3 Ways to Make Your Furnace Heat More Quietly

As your furnace switches on and prepares to heat your home, it’s normal for it to create some noise. These sounds, like the burners igniting and the blower running, are all part of the typical start-up steps.

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

1. Request Yearly Furnace Maintenance

Furnace maintenance is highly important, because it keeps your manufacturer warranty valid. This helps defend you if something major malfunctions in your furnace during your warranty range.

It can also help our professionals uncover small issues that can make your furnace loud. And potentially help you avoid a meltdown on the coldest day of the year. The Indoor Air Quality Association reports that routine maintenance can decrease your probability of furnace meltdowns by up to 95%.

If minor furnace troubles are left unnoticed, they may result in an issue down the road. By finding these issues sooner, our pros can get your furnace fixed before heating season is underway.

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

2. Regularly Change Your Furnace’s Air Filter

Your air filter helps keep your residence’s air fresh and clean. When it becomes too clogged, it can make your furnace turn on and off too often. Called short cycling, this can cause your furnace to use extra energy and make it wear out more quickly.

Our suggestions for changing your furnace filter:

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

You may have to get a new filter more frequently if you have allergies or pets.

3. Contact Banister's Heating & Air Conditioning Services When Your Furnace is Creating Strange Noises

Some furnaces, especially older ones, could be louder than others. But if you’re detecting very loud or strange noises, it may be time to get in touch with a heating and cooling company like Banister's Heating & Air Conditioning Services for furnace repair in Carlsbad.

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

Furnace Making Gurgling or Bubbling Noise

This noise happens more frequently with high-efficiency furnaces. That’s because they emit fumes in another way than older furnaces, and the process can create some moisture. If your furnace is running into difficulties removing this water, it may make gurgling or bubbling sounds. You’ll need pro assistance for this problem, since it could be created 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 could mean a couple of things.

Haven’t requested maintenance this year and your furnace is making a banging sound when beginning? Its burners can be dirty. Dirty burners can delay ignition, which leads gas to accumulate inside your furnace.

All that accumulated gas can make a banging or booming racket when your furnace ultimately does ignite. But this is more than just an annoying noise, since the built-up gas is exploding in your furnace. This can break your furnace’s heat exchanger and create a dangerous carbon monoxide leak.

If you’ve neglected regular maintenance for your furnace and you’re hearing this noise, give Banister's Heating & Air Conditioning Services a ring at 575-446-3948. Our heating professionals will get your furnace tuned up and make sure it’s running safely.

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

We recommend first checking your furnace’s air filter and replacing it if it’s dirty. Next, ensure you don’t have too many vents closed in your house, as it can throw off air pressure.

If neither of these steps fix the sound, your ductwork might be dirty or undersized, which will be a need for assistance from a pro HVAC tech.

Furnace Making Humming or Buzzing Noise

If your furnace is buzzing or humming, it’s a symptom there’s an electrical issue. This is most frequently seen with a faltering blower fan motor, which will create an irritating buzzing noise when your furnace begins to heat. It can also mean there’s a problem with the capacitor or transformer. All three of these issues need support from an experienced heating and cooling company like Banister's Heating & Air Conditioning Services.

Furnace Making Knocking Noise

If your furnace is making knocking sounds, it’s usually a symptom that an internal part is dying. 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 issues are frequently uncovered during regular maintenance done by a certified HVAC professional. So, while we’re at your home doing repairs, don’t forget to check with us about requesting your maintenance appointment for the future.

Furnace Making Clicking Noise

A clicking sound can be created by problems: worn bearings, gas valve problems or ignition problems. All these troubles need skilled assistance.
