3 Steps to Make Your Furnace Quieter

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

But there are a couple of things you can do to make your furnace quieter 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 huge stops working in your furnace during your warranty range.

It can also help our professionals discover little problems that could make your furnace annoying. And potentially help you prevent a meltdown on the coldest day of the year. The Indoor Air Quality Association reports that annual maintenance can reduce your likelihood of furnace breakdowns by up to 95%.

If minor furnace troubles are left unnoticed, they may cause a breakdown down the road. By uncovering these issues sooner, our techs can get your furnace fixed before heating season is in full swing.

And, most essential, professional cleaning and lubrication of your furnace’s moving components can help make it more efficient. A correctly 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 house’s air fresh and clean. When it gets 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 consume additional energy and make it stop working more rapidly.

Our recommendations for installing a new furnace filter:

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

You may have to change your filter more often if you have allergies or pets.

3. Call Assured Appliance and Heating & Air When Your Furnace is Creating Weird Noises

Some furnaces, especially older ones, can make more noise than others. But if you’re hearing extremely loud or odd noises, it may be time to get in touch with a heating and cooling company like Assured Appliance and Heating & Air for furnace repair in Genoa.

Here are a couple of noises to be looking for, how to solve them and when to call a professional.

Furnace Making Gurgling or Bubbling Noise

This noise is more common with high-efficiency furnaces. That’s because they emit fumes dissimilarly older furnaces, and the process can produce some moisture. If your furnace is having troubles discharging this water, it can make gurgling or bubbling sounds. You’ll need skilled 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 great sign when your furnace is making a banging sound. It may mean a few things.

Haven’t had maintenance done this year and your furnace is producing a banging sound when turning on? Its burners can be dirty. Dirty burners can delay ignition, which results in gas accumulating inside your furnace.

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

If you’ve overlooked regular service for your furnace and you’re detecting this noise, give Assured Appliance and Heating & Air a call at 847-306-8990. Our heating pros will get your furnace tuned up and double-check it’s operating accurately.

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

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

If neither of these steps fix the sound, your ductwork might be dirty or undersized, which will call for 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 frequently seen with a faltering blower fan motor, which will produce a loud buzzing noise when your furnace turns on. It may also mean there’s trouble with the capacitor or transformer. All three of these issues require support from a skilled heating and cooling company like Assured Appliance and Heating & Air.
