Why Does My Furnace Smell?

September 19, 2016

If your furnace emits an odor of any sort, it is cause for concern. Though gas and oil furnaces will often produce a faint scent of burnt fuel, if you smell an odor any stronger than that, it will usually require furnace repair service from an HVAC professional. Let’s take a look at the different types of furnace smells and explain what they indicate—or contact Rick’s Heating & Cooling for furnace services in the Cincinnati, OH area!

Smells Your Furnace Gives Off & What They Mean

1. Electrical Scent

Electrical smells stemming from the furnace should not be shrugged off. Though each instance of this scent does not indicate the same problem, it is a clue that something is wrong with the furnace. If you notice a metallic or electrical smell like burning wires, there is likely a problem with the furnace’s internal components. These components might be overheating.

In some instances, the electrical odor will result in the furnace shutting itself off. This is a safeguarding mechanism that disables the furnace from operating in order to prevent further damage. Such an odor is also an indication that metal/rubber parts within the furnace are burning as a result of wear and tear. If you smell this odor, shut off the furnace right away and contact Rick’s Heating & Cooling for assistance.

2. Rotten Egg Smell

A furnace that reeks of rotten eggs or sulfur is typically an indication of a gas leak. The majority of gas companies intentionally scent their gas with this scent to tip off homeowners and technicians of a leak. The odor of rotten eggs in a home has the potential to cause a fire or an explosion as gas has infiltrated the air.

If you smell rotten eggs, turn off the furnace and open the windows to allow clean air inside your living space. Contact your local fire department and utility provider for immediate assistance. The reach out to Rick’s Heating & Cooling for a thorough evaluation and tune-up of your furnace to ensure that a similar problem does not arise in the future.

3. Burning Odor

If your furnace emits the odor of burning dust, do not panic. This is one of the most common furnace smells. The odor might be the result of the furnace being turned on for the first time in months. The furnace has to burn away dust, dirt and other built-up debris from its insides. If the burning odor lingers, it is an indication that professional assistance is necessary from HVAC experts. There could be a serious problem with your heating system. Or, it is possible that the air filter needs to be replaced.

4. Musty or Damp Fragrance

If water enters your home from sources outside of your HVAC equipment, it could produce a damp or musty odor when the unit is turned on. If the smell lingers, it might be necessary to have a professional HVAC expert check out the return ducts for air leaks. Furthermore, the repairman will examine the air handler and inspect your home’s HVAC equipment for water damage. If running a dehumidifier doesn’t eliminate the damp or musty odor in a day’s time, do not hesitate to reach out to Rick’s Heating & Cooling for professional assistance from the experts.
