3 Ways to Make Your Furnace Run with Less Noise

November 09, 2020

As your furnace switches on and begins to heat your home, it’s expected for it to produce some noise. These sounds, like the burners firing up and the blower running, are all part of the normal start-up process.

But there are a few steps 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 valid. This helps shield you if something major goes wrong with your furnace during your warranty range.

It can also help our professionals find small problems that can make your furnace noisy. And maybe help you prevent a breakdown on the chilliest day of the year. The Indoor Air Quality Association reports that annual maintenance can decrease your chance of furnace breakdowns by up to 95%.

If little furnace issues go ignored, they could lead to an issue later on. By discovering these problems sooner, our technicians can get your furnace fixed before heating season begins.

And, most critical, specialized cleaning and lubrication of your furnace’s moving pieces can help make it more efficient. A properly maintained furnace could save up to 30% on your heating bills, according to the U.S. Department of Energy.

2. Routinely Put in a New Furnace’s Air Filter

Your air filter helps keep your house’s air fresh and clean. When it turns too filthy, it can make your furnace turn on and off too frequently. Known as short cycling, this can cause your furnace to eat up more energy and make it stop working more rapidly.

Our recommendations for installing a new furnace filter:

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

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

3. Contact Central Air LLC When Your Furnace is Producing Weird Noises

Some furnaces, especially older ones, could be noisier than others. But if you’re noticing extremely loud or odd noises, you might need to get in touch with a heating and cooling company like Central Air LLC for furnace repair in Brookfield.

Here are a few noises to be on the lookout for, how to repair them and when to contact a professional.

Furnace Making Gurgling or Bubbling Noise

This noise happens more frequently with high-efficiency furnaces. That’s because they discharge fumes differently than older furnaces, and the process can produce some moisture. If your furnace is running into issues removing this water, it could make gurgling or bubbling sounds. You’ll want skilled assistance for this trouble, since it may be caused by a blocked drain pipe or clogged drain pan.

Furnace Making Banging Noise

It’s not a good indicator when your furnace is making a banging sound. It could mean a couple of things.

Haven’t had maintenance done lately and your furnace is creating a banging sound when beginning? Its burners may be dirty. Dirty burners can stall ignition, which causes gas to accumulate in your furnace.

All that accumulated gas can create a banging or booming sound when your furnace finally does ignite. But this is more than merely an annoying noise, as the built-up gas is exploding in your furnace. This can crack your furnace’s heat exchanger and make a deadly carbon monoxide leak.

If you’ve ignored annual tune-ups for your furnace and you’re hearing this noise, give Central Air LLC a call at 203-357-5913. Our heating specialists will get your furnace tuned up and double-check it’s running accurately.

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

We advise first checking your furnace’s air filter and installing a new one if it’s clogged. Next, ensure you don’t have too many vents shut in your home, as it can make air pressure uneven.

If neither of these methods repair the problem, your ductwork could be dirty or undersized, which will require assistance from a skilled HVAC technician.

Furnace Making Humming or Buzzing Noise

If your furnace is buzzing or humming, it’s a sign there’s an electrical issue. This is most frequently seen with a faltering blower fan motor, which will make an annoying buzzing noise when your furnace turns on. It might also mean there’s an issue with the capacitor or transformer. All three of these issues call for help from a professional heating and cooling company like Central Air LLC.

Furnace Making Knocking Noise

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

These issues are often unearthed during yearly maintenance performed by a certified HVAC pro. So, while we’re at your home working on repairs, don’t forget to ask us about booking your maintenance appointment for the future.

Furnace Making Clicking Noise

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

At Central Air LLC, our specialists are here to help you enjoy quiet, energy-efficient comfort. If your furnace is louder than normal or creating odd sounds, contact us at 203-357-5913 to get an appointment right away.
