As your furnace turns on and begins to warm up your home, it’s normal for it to produce some noise. These sounds, like the burners lighting and the blower running, are all part of the usual start-up process.

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

1. Book Yearly Furnace Maintenance

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

It can also help us spot small issues that could make your furnace loud. And possibly help you prevent a breakdown on the chilliest day of the year. The Indoor Air Quality Association reports that annual maintenance can lower your probability of furnace repairs by up to 95%.

If little furnace troubles go ignored, they may lead to trouble later on. By uncovering these problems sooner, our professionals can get your furnace fixed before heating season is in full swing.

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

2. Frequently Replace Your Furnace’s Air Filter

Your air filter helps keep your home’s air fresh and clean. When it gets too clogged, it can make your furnace turn on and off too frequently. Referred to as short cycling, this can cause your furnace to use additional fuel and make it stop working faster.

Our recommendations for installing a new furnace filter:

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

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

3. Contact Connolly Electric & Mechanical When Your Furnace Is Creating Odd Noises

Some furnaces, especially older ones, might make more noise than others. But if you’re detecting extremely loud or strange noises, you might need to call a heating and cooling company like Connolly Electric & Mechanical for furnace repair in Cottonwood & Prescott.

Here are several noises to be looking for, how to fix them and when to contact a professional.

Furnace Making Gurgling or Bubbling Noise

This noise happens more frequently with high-efficiency furnaces. That’s due to the fact they exhaust fumes in another way than older furnaces, and the process can make some moisture. If your furnace is running into difficulties draining this water, it could make gurgling or bubbling sounds. You’ll want pro support for this problem, since it can 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 can mean a few things.

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

All that increased gas can cause a banging or booming sound when your furnace eventually does ignite. But this is more than only an irritating noise, because the built-up gas is erupting within your furnace. This can break your furnace’s heat exchanger and cause a dangerous carbon monoxide leak.

If you’ve neglected regular tune-ups for your furnace and you’re noticing this noise, give Connolly Electric & Mechanical a shout at 928-251-4327. Our heating pros will get your furnace tuned up and double-check it’s running correctly.

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

We suggest first checking your furnace’s air filter and installing a new one if it’s dirty. Next, ensure you don’t have too many vents shut in your house, as it can throw off air pressure.

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

Furnace Making Humming or Buzzing Noise

If your furnace is buzzing or humming, it’s a sign there’s electrical troubles. This is most frequently seen with a dying blower fan motor, which will make an irritating buzzing noise when your furnace switches on. It can also mean there’s a problem with the capacitor or transformer. All three of these issues need help from an experienced heating and cooling company like Connolly Electric & Mechanical.

Furnace Making Knocking Noise

If your furnace is making knocking sounds, it’s often a symptom that an internal piece is going out. This could be anything from a bearing to a belt or the gas valve. It might also be an indication that your burners are dirty.

These issues are usually uncovered during regular maintenance done by a certified HVAC pro. So, while we’re at your residence performing repairs, don’t forget to check with us about requesting your maintenance appointment for next year.

Furnace Making Clicking Noise

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