As your furnace starts up and prepares to heat your house, it’s common for it to produce some noise. These sounds, including the burners igniting and the blower whirring, are all part of the usual start-up steps.

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

1. Request Regular Furnace Maintenance

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

It can also help us spot small issues that might make your furnace annoying. And potentially help you prevent a meltdown on the coldest day of the year. The Indoor Air Quality Association reports that annual maintenance can reduce your likelihood of furnace breakdowns by up to 95%.

If little furnace problems go undetected, they may lead to trouble in the future. By discovering these problems sooner, our technicians can get your furnace fixed before heating season is at its peak.

And most critical, 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 energy bills, according to the U.S. Department of Energy.

2. Frequently Replace Your Furnace’s Air Filter

Your air filter helps keep your home’s air fresh and clean. When it gets too dirty, it can make your furnace turn on and off too frequently. Known as short cycling, this can cause your furnace to eat up additional gas and make it wear out faster.

Our recommendations for changing your furnace filter:

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

You could have to replace your filter more frequently if you have allergies or pets.

3. Call Integrity AC & Heating LLC When Your Furnace Is Producing Weird Noises

Some furnaces, especially older ones, could be noisier than others. But if you’re noticing exceedingly loud or odd noises, you might need to contact a heating and cooling company like Integrity AC & Heating LLC for furnace repair in Phoenix.

Here are several noises to keep an eye out for, how to solve them and when to get in touch with a pro.

Furnace Making Gurgling or Bubbling Noise

This noise is more common with high-efficiency furnaces. That’s because they exhaust fumes in another way than older furnaces, and the process can create some moisture. If your furnace is experiencing difficulties removing this water, it may make gurgling or bubbling sounds. You’ll want pro support for this trouble, since it can 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 might mean a few things.

Haven’t scheduled maintenance recently and your furnace is making a banging sound when beginning? Its burners might be dirty. Dirty burners can stall ignition, which leads gas to accumulate within your furnace.

All that increased gas can create a banging or booming sound when your furnace eventually does ignite. But this is more than merely an irritating noise, as the built-up gas is exploding within your furnace. This can break your furnace’s heat exchanger and create a deadly carbon monoxide leak.

If you’ve overlooked regular maintenance for your furnace and you’re hearing this noise, give Integrity AC & Heating LLC a call at 602-971-0567. Our heating professionals will get your furnace tuned up and double-check it’s working correctly.

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

We advise first inspecting your furnace’s air filter and installing a new one if it’s filthy. Next, ensure you don’t have too many vents closed in your home, as it can make air pressure uneven.

If neither of these steps repair the issue, your ductwork may be dirty or undersized, which will require assistance from a professional HVAC technician.

Furnace Making Humming or Buzzing Noise

If your furnace is buzzing or humming, it’s a sign there’s an electrical issue. This is most frequently seen with a sputtering blower fan motor, which will create an irritating buzzing noise when your furnace starts. It can 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 Integrity AC & Heating LLC.

Furnace Making Knocking Noise

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

These issues are frequently uncovered during annual maintenance provided by a certified HVAC professional. 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 can be the result of things: worn bearings, gas valve issues or ignition issues. All these problems need pro support.
