3 Ways to Make Your Furnace Quieter

November 09, 2020

As your furnace starts up and gets ready to add warmth to your house, it’s typical for it to make some noise. These sounds, including the burners firing up and the blower whirring, are all part of the normal start-up process.

But there are a couple of approaches you can do to make your furnace quieter this winter.

1. Book Yearly Furnace Maintenance

Furnace maintenance is highly important, as it keeps your manufacturer warranty in place. This helps shield you if something big goes wrong with your furnace during your warranty time.

It can also help us uncover minor troubles that might make your furnace loud. And possibly help you sidestep a malfunction on the coldest day of the year. The Indoor Air Quality Association reports that regular maintenance can decrease your chance of furnace malfunctions by up to 95%.

If small furnace problems keep on being unnoticed, they can result in a breakdown in the future. By discovering these troubles in advance, our techs can get your furnace taken care of before heating season is at its peak.

And, most critical, pro 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 Change Your Furnace’s Air Filter

Your air filter helps keep your house’s air fresh and clean. When it becomes too dirty, it can make your furnace turn on and off too often. Called short cycling, this can cause your furnace to consume extra fuel and make it stop working faster.

Our advice for changing your furnace filter:

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

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

3. Call TopTec Heating, Cooling, Plumbing & Electrical When Your Furnace is Making Weird Noises

Some furnaces, particularly older ones, might make more noise than others. But if you’re detecting very loud or odd noises, you should get in touch with a heating and cooling company like TopTec Heating, Cooling, Plumbing & Electrical for furnace repair in Libertyville.

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

Furnace Making Gurgling or Bubbling Noise

This noise occurs more commonly with high-efficiency furnaces. That’s due to the fact they exhaust fumes differently than older furnaces, and the process can produce some moisture. If your furnace is running into troubles discharging this water, it may make gurgling or bubbling sounds. You’ll want professional help for this problem, since it may be caused by a blocked drain pipe or clogged drain pan.

Furnace Making Banging Noise

It’s not a good indicator when your furnace is making a banging sound. It may mean a few things.

Haven’t scheduled maintenance this year and your furnace is producing a banging sound when turning on? Its burners can be dirty. Dirty burners can delay ignition, which causes gas to accumulate inside your furnace.

All that accumulated gas can make a banging or booming racket when your furnace eventually does ignite. But this is more than just an irritating noise, because the increased gas is exploding in your furnace. This can crack your furnace’s heat exchanger and make a life-threatening carbon monoxide leak.

If you’ve overlooked regular service for your furnace and you’re hearing this noise, give TopTec Heating, Cooling, Plumbing & Electrical a ring at 847-362-0262. Our heating pros will get your furnace tuned up and make sure it’s running accurately.

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

We suggest first inspecting your furnace’s air filter and installing a new one if it’s clogged. Next, ensure you don’t have too many vents sealed in your residence, as it can throw off air pressure.

If neither of these things repair the problem, your ductwork might be dirty or undersized, which will require assistance from a professional HVAC tech.

Furnace Making Humming or Buzzing Noise

If your furnace is buzzing or humming, it’s a symptom there’s electrical troubles. This is most usually seen with a sputtering blower fan motor, which will make an irritating buzzing noise when your furnace switches on. It can also mean there’s an issue with the capacitor or transformer. All three of these problems need help from a professional heating and cooling company like TopTec Heating, Cooling, Plumbing & Electrical.

Furnace Making Knocking Noise

If your furnace is making knocking sounds, it’s typically a symptom that an internal piece is going out. This could be anything from a bearing to a belt or the gas valve. It could also be a sign that your burners need to be cleaned.

These problems are often caught during yearly maintenance performed by a certified HVAC professional. So, while we’re at your home doing repairs, don’t forget to inquire about requesting your maintenance appointment for the future.

Furnace Making Clicking Noise

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