Strange smells should never be ignored, especially those coming from your HVAC system. Your system isn’t meant to smell, and if it does, that could be a sign of a very serious problem. If a burning smell erupts from your heater every time you switch it on, there could be a number of possible culprits. The best thing you can do is to learn what could be causing the problem so you can put an end to it right away!
3 Reasons Your Heater Smells Like Burning Plastic
1. Seasonal Problems | Heater Smells Like Burning When First Turned On
Leaving your heater off all summer may be the cause of your burning smell. Since we only cool our homes in the summer, the heater tends to collect dust and debris during the warmer months. When the cold arrives and we fire up our heaters, all that built up dust burns off, emitting a burning odor. This smell then gets sent through your vents and into your entire home
This is generally a problem that will only happen once a year, when you first turn on the heat for the winter. However, if you want to prevent this unpleasant stench, don’t skip your annual maintenance. You HVAC technician will clean your entire system, preventing this problem.
2. Clogged Air Filter
If it has been a while since you changed your system’s filters, then it could be another reason for that burning smell. Clogged filters make your heater’s motors do double the work. When this happens, the motors can start to emit that burning smell that is flowing through your house. Be sure to change your filters regularly and always change them at the start of a new season.
3. Electrical Malfunction
Sometimes, it’s more than a lack of maintenance causing the burning smell. If your heater is still letting out a smoky odor after its initial startup for the season, it could be a sign of a much bigger problem. Electrical shorts and other malfunctions may be occurring in your heater, leaving your HVAC unit and home in danger. If you have a constant smoky smell coming from your vents, turn off your system and call an HVAC professional at once.
