What Different Furnace Noises Are Trying to Tell You

An efficient HVAC system should run smoothly without producing strange or audible sounds. Some furnace noises are normal, while others indicate serious issues. If something is wrong with your equipment, you must address it immediately for the comfort and safety of your spaces.

Discover some of the most common furnace noises and their causes with the help of a trusted HVAC replacement company.

Rattling Noises

Loose screws, bolts and panels can cause furnaces to make rattling noises. Professionals can tighten these components inside the unit to address this issue.

Squealing and Whistling Noises

Worn-out bearings in the fan or motor can result in squealing or whistling noises. The affected parts will have to be replaced with new ones. It’s best to leave this job to an experienced HVAC repair technician. At Stone Heating and Air, you can count on us for prompt and efficient repair service.

Booming and Banging Noises

Are you hearing booming and banging noises from your furnace? It could be due to the expansion and contraction of metal components. Your technician can fix this by lubricating the affected part so they won’t rub against each other.

Grinding and Scraping Noises

You’ll need to contact a professional immediately if your furnace produces grinding and scraping noises. It usually means something is wrong with the fan motor or other components.

Hissing and Gurgling Noises

Problems with the furnace’s intake system can result in hissing and gurgling noises. Dirt or debris blocking the air intake can cause this issue. If this is the case, you must remove the obstruction removed as soon as possible.

We had our AC go out on one of the hottest days of the year. We called as soon as they opened and they came out so quickly and offered us some loaner units to keep our babies and animals cool in the meantime. Matt was so helpful and fixed the problem quickly. He went above and beyond to help us and we will be using Stone Heating and Air to replace our unit when it’s time. They’ll be our first call in the future!
