Modern furnaces offer reliable, energy-efficient solutions for heating your Schaumburg, IL, home. Most of the time, furnaces operate safely and effectively. According to industry experts, an annual maintenance visit will greatly reduce the risk of having a furnace breakdown. However, furnaces can sometimes malfunction even if they’ve been well-maintained. If you notice any of the following signs, you’ll need to contact a qualified professional for prompt furnace repairs.

Unusual Noises

Furnaces typically operate quietly. You may hear the furnace click when it turns on, then you’ll hear the whirring or whooshing of the blower motor pushing air through the vents. If you hear a loud or unusual humming, buzzing, banging, screeching, or grinding sound, the furnace likely has an electrical problem or a loose or damaged part that requires attention from our qualified heating contractors.

Foul Odors

The first time your furnace cycles in the late autumn, you might notice a temporary burning smell. This is the furnace burning off the dust that accumulated during the spring and summer months of the year. If the burning smell lasts for more than 30 minutes, you may need furnace repairs. If you smell a foul odor of rotten eggs, your furnace could have a gas leak. This is dangerous. Immediately leave your home and call for emergency furnace repairs.

No Heat

If you hear the furnace click on, but no air or only cold air comes through your vents, you’ll need furnace repairs. There could be a problem with the ignition, heat exchanger, blower, or gas supply valve. If your furnace won’t respond at all, it could have an electrical issue or overheated motor that triggered the safety switch to shut off the whole system. Thermostat problems can also prevent the furnace from heating your home. All of these issues require professional attention.
