Make Your Furnace Run More Quietly with These 3 Approaches

As your furnace switches on and prepares to add warmth to your house, it’s common for it to make some noise. These sounds, including the burners lighting and the blower whirring, are all part of the usual start-up process.

But there are several steps you can do to make your furnace quieter this winter.

1. Schedule Regular Furnace Maintenance

Furnace maintenance is very important, since it keeps your manufacturer warranty ongoing. This helps protect you if something big malfunctions in your furnace during your warranty time.

It can also help us spot minor issues that can make your furnace noisy. And maybe help you sidestep a meltdown on the coldest day of the year. The Indoor Air Quality Association reports that regular maintenance can reduce your chance of furnace repairs by up to 95%.

If minor furnace problems go undetected, they could cause trouble in the future. By uncovering these issues in advance, our techs can get your furnace fixed before heating season is at its peak.

And, most essential, 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. Routinely Change Your Furnace’s Air Filter

Your air filter helps keep your home’s air fresh and clean. When it becomes too filthy, it can make your furnace turn on and off too often. Known as short cycling, this can cause your furnace to consume additional fuel and make it wear out more quickly.

Our advice for installing a new furnace filter:

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

You might have to install a new filter more often if you have allergies or pets.

3. Call Climate Control Systems When Your Furnace is Creating Odd Noises

Some furnaces, particularly older ones, can make more noise than others. But if you’re noticing extremely loud or strange noises, you should get in touch with a heating and cooling company like Climate Control Systems for furnace repair in Hickory.

Here are several noises to be on the lookout for, how to fix them and when to call a pro.

Furnace Making Gurgling or Bubbling Noise

This noise is more common 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 having difficulties discharging this water, it can make gurgling or bubbling sounds. You’ll need skilled assistance for this trouble, since it may be the result of by a blocked drain pipe or clogged drain pan.

Furnace Making Banging Noise

It’s not a positive indicator when your furnace is making a banging sound. It could mean a couple of things.

Haven’t requested maintenance lately and your furnace is creating a banging sound when starting? Its burners could be dirty. Dirty burners can delay ignition, which results in gas accumulating inside your furnace.

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

If you’ve ignored annual service for your furnace and you’re hearing this noise, give Climate Control Systems a call at 828-283-0369. Our heating professionals will get your furnace tuned up and double-check it’s operating accurately.

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

We recommend first inspecting your furnace’s air filter and replacing it if it’s dirty. Next, double-check 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 issue, your ductwork could be dirty or undersized, which will be a need for assistance from a skilled HVAC specialist.

Furnace Making Humming or Buzzing Noise

If your furnace is buzzing or humming, it’s a symptom there’s electrical troubles. This is most often seen with a sputtering blower fan motor, which will make an annoying buzzing noise when your furnace begins to heat. It could also mean there’s a problem with the capacitor or transformer. All three of these issues need support from a skilled heating and cooling company like Climate Control Systems.

Furnace Making Knocking Noise

If your furnace is making knocking sounds, it’s usually a sign that an internal piece is dying. This could be anything from a bearing to a belt or the gas valve. It could also be a sign that your burners need cleaning.

These problems are frequently caught during regular maintenance provided by a certified HVAC professional. So, while we’re at your home performing 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 created by things: worn bearings, gas valve problems or ignition troubles. All these problems need specialized support.
