As your furnace switches on and begins to add warmth to your home, it’s common for it to make some noise. These sounds, such as the burners igniting and the blower operating, are all part of the normal start-up procedures.

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

1. Book Annual Furnace Maintenance

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

It can also help our professionals spot minor issues that could make your furnace loud. And potentially help you sidestep a breakdown on the chilliest day of the year. The Indoor Air Quality Association reports that annual maintenance can reduce your chance of furnace meltdowns by up to 95%.

If minor furnace issues go undetected, they may cause trouble later on. By uncovering these issues sooner, our pros can get your furnace repaired before heating season is in full swing.

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 energy costs, according to the U.S. Department of Energy.

2. Regularly Replace Your Furnace’s Air Filter

Your air filter helps keep your house’s air fresh and clean. When it becomes too dirty, 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 energy and make it break down faster.

Our suggestions for replacing your furnace filter:

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

You may have to install a new filter more often if you have allergies or pets.

3. Call AZ Air Conditioning and Heating When Your Furnace Is Producing Weird Noises

Some furnaces, particularly older ones, could make more noise than others. But if you’re noticing extremely loud or odd noises, you should contact a heating and cooling company like AZ Air Conditioning and Heating for furnace repair in Los Angeles.

Here are several noises to be looking for, how to solve 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 emit fumes in another way than older furnaces, and the process can make some moisture. If your furnace is running into difficulties discharging this water, it could make gurgling or bubbling sounds. You’ll require professional support for this trouble, 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 may mean a couple of things.

Haven’t requested maintenance recently and your furnace is making a banging sound when turning on? Its burners could be dirty. Dirty burners can hold up ignition, which results in gas accumulating inside your furnace.

All that accumulated gas can make a banging or booming noise when your furnace ultimately does ignite. But this is more than only an irritating noise, since the built-up gas is exploding within your furnace. This can crack your furnace’s heat exchanger and make a dangerous carbon monoxide leak.

If you’ve ignored regular maintenance for your furnace and you’re detecting this noise, give AZ Air Conditioning and Heating a shout at 800-296-5088. Our heating specialists will get your furnace tuned up and ensure it’s working correctly.

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

We advise first checking your furnace’s air filter and installing a new one if it’s filthy. Next, ensure you don’t have too many vents sealed in your home, as it can make air pressure uneven.

If neither of these things repair the sound, your ductwork could be dirty or undersized, which will require assistance from a skilled HVAC specialist.

Furnace Making Humming or Buzzing Noise

If your furnace is buzzing or humming, it’s a sign there’s an electrical issue. This is most frequently seen with a sputtering blower fan motor, which will produce an irritating buzzing noise when your furnace starts. It might also mean there’s an issue with the capacitor or transformer. All three of these issues need support from an experienced heating and cooling company like AZ Air Conditioning and Heating.

Furnace Making Knocking Noise

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

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

Furnace Making Clicking Noise

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