3 Furnace Odors and Their Sources in Garner, NC

It is very uncomfortable to stay in a house with unpleasant odors. A faulty furnace may be the cause of weird odors lingering in your Garner, NC home. Different furnace odors typically indicate problems, so it’s important to know how to recognize them.

1. Rotten Eggs

If you have a gas furnace, a lingering rotten-egg smell means your natural gas is leaking. This is not only a sign of furnace problems, but it’s also very dangerous. Since natural gas is odorless, gas companies add a chemical that smells like rotten eggs or sulfur to help homeowners tell when this gas leaks.

If you notice this odor coming from your furnace, it’s important to act quickly. Shut off the main power source to the furnace and get everyone out of your home until a professional repair tech arrives.

2. Mustiness

Biological contaminants may grow in your ductwork or other places in your furnace. These pollutants release spores into your living space, causing a musty smell and creating poor indoor air quality, which can lead to problems such as watery eyes, throat irritations, sneezing and headaches.

The pollutants thrive on moist surfaces in your furnace. Hire a technician to clean all your system’s components to eliminate these contaminants.

3. A Burning Smell

If your furnace’s wires become loose, they may come in contact with the hot parts of the system. The hot parts melt the coating on the wires, causing a burning plastic smell.

You may also detect this smell if the furnace overheats. Some of the issues that may make your system overheat include a clogged air filter, ductwork leaks, an undersized system, insufficient lubrication, and blocked vents.

Seek professional help immediately if you detect foul smells from your furnace to have the underlying problem addressed early. You can call Airmakers Heating & Cooling, LLC for exceptional heating services. Our technicians are always ready to help.
