3 Ways to Make Your Furnace Run with Less Noise

November 09, 2020

As your furnace turns on and begins to heat your home, it’s typical for it to create some noise. These sounds, like the burners lighting and the blower running, are all part of the typical start-up procedures.

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

1. Book Regular Furnace Maintenance

Furnace maintenance is highly important, since it keeps your manufacturer warranty in place. This helps protect you if something huge goes wrong with your furnace during your warranty period.

It can also help our professionals spot small issues that can make your furnace noisy. And possibly help you sidestep a meltdown on the most frigid day of the year. The Indoor Air Quality Association reports that regular maintenance can lower your probability of furnace meltdowns by up to 95%.

If small furnace problems are left unnoticed, they may lead to a malfunction down the road. By discovering these problems in advance, our technicians can get your furnace fixed before heating season begins.

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

2. Routinely Install a New Furnace’s Air Filter

Your air filter helps keep your house’s air fresh and clean. When it gets too filthy, it can make your furnace turn on and off too frequently. Referred to as short cycling, this can cause your furnace to use extra gas and make it wear out faster.

Our suggestions for replacing your furnace filter:

  • Flat filter: Monthly
  • Pleated filter: Every three months

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

3. Call Kowalski Heating, Cooling & Plumbing When Your Furnace is Making Odd Noises

Some furnaces, often older ones, may make more noise than others. But if you’re noticing exceedingly loud or weird noises, it may be time to get in touch with a heating and cooling company like Kowalski Heating, Cooling & Plumbing for furnace repair in McMurray.

Here are a few noises to keep an eye out for, how to solve them and when to call a professional.

Furnace Making Gurgling or Bubbling Noise

This noise is more common with high-efficiency furnaces. That’s due to the fact they emit fumes in another way than older furnaces, and the process can make some moisture. If your furnace is experiencing difficulties removing this water, it can make gurgling or bubbling sounds. You’ll require experienced support 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 good thing when your furnace is making a banging sound. It could mean several things.

Haven’t had maintenance done recently and your furnace is making a banging sound when beginning? Its burners may be dirty. Dirty burners can stall ignition, which leads gas to accumulate within your furnace.

All that increased gas can make a banging or booming sound when your furnace ultimately does ignite. But this is more than only an annoying noise, as the accumulated gas is erupting within your furnace. This can crack your furnace’s heat exchanger and cause a dangerous carbon monoxide leak.

If you’ve forgotten yearly maintenance for your furnace and you’re noticing this noise, give Kowalski Heating, Cooling & Plumbing a call at 724-370-0141. Our heating pros will get your furnace tuned up and make sure it’s running properly.

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

We suggest first checking your furnace’s air filter and replacing it if it’s clogged. Next, ensure you don’t have too many vents sealed in your residence, as it can throw off air pressure.

If neither of these methods repair the issue, your ductwork could 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 flag there’s electrical troubles. This is most frequently seen with a dying blower fan motor, which will create an irritating buzzing noise when your furnace starts. It can 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 Kowalski Heating, Cooling & Plumbing.

Furnace Making Knocking Noise

If your furnace is making knocking sounds, it’s typically a symptom that an internal part is breaking down. This could be anything from a bearing to a belt or the gas valve. It could also be an indication that your burners need to be cleaned.

These problems are often caught during annual maintenance done by a certified HVAC technician. So, while we’re at your residence working on repairs, don’t forget to check with us about scheduling your maintenance appointment for the future.

Furnace Making Clicking Noise

A clicking sound can be the result of things: worn bearings, gas valve issues or ignition problems. All these troubles require pro help.
