AC Unit Smells

Why Does My AC Unit Smell?

September 4, 2018

When your air conditioner blows cool air into your home in The Villages, Florida, you don’t expect it to smell strange. While most odors are embarrassing, annoying or just plain bothersome, others may indicate a problem with your HVAC system. Here’s why your AC unit might smell and how to take care of the problem:

Stale Air

If your filter clogs with dirt and other particles, it can’t filter your air properly. As a result, it’ll become stale. Changing the air filter might eliminate the odor, and it’ll also help your air conditioner run more efficiently.

Small Animals

Small animals have been known to sneak into air ducts and not get out. If you smell rotten eggs when you turn the air conditioning on, an animal may have died in your ducts and is decomposing. An HVAC professional can clean your ducts and eliminate any lingering smell from a dead rodent.

Sewage

Having a blocked sewer line or damaged sewer vent pipe may result in methane gas making its way through your HVAC system. As a result, it can cause your home to smell like sewage.

Exhaust

If your HVAC system’s components are leaking any fluid, you may start to smell an odor similar to that of exhaust fumes coming through your vents. Contact an HVAC professional immediately to evaluate and fix the damage.

Short Circuit

If there’s a short in your circuit board or fan motor, you might notice a smell like that of gunpowder. You’ll need to replace a part, and a professional HVAC service technician can help you.

Breathing in bad smells that are emanating from your air conditioning system aren’t just annoying. They can also indicate a problem with your system.
