Many homeowners are starting to use their heaters since the weather is getting cooler.  Sometimes homeowners can smell an odor that is being emitted from their furnace and ignore because they think it is normal. A furnace unit that produces odor that is out of the ordinary must be checked immediately because this is unusual. Keep in mind that some smells coming from the furnace indicate a serious problem that should never be ignored. Here are some of the most common odors that require your attention:

Dusty Odors

The only unpleasant odor that should emanate from a furnace is a dusty smell, often the result of the unit being switched on after a long period. The good thing about dusty smells is that they disappear eventually as the furnace burns away the dust. However, if the smell persists, have your furnace checked immediately to find out what the problem may be.

Natural Gas

Natural gas in its basic state is odorless, so to make it easy to detect, a scent is added to it by utility companies to make it noticeable. This scent is similar to that of sulfur or rotten eggs, or an odor that we have closely identified with natural gas. A strong odor coming from the furnace is an emergency situation because it means that there is a leak. Should this happen, open the windows to bring in fresh air and allow the gas to dissipate. Get in touch with the utility company to inform them of the problem, then leave the house immediately. Accumulation of natural gas within an enclosed area increases the risk of a fire or an explosion, so vacate the premises and stay as far away as possible.

Metallic Odor

A metallic odor is often an electrical problem and something that many homeowners readily recognize. This type of smell is often caused by faulty and overheating parts. Often, this can be traced to a malfunctioning blower motor, which in turn may be traced to faulty bearings. Once this happens, the motor overheats and burns the insulation on the wires. Metallic odors may also be caused by loose relays or connections.

Overheating may also be caused by dirty filter. If the air filters are not maintained, blockage can restrict the flow of air, causing an increase in the temperature within the furnace. When the air filter is dirty, it’s time to change it.

When detecting a metallic odor, you should shut down the furnace right away. Then, call the HVAC contractor to have the unit inspected. While waiting for the technician, observe the furnace to check if a fire breaks out and be ready to put it out in case it starts.

Burning Odor

A burning odor is a more intense version of both the electrical and metallic odor. This usually happens when wires and parts become overheated. Smoke may or may not be present. A burning odor may also be caused by debris that enters the unit via the duct work. If it comes in contact with the heat exchanger, the heat may burn the debris, thus causing the smell. If you detect a burning odor, shut down the furnace right away and call your local emergency services.

Oil Odor

An oily odor that comes from the furnace is usually caused by a leak or a problem with the oil burner. There are times when an oil leak is an easy fix, usually requiring only a fitting to be tightened. If a leak is not present but an oily odor remains, the burner may be the problem. Burner issues are caused by a number of problems, so it’s best to call the professionals for a proper inspection.
