3 Steps to Make Your Furnace Less Noisy

November 09, 2020

As your furnace starts up and prepares to warm up your home, it’s common for it to produce some noise. These sounds, such as the burners igniting and the blower running, are all part of the usual start-up procedures.

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

1. Request Annual Furnace Maintenance

Furnace maintenance is extremely important, as it keeps your manufacturer warranty in place. This helps defend you if something big malfunctions in your furnace during your warranty range.

It can also help us find small problems that can make your furnace annoying. 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 likelihood of furnace breakdowns by up to 95%.

If minor furnace problems are left unnoticed, they may lead to trouble down the road. By finding these troubles sooner, our technicians can get your furnace fixed before heating season is at its peak.

And, most essential, specialized 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 utility expenses, according to the U.S. Department of Energy.

2. Regularly Install a New Furnace’s Air Filter

Your air filter helps keep your home’s air fresh and clean. When it turns too filthy, it can make your furnace turn on and off too often. Known as short cycling, this can cause your furnace to consume more gas and make it stop working more rapidly.

Our recommendations for replacing your furnace filter:

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

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

3. Contact Air Houston Mechanical LLC When Your Furnace is Producing Odd Noises

Some furnaces, often older ones, can make more noise than others. But if you’re hearing exceedingly loud or strange noises, you should call a heating and cooling company like Air Houston Mechanical LLC for furnace repair in Huffman.

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

Furnace Making Gurgling or Bubbling Noise

This noise occurs more commonly with high-efficiency furnaces. That’s due to the fact they exhaust fumes in another way than older furnaces, and the process can make some moisture. If your furnace is having issues draining this water, it may make gurgling or bubbling sounds. You’ll want skilled help for this problem, since it may be created 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 might mean a couple of things.

Haven’t had maintenance done this year and your furnace is producing a banging sound when beginning? Its burners may be dirty. Dirty burners can stall ignition, which results in gas accumulating within your furnace.

All that built-up gas can make a banging or booming racket when your furnace eventually does ignite. But this is more than merely an irritating noise, since the increased gas is exploding inside your furnace. This can crack your furnace’s heat exchanger and cause a life-threatening carbon monoxide leak.

If you’ve neglected regular tune-ups for your furnace and you’re hearing this noise, give Air Houston Mechanical LLC a shout at 832-777-1521. Our heating pros will get your furnace tuned up and ensure it’s running correctly.

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

We advise first inspecting your furnace’s air filter and replacing it if it’s dirty. Next, make sure you don’t have too many vents closed in your house, as it can throw off air pressure.

If neither of these things take care of the issue, your ductwork might be dirty or undersized, which will be a need for assistance from a professional HVAC specialist.

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 make an irritating buzzing noise when your furnace begins to heat. It can also mean there’s an issue with the capacitor or transformer. All three of these problems call for support from a skilled heating and cooling company like Air Houston Mechanical LLC.

Furnace Making Knocking Noise

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

These troubles are often caught during annual maintenance done by a certified HVAC pro. So, while we’re at your home doing repairs, don’t forget to ask us about booking your maintenance appointment for next year.

Furnace Making Clicking Noise

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