A burning smell from your AC is not a minor issue you can ignore. The last thing you want is a malfunction or safety hazard in the middle of summer when you need cool air the most. While there are several reasons your HVAC can smell like burning, it is advisable to consult a professional to eliminate uncertainties. Seasoned technicians can inspect, diagnose, and address the problem before things get out of hand. Let’s look at common causes and how to fix them.
Burnt Dust
When you notice a burnt smell coming from your AC, it could be burnt dust from the heater. When you turn on the heater for the first time after a while or after returning home from a trip, the built-up dust burns off, which produces a burning odor in the room. While this smell is harmless, it is advisable to stay outdoors or in another room for several minutes until it clears. If the odor persists, it shows a more severe underlying problem that may require professional expertise.
Clogged Air Filter
After a successful HVAC installation, most people rarely think of their systems until something happens. Filters are crucial components that trap dust and other contaminants in the air, ensuring a safe and comfortable environment. Over time, filters can clog, restricting airflow, which in turn overworks the motors. This can result in a burning smell from your AC when it is running. Filter replacement is usually a straightforward task for DIYers, but routine inspections by an expert are vital.
Broken Capacitor
Another reason why your AC smells like burning is a broken capacitor. This is a critical component that powers the motor and may overheat when broken, releasing a burnt smell. There are many reasons for a broken capacitor, such as general wear, power outages, or an overheated circuit system. In addition, electrical shorts can be the reason for the burning smell from your AC. Call a technician for a comprehensive inspection to pinpoint the issue, determine the severity, and recommend a practical solution.
