3 Ways to Make Your Furnace Work Less Noisily

As your furnace turns on and gets ready to heat your residence, it’s normal for it to produce some noise. These sounds, including the burners lighting and the blower running, are all part of the normal start-up steps.

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

1. Schedule Regular Furnace Maintenance

Furnace maintenance is highly important, since it keeps your manufacturer warranty valid. This helps shield you if something huge stops working in your furnace during your warranty time.

It can also help our professionals find small troubles that could make your furnace loud. And potentially help you prevent a meltdown on the chilliest day of the year. The Indoor Air Quality Association reports that annual maintenance can reduce your likelihood of furnace breakdowns by up to 95%.

If little furnace troubles keep on being unnoticed, they may cause a breakdown later on. By discovering these problems sooner, our technicians can get your furnace taken care of before heating season is at its peak.

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 utility bills, according to the U.S. Department of Energy.

2. Routinely 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 more than it should. Called short cycling, this can cause your furnace to consume extra gas and make it stop working more quickly.

Our advice for replacing your furnace filter:

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

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

3. Call Northern Comfort Inc When Your Furnace is Making Odd Noises

Some furnaces, particularly older ones, can make more noise than others. But if you’re detecting exceedingly loud or weird noises, you might need to call a heating and cooling company like Northern Comfort Inc for furnace repair in Mankato area.

Here are a couple of noises to be on the lookout for, how to repair them and when to get in touch with a pro.

Furnace Making Gurgling or Bubbling Noise

This noise occurs more commonly with high-efficiency furnaces. That’s because 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 may make gurgling or bubbling sounds. You’ll need skilled support for this trouble, since it could be caused 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 requested maintenance this year and your furnace is making a banging sound when starting? Its burners may be dirty. Dirty burners can delay ignition, which results in gas accumulating inside your furnace.

All that accumulated gas can cause a banging or booming noise when your furnace eventually does ignite. But this is more than just a bothersome noise, because the built-up gas is exploding inside your furnace. This can crack your furnace’s heat exchanger and make a dangerous carbon monoxide leak.

If you’ve forgotten regular maintenance for your furnace and you’re hearing this noise, give Northern Comfort Inc a call at 507-387-6596. Our heating professionals will get your furnace tuned up and make sure it’s running accurately.

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

We suggest first inspecting your furnace’s air filter and getting a new one if it’s filthy. Next, double-check you don’t have too many vents sealed in your home, as it can make air pressure uneven.

If neither of these things repair the sound, your ductwork could 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 annoying buzzing noise when your furnace turns on. It can also mean there’s an issue with the capacitor or transformer. All three of these issues need assistance from a skilled heating and cooling company like Northern Comfort Inc.

Furnace Making Knocking Noise

If your furnace is making knocking sounds, it’s often a sign that an internal component is breaking down. This can be anything from a bearing to a belt or the gas valve. It might also be a sign that your burners need to be cleaned.

These troubles are frequently unearthed during annual maintenance performed by a certified HVAC pro. So, while we’re at your house doing repairs, don’t forget to check with us about scheduling your maintenance appointment for next year.

Furnace Making Clicking Noise

A clicking sound can mean a couple of troubles: worn bearings, gas valve issues or ignition issues. All these problems need specialized support.
