3 Ways to Make Your Furnace Work Less Noisily

November 09, 2020

As your furnace turns on and begins to add warmth to your home, it’s common for it to make some noise. These sounds, including the burners lighting and the blower operating, are all part of the typical start-up process.

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

1. Book Annual Furnace Maintenance

Furnace maintenance is very important, as it keeps your manufacturer warranty in place. This helps protect you if something big goes wrong with your furnace during your warranty time.

It can also help us find small issues that can make your furnace loud. And potentially help you avoid a malfunction on the coldest day of the year. The Indoor Air Quality Association reports that regular maintenance can lower your chance of furnace repairs by up to 95%.

If little furnace troubles are left undetected, they can cause a breakdown in the future. By uncovering these issues in advance, our technicians can get your furnace fixed before heating season is in full swing.

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

2. Routinely Install a New Furnace’s Air Filter

Your air filter helps keep your home’s air fresh and clean. When it turns too dirty, it can make your furnace turn on and off more than it should. Referred to as short cycling, this can cause your furnace to use more fuel and make it stop working more rapidly.

Our suggestions for installing a new furnace filter:

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

You may have to replace your filter more regularly if you have allergies or pets.

3. Get in Touch with Dial One Mears Air Conditioning & Heating Inc When Your Furnace is Making Strange Noises

Some furnaces, particularly older ones, might be louder than others. But if you’re noticing exceedingly loud or weird noises, it may be time to call a heating and cooling company like Dial One Mears Air Conditioning & Heating Inc for furnace repair in Phoenix.

Here are a few noises to be on the lookout for, how to solve them and when to contact a pro.

Furnace Making Gurgling or Bubbling Noise

This noise happens more frequently with high-efficiency furnaces. That’s since they exhaust fumes in another way than older furnaces, and the process can produce some moisture. If your furnace is running into issues removing this water, it can make gurgling or bubbling sounds. You’ll require pro assistance for this issue, since it can be created 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 may mean a few things.

Haven’t had maintenance done this year and your furnace is producing a banging sound when starting? Its burners might be dirty. Dirty burners can stall ignition, which causes gas to accumulate within your furnace.

All that built-up gas can cause a banging or booming sound when your furnace eventually does ignite. But this is more than just an irritating noise, since the accumulated gas is erupting in your furnace. This can break your furnace’s heat exchanger and make a deadly carbon monoxide leak.

If you’ve overlooked regular service for your furnace and you’re detecting this noise, give Dial One Mears Air Conditioning & Heating Inc a shout at 602-832-7808. Our heating pros will get your furnace tuned up and ensure it’s working accurately.

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

We suggest first looking at your furnace’s air filter and getting a new one if it’s clogged. Next, double-check you don’t have too many vents shut in your residence, as it can throw off air pressure.

If neither of these methods repair the issue, your ductwork may be dirty or undersized, which will call for assistance from a pro HVAC specialist.

Furnace Making Humming or Buzzing Noise

If your furnace is buzzing or humming, it’s a flag there’s an electrical issue. This is most usually seen with a faltering blower fan motor, which will create an annoying buzzing noise when your furnace starts. It may also mean there’s a problem with the capacitor or transformer. All three of these issues need assistance from an experienced heating and cooling company like Dial One Mears Air Conditioning & Heating Inc.

Furnace Making Knocking Noise

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

These problems are frequently caught during regular maintenance done by a certified HVAC technician. So, while we’re at your residence working on repairs, don’t forget to inquire about requesting your maintenance appointment for next year.

Furnace Making Clicking Noise

A clicking sound could mean a couple of things: worn bearings, gas valve issues or ignition issues. All these problems require specialized support.
