As your furnace starts up and gets ready to add warmth to your residence, it’s typical for it to create some noise. These sounds, like the burners igniting and the blower running, are all part of the normal start-up steps.

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

1. Book Regular Furnace Maintenance

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

It can also help us find small issues that can make your furnace noisy. And maybe help you avoid a meltdown on the chilliest day of the year. The Indoor Air Quality Association reports that routine maintenance can lower your likelihood of furnace repairs by up to 95%.

If small furnace issues go unnoticed, they may cause trouble in the future. By uncovering these problems sooner, our professionals can get your furnace repaired before heating season begins.

And most essential, specialized cleaning and lubrication of your furnace’s moving parts can help make it more efficient. A correctly maintained furnace could save up to 30% on your heating costs, according to the U.S. Department of Energy.

2. Routinely Install a New Furnace’s Air Filter

Your air filter helps keep your house’s air fresh and clean. When it gets too dirty, it can make your furnace turn on and off too often. Referred to as short cycling, this can cause your furnace to use additional energy and make it wear out faster.

Our suggestions for replacing your furnace filter:

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

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

3. Contact Custom Air Systems Inc When Your Furnace Is Creating Weird Noises

Some furnaces, particularly older ones, may be louder than others. But if you’re detecting very loud or odd noises, you should call a heating and cooling company like Custom Air Systems Inc for furnace repair in Port St. Lucie.

Here are several noises to be on the lookout for, how to repair them and when to call a professional.

Furnace Making Gurgling or Bubbling Noise

This noise is more common with high-efficiency furnaces. That’s since they emit fumes in another way than older furnaces, and the process can create some moisture. If your furnace is running into difficulties discharging this water, it can make gurgling or bubbling sounds. You’ll want pro support for this trouble, since it could 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 few things.

Haven’t scheduled maintenance recently and your furnace is producing a banging sound when starting? Its burners might be dirty. Dirty burners can delay ignition, which leads gas to accumulate in your furnace.

All that increased gas can create a banging or booming noise 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 break your furnace’s heat exchanger and create a dangerous carbon monoxide leak.

If you’ve ignored regular tune-ups for your furnace and you’re noticing this noise, give Custom Air Systems Inc a shout at 772-247-2283. Our heating pros will get your furnace tuned up and double-check it’s running correctly.

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

We recommend first checking your furnace’s air filter and replacing it if it’s clogged. Next, double-check you don’t have too many vents shut in your residence, as it can force air pressure out of balance.

If neither of these steps repair the sound, your ductwork could be dirty or undersized, which will require assistance from a skilled HVAC technician.

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 often seen with a dying blower fan motor, which will create a loud buzzing noise when your furnace switches on. It may also mean there’s an issue with the capacitor or transformer. All three of these issues need support from a professional heating and cooling company like Custom Air Systems Inc.

Furnace Making Knocking Noise

If your furnace is making knocking sounds, it’s frequently a symptom that an internal part is going 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 uncovered during regular maintenance done by a certified HVAC tech. So, while we’re at your home performing repairs, don’t forget to inquire about scheduling your maintenance appointment for next year.

Furnace Making Clicking Noise

A clicking sound might be the result of problems: worn bearings, gas valve problems or ignition issues. All these issues need professional help.
