3 Steps to Make Your Furnace Less Noisy

November 09, 2020

As your furnace starts up and begins to warm up your residence, it’s expected for it to create some noise. These sounds, such as the burners igniting and the blower running, are all part of the typical start-up steps.

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

1. Schedule Regular Furnace Maintenance

Furnace maintenance is very important, because it keeps your manufacturer warranty ongoing. This helps protect you if something major malfunctions in your furnace during your warranty time.

It can also help our pros uncover small issues that can make your furnace annoying. And potentially help you avoid a meltdown on the chilliest day of the year. The Indoor Air Quality Association reports that regular maintenance can decrease your probability of furnace malfunctions by up to 95%.

If little furnace issues go undetected, they can result in a malfunction later on. By unearthing these troubles early, our techs can get your furnace fixed before heating season is underway.

And, most essential, pro cleaning and lubrication of your furnace’s moving components 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. Frequently Install a New Furnace’s Air Filter

Your air filter helps keep your residence’s air fresh and clean. When it becomes too filthy, it can make your furnace turn on and off too often. Called short cycling, this can cause your furnace to use more gas and make it stop working more quickly.

Our advice for installing a new furnace filter:

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

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

3. Contact WM J Kraus & Son When Your Furnace is Producing Weird Noises

Some furnaces, particularly older ones, can make more noise than others. But if you’re hearing extremely loud or weird noises, you might need to contact a heating and cooling company like WM J Kraus & Son for furnace repair in Keokuk.

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

Furnace Making Gurgling or Bubbling Noise

This noise occurs more commonly with high-efficiency furnaces. That’s since they exhaust fumes in another way than older furnaces, and the process can create some moisture. If your furnace is having issues draining this water, it can make gurgling or bubbling sounds. You’ll require professional help for this trouble, since it might be created 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 might mean a couple of things.

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

All that increased gas can make a banging or booming noise when your furnace eventually does ignite. But this is more than only a bothersome noise, as the accumulated gas is igniting inside your furnace. This can damage your furnace’s heat exchanger and cause a dangerous carbon monoxide leak.

If you’ve overlooked yearly maintenance for your furnace and you’re hearing this noise, give WM J Kraus & Son a ring at 319-229-2318. Our heating professionals will get your furnace tuned up and double-check it’s running accurately.

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

We recommend first looking at 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 residence, as it can make air pressure uneven.

If neither of these methods fix the issue, your ductwork might be dirty or undersized, which will require assistance from a professional 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 sputtering blower fan motor, which will create an annoying buzzing noise when your furnace turns on. It might also mean there’s trouble with the capacitor or transformer. All three of these problems require assistance from a skilled heating and cooling company like WM J Kraus & Son.

Furnace Making Knocking Noise

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

These issues are frequently caught during annual maintenance done by a certified HVAC pro. So, while we’re at your residence performing repairs, don’t forget to ask us 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 issues or ignition problems. All these issues require skilled assistance.
