Furnaces aren’t exactly known for having a fresh smell, but you’ll immediately notice something is off if your unit smells strange when you turn it on. These odd smells aren’t universal though, and it’s important to be able to distinguish the sources in order to properly address the issue.
In this post, your heating and air conditioning maintenance experts at Home Air Services share about different furnace smells and what they mean.
A dusty or musty odor is the most common furnace smell and often manifests during the colder seasons. It’s caused by dirt and dust clogging the filters, which can affect the unit’s ability to run as efficiently as possible.
To take care of this problem, simply replace or clean the air filter and the smell of burning dust will be no more. For larger furnaces, it may be a good idea to get in touch with your local duct cleaning companies – especially if the dust and dirt buildup extends beyond the filter.
A burning electrical smell may be the result of an overheated furnace motor, which occurs when the bearings have worn down significantly. If you notice this odor, immediately turn off the unit, as an overheated motor can become so hot that it melts the wires. Call your local heating company and have it checked so they can properly address the issue.
A furnace that has a strange chemical smell probably has a cracked heat exchanger. This is a serious problem, as it may allow carbon monoxide to enter your home through the ventilation system. Call your local HVAC company as soon as possible if you notice this smell, and vacate the premises if your carbon monoxide detectors go off.
