When the house is quiet, and you are trying to sleep, the sounds of popping, scraping, or squealing are usually sounds. These noises can potentially be coming from the furnace. If you believe the unusual noises are coming from the furnace, it is better to let a professional identify the source of the find. The probable reasons as to why your furnace is making these noises is what we New York Air Conditioning & Heating would like to share today.

Wheezing Furnace Sound

Your furnace is the likely culprit if you hear a wheezing sound floating around your home. A dirty air filter could be the cause of the wheezing or whooshing sound. If your air filter is left for too long, it will inevitably get full of dust, dander, and other particles from your indoor air. When the air filter is too full, your furnace needs to push air through the grit. The treated air pushing through the full air filter is the wheezing noise.

Furnace Whining when it Turns On

If you ever hear an unusual squealing sound coming from your furnace, chances are something is wrong with the blower belt. The belt is worn out, misaligned, or in need of lubrication. An HVAC tech can look at this and diagnose it during a routine tune-up.

Furnace Making a Loud Scraping Noise

A pretty distinctive sound most people recognize is metal grinding against metal. That’s a red flag you need to schedule an HVAC appointment immediately if you ever hear it. It is either a broken motor mount or a broken blower wheel when you hear scraping noise is attributed to one of two things. The unusual furnace sound checked out immediately if a broken or loose blower wheel can cause major damage to your entire system. The blower wheel can be affected by a broken motor mount. When the motor mount is damaged, it can’t hold the blower wheel in place.

Banging, Booming & Popping Furnace Noises

The furnace may make a boom or popping noise when it’s first starting up. It is highly likely that your furnace burner is dirty. When the flame finally ignites, a gas buildup occurs when the furnace burner is clogged with dust, dirt, or other obstacles, which then makes a popping noise. your metal ducts could be expanding and contracting with the changes in temperature, causing the booming banging, or popping noises. This is completely normal and nothing to be concerned about if your home is equipped with metal ductwork.

Furnace Pinging Sounds

As we noted, your ductwork expands and contracts with temperature changes. When you hear ping, ping, ping noise, your ductwork is doing its job.

Crackling Furnace Noise

May be nothing to worry about, otherwise crackling noises are almost concerning, if they’re coming from your furnace. After your furnace is off, it is completely normal if you hear a crackling sound coming. As it cools down and turns off, the ductwork and furnace itself will make crackling noises.
