As your furnace starts up and gets ready to heat your house, it’s common for it to create some noise. These sounds, like the burners firing up and the blower operating, are all part of the normal start-up process.

But there are a few things you can do to make your furnace less noisy this winter.

1. Schedule Annual Furnace Maintenance

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

It can also help us spot small issues that could make your furnace noisy. And maybe help you avoid a meltdown on the coldest day of the year. The Indoor Air Quality Association reports that regular maintenance can lower your probability of furnace malfunctions by up to 95%.

If little furnace problems go undetected, they may lead to trouble down the road. By finding these issues sooner, our professionals can get your furnace fixed before heating season is in full swing.

And most critical, specialized 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. Routinely Put in a New Furnace’s Air Filter

Your air filter helps keep your home’s air fresh and clean. When it becomes too filthy, it can make your furnace turn on and off more than it should. Known as short cycling, this can cause your furnace to eat up additional energy and make it break down faster.

Our advice for replacing your furnace filter:

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

You might have to install a new filter more regularly if you have allergies or pets.

3. Contact Total Assurance AC & Heating When Your Furnace Is Producing Weird Noises

Some furnaces, often older ones, may be louder than others. But if you’re detecting very loud or strange noises, you should contact a heating and cooling company like Total Assurance AC & Heating for furnace repair in Corpus Christi.

Here are a few noises to keep an eye out for, how to take care of them and when to get in touch with a pro.

Furnace Making Gurgling or Bubbling Noise

This noise occurs more commonly with high-efficiency furnaces. That’s because they emit fumes differently than older furnaces, and the process can make some moisture. If your furnace is experiencing difficulties removing this water, it may make gurgling or bubbling sounds. You’ll want experienced support for this issue, since it may be created by a blocked drain pipe or clogged drain pan.

Furnace Making Banging Noise

It’s not a good thing when your furnace is making a banging sound. It can mean a couple of things.

Haven’t requested maintenance recently and your furnace is making a banging sound when starting? Its burners may be dirty. Dirty burners can delay ignition, which causes gas to accumulate within your furnace.

All that built-up gas can create a banging or booming sound when your furnace ultimately does ignite. But this is more than merely an irritating noise, since the increased gas is erupting within your furnace. This can break your furnace’s heat exchanger and cause a dangerous carbon monoxide leak.

If you’ve forgotten regular maintenance for your furnace and you’re noticing this noise, give Total Assurance AC & Heating a shout at 361-217-7080. Our heating professionals will get your furnace tuned up and ensure it’s operating correctly.

Your ductwork can also produce banging sounds when your furnace switches on, 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 dirty. Next, ensure you don’t have too many vents sealed in your residence, as it can force air pressure out of balance.

If neither of these things repair the sound, your ductwork could be dirty or undersized, which will require assistance from a skilled HVAC technician.

Furnace Making Humming or Buzzing Noise

If your furnace is buzzing or humming, it’s a flag 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 switches on. It might also mean there’s an issue with the capacitor or transformer. All three of these troubles need assistance from a skilled heating and cooling company like Total Assurance AC & Heating.

Furnace Making Knocking Noise

If your furnace is making knocking sounds, it’s usually a symptom that an internal component is dying. This could be anything from a bearing to a belt or the gas valve. It could also be a symptom that your burners are dirty.

These troubles are usually uncovered during annual maintenance provided by a certified HVAC technician. So, while we’re at your house working on repairs, don’t forget to check with us about booking your maintenance appointment for the upcoming year.

Furnace Making Clicking Noise

A clicking sound may be the result of problems: worn bearings, gas valve problems or ignition issues. All these issues need pro assistance.
