3 Ways to Make Your Furnace Work More Quietly

November 09, 2020

As your furnace switches on and gets ready to heat your house, it’s typical for it to create some noise. These sounds, such as the burners lighting and the blower running, are all part of the normal start-up procedures.

But there are several steps you can do to make your furnace less noisy this winter.

1. Book Regular Furnace Maintenance

Furnace maintenance is extremely important, as it keeps your manufacturer warranty in place. This helps defend you if something major malfunctions in your furnace during your warranty time.

It can also help us discover minor troubles that could make your furnace noisy. And potentially help you sidestep a meltdown on the coldest day of the year. The Indoor Air Quality Association reports that annual maintenance can reduce your likelihood of furnace meltdowns by up to 95%.

If minor furnace troubles go unnoticed, they might cause an issue down the road. By discovering these troubles sooner, our professionals can get your furnace fixed before heating season begins.

And, most critical, professional cleaning and lubrication of your furnace’s moving components can help make it more efficient. A well- maintained furnace could save up to 30% on your gas bills, according to the U.S. Department of Energy.

2. Frequently Change Your Furnace’s Air Filter

Your air filter helps keep your home’s air fresh and clean. When it turns too filthy, it can make your furnace turn on and off too often. Called short cycling, this can cause your furnace to consume more energy and make it wear out faster.

Our advice for installing a new furnace filter:

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

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

3. Call American HVAC Inc When Your Furnace is Creating Weird Noises

Some furnaces, especially older ones, may be noisier than others. But if you’re noticing very loud or weird noises, it may be time to get in touch with a heating and cooling company like American HVAC Inc for furnace repair in San Jose.

Here are several noises to be looking for, how to repair them and when to call 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 may make gurgling or bubbling sounds. You’ll need experienced assistance for this trouble, since it might be the result of by a blocked drain pipe or clogged drain pan.

Furnace Making Banging Noise

It’s not a positive sign when your furnace is making a banging sound. It can mean a few things.

Haven’t had maintenance done recently and your furnace is producing a banging sound when beginning? Its burners can be dirty. Dirty burners can hold up ignition, which leads gas to accumulate inside your furnace.

All that built-up gas can cause a banging or booming sound when your furnace ultimately does ignite. But this is more than just a bothersome noise, since the built-up gas is erupting in your furnace. This can damage your furnace’s heat exchanger and cause a life-threatening carbon monoxide leak.

If you’ve ignored yearly tune-ups for your furnace and you’re detecting this noise, give American HVAC Inc a ring at 408-215-1018. Our heating specialists will get your furnace tuned up and ensure it’s operating correctly.

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

We advise first looking at your furnace’s air filter and installing a new one if it’s filthy. Next, double-check you don’t have too many vents sealed in your home, as it can force air pressure out of balance.

If neither of these methods repair the problem, your ductwork may be dirty or undersized, which will call for assistance from a skilled HVAC specialist.

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 often seen with a dying blower fan motor, which will make an irritating buzzing noise when your furnace switches on. It might also mean there’s trouble with the capacitor or transformer. All three of these problems call for help from a professional heating and cooling company like American HVAC Inc.

Furnace Making Knocking Noise

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

These troubles are often uncovered during regular maintenance done by a certified HVAC technician. So, while we’re at your house working on repairs, don’t forget to check with us about scheduling your maintenance appointment for next year.

Furnace Making Clicking Noise

A clicking sound might be the result of problems: worn bearings, gas valve troubles or ignition issues. All these issues need skilled support.
