3 Ways to Make Your Furnace Run More Quietly

November 09, 2020

As your furnace switches on and prepares to warm up your home, it’s normal for it to create some noise. These sounds, like the burners firing up and the blower operating, are all part of the usual start-up procedures.

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

1. Book Regular Furnace Maintenance

Furnace maintenance is highly important, as it keeps your manufacturer warranty ongoing. This helps protect you if something huge malfunctions in your furnace during your warranty time.

It can also help us uncover small troubles that might make your furnace noisy. And possibly help you prevent a malfunction on the most frigid day of the year. The Indoor Air Quality Association reports that annual maintenance can lower your probability of furnace malfunctions by up to 95%.

If small furnace issues go undetected, they could lead to trouble later on. By discovering these problems sooner, our techs can get your furnace taken care of before heating season begins.

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

2. Regularly Replace Your Furnace’s Air Filter

Your air filter helps keep your residence’s air fresh and clean. When it becomes too dirty, it can make your furnace turn on and off too often. Referred to as short cycling, this can cause your furnace to eat up more fuel and make it wear out more quickly.

Our advice for replacing your furnace filter:

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

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

3. Contact Northglenn Heating & Air Conditioning, Inc. When Your Furnace is Producing Strange Noises

Some furnaces, often older ones, can be noisier than others. But if you’re noticing very loud or strange noises, it may be time to get in touch with a heating and cooling company like Northglenn Heating & Air Conditioning, Inc. for furnace repair in Northglenn.

Here are several noises to be looking for, how to solve them and when to contact a specialist.

Furnace Making Gurgling or Bubbling Noise

This noise is more common with high-efficiency furnaces. That’s since they emit fumes in another way than older furnaces, and the process can produce some moisture. If your furnace is experiencing issues draining this water, it could make gurgling or bubbling sounds. You’ll require pro support for this issue, since it could be created by a blocked drain pipe or clogged drain pan.

Furnace Making Banging Noise

It’s not a great sign when your furnace is making a banging sound. It may mean a couple of things.

Haven’t had maintenance done recently and your furnace is producing a banging sound when turning on? Its burners may be dirty. Dirty burners can delay ignition, which causes gas to accumulate in your furnace.

All that accumulated gas can make a banging or booming sound when your furnace ultimately does ignite. But this is more than merely a bothersome noise, since the increased gas is erupting within your furnace. This can break your furnace’s heat exchanger and make a deadly carbon monoxide leak.

If you’ve overlooked regular maintenance for your furnace and you’re hearing this noise, give Northglenn Heating & Air Conditioning, Inc. a call at 303-452-4146. Our heating professionals will get your furnace tuned up and ensure it’s working safely.

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

We suggest first inspecting your furnace’s air filter and installing a new one if it’s filthy. Next, make sure you don’t have too many vents shut in your residence, as it can force air pressure out of balance.

If neither of these things fix the sound, 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 flag there’s an electrical problem. This is most usually seen with a sputtering blower fan motor, which will create a loud buzzing noise when your furnace begins to heat. It might also mean there’s an issue with the capacitor or transformer. All three of these troubles need support from a skilled heating and cooling company like Northglenn Heating & Air Conditioning, Inc..

Furnace Making Knocking Noise

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

These problems are often uncovered during annual maintenance done by a certified HVAC pro. So, while we’re at your residence doing repairs, don’t forget to inquire about booking your maintenance appointment for the upcoming year.

Furnace Making Clicking Noise

A clicking sound could be the result of problems: worn bearings, gas valve troubles or ignition troubles. All these problems require specialized support.
