As your furnace switches on and gets ready to add warmth to your residence, it’s expected for it to create some noise. These sounds, like the burners firing up and the blower running, are all part of the normal start-up procedures.

But there are a few steps you can do to make your furnace run more quietly this winter.

1. Book Yearly Furnace Maintenance

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

It can also help our professionals spot small issues that could make your furnace annoying. And potentially help you prevent a malfunction on the most frigid day of the year. The Indoor Air Quality Association reports that annual maintenance can reduce your likelihood of furnace malfunctions by up to 95%.

If minor furnace troubles go unnoticed, they may result in trouble down the road. By unearthing these problems sooner, our techs can get your furnace repaired before heating season is underway.

And most critical, 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 heating costs, according to the U.S. Department of Energy.

2. Frequently Put in a New 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. Known as short cycling, this can cause your furnace to use 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 could have to change your filter more regularly if you have allergies or pets.

3. Get in Touch with Farnell Mechanical, Inc. When Your Furnace Is Making Odd Noises

Some furnaces, especially older ones, could make more noise than others. But if you’re detecting exceedingly loud or weird noises, it may be time to contact a heating and cooling company like Farnell Mechanical, Inc. for furnace repair in Auburn and Opelika.

Here are a few noises to be looking for, how to fix them and when to call a specialist.

Furnace Making Gurgling or Bubbling Noise

This noise happens more frequently 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 removing this water, it might make gurgling or bubbling sounds. You’ll want professional support for this issue, 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 might mean a few things.

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

All that accumulated gas can cause a banging or booming noise when your furnace finally does ignite. But this is more than only an irritating noise, because the built-up gas is igniting within your furnace. This can damage your furnace’s heat exchanger and cause a deadly carbon monoxide leak.

If you’ve overlooked regular maintenance for your furnace and you’re noticing this noise, give Farnell Mechanical, Inc. a shout at 334-524-2458. Our heating professionals will get your furnace tuned up and make sure it’s running correctly.

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

We recommend first inspecting your furnace’s air filter and replacing it if it’s clogged. Next, ensure you don’t have too many vents closed in your residence, as it can throw off air pressure.

If neither of these things repair the problem, your ductwork may be dirty or undersized, which will be a need for assistance from a pro HVAC tech.

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 dying blower fan motor, which will create an annoying buzzing noise when your furnace switches on. It may also mean there’s an issue with the capacitor or transformer. All three of these problems need help from a professional heating and cooling company like Farnell Mechanical, Inc..

Furnace Making Knocking Noise

If your furnace is making knocking sounds, it’s often a symptom that an internal piece is worn out. This might be anything from a bearing to a belt or the gas valve. It may also be a sign that your burners need cleaning.

These issues are typically uncovered during regular maintenance done by a certified HVAC technician. So, while we’re at your residence doing repairs, don’t forget to inquire about requesting your maintenance appointment for the future.

Furnace Making Clicking Noise

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