Several factors can contribute to a burning smell coming from your AC unit. Here’s a breakdown of the most common culprits: 24 Hour Emergency Air Conditioning Service Near Me Air Conditioning Repair Companies Near Me Heating & Air Conditioning Service Near Me

1. Dust Accumulation: This is often the most benign cause, especially at the beginning of the cooling season. When an AC unit sits idle for an extended period, dust and debris accumulate on the components, particularly the heating elements and coils. When the unit is first turned on, these particles burn off, producing a temporary burning smell. This smell usually dissipates within a few hours of operation.

If the motor is overworked, poorly lubricated, or experiencing electrical issues, it can overheat and produce a burning smell. This is often accompanied by a humming sound or a noticeable decrease in cooling efficiency.
