As your furnace starts up and prepares to heat your house, it’s typical for it to produce some noise. These sounds, such as the burners igniting and the blower whirring, are all part of the usual start-up process.

But there are a couple of approaches you can do to make your furnace run more quietly this winter.

1. Request Annual Furnace Maintenance

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

It can also help us spot minor issues that can make your furnace noisy. And maybe help you prevent a malfunction on the most frigid day of the year. The Indoor Air Quality Association reports that annual maintenance can decrease your probability of furnace meltdowns by up to 95%.

If little furnace troubles go ignored, they may result in trouble down the road. By discovering these issues sooner, our pros can get your furnace taken care of before heating season is underway.

And most important, specialized cleaning and lubrication of your furnace’s moving parts can help make it more efficient. A correctly maintained furnace could save up to 30% on your heating costs, 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 gets too dirty, it can make your furnace turn on and off too often. Called short cycling, this can cause your furnace to use additional fuel and make it break down faster.

Our advice for changing your furnace filter:

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

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

3. Contact Giordanos Heating and Air Conditioning When Your Furnace Is Producing Strange Noises

Some furnaces, especially older ones, might make more noise than others. But if you’re detecting very loud or odd noises, you should get in touch with a heating and cooling company like Giordanos Heating and Air Conditioning for furnace repair in Derby.

Here are several noises to keep an eye out for, how to take care of them and when to call a professional.

Furnace Making Gurgling or Bubbling Noise

This noise is more common with high-efficiency furnaces. That’s due to the fact they discharge fumes in another way than older furnaces, and the process can create some moisture. If your furnace is having difficulties discharging this water, it may make gurgling or bubbling sounds. You’ll want experienced 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 good thing when your furnace is making a banging sound. It can mean several things.

Haven’t had maintenance done recently and your furnace is making a banging sound when starting? Its burners might be dirty. Dirty burners can stall ignition, which leads gas to accumulate within your furnace.

All that accumulated gas can make a banging or booming sound when your furnace ultimately does ignite. But this is more than merely an irritating noise, because the built-up gas is erupting within your furnace. This can damage your furnace’s heat exchanger and cause a life-threatening carbon monoxide leak.

If you’ve overlooked regular service for your furnace and you’re detecting this noise, give Giordanos Heating and Air Conditioning a ring at 203-772-8319. Our heating professionals will get your furnace tuned up and make sure it’s running correctly.

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

We suggest first looking at your furnace’s air filter and installing a new one if it’s dirty. 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 issue, your ductwork could 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 symptom there’s an electrical issue. This is most usually seen with a sputtering blower fan motor, which will produce an irritating buzzing noise when your furnace starts. It can also mean there’s trouble with the capacitor or transformer. All three of these issues need assistance from an experienced heating and cooling company like Giordanos Heating and Air Conditioning.

Furnace Making Knocking Noise

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

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

Furnace Making Clicking Noise

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