Why Does My Furnace Smell Like It’s Burning?

It’s December, and while the winter season doesn’t bring subzero temperatures and heavy snowfall in this part of the country, things have definitely started cooling off. Looking at upcoming temperatures, there are a lot more 60’s than 70’s in the forecast, and plenty of 30’s on the low side of things. No doubt about it now. It’s your heater’s turn to step up to the plate.

Some homeowners underestimate just how important their heating  systems are around here, due to the fact that winter is pretty mild. We’re here to tell you that you cannot afford to ignore signs of trouble with your heater. Not only do you put your comfort at risk in doing so, but potentially your safety as well.

What’s Behind This Burning Odor?

Like most heating problems, there are a few different reasons as to why your furnace in Mesa, AZ may emit a burning odor. Not all of the potential causes are terribly serious. Because others are, though, you should always take prompt action and have the system professionally evaluated. It may be:

  • Dust. This is one of 2 best case scenarios. During the off-season, which is obviously very long in Arizona, your furnace may accumulate dust on its burner or electrical heating element. When you activate your furnace for the first time of the year, you may smell that dust burning off of the system.
  • Air Filters. This is the other one. If you have a very dirty air filter in your furnace, change it! You should be doing this every 1 – 3 months, generally speaking. Don’t leave it for annual maintenance. The system could overheat due to increased air flow resistance, which could lead to damage.
  • Blockages. Do you have any kids? If so, you know how curious (and mischievous) they can be. It’s possible that a toy or some other object somehow found its way into an air vent. If so, a professional can find and remove it.
  • Electrical Problems. This is a far more serious issue, and poses a fire hazard. If your wiring is getting too hot for any reason, and melting its insulation, you need the problem resolved immediately. Don’t let electrical problems with your furnace lead to a dangerous situation.
