3 Ways to Make Your Furnace Heat More Quietly

November 09, 2020

As your furnace switches on and prepares to heat your house, it’s normal for it to produce some noise. These sounds, such as the burners lighting and the blower running, are all part of the usual start-up steps.

But there are a few things you can do to make your furnace run more quietly this winter.

1. Schedule Regular Furnace Maintenance

Furnace maintenance is highly important, as 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 discover small problems that might make your furnace noisy. And possibly help you avoid a meltdown on the chilliest day of the year. The Indoor Air Quality Association reports that regular maintenance can lower your chance of furnace breakdowns by up to 95%.

If minor furnace problems keep on being unnoticed, they may lead to trouble in the future. By finding these problems in advance, our techs can get your furnace fixed before heating season is in full swing.

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

2. Regularly Install a New Furnace’s Air Filter

Your air filter helps keep your house’s air fresh and clean. When it turns too clogged, it can make your furnace turn on and off too often. Referred to as short cycling, this can cause your furnace to consume more fuel and make it stop working more quickly.

Our recommendations for installing a new 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 Honke Heating & AC When Your Furnace is Making Weird Noises

Some furnaces, particularly older ones, could be louder than others. But if you’re detecting very loud or strange noises, you should get in touch with a heating and cooling company like Honke Heating & AC for furnace repair in Gresham.

Here are a few noises to be looking for, how to fix them and when to contact a professional.

Furnace Making Gurgling or Bubbling Noise

This noise is more common with high-efficiency furnaces. That’s since they emit fumes differently than older furnaces, and the process can create some moisture. If your furnace is having issues discharging this water, it could make gurgling or bubbling sounds. You’ll require skilled support for this problem, since it might be the result of 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 might mean a couple of things.

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

All that built-up gas can create a banging or booming noise when your furnace eventually does ignite. But this is more than merely an annoying noise, as the accumulated gas is erupting in your furnace. This can break your furnace’s heat exchanger and cause a dangerous carbon monoxide leak.

If you’ve neglected regular maintenance for your furnace and you’re hearing this noise, give Honke Heating & AC a ring at 503-663-8033. Our heating specialists will get your furnace tuned up and ensure it’s working properly.

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

We advise first inspecting your furnace’s air filter and installing a new one if it’s clogged. Next, double-check you don’t have too many vents closed in your home, as it can force air pressure out of balance.

If neither of these things repair the issue, your ductwork might 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 sign there’s electrical troubles. This is most usually seen with a sputtering blower fan motor, which will create an irritating buzzing noise when your furnace turns on. It can also mean there’s a problem with the capacitor or transformer. All three of these troubles require assistance from a skilled heating and cooling company like Honke Heating & AC.

Furnace Making Knocking Noise

If your furnace is making knocking sounds, it’s typically a symptom that an internal piece is worn out. This could be anything from a bearing to a belt or the gas valve. It might also be an indication that your burners need cleaning.

These troubles are usually unearthed during yearly maintenance done by a certified HVAC professional. So, while we’re at your home doing repairs, don’t forget to inquire about requesting your maintenance appointment for the future.

Furnace Making Clicking Noise

A clicking sound might mean a couple of problems: worn bearings, gas valve troubles or ignition issues. All these issues call for professional help.
