As your furnace turns on and prepares to heat your residence, it’s normal for it to create some noise. These sounds, such as the burners firing up and the blower running, are all part of the normal start-up steps.

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

1. Book Regular Furnace Maintenance

Furnace maintenance is very important, as it keeps your manufacturer warranty in place. This helps shield you if something major stops working in your furnace during your warranty time.

It can also help our pros spot small issues that might make your furnace annoying. And possibly help you avoid a malfunction on the chilliest day of the year. The Indoor Air Quality Association reports that regular maintenance can lower your likelihood of furnace repairs by up to 95%.

If little furnace problems go unnoticed, they may result in trouble in the future. By finding these troubles sooner, our technicians can get your furnace repaired before heating season begins.

And most important, pro cleaning and lubrication of your furnace’s moving components can help make it more efficient. A properly maintained furnace could save up to 30% on your heating 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 gets too filthy, it can make your furnace turn on and off too often. Referred to as short cycling, this can cause your furnace to consume additional fuel and make it stop working faster.

Our suggestions for replacing your furnace filter:

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

You might have to replace your filter more frequently if you have allergies or pets.

3. Call Woody's Sudden Service When Your Furnace Is Producing Odd Noises

Some furnaces, particularly older ones, may be noisier than others. But if you’re hearing very loud or strange noises, you should call a heating and cooling company like Woody's Sudden Service for furnace repair in Manassas.

Here are several noises to be on the lookout for, how to solve them and when to call a pro.

Furnace Making Gurgling or Bubbling Noise

This noise happens more frequently with high-efficiency furnaces. That’s due to the fact they emit fumes differently than older furnaces, and the process can make some moisture. If your furnace is running into difficulties removing this water, it can make gurgling or bubbling sounds. You’ll need skilled support for this problem, since it could 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 several things.

Haven’t had maintenance done recently and your furnace is producing a banging sound when beginning? Its burners may be dirty. Dirty burners can hold up ignition, which causes gas to accumulate within 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, since the accumulated gas is erupting within your furnace. This can damage your furnace’s heat exchanger and create a deadly carbon monoxide leak.

If you’ve forgotten regular service for your furnace and you’re detecting this noise, give Woody's Sudden Service a call at 703-278-2036. Our heating professionals will get your furnace tuned up and ensure it’s working correctly.

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

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

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

Furnace Making Humming or Buzzing Noise

If your furnace is buzzing or humming, it’s a symptom there’s an electrical problem. This is most frequently seen with a dying blower fan motor, which will make an annoying buzzing noise when your furnace turns on. It may also mean there’s trouble with the capacitor or transformer. All three of these troubles need support from an experienced heating and cooling company like Woody's Sudden Service.

Furnace Making Knocking Noise

If your furnace is making knocking sounds, it’s often a symptom that an internal component is going out. This can be anything from a bearing to a belt or the gas valve. It can also be a sign that your burners need to be cleaned.

These problems are usually uncovered during yearly maintenance provided by a certified HVAC professional. So, while we’re at your house working on repairs, don’t forget to ask us about booking your maintenance appointment for the future.

Furnace Making Clicking Noise

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