What Is That Burning Smell Coming From My AC?


No matter where it’s coming from, a burning smell within your home is alarming, and although you may have just burnt your toast, a far more serious issue could be brewing. There are several factors that could cause a burning odor to come from your HVAC system. The issue may be as easy to solve as changing your air filter, but it could also pose a risk for an electrical fire. Here are some possible scenarios that may cause a burning smell to come from your AC and how to fix them.

There’s a Burning Smell Coming From My Air Conditioner

If you have the air conditioning on, and not the heat, a burning odor could be a sign of an electrical problem. Loose electrical connections and electrical failures could cause parts of your AC, such as the blower motor, to overheat. When parts of your AC overheat, the plastic insulation on electrical wires can melt, causing a burnt-plastic smell. Electrical failures anywhere in your home can be dangerous, so be sure to turn off your system completely and call an AC professional.

There’s a Burning Smell When I Turn On My Heating System

A burning smell coming from your heater is actually fairly common, but only if you’ve just cranked it up for the first time in a while. When your heating system sits idle over the warmer months, it may have acquired some built-up dust and debris. When you first turn your heating system on, it burns through the layer of dust, creating an odor. If the smell does not go away soon, you’ll want to contact a professional. There could also be a mechanical failure or a foreign object interfering with your equipment.

The issue could also lie in your filter if you haven’t changed it in a while. Be sure to start every month with a fresh air filter in your system. A clogged filter could restrict airflow and cause parts to overheat. Switch out your filter and see if it helps.

In any case, if the burning smell persists beyond the first day or two of using your heating system, have an AC professional check things out.
