Why Does My Heater Smell Like It's Burning?

Combat Furnace Smells With HVAC Repair

Coming home to a burning smell is frustrating and downright scary. However, when you discover your heating system is the cause of the smell, it can occasionally be a cause for concern.

At Air Tech of Conroe, we have all of the furnace expertise and equipment you need to keep your house warm. With five-star AC and heater services, you know that you’re getting the best HVAC services for your home. Read ahead to learn a few causes of this odor coming from your heating unit.

What Causes A Burning Smell From Heaters?

There are a few common reasons why your heating system is producing a burning smell. Understanding these different causes can help you determine when to contact our team for assistance.

Dirty Furnace

One of the most common reasons for this smell is dust accumulation. If your furnace hasn’t been used in a while, dust will build up on the heat exchanger, burners and other necessary components.

When you turn on the heater with this dust resting in the unit, it will start to emit a strong, burning smell. This isn’t typically a cause for concern since the smell should go away after 30 minutes to an hour. However, if the odor persists, it’s best to contact an HVAC professional.

Overheating Components

Another reason for this smell is overheating components within the system. If your air filter is dirty or clogged, it can restrict airflow. This causes the furnace to overcompensate for the lost air, overheating the system.

Electrical Problems

If the burning smell is sharp and plastic-like, it could indicate a serious electrical problem. This signals that your writing is faulty, frayed and overheated. Faulty wiring is a serious issue that can lead to electrical fires if not addressed as soon as possible.

Signs You Need Professional Furnace Repair

Other than a burning smell, there are a few additional signs that indicate a need for heating repair. Monitoring your system for these issues can help you understand when it’s time to call in our technicians for help.

Significant Increase In Energy Bills

One of the most common signs that your unit needs repair is when your energy bill starts skyrocketing unexpectedly. If you’re using your furnace the same amount, but your bills are higher — your system is not operating efficiently.

Unusual Noises and Smells

Heaters usually make some noise whenever they start up or turn off, but unusual noises such as squealing or popping may indicate a mechanical issue in the system. Any abnormal smells are signs that your furnace needs immediate attention. It could be something as serious as a gas leak, which poses a risk of fire or explosion.

Difficulty Starting The Unit

If your unit is having trouble turning on, it is a clear sign that you should call a professional for repair. This problem could be caused by anything from a faulty thermostat to issues with the furnace’s wiring.
