3 Ways to Make Your Furnace Quieter

November 09, 2020

As your furnace turns on and begins to warm up your home, it’s typical for it to make some noise. These sounds, like the burners igniting and the blower running, are all part of the typical start-up process.

But there are several things you can do to make your furnace less noisy this winter.

1. Book Regular Furnace Maintenance

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

It can also help our professionals find small troubles that could make your furnace loud. And maybe help you sidestep a malfunction on the chilliest day of the year. The Indoor Air Quality Association reports that regular maintenance can lower your probability of furnace meltdowns by up to 95%.

If small furnace problems are left undetected, they could cause trouble in the future. By uncovering these troubles early, our technicians can get your furnace fixed before heating season begins.

And, most essential, professional cleaning and lubrication of your furnace’s moving parts 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. Regularly Put in a New Furnace’s Air Filter

Your air filter helps keep your house’s air fresh and clean. When it turns too clogged, it can make your furnace turn on and off too often. Known as short cycling, this can cause your furnace to use additional energy and make it wear out more rapidly.

Our recommendations for replacing your furnace filter:

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

You could have to get a new filter more regularly if you have allergies or pets.

3. Call Morgner Inc. Air Conditioning & Heating When Your Furnace is Creating Weird Noises

Some furnaces, particularly older ones, might be noisier than others. But if you’re detecting very loud or odd noises, you should call a heating and cooling company like Morgner Inc. Air Conditioning & Heating for furnace repair in St. Louis.

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

Furnace Making Gurgling or Bubbling Noise

This noise happens more frequently with high-efficiency furnaces. That’s because they discharge fumes dissimilarly older furnaces, and the process can create some moisture. If your furnace is having issues draining this water, it can make gurgling or bubbling sounds. You’ll require pro assistance for this trouble, 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 recently and your furnace is producing a banging sound when beginning? Its burners can be dirty. Dirty burners can stall ignition, which results in gas accumulating in your furnace.

All that built-up gas can create a banging or booming noise when your furnace finally does ignite. But this is more than just an irritating noise, since the increased gas is erupting in your furnace. This can crack your furnace’s heat exchanger and cause a dangerous carbon monoxide leak.

If you’ve overlooked annual service for your furnace and you’re noticing this noise, give Morgner Inc. Air Conditioning & Heating a call at 314-262-4541. 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 turns on, as the metal is expanding and contracting.

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

If neither of these steps take care of the sound, your ductwork may be dirty or undersized, which will be a need for assistance from a pro 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 often seen with a faltering blower fan motor, which will create an irritating buzzing noise when your furnace starts. It might also mean there’s an issue with the capacitor or transformer. All three of these troubles call for support from a professional heating and cooling company like Morgner Inc.

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

These issues are usually unearthed during annual maintenance performed by a certified HVAC tech. So, while we’re at your home doing repairs, don’t forget to ask us about requesting your maintenance appointment for the future.
