3 Methods to Make Your Furnace Less Noisy

November 09, 2020

As your furnace switches on and gets ready to heat your house, it’s common for it to produce some noise. These sounds, like the burners igniting and the blower operating, are all part of the usual start-up procedures.

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

1. Schedule Annual Furnace Maintenance

Furnace maintenance is very important, as it keeps your manufacturer warranty ongoing. This helps defend you if something big stops working in your furnace during your warranty time.

It can also help our pros uncover little issues that can make your furnace loud. And possibly help you sidestep a breakdown on the chilliest day of the year. The Indoor Air Quality Association reports that routine maintenance can decrease your likelihood of furnace breakdowns by up to 95%.

If little furnace troubles are left undetected, they can result in a breakdown in the future. By uncovering these problems sooner, our techs can get your furnace fixed before heating season begins.

And, most critical, professional cleaning and lubrication of your furnace’s moving components can help make it more efficient. A correctly maintained furnace could save up to 30% on your gas expenses, 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 turns too filthy, it can make your furnace turn on and off more than it should. Called short cycling, this can cause your furnace to use more energy and make it break down more rapidly.

Our advice for replacing your furnace filter:

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

You may have to get a new filter more frequently if you have allergies or pets.

3. Call Rescue Heating & Air When Your Furnace is Creating Weird Noises

Some furnaces, often older ones, can be noisier than others. But if you’re detecting exceedingly loud or strange noises, you might need to get in touch with a heating and cooling company like Rescue Heating & Air for furnace repair in Alice.

Here are a couple of noises to keep an eye out for, how to repair them and when to call a pro.

Furnace Making Gurgling or Bubbling Noise

This noise is more common with high-efficiency furnaces. That’s due to the fact they discharge fumes differently than older furnaces, and the process can make some moisture. If your furnace is experiencing troubles draining this water, it may make gurgling or bubbling sounds. You’ll require skilled assistance for this problem, since it may be caused by a blocked drain pipe or clogged drain pan.

Furnace Making Banging Noise

It’s not a positive thing 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 turning on? Its burners could be dirty. Dirty burners can hold up ignition, which causes gas to accumulate in your furnace.

All that increased gas can make a banging or booming sound when your furnace finally does ignite. But this is more than only an annoying noise, because the built-up gas is erupting in your furnace. This can break your furnace’s heat exchanger and make a deadly carbon monoxide leak.

If you’ve ignored regular service for your furnace and you’re detecting this noise, give Rescue Heating & Air a shout at 361-265-4371. Our heating pros will get your furnace tuned up and make sure it’s working properly.

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

We recommend first checking your furnace’s air filter and replacing it if it’s filthy. Next, ensure you don’t have too many vents shut in your home, as it can make air pressure uneven.

If neither of these steps fix the sound, your ductwork may be dirty or undersized, which will call for assistance from a professional HVAC technician.

Furnace Making Humming or Buzzing Noise

If your furnace is buzzing or humming, it’s a symptom there’s electrical troubles. This is most often seen with a dying blower fan motor, which will make a loud buzzing noise when your furnace starts. It may also mean there’s a problem with the capacitor or transformer. All three of these issues call for support from a skilled heating and cooling company like Rescue Heating & Air .

Furnace Making Knocking Noise

If your furnace is making knocking sounds, it’s typically a symptom that an internal component is worn out. This can be anything from a bearing to a belt or the gas valve. It may also be a sign that your burners are dirty.

These problems are frequently caught during regular maintenance performed by a certified HVAC pro. So, while we’re at your home working on repairs, don’t forget to ask us about requesting your maintenance appointment for the future.

Furnace Making Clicking Noise

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