3 Ways to Make Your Furnace Heat More Quietly

November 09, 2020

As your furnace turns on and begins to heat your house, it’s expected for it to produce some noise. These sounds, like the burners firing up and the blower whirring, are all part of the typical start-up steps.

But there are a couple of steps you can do to make your furnace less noisy this winter.

1. Schedule Yearly Furnace Maintenance

Furnace maintenance is extremely important, since it keeps your manufacturer warranty valid. This helps shield you if something major malfunctions in your furnace during your warranty time.

It can also help our pros find minor issues that might make your furnace annoying. And maybe help you prevent a meltdown on the most frigid day of the year. The Indoor Air Quality Association reports that annual maintenance can reduce your chance of furnace meltdowns by up to 95%.

If minor furnace troubles go undetected, they may lead to a breakdown later on. By unearthing these problems sooner, our professionals can get your furnace repaired before heating season is underway.

And, most essential, professional cleaning and lubrication of your furnace’s moving parts can help make it more efficient. A correctly maintained furnace could save up to 30% on your energy expenses, according to the U.S. Department of Energy.

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

Your air filter helps keep your home’s air fresh and clean. When it turns too dirty, it can make your furnace turn on and off more than it should. Called short cycling, this can cause your furnace to consume extra energy and make it wear out more rapidly.

Our suggestions for changing 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. Get in Touch with Walter's-Eaton's Electric, Plumbing, Heating & AC When Your Furnace is Creating Strange Noises

Some furnaces, especially older ones, can make more noise than others. But if you’re hearing very loud or weird noises, you might need to contact a heating and cooling company like Walter's-Eaton's Electric, Plumbing, Heating & AC for furnace repair in Ellsworth.

Here are a few noises to be looking for, how to solve them and when to call a specialist.

Furnace Making Gurgling or Bubbling Noise

This noise happens more frequently with high-efficiency furnaces. That’s due to the fact they exhaust fumes in another way than older furnaces, and the process can make some moisture. If your furnace is having difficulties discharging this water, it can make gurgling or bubbling sounds. You’ll require pro help for this problem, since it may be caused by a blocked drain pipe or clogged drain pan.

Furnace Making Banging Noise

It’s not a great thing when your furnace is making a banging sound. It may mean a couple of things.

Haven’t scheduled maintenance this year and your furnace is producing a banging sound when turning on? Its burners can be dirty. Dirty burners can hold up ignition, which causes gas to accumulate inside your furnace.

All that increased gas can create a banging or booming sound when your furnace ultimately does ignite. But this is more than just a bothersome noise, since the accumulated gas is exploding within your furnace. This can break your furnace’s heat exchanger and create a life-threatening carbon monoxide leak.

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

We advise first looking at your furnace’s air filter and installing a new one if it’s dirty. Next, make sure you don’t have too many vents sealed in your residence, as it can make air pressure uneven.

If neither of these methods fix the issue, your ductwork may be dirty or undersized, which will be a need for assistance from a skilled HVAC tech.

Furnace Making Humming or Buzzing Noise

If your furnace is buzzing or humming, it’s a symptom there’s an electrical problem. This is most usually seen with a faltering blower fan motor, which will create an annoying buzzing noise when your furnace starts. It could also mean there’s trouble with the capacitor or transformer. All three of these issues call for help from an experienced heating and cooling company like Walter's-Eaton's Electric, Plumbing, Heating & AC.

Furnace Making Knocking Noise

If your furnace is making knocking sounds, it’s frequently an indication that an internal part is breaking down. This can be anything from a bearing to a belt or the gas valve. It may also be a sign that your burners need cleaning.

These issues are typically caught during regular maintenance provided by a certified HVAC pro. So, while we’re at your house doing repairs, don’t forget to inquire about scheduling your maintenance appointment for the upcoming year.

Furnace Making Clicking Noise

A clicking sound can be created by things: worn bearings, gas valve issues or ignition issues. All these troubles require pro assistance.
