Make Your Furnace Operate More Quietly with These 3 Things

November 09, 2020

As your furnace starts up and begins to add warmth to your residence, it’s typical for it to produce some noise. These sounds, such as the burners lighting and the blower whirring, are all part of the typical start-up steps.

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

1. Schedule Annual Furnace Maintenance

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

It can also help our professionals spot small issues that could make your furnace noisy. And maybe help you sidestep a malfunction on the chilliest 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 problems go unnoticed, they could cause trouble in the future. By finding these issues in advance, our technicians can get your furnace taken care of before heating season is at its peak.

And, most critical, professional 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 heating bills, according to the U.S. Department of Energy.

2. Regularly Change Your Furnace’s Air Filter

Your air filter helps keep your house’s air fresh and clean. When it turns too filthy, it can make your furnace turn on and off more than it should. Known as short cycling, this can cause your furnace to eat up extra energy and make it stop working more quickly.

Our recommendations for changing your furnace filter:

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

You could have to change your filter more regularly if you have allergies or pets.

Here are a couple of noises to be on the lookout for, how to fix them and when to call a specialist.

Furnace Making Gurgling or Bubbling Noise

This noise occurs more commonly with high-efficiency furnaces. That’s because they emit fumes dissimilarly older furnaces, and the process can produce some moisture. If your furnace is experiencing issues draining this water, it may make gurgling or bubbling sounds. You’ll require pro assistance for this trouble, 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 may mean several things.

Haven’t scheduled maintenance lately and your furnace is making a banging sound when beginning? Its burners can be dirty. Dirty burners can hold up ignition, which results in gas accumulating within your furnace.

All that accumulated gas can create a banging or booming sound when your furnace eventually does ignite. But this is more than just an annoying noise, as the increased gas is igniting inside your furnace. This can break your furnace’s heat exchanger and create a dangerous carbon monoxide leak.

If you’ve neglected annual service for your furnace and you’re detecting this noise, give Home Comfort Heating & Air a ring at 763-276-0617. Our heating pros will get your furnace tuned up and make sure it’s running safely.

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

We advise first inspecting your furnace’s air filter and replacing it if it’s dirty. Next, double-check you don’t have too many vents closed in your house, as it can make air pressure uneven.

If neither of these methods repair the sound, your ductwork may be dirty or undersized, which will require assistance from a skilled HVAC technician.

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 faltering blower fan motor, which will create an annoying buzzing noise when your furnace begins to heat. It can also mean there’s an issue with the capacitor or transformer. All three of these troubles need support from a professional heating and cooling company like Home Comfort Heating & Air.
