As your furnace starts up and gets ready to add warmth to your home, it’s typical for it to produce some noise. These sounds, such as the burners igniting and the blower whirring, are all part of the normal start-up steps.

But there are a few approaches you can do to make your furnace quieter this winter.

1. Book Regular Furnace Maintenance

Furnace maintenance is highly important, as it keeps your manufacturer warranty in place. This helps shield you if something major stops working in your furnace during your warranty period.

It can also help us spot minor issues that can make your furnace annoying. And possibly help you sidestep a meltdown on the coldest day of the year. The Indoor Air Quality Association reports that regular maintenance can decrease your likelihood of furnace meltdowns by up to 95%.

If little furnace troubles go unnoticed, they may cause trouble down the road. By unearthing these troubles sooner, our professionals can get your furnace fixed before heating season is underway.

And most important, specialized cleaning and lubrication of your furnace’s moving pieces can help make it more efficient. A well-maintained furnace could save up to 30% on your gas bills, according to the U.S. Department of Energy.

2. Frequently Put in a New Furnace’s Air Filter

Your air filter helps keep your house’s air fresh and clean. When it becomes too filthy, it can make your furnace turn on and off too often. Referred to as short cycling, this can cause your furnace to use additional fuel and make it break down faster.

Our advice for installing a new furnace filter:

  • Flat filter: Once a month
  • Pleated filter: Every three months

You may have to replace your filter more frequently if you have allergies or pets.

3. Get in Touch with Pliescott HVAC Services LLC When Your Furnace Is Creating Strange Noises

Some furnaces, particularly older ones, might be noisier than others. But if you’re detecting very loud or strange noises, you might need to get in touch with a heating and cooling company like Pliescott HVAC Services LLC for furnace repair in Cambridge.

Here are several noises to be looking for, how to solve them and when to get in touch with a pro.

Furnace Making Gurgling or Bubbling Noise

This noise happens more frequently with high-efficiency furnaces. That’s because they emit fumes differently than older furnaces, and the process can make some moisture. If your furnace is running into difficulties removing this water, it could make gurgling or bubbling sounds. You’ll want skilled support for this trouble, since it may be created by a blocked drain pipe or clogged drain pan.

Furnace Making Banging Noise

It’s not a positive thing when your furnace is making a banging sound. It can mean several things.

Haven’t scheduled maintenance recently and your furnace is creating a banging sound when starting? Its burners could be dirty. Dirty burners can stall ignition, which causes gas to accumulate inside your furnace.

All that increased gas can cause a banging or booming racket when your furnace eventually does ignite. But this is more than merely an irritating noise, as the built-up gas is exploding within your furnace. This can crack your furnace’s heat exchanger and cause a dangerous carbon monoxide leak.

If you’ve forgotten regular maintenance for your furnace and you’re noticing this noise, give Pliescott HVAC Services LLC a ring at 410-228-4822. Our heating pros will get your furnace tuned up and double-check it’s working correctly.

Your ductwork can also make banging sounds when your furnace turns on, as the metal is expanding and contracting.

We recommend first checking your furnace’s air filter and replacing it if it’s dirty. Next, make sure you don’t have too many vents closed in your home, as it can force air pressure out of balance.

If neither of these steps repair the sound, your ductwork could be dirty or undersized, which will call for assistance from a skilled HVAC specialist.

Furnace Making Humming or Buzzing Noise

If your furnace is buzzing or humming, it’s a flag there’s electrical troubles. This is most usually seen with a faltering blower fan motor, which will produce an irritating buzzing noise when your furnace begins to heat. It may also mean there’s a problem with the capacitor or transformer. All three of these issues need help from a professional heating and cooling company like Pliescott HVAC Services LLC.

Furnace Making Knocking Noise

If your furnace is making knocking sounds, it’s usually a symptom that an internal piece is going out. This may be anything from a bearing to a belt or the gas valve. It might also be a sign that your burners need to be cleaned.

These problems are usually uncovered during regular maintenance done by a certified HVAC professional. So, while we’re at your house performing repairs, don’t forget to check with us about scheduling your maintenance appointment for the future.

Furnace Making Clicking Noise

A clicking sound might be the result of issues: worn bearings, gas valve problems or ignition troubles. All these troubles need professional help.
