3 Ways to Make Your Furnace Operate More Quietly

November 09, 2020

As your furnace turns on and gets ready to add warmth to your house, it’s expected for it to make some noise. These sounds, such as the burners lighting and the blower operating, are all part of the usual start-up procedures.

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

1. Book Regular Furnace Maintenance

Furnace maintenance is extremely important, since it keeps your manufacturer warranty ongoing. This helps defend you if something big goes wrong with your furnace during your warranty range.

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

If minor furnace issues keep on being undetected, they could lead to a malfunction later on. By unearthing these problems early, our professionals can get your furnace taken care of before heating season begins.

And, most critical, pro 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 expenses, according to the U.S. Department of Energy.

2. Routinely Replace Your 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. Referred to as short cycling, this can cause your furnace to use extra fuel and make it stop working more quickly.

Our suggestions for installing a new furnace filter:

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

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

3. Contact Ilten's Incorporated When Your Furnace is Making Odd Noises

Some furnaces, especially older ones, might be louder than others. But if you’re noticing extremely loud or strange noises, you should get in touch with a heating and cooling company like Ilten's Incorporated for furnace repair in Cedar Rapids.

Here are several noises to be on the lookout 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 emit fumes in another way than older furnaces, and the process can make some moisture. If your furnace is experiencing issues draining this water, it may make gurgling or bubbling sounds. You’ll need skilled help for this problem, since it may be created by a blocked drain pipe or clogged drain pan.

Furnace Making Banging Noise

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

Haven’t requested maintenance lately and your furnace is making a banging sound when turning on? Its burners might be dirty. Dirty burners can hold up ignition, which leads gas to accumulate in your furnace.

All that increased gas can create a banging or booming racket when your furnace eventually does ignite. But this is more than merely an annoying noise, as the built-up gas is igniting inside your furnace. This can damage your furnace’s heat exchanger and make a deadly carbon monoxide leak.

If you’ve neglected yearly tune-ups for your furnace and you’re hearing this noise, give Ilten's Incorporated a call at 319-208-3295. Our heating pros will get your furnace tuned up and double-check it’s working correctly.

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

We suggest first inspecting your furnace’s air filter and replacing it if it’s dirty. Next, double-check you don’t have too many vents closed in your home, as it can make air pressure uneven.

If neither of these steps fix the sound, your ductwork might be dirty or undersized, which will require assistance from a skilled 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 often seen with a faltering blower fan motor, which will produce an irritating buzzing noise when your furnace switches on. It could also mean there’s a problem with the capacitor or transformer. All three of these issues require help from a skilled heating and cooling company like Ilten's Incorporated.

Furnace Making Knocking Noise

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

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

Furnace Making Clicking Noise

A clicking sound could be created by troubles: worn bearings, gas valve troubles or ignition troubles. All these issues require professional support.
