5 Reasons Your AC Smells Like Burning & How to Fix It

1. Dust Burning Off

One of the most common problems we notice with AC units is a build-up of dust when it hasn’t been used for a few months. This is a common issue in areas where the weather in the winter months doesn’t require you to use the AC as much as you would in the summer. When you turn on the AC unit again for the first time in a while, it will likely smell like burning. The good news is that this smell should disappear within just a few minutes. However, if you do find that the smell persists for longer, then it’s time to get in touch with our team as there may be a more serious issue.

2. Clogged Air Filter

Another reason that your AC smells like burning may be due to the fact that you haven’t changed your air filter in a while. When too much dirt and debris build up on the filter, airflow will be more restricted. This can put a huge strain on many components of your AC system, resulting in this burning smell. We recommend changing your air filter every month or so in the future so you don’t experience this concerning smell again.

3. Overheated Motor

Faulty parts are often to blame for your AC smelling like burning, particularly when it comes to experiencing an overheated motor. This can give off a burning smell when the bearings of the motor have started to wear out. You can overcome this issue by lubricating the bearings, which will stop the motor from burning out. In some cases, you may find that you need to replace the motor completely, but our team will be able to assess your AC unit to see if this is necessary for you.

4. Broken Capacitor

A capacitor is a part that helps to power the motor, but when it overheats, you may notice your AC smells like burning. There are many different reasons that a capacitor can break, including a power surge or just general overuse after a long period of time. You’ll need to go ahead and replace the broken capacitor for it to function properly again. A professional team such as ours will be able to help with this task, but make sure you turn off the AC unit in the meantime to avoid further issues.

5. Burning Electrical Components

Burning smells coming from AC units sometimes smell of sulfur, which can be a sign that there is a more serious electrical failure within the system. A lot of plastic is used in an AC unit, which surrounds the wires in the system. When these components start to wear out or are defective, then they may burn the casing surrounding them. If you think this may be the reason that your AC smells like burning, turn off the system and call our team straight away.
