When it’s working well, your air conditioner produces cool, odorless air to keep your home comfortable. However, if it starts to emit a foul odor, contact an HVAC contractor to determine the cause. Harsh smells of any kind aren’t normal, and the underlying factor might require prompt repairs. Here are several common reasons it may happen.

Why Does the AC Produce a Bad Smell?

1. Component Damage

If you smell something burning when you turn on the air conditioner, it could be due to an electrical or mechanical malfunction affecting one of the device’s components. This can cause the motor, compressor, or fan to fail and ruin the wires, which is a fire hazard. For example, if the motor’s bearings lose their integrity, the part will overheat and produce a strong odor. The same situation can happen if the capacitor—which powers the motor—fails. An HVAC contractor can quickly detect and resolve this problem before it leads to significant safety concerns and electrical shortages.

2. Mold Formation

If you notice a musty or mildew-like smell in the air, it could be due to mold buildup. Condensation accumulates inside air conditioning systems because of the cold, fresh air that they circulate. The lingering moisture provides a hospitable environment for mold, which is a potent allergen that only takes 24 to 48 hours to develop in the right setting.

The issue occurs when the moisture enters the air ducts, and it can spread whenever you turn on the AC. To resolve this problem, you should remove the mold, clean the ducts, and lower the moisture in your home.

3. Gas Leak

An odor reminiscent of rotten eggs is both potent and concerning. This is typically a sign that there’s a natural gas leak on the premises. To be safe, open your home’s windows, go outside, and call your gas company and HVAC contractor promptly. This will ensure that your family remains safe and prevents symptoms that arise from inhaling the gas, such as headaches, nausea, and dizziness.
