As your furnace switches on and gets ready to add warmth to your home, it’s common for it to create some noise. These sounds, including the burners firing up and the blower whirring, are all part of the typical start-up process.

But there are several things you can do to make your furnace quieter this winter.

1. Book Annual Furnace Maintenance

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

It can also help our professionals discover minor issues that can make your furnace noisy. 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 probability of furnace malfunctions by up to 95%.

If minor furnace issues go ignored, they may lead to trouble later on. By unearthing these troubles sooner, our professionals can get your furnace repaired before heating season is in full swing.

And most important, pro cleaning and lubrication of your furnace’s moving parts can help make it more efficient. A properly maintained furnace could save up to 30% on your gas expenses, according to the U.S. Department of Energy.

2. Routinely Install a New Furnace’s Air Filter

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

Our advice for changing your furnace filter:

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

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

3. Contact May's Heating & Air When Your Furnace Is Creating Odd Noises

Some furnaces, particularly older ones, can be louder 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 May's Heating & Air for furnace repair in Frederick.

Here are a couple of noises to be on the lookout for, how to take care of 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 differently than older furnaces, and the process can produce some moisture. If your furnace is experiencing difficulties discharging this water, it can make gurgling or bubbling sounds. You’ll need experienced support for this problem, since it might 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 could mean a couple of things.

Haven’t scheduled maintenance recently and your furnace is creating a banging sound when turning on? Its burners might be dirty. Dirty burners can stall ignition, which leads gas to accumulate inside your furnace.

All that built-up gas can create a banging or booming racket when your furnace finally does ignite. But this is more than just an irritating noise, as 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 overlooked regular service for your furnace and you’re hearing this noise, give May's Heating & Air a shout at 301-690-0397. Our heating specialists will get your furnace tuned up and double-check it’s working correctly.

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

We suggest first inspecting your furnace’s air filter and replacing it if it’s clogged. Next, double-check you don’t have too many vents closed in your house, 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 require assistance from a professional HVAC tech.

Furnace Making Humming or Buzzing Noise

If your furnace is buzzing or humming, it’s a flag there’s an electrical issue. This is most frequently seen with a sputtering blower fan motor, which will produce an irritating buzzing noise when your furnace begins to heat. It might also mean there’s a problem with the capacitor or transformer. All three of these problems need assistance from a professional heating and cooling company like May's Heating & Air.

Furnace Making Knocking Noise

If your furnace is making knocking sounds, it’s frequently a symptom that an internal part is breaking down. This could be anything from a bearing to a belt or the gas valve. It may also be a sign that your burners need to be cleaned.

These troubles are often uncovered during yearly maintenance performed by a certified HVAC pro. So, while we’re at your residence working on repairs, don’t forget to inquire about scheduling your maintenance appointment for the upcoming year.

Furnace Making Clicking Noise

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