Many homeowners will be flying during the holiday season, but that doesn’t mean you should be bringing your air travel home with you! If your furnace makes a loud noise when it turns on that reminds you of being squished in the middle seat on a long domestic flight to visit the in-laws, there could be something wrong.
Strange and loud furnace noises are among the most common reasons why New Jersey and Pennsylvania homeowners call Princeton Air for furnace repair. Today we’re going to explain the reasons why you are hearing a furnace noise all of a sudden, and what you can do to fix it.
Types of Furnace Noises
The first thing you should do is figure out what kind of noise you’re hearing, very similar to the way you would describe a noise to a car mechanic. Which of the following best describes the sound you are hearing:
- Low rumbling
- High pitched whistling
- Rattling
- Booming or banging
- Screeching
Narrowing down the type of noise your furnace is making can help a furnace maintenance and repair technician localize the issue and properly diagnose it.
Furnace Issues that Cause Loud Sounds
Ductwork problems
Sometimes what homeowners think are noises coming from their furnace are actually coming from their ductwork. Air pressure issues or loose ductwork can lead to ratting, banging, and other unpleasant sounds.
Dirty furnace burner
If your furnace’s burner or pilot light is dirty, it could be causing a delayed ignition, which can sound like a boom or bang every time your heating system cycles on.
The blower wheel is out of alignment
There are a lot of moving parts in your furnace, and sometimes even a slight shift in position can lead them to scrape or rub against other parts. It’s not uncommon that this can happen to your blower wheel, and it will need to be re-aligned to start functioning properly again.
Clogged furnace air filter
The air filter in your system removes dust and other particulates from the air circulating through your home, improving indoor air quality and helping your system run smoothly. But if you forget to replace your dirty filter with a new one every few months, air can have a tough time getting through and create a screeching sound in your home.
Are There Any Other Symptoms?
Loud noises from your furnace can be more than just an annoyance—they might signal a deeper issue. If these noises are accompanied by symptoms like uneven heating, weak airflow, frequent cycling, or unusual odors, your furnace could be struggling with a mechanical problem or nearing the end of its lifespan. Ignoring these signs can lead to more significant repairs or even a complete system failure. Don’t wait for the issue to worsen—call the experts at Princeton Air.
