What's That Sound Coming From My Furnace?
If there's a sound coming from your HVAC unit, chances are you should stand up and take notice. These systems generally operate in total silence, circulating warm and cold air throughout your house at the appropriate times.
A loud sound coming from your furnace should warrant at least an inspection, and if necessary, a call to a heating repair service. The last thing you want is for your unit to go out in the middle of the winter, leaving you and your family without the necessary heat to stay warm. Read on to learn more.
Banging Sound
One of the most common sounds that customers report coming from their furnace is a constant banging sound. While it may sound scary, the reason is actually very simple. When the furnace is in use, the system vibrates ever so slightly, and will eventually shake the bolts on the furnace covers loose. That banging sound is usually the bolts bouncing around inside the ductwork. If it's not fixed, you could end up with a broken furnace on your hands, as gunk and debris will enter into the system and clog up your system.
A Single, Loud Pop
If what you hear isn't a constant banging sound, but rather a single pop every so often, then it's most likely the result of dirty furnace burners. These can cause gasses to build up inside the unit and then create a tiny explosion once the ignition fires. That may sound dangerous, but it usually only affects the ductwork. Still, it's worth calling for basic heating repair services to clean out the burners.
Squealing Noise
Squealing noises can have a lot of different explanations, but it almost always signals that a part needs to be replaced. It could be that a belt is getting worn down or that the fan blade is having to work harder to spin and remove the warm air. The same is true if you hear a screeching noise, which is caused by metal rubbing together and comes from constant overuse. Although air conditioning units can last a decade or more, the parts that keep the heating system together may need to be repaired or replaced long before the unit fails. A heating repair specialist can change the offending parts out pretty quickly, leaving you with a strong and silent heating installation that delivers warm air whenever you need it.
