3 Ways to Make Your Furnace Work Less Noisily

November 09, 2020

As your furnace starts up and gets ready to heat your house, it’s common for it to produce some noise. These sounds, such as the burners lighting and the blower operating, are all part of the typical start-up process.

But there are several steps you can do to make your furnace run more quietly this winter.

1. Book Annual Furnace Maintenance

Furnace maintenance is very important, since it keeps your manufacturer warranty valid. This helps shield you if something huge goes wrong with your furnace during your warranty range.

It can also help our professionals find minor problems that might make your furnace noisy. And possibly help you sidestep a breakdown on the most frigid day of the year. The Indoor Air Quality Association reports that routine maintenance can lower your likelihood of furnace meltdowns by up to 95%.

If little furnace troubles are left undetected, they might cause a breakdown in the future. By finding these troubles sooner, our technicians can get your furnace repaired before heating season is underway.

And, most critical, pro 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 heating expenses, according to the U.S. Department of Energy.

2. Frequently Install a New Furnace’s Air Filter

Your air filter helps keep your house’s air fresh and clean. When it gets too clogged, it can make your furnace turn on and off too often. Referred to as short cycling, this can cause your furnace to eat up more energy and make it stop working faster.

Our suggestions for replacing your furnace filter:

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

You might have to change your filter more often if you have allergies or pets.

3. Contact Hopper Heating and Air When Your Furnace is Creating Weird Noises

Some furnaces, particularly older ones, could be noisier than others. But if you’re hearing exceedingly loud or strange noises, you might need to contact a heating and cooling company like Hopper Heating and Air for furnace repair in Shelby.

Here are a couple of noises to be looking for, how to fix them and when to call a pro.

Furnace Making Gurgling or Bubbling Noise

This noise occurs more commonly 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 troubles draining this water, it may make gurgling or bubbling sounds. You’ll want experienced support for this trouble, since it can be caused 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 lately and your furnace is producing a banging sound when beginning? Its burners might be dirty. Dirty burners can delay ignition, which results in gas accumulating in your furnace.

All that increased gas can create a banging or booming racket when your furnace ultimately does ignite. But this is more than merely an annoying noise, as the increased gas is exploding within your furnace. This can damage your furnace’s heat exchanger and make a deadly carbon monoxide leak.

If you’ve forgotten regular tune-ups for your furnace and you’re hearing this noise, give Hopper Heating and Air a call at 704-233-7363. Our heating specialists will get your furnace tuned up and double-check it’s working accurately.

Your ductwork can also produce banging sounds when your furnace starts, because the metal is expanding and contracting.

We advise first inspecting your furnace’s air filter and installing a new one if it’s dirty. Next, ensure you don’t have too many vents sealed in your house, as it can throw off air pressure.

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

Furnace Making Humming or Buzzing Noise

If your furnace is buzzing or humming, it’s a flag there’s an electrical issue. This is most frequently seen with a sputtering blower fan motor, which will make an irritating buzzing noise when your furnace switches on. It can also mean there’s a problem with the capacitor or transformer. All three of these issues require help from a professional heating and cooling company like Hopper Heating and Air.

Furnace Making Knocking Noise

If your furnace is making knocking sounds, it’s frequently a symptom that an internal component is going out. This could be anything from a bearing to a belt or the gas valve. It may also be an indication that your burners are dirty.

These problems are usually caught during annual maintenance provided by a certified HVAC technician. So, while we’re at your residence working on repairs, don’t forget to check with us about requesting your maintenance appointment for next year.

Furnace Making Clicking Noise

A clicking sound could be the result of troubles: worn bearings, gas valve issues or ignition troubles. All these issues call for specialized support.

At Hopper Heating and Air, our experts are here to help you enjoy peaceful, energy-efficient comfort. If your furnace is louder than it typically is or creating strange sounds, contact us at 704-233-7363 to book an appointment right away.
