As your furnace starts up and begins to heat your home, it’s common for it to produce some noise. These sounds, including the burners igniting and the blower operating, are all part of the typical start-up process.

But there are a couple of steps you can do to make your furnace less noisy this winter.

1. Request Regular Furnace Maintenance

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

It can also help our pros find little issues that can make your furnace annoying. And maybe help you prevent a malfunction on the chilliest day of the year. The Indoor Air Quality Association reports that regular maintenance can reduce your probability of furnace breakdowns by up to 95%.

If minor furnace troubles go ignored, they may result in trouble later on. By unearthing these troubles sooner, our pros can get your furnace repaired before heating season is underway.

And most important, 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 gas expenses, according to the U.S. Department of Energy.

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

Your air filter helps keep your home’s air fresh and clean. When it becomes too filthy, it can make your furnace turn on and off more than it should. Referred to as short cycling, this can cause your furnace to consume additional fuel and make it wear out faster.

Our suggestions for changing your furnace filter:

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

You may have to change your filter more frequently if you have allergies or pets.

3. Get in Touch with Air Alliance Team When Your Furnace Is Producing Strange Noises

Some furnaces, especially older ones, might make more noise than others. But if you’re hearing very loud or strange noises, it may be time to contact a heating and cooling company like Air Alliance Team for furnace repair in Ballwin and St. Charles.

Here are a couple of noises to be looking for, how to fix them and when to call a specialist.

Furnace Making Gurgling or Bubbling Noise

This noise occurs more commonly with high-efficiency furnaces. That’s since they discharge fumes differently than older furnaces, and the process can produce some moisture. If your furnace is experiencing difficulties removing this water, it may make gurgling or bubbling sounds. You’ll want skilled support for this issue, since it might be created by a blocked drain pipe or clogged drain pan.

Furnace Making Banging Noise

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

Haven’t scheduled maintenance recently and your furnace is producing a banging sound when starting? Its burners could be dirty. Dirty burners can hold up ignition, which results in gas accumulating in your furnace.

All that increased gas can create a banging or booming racket when your furnace ultimately does ignite. But this is more than just an irritating noise, because the built-up gas is exploding within your furnace. This can damage your furnace’s heat exchanger and make a dangerous carbon monoxide leak.

If you’ve overlooked regular service for your furnace and you’re detecting this noise, give Air Alliance Team a shout at 636-206-4584. Our heating professionals will get your furnace tuned up and make sure it’s running correctly.

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

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

If neither of these steps repair the problem, your ductwork could be dirty or undersized, which will require 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 electrical troubles. This is most frequently seen with a faltering blower fan motor, which will create an annoying buzzing noise when your furnace starts. It can also mean there’s a problem with the capacitor or transformer. All three of these problems need help from a skilled heating and cooling company like Air Alliance Team.

Furnace Making Knocking Noise

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

These troubles are frequently uncovered during annual maintenance done by a certified HVAC technician. So, while we’re at your home performing repairs, don’t forget to ask us about scheduling your maintenance appointment for the upcoming year.

Furnace Making Clicking Noise

A clicking sound might be the result of things: worn bearings, gas valve issues or ignition issues. All these troubles need skilled support.
