Make Your Furnace Operate More Quietly with These 3 Steps

As your furnace starts up and begins to warm up your house, it’s expected for it to make some noise. These sounds, such as the burners firing up and the blower whirring, are all part of the usual start-up steps.

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

1. Request Regular Furnace Maintenance

Furnace maintenance is highly important, as it keeps your manufacturer warranty in place. This helps shield you if something major goes wrong with your furnace during your warranty time.

It can also help us spot little problems that could make your furnace loud. And possibly help you sidestep a breakdown on the coldest day of the year. The Indoor Air Quality Association reports that routine maintenance can decrease your probability of furnace breakdowns by up to 95%.

If little furnace troubles go ignored, they can cause a malfunction later on. By uncovering these issues early, our technicians can get your furnace fixed before heating season is in full swing.

And, most important, pro cleaning and lubrication of your furnace’s moving components can help make it more efficient. A properly 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 dirty, it can make your furnace turn on and off too often. Known as short cycling, this can cause your furnace to eat up extra gas and make it wear out faster.

Our recommendations for replacing your furnace filter:

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

You could have to change your filter more often if you have allergies or pets.

3. Call Scott Temperature When Your Furnace is Producing Strange Noises

Some furnaces, often older ones, may make more noise than others. But if you’re detecting exceedingly loud or weird noises, you should get in touch with a heating and cooling company like Scott Temperature for furnace repair in Lawrence.

Here are a few noises to be on the lookout 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 because they exhaust fumes differently than older furnaces, and the process can produce some moisture. If your furnace is having difficulties discharging this water, it can make gurgling or bubbling sounds. You’ll need skilled assistance for this issue, since it can be caused by a blocked drain pipe or clogged drain pan.

Furnace Making Banging Noise

It’s not a great sign when your furnace is making a banging sound. It can mean a few things.

Haven’t had maintenance done lately and your furnace is producing a banging sound when beginning? Its burners can be dirty. Dirty burners can hold up ignition, which causes gas to accumulate within your furnace.

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

If you’ve forgotten yearly service for your furnace and you’re noticing this noise, give Scott Temperature a shout at 785-269-0465. Our heating professionals will get your furnace tuned up and double-check it’s working accurately.

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

We recommend first looking at your furnace’s air filter and getting a new one if it’s clogged. Next, make sure you don’t have too many vents sealed in your residence, as it can force air pressure out of balance.

If neither of these methods fix the sound, your ductwork could be dirty or undersized, which will be a need 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 an electrical issue. This is most usually seen with a dying blower fan motor, which will make an annoying buzzing noise when your furnace switches on. It could 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 Scott Temperature.

Furnace Making Knocking Noise

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

These problems are typically unearthed during yearly maintenance performed by a certified HVAC professional. So, while we’re at your home performing repairs, don’t forget to ask us about booking your maintenance appointment for the future.

Furnace Making Clicking Noise

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

At Scott Temperature, our pros are here to help you relax in quiet, energy-efficient comfort. If your furnace is louder than normal or creating weird sounds, contact us at 785-269-0465 to request an appointment today.
