As your furnace turns on and gets ready to warm up your residence, it’s typical for it to produce some noise. These sounds, such as the burners firing up and the blower running, are all part of the usual start-up steps.

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

1. Book Yearly 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 uncover minor issues that can make your furnace noisy. And potentially help you sidestep a malfunction on the most frigid day of the year. The Indoor Air Quality Association reports that routine maintenance can reduce your probability of furnace meltdowns by up to 95%.

If minor furnace issues go ignored, they may lead to trouble later on. By finding these troubles sooner, our technicians can get your furnace fixed before heating season is in full swing.

And most critical, pro 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 gas costs, according to the U.S. Department of Energy.

2. Frequently Change Your Furnace’s Air Filter

Your air filter helps keep your house’s air fresh and clean. When it becomes too filthy, it can make your furnace turn on and off too often. Called short cycling, this can cause your furnace to eat up additional energy and make it wear out faster.

Our advice for installing a new furnace filter:

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

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

3. Contact Superior Comfort Systems When Your Furnace Is Producing Strange Noises

Some furnaces, particularly older ones, might make more noise than others. But if you’re noticing very loud or strange noises, you should get in touch with a heating and cooling company like Superior Comfort Systems for furnace repair in Hendersonville.

Here are several noises to keep an eye out for, how to repair them and when to contact a pro.

Furnace Making Gurgling or Bubbling Noise

This noise is more common with high-efficiency furnaces. That’s because they emit fumes in another way than older furnaces, and the process can produce some moisture. If your furnace is experiencing difficulties draining this water, it might make gurgling or bubbling sounds. You’ll need skilled support for this trouble, since it may be created by a blocked drain pipe or clogged drain pan.

Furnace Making Banging Noise

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

Haven’t requested maintenance recently and your furnace is making a banging sound when starting? Its burners may be dirty. Dirty burners can hold up ignition, which leads gas to accumulate inside your furnace.

All that built-up gas can create a banging or booming sound when your furnace eventually does ignite. But this is more than just an irritating noise, since the accumulated gas is igniting within your furnace. This can damage your furnace’s heat exchanger and cause a deadly carbon monoxide leak.

If you’ve neglected regular service for your furnace and you’re hearing this noise, give Superior Comfort Systems a shout at 828-202-7025. Our heating specialists will get your furnace tuned up and ensure it’s working correctly.

Your ductwork can also make banging sounds when your furnace switches 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, double-check you don’t have too many vents shut in your home, as it can force air pressure out of balance.

If neither of these methods repair the problem, your ductwork might be dirty or undersized, which will call for assistance from a skilled HVAC tech.

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 usually seen with a dying blower fan motor, which will make an annoying buzzing noise when your furnace turns on. It can also mean there’s a problem with the capacitor or transformer. All three of these problems need support from an experienced heating and cooling company like Superior Comfort Systems.

Furnace Making Knocking Noise

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

These problems are frequently uncovered during yearly maintenance provided by a certified HVAC technician. So, while we’re at your house working on repairs, don’t forget to inquire about booking your maintenance appointment for next year.

Furnace Making Clicking Noise

A clicking sound can be the result of issues: worn bearings, gas valve issues or ignition issues. All these issues need specialized support.
