As your furnace starts up and gets ready to warm up your house, it’s typical for it to create some noise. These sounds, such as the burners firing up and the blower running, are all part of the typical start-up steps.

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

1. Book Yearly Furnace Maintenance

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

It can also help our pros spot little issues that might make your furnace annoying. And potentially help you avoid a meltdown on the chilliest day of the year. The Indoor Air Quality Association reports that regular maintenance can decrease your probability of furnace repairs by up to 95%.

If small furnace issues go undetected, they may cause trouble down the road. By uncovering these problems sooner, our techs can get your furnace repaired before heating season begins.

And most important, pro cleaning and lubrication of your furnace’s moving pieces 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 Replace Your Furnace’s Air Filter

Your air filter helps keep your house’s air fresh and clean. When it becomes too filthy, 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 stop working faster.

Our suggestions for replacing your furnace filter:

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

You may have to get a new filter more regularly if you have allergies or pets.

3. Call Clean Air HVAC When Your Furnace Is Creating Strange Noises

Some furnaces, especially older ones, might be louder than others. But if you’re detecting very loud or odd noises, you might need to contact a heating and cooling company like Clean Air HVAC for furnace repair in Pacheco.

Here are a couple of noises to keep an eye out for, how to repair them and when to call a professional.

Furnace Making Gurgling or Bubbling Noise

This noise occurs more commonly with high-efficiency furnaces. That’s because they discharge fumes in another way than older furnaces, and the process can make some moisture. If your furnace is experiencing difficulties discharging this water, it might make gurgling or bubbling sounds. You’ll want pro 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 positive 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 making a banging sound when beginning? Its burners may be dirty. Dirty burners can stall ignition, which leads gas to accumulate in your furnace.

All that accumulated gas can create a banging or booming racket when your furnace finally does ignite. But this is more than merely an irritating noise, as the built-up gas is erupting within your furnace. This can break your furnace’s heat exchanger and create a life-threatening carbon monoxide leak.

If you’ve ignored regular maintenance for your furnace and you’re detecting this noise, give Clean Air HVAC a call at 925-233-6238. Our heating pros will get your furnace tuned up and make sure it’s running correctly.

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

We suggest first looking at your furnace’s air filter and replacing it if it’s clogged. Next, make sure you don’t have too many vents shut in your home, as it can make air pressure uneven.

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

Furnace Making Humming or Buzzing Noise

If your furnace is buzzing or humming, it’s a sign there’s electrical troubles. This is most usually seen with a dying blower fan motor, which will produce an annoying buzzing noise when your furnace begins to heat. It can also mean there’s a problem with the capacitor or transformer. All three of these troubles need help from a skilled heating and cooling company like Clean Air HVAC.

Furnace Making Knocking Noise

If your furnace is making knocking sounds, it’s typically a symptom that an internal part is breaking down. This can be anything from a bearing to a belt or the gas valve. It may also be an indication that your burners are dirty.

These troubles are usually uncovered during regular maintenance performed by a certified HVAC technician. So, while we’re at your residence working on repairs, don’t forget to ask us about requesting your maintenance appointment for next year.

Furnace Making Clicking Noise

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