3 Ways to Make Your Furnace Work Less Noisily

November 09, 2020

As your furnace switches on and begins to heat your home, it’s expected for it to make some noise. These sounds, such as the burners igniting and the blower operating, are all part of the typical start-up process.

But there are several steps you can do to make your furnace run more quietly this winter.

1. Book Annual Furnace Maintenance

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

It can also help us spot small problems that can make your furnace noisy. And potentially help you sidestep a breakdown on the coldest day of the year. The Indoor Air Quality Association reports that routine maintenance can reduce your chance of furnace repairs by up to 95%.

If little furnace problems are left ignored, they might result in a breakdown down the road. By unearthing these troubles in advance, our pros can get your furnace taken care of before heating season is at its peak.

And, most essential, professional 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 expenses, according to the U.S. Department of Energy.

2. Frequently Install a New Furnace’s Air Filter

Your air filter helps keep your residence’s air fresh and clean. When it becomes too clogged, it can make your furnace turn on and off too often. Known as short cycling, this can cause your furnace to use more fuel and make it stop working more quickly.

Our advice for installing a new furnace filter:

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

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

3. Contact Lanz Furnace and Fireplace When Your Furnace is Creating Odd Noises

Some furnaces, often older ones, can be noisier than others. But if you’re noticing extremely loud or weird noises, you should contact a heating and cooling company like Lanz Furnace and Fireplace for furnace repair in Monroe.

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

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 produce some moisture. If your furnace is running into difficulties discharging this water, it could make gurgling or bubbling sounds. You’ll require pro help for this issue, since it could 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 requested maintenance recently and your furnace is making a banging sound when turning on? Its burners may be dirty. Dirty burners can stall ignition, which leads gas to accumulate inside your furnace.

All that accumulated gas can create a banging or booming noise when your furnace ultimately does ignite. But this is more than only an annoying noise, since the increased gas is erupting within your furnace. This can damage your furnace’s heat exchanger and make a dangerous carbon monoxide leak.

If you’ve forgotten annual service for your furnace and you’re noticing this noise, give Lanz Furnace and Fireplace a call at 608-291-3606. 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 switches on, as the metal is expanding and contracting.

We suggest first checking your furnace’s air filter and getting a new one if it’s dirty. Next, make sure you don’t have too many vents sealed in your residence, as it can make air pressure uneven.

If neither of these steps fix the problem, your ductwork could be dirty or undersized, which will require assistance from a pro HVAC specialist.

Furnace Making Humming or Buzzing Noise

If your furnace is buzzing or humming, it’s a symptom there’s an electrical problem. This is most often seen with a sputtering blower fan motor, which will produce an annoying buzzing noise when your furnace begins to heat. It could also mean there’s an issue with the capacitor or transformer. All three of these troubles require help from a skilled heating and cooling company like Lanz Furnace and Fireplace.

Furnace Making Knocking Noise

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

These issues are often unearthed during annual maintenance performed by a certified HVAC technician. So, while we’re at your house doing repairs, don’t forget to inquire about requesting your maintenance appointment for next year.

Furnace Making Clicking Noise

A clicking sound might be created by things: worn bearings, gas valve issues or ignition troubles. All these troubles need pro support.
