3 Steps to Make Your Furnace Less Noisy

November 09, 2020

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

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

1. Request Yearly Furnace Maintenance

Furnace maintenance is extremely important, because it keeps your manufacturer warranty in place. This helps protect you if something big malfunctions in your furnace during your warranty period.

It can also help our professionals uncover small problems that could make your furnace loud. And possibly help you avoid a meltdown on the most frigid day of the year. The Indoor Air Quality Association reports that regular maintenance can reduce your chance of furnace breakdowns by up to 95%.

If small furnace troubles keep on being unnoticed, they can lead to a breakdown in the future. By discovering these problems in advance, our professionals 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 parts can help make it more efficient. A well- maintained furnace could save up to 30% on your heating costs, 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 often. Referred to 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 could have to change your filter more regularly if you have allergies or pets.

3. Contact Aggressive Mechanical When Your Furnace is Creating Odd Noises

Some furnaces, especially older ones, might make more noise than others. But if you’re detecting extremely loud or odd noises, it may be time to contact a heating and cooling company like Aggressive Mechanical for furnace repair in Neptune City.

Here are a few noises to be on the lookout for, how to repair them and when to contact a pro.

Furnace Making Gurgling or Bubbling Noise

This noise occurs more commonly with high-efficiency furnaces. That’s due to the fact they discharge fumes differently than older furnaces, and the process can make some moisture. If your furnace is experiencing issues draining this water, it can make gurgling or bubbling sounds. You’ll require experienced help for this trouble, since it may 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 could mean a couple of things.

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

All that built-up gas can create a banging or booming racket when your furnace eventually does ignite. But this is more than just an annoying noise, as the built-up gas is erupting inside 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 hearing this noise, give Aggressive Mechanical a call at 732-806-5536. Our heating specialists will get your furnace tuned up and make sure it’s running safely.

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

We advise first checking your furnace’s air filter and replacing it if it’s filthy. Next, double-check you don’t have too many vents closed in your residence, as it can throw off air pressure.

If neither of these steps take care of the sound, your ductwork could be dirty or undersized, which will require assistance from a pro 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 faltering blower fan motor, which will make a loud 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 need assistance from a professional heating and cooling company like Aggressive Mechanical.

Furnace Making Knocking Noise

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

These troubles are usually caught during annual maintenance done by a certified HVAC technician. So, while we’re at your house doing repairs, don’t forget to check with us about booking your maintenance appointment for the future.

Furnace Making Clicking Noise

A clicking sound could be created by things: worn bearings, gas valve problems or ignition problems. All these troubles need professional help.
