Why Does My AC Smell When It Runs?

smelly ACYou’re heading home after a hectic day at work and you can’t wait to embrace the cool comfort your couch promises.  But the moment you open your door, you’re taken aback by the foul smell that has filled your home. No! Not today! You remember your AC has been smelling for quite a while now, but it has never been this bad. Why exactly is your air conditioning unit bent on ruining your relaxation plans? Below are a few plausible explanations:

AC Smells like Mildew

This is by far the most common type of AC smell. It arises as a result of excess moisture or humidity in your HVAC system. To solve the problem, you’ll need to fix water leaks, replace your AC filter periodically, and improve drainage. A routine AC service can help you achieve these.

AC Smells like Dirty Socks

If your air conditioner smells like socks or feet, you are probably dealing with a dirty or clogged unit. When an AC unit is clogged, the water does not drain properly and the sitting water starts to smell after a while. Inviting AC repair experts to help clean your unit would help fix the problem.

AC Smells like Exhaust Fumes

This type of smell often arises as a result of a fluid leak within your unit. The fluid in your AC is also known as the refrigerant. When it leaks, it’s heated up by the hot air coming out of your unit and the result is a choking exhaust fume odor. To fix a fluid leak, you’ll need to enlist the services of an AC repair professional.

AC Gives Off a Burning Smell

If you perceive a burning smell in your house, it could be a wiring issue, an overheating motor, or some other mechanical problem. If this smell is coming from your AC, you should treat it as an emergency. Turn off the unit from the breaker box and invite AC repair professionals or the fire department to have a look.
