3 Ways to Make Your Furnace Run Less Noisily

November 09, 2020

As your furnace turns on and gets ready to add warmth to your residence, it’s expected for it to create some noise. These sounds, including the burners lighting and the blower operating, are all part of the usual start-up procedures.

But there are a couple of things you can do to make your furnace quieter this winter.

1. Book Yearly Furnace Maintenance

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

It can also help us spot minor issues that might make your furnace noisy. And possibly help you sidestep a breakdown on the chilliest 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 little furnace troubles go undetected, they can lead to trouble down the road. By unearthing these problems sooner, our professionals can get your furnace repaired before heating season begins.

And, most important, pro 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 gas expenses, according to the U.S. Department of Energy.

2. Frequently Replace Your 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 more than it should. Referred to as short cycling, this can cause your furnace to use additional gas and make it break down more quickly.

Our advice for replacing your furnace filter:

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

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

3. Contact American HVAC Inc When Your Furnace is Making Weird Noises

Some furnaces, often older ones, could be louder than others. But if you’re detecting very loud or strange noises, it may be time to contact a heating and cooling company like American HVAC Inc for furnace repair in Sacramento.

Here are a few noises to be looking for, how to repair them and when to call a specialist.

Furnace Making Gurgling or Bubbling Noise

This noise is more common with high-efficiency furnaces. That’s due to the fact they exhaust fumes in another way than older furnaces, and the process can create some moisture. If your furnace is running into issues draining this water, it can make gurgling or bubbling sounds. You’ll need pro support for this trouble, since it could be the result of by a blocked drain pipe or clogged drain pan.

Furnace Making Banging Noise

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

Haven’t scheduled maintenance recently and your furnace is making a banging sound when beginning? Its burners might be dirty. Dirty burners can hold up ignition, which leads gas to accumulate inside your furnace.

All that accumulated gas can create a banging or booming racket when your furnace ultimately does ignite. But this is more than only an irritating noise, since the accumulated gas is igniting in your furnace. This can break your furnace’s heat exchanger and make a deadly carbon monoxide leak.

If you’ve neglected yearly maintenance for your furnace and you’re hearing this noise, give American HVAC Inc a ring at 916-243-6714. Our heating professionals will get your furnace tuned up and make sure it’s working safely.

Your ductwork can also make 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 filthy. Next, ensure you don’t have too many vents shut in your home, as it can force air pressure out of balance.

If neither of these things take care of the problem, your ductwork may be dirty or undersized, which will call for assistance from a professional HVAC tech.

Furnace Making Humming or Buzzing Noise

If your furnace is buzzing or humming, it’s a sign there’s an electrical issue. This is most often seen with a sputtering blower fan motor, which will create an annoying buzzing noise when your furnace switches on. It can also mean there’s trouble with the capacitor or transformer. All three of these issues require help from a professional heating and cooling company like American HVAC Inc.

Furnace Making Knocking Noise

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

These problems are typically uncovered during regular maintenance done by a certified HVAC pro. So, while we’re at your house working on repairs, don’t forget to inquire about requesting your maintenance appointment for the future.

Furnace Making Clicking Noise

A clicking sound may be the result of troubles: worn bearings, gas valve issues or ignition troubles. All these problems call for pro assistance.
