mold growth in moisture-prone areas like the bathrooms, your HVAC technician needs to find out why. It may be due to short-cycling oversized equipment, or undersized equipment that can’t dehumidify the space effectively.

Unpleasant Smells

Normally, you shouldn’t notice any odor in the air coming from your HVAC registers. If you’re getting a “dirty sock,” acetone-like or acrid burnt smell, call your HVAC pro to identify and correct the underlying cause. Odors like these can be related to mold/mildew growth, a refrigerant leak, or hazardous overheating/arcing of an electrical component.
