Even if your AC has been running smoothly, it can still produce weird smells that you should be aware of. Below are some reasons why your cooling system may smell odd and what you can do about it in Frederick, MD.

1. Dirty Evaporator Coils

The accumulation of dirt on the evaporator coils can become a breeding ground for biological growth. As the air passes through your AC, these particulates can spread throughout your home, producing a musty or acidic smell. Having a qualified HVAC tech to clean them will keep the air clean and safe to breathe .

2. Full Drain Pan

Water droplets from the evaporator coils can collect in the drain pan beneath your system. If you don’t empty the pan frequently, this can cause pathogens to produce, causing an unpleasant smell. Carry out frequent AC maintenance of your system to avoid this situation.

3. Blocked Condensate Line

A blocked condensate line causes water to back up and overflow from the pan. This will lead to a sour smell in your home due to biological contaminants. The best course of action is to keep up with routine maintenance.

4. Poorly Sized AC System

Sometimes, an AC system that’s too small or too large for your home may lead to poor performance. If the system is too large, it may not be able to dehumidify your home adequately, resulting in high humidity and a musty smell. If it’s undersized, the air may not be able to circulate properly, leading to stale air and funky smells in your home.

The odors from your AC can cause headaches, allergy symptoms, and other side effects. If you’re experiencing a weird smell from your AC system, contact Eric Smock Heating & Air Conditioning, Inc. for top-rated AC repair services and indoor air quality solutions.
