As your furnace switches on and gets ready to heat your house, it’s expected for it to make some noise. These sounds, like the burners igniting and the blower running, are all part of the usual start-up steps.

But there are a couple of steps you can do to make your furnace quieter this winter.

1. Schedule Annual Furnace Maintenance

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

It can also help our pros discover small issues that can make your furnace annoying. And potentially help you avoid a breakdown on the coldest day of the year. The Indoor Air Quality Association reports that routine maintenance can reduce your probability of furnace breakdowns by up to 95%.

If small furnace troubles go undetected, they may cause trouble in the future. By finding these troubles sooner, our techs can get your furnace repaired before heating season is underway.

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

2. Regularly Put in a New Furnace’s Air Filter

Your air filter helps keep your house’s air fresh and clean. When it turns too clogged, it can make your furnace turn on and off more than it should. Known as short cycling, this can cause your furnace to consume additional fuel and make it stop working faster.

Our advice for installing a new furnace filter:

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

You might have to install a new filter more regularly if you have allergies or pets.

3. Call AZ Air Conditioning and Heating When Your Furnace Is Creating Strange Noises

Some furnaces, particularly older ones, could be louder than others. But if you’re hearing very loud or strange noises, you should call a heating and cooling company like AZ Air Conditioning and Heating for furnace repair in Los Angeles.

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 due to the fact they exhaust fumes differently than older furnaces, and the process can create some moisture. If your furnace is running into difficulties draining this water, it may make gurgling or bubbling sounds. You’ll need professional support for this issue, since it may 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 may mean a couple of things.

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

All that increased gas can make a banging or booming noise when your furnace finally does ignite. But this is more than only an irritating noise, as the accumulated gas is exploding within your furnace. This can crack your furnace’s heat exchanger and cause a life-threatening carbon monoxide leak.

If you’ve neglected regular service for your furnace and you’re noticing this noise, give AZ Air Conditioning and Heating a call at 800-296-5088. Our heating professionals will get your furnace tuned up and ensure it’s running correctly.

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

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

If neither of these things repair the issue, your ductwork might be dirty or undersized, which will be a need for assistance from a professional HVAC technician.

Furnace Making Humming or Buzzing Noise

If your furnace is buzzing or humming, it’s a sign there’s electrical troubles. This is most often seen with a faltering blower fan motor, which will make an annoying buzzing noise when your furnace begins to heat. It may also mean there’s trouble with the capacitor or transformer. All three of these problems need support from a skilled heating and cooling company like AZ Air Conditioning and Heating.

Furnace Making Knocking Noise

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

These troubles are typically uncovered during regular maintenance provided by a certified HVAC pro. So, while we’re at your house working on repairs, don’t forget to inquire about requesting your maintenance appointment for the upcoming year.

Furnace Making Clicking Noise

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