Concerns about strange furnace sounds and odd smells shouldn’t go ignored. Do you hear clicking sounds like someone’s using a typewriter? Do banging noises stop you in your tracks when the furnace turns on? If you hear or smell any of the following when operating your furnace, call a qualified HVAC service technician in Lafayette, LA, right away.
Booming Sounds
Booming sounds signal small explosions happening inside the furnace. Dirty burners cause this problem. Extra gas builds up because the dirty burners hinder the ignition process. Once the burners ignite, the built-up gas makes a booming sound. Keep your burners clean to prevent more expensive problems in the future.
Furnace Smells Like Rotten Eggs
Never ignore a furnace that smells like rotten eggs. The sulfur smell indicates a gas leak. Gas companies add the sulfur odor to the gas to make it easier for you to detect deadly gas leaks. Gas furnaces with bad components are most at risk of gas leaks, so don’t put off making repairs. Call the gas company to detect the leak and then have qualified HVAC service technicians fix the problem.
Scraping Sounds
Screeching or scraping might only seem annoying but don’t ignore these furnace sounds. The most common reasons for high-pitched sounds include a broken blower wheel or another motor part that’s come loose and is smacking against the furnace casing.
Furnace Smells Like It’s Burning
Not all burning odors signal a problem. The first time you turn on the furnace at the start of the heating season, you might notice this smell. The odor comes from dust buildup on the burners. The smell should go away on its own after one or two heating cycles. If it doesn’t, call for furnace repair service.
The sooner you call for service to diagnose strange furnace sounds and odors, the better. Waiting too long can lead to costly repairs and untimely replacement. To schedule professional heating repairs, call Desormeaux's Heating & Air Conditioning.
