As your furnace switches on and gets ready to add warmth to your residence, it’s expected for it to produce some noise. These sounds, like the burners igniting and the blower running, are all part of the normal start-up steps.

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

1. Schedule Yearly Furnace Maintenance

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

It can also help us spot small issues that might make your furnace noisy. And potentially help you avoid a breakdown on the most frigid day of the year. The Indoor Air Quality Association reports that routine maintenance can lower your probability of furnace malfunctions by up to 95%.

If little furnace problems go unnoticed, they may cause trouble in the future. By finding these problems sooner, our pros can get your furnace repaired before heating season begins.

And most important, specialized 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 gas bills, according to the U.S. Department of Energy.

2. Frequently Replace Your Furnace’s Air Filter

Your air filter helps keep your residence’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 consume additional fuel and make it break down faster.

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 often if you have allergies or pets.

3. Get in Touch with Central Air LLC When Your Furnace Is Making Odd Noises

Some furnaces, especially older ones, can be noisier than others. But if you’re noticing extremely loud or odd noises, it may be time to contact a heating and cooling company like Central Air LLC for furnace repair in Brookfield.

Here are several noises to keep an eye out for, how to solve them and when to call a professional.

Furnace Making Gurgling or Bubbling Noise

This noise happens more frequently 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 experiencing difficulties draining this water, it can make gurgling or bubbling sounds. You’ll need pro support 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 great thing when your furnace is making a banging sound. It can mean several things.

Haven’t scheduled maintenance recently and your furnace is creating a banging sound when starting? Its burners may be dirty. Dirty burners can hold up ignition, which results in gas accumulating in your furnace.

All that built-up gas can make a banging or booming sound when your furnace finally does ignite. But this is more than just an irritating noise, as the built-up gas is exploding within your furnace. This can crack your furnace’s heat exchanger and cause a life-threatening carbon monoxide leak.

If you’ve ignored regular tune-ups for your furnace and you’re noticing this noise, give Central Air LLC a ring at 203-357-5913. Our heating professionals will get your furnace tuned up and double-check it’s operating correctly.

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

We advise first checking your furnace’s air filter and installing a new one if it’s filthy. Next, make sure you don’t have too many vents sealed in your house, as it can throw off air pressure.

If neither of these steps repair the problem, your ductwork might be dirty or undersized, which will call for assistance from a pro HVAC tech.

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 dying blower fan motor, which will create an irritating buzzing noise when your furnace starts. It could 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 Central Air LLC.

Furnace Making Knocking Noise

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

These troubles are often uncovered during yearly maintenance performed by a certified HVAC tech. So, while we’re at your house performing repairs, don’t forget to inquire about booking your maintenance appointment for the future.

Furnace Making Clicking Noise

A clicking sound might be the result of troubles: worn bearings, gas valve troubles or ignition troubles. All these troubles need skilled assistance.
