3 Steps to Make Your Furnace Quieter

As your furnace switches on and gets ready to heat your home, it’s normal for it to make some noise. These sounds, such as the burners lighting and the blower running, are all part of the usual start-up steps.

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

1. Schedule Annual Furnace Maintenance

Furnace maintenance is very important, because it keeps your manufacturer warranty in place. This helps protect you if something major stops working in your furnace during your warranty time.

It can also help us find little issues that might make your furnace annoying. And potentially help you sidestep a malfunction on the chilliest day of the year. The Indoor Air Quality Association reports that regular maintenance can decrease your chance of furnace repairs by up to 95%.

If little furnace troubles go ignored, they might result in a breakdown down the road. By discovering these issues sooner, our professionals can get your furnace repaired before heating season is underway.

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

2. Routinely Change Your Furnace’s Air Filter

Your air filter helps keep your residence’s air fresh and clean. When it becomes too dirty, it can make your furnace turn on and off too frequently. Referred to as short cycling, this can cause your furnace to eat up extra fuel and make it stop working more quickly.

Our recommendations for replacing your furnace filter:

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

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

3. Call B & B Heating & Cooling When Your Furnace is Producing Strange Noises

Some furnaces, particularly older ones, may be noisier than others. But if you’re noticing very loud or strange noises, you should call a heating and cooling company like B & B Heating & Cooling for furnace repair in Florissant.

Here are a couple of noises to keep an eye out for, how to solve them and when to contact a specialist.

Furnace Making Gurgling or Bubbling Noise

This noise occurs more commonly with high-efficiency furnaces. That’s due to the fact they discharge fumes in another way than older furnaces, and the process can produce some moisture. If your furnace is running into troubles draining this water, it could make gurgling or bubbling sounds. You’ll need skilled support for this trouble, since it may be the result of by a blocked drain pipe or clogged drain pan.

Furnace Making Banging Noise

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

Haven’t scheduled maintenance lately and your furnace is creating a banging sound when beginning? Its burners might be dirty. Dirty burners can hold up ignition, which leads gas to accumulate in your furnace.

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

If you’ve forgotten annual maintenance for your furnace and you’re hearing this noise, give B & B Heating & Cooling a ring at 314-325-7552. Our heating professionals will get your furnace tuned up and double-check it’s operating safely.

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

We suggest first looking at your furnace’s air filter and installing a new one if it’s filthy. Next, double-check you don’t have too many vents sealed in your home, as it can throw off air pressure.

If neither of these steps repair the sound, your ductwork could be dirty or undersized, which will call for assistance from a professional HVAC specialist.

Furnace Making Humming or Buzzing Noise

If your furnace is buzzing or humming, it’s a sign there’s an electrical problem. This is most frequently seen with a faltering blower fan motor, which will make a loud 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 need assistance from a professional heating and cooling company like B & B Heating & Cooling.

Furnace Making Knocking Noise

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

These issues are typically uncovered during regular maintenance done by a certified HVAC pro. So, while we’re at your home doing repairs, don’t forget to inquire about scheduling your maintenance appointment for the future.

Furnace Making Clicking Noise

A clicking sound could be created by problems: worn bearings, gas valve issues or ignition problems. All these issues require professional help.
