As your furnace turns on and gets ready to add warmth to your house, it’s expected for it to make some noise. These sounds, including the burners firing up and the blower whirring, are all part of the usual start-up process.
But there are a couple of steps you can do to make your furnace run more quietly this winter.
1. Request Regular Furnace Maintenance
Furnace maintenance is extremely important, since it keeps your manufacturer warranty valid. This helps protect you if something major stops working in your furnace during your warranty range.
It can also help our professionals uncover minor issues that can make your furnace noisy. And maybe help you avoid a meltdown on the coldest day of the year. The Indoor Air Quality Association reports that routine maintenance can decrease your probability of furnace meltdowns by up to 95%.
If minor furnace issues go unnoticed, they may cause trouble later on. By discovering these issues sooner, our technicians can get your furnace repaired before heating season is in full swing.
And most critical, pro cleaning and lubrication of your furnace’s moving components can help make it more efficient. A correctly maintained furnace could save up to 30% on your heating bills, according to the U.S. Department of Energy.
2. Regularly Install a New Furnace’s Air Filter
Your air filter helps keep your house’s air fresh and clean. When it turns too filthy, it can make your furnace turn on and off too frequently. Known as short cycling, this can cause your furnace to eat up additional energy and make it wear out faster.
Our recommendations for replacing your furnace filter:
Flat filter: Monthly
Pleated filter: Every three months
You may have to replace your filter more often if you have allergies or pets.
3. Call Bishop’s HVAC When Your Furnace Is Creating Strange Noises
Some furnaces, particularly older ones, might be louder than others. But if you’re detecting extremely loud or odd noises, you should get in touch with a heating and cooling company like Bishop’s HVAC for furnace repair in Sacramento.
Here are several noises to keep an eye out for, how to take care of them and when to call a pro.
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 create some moisture. If your furnace is experiencing difficulties draining this water, it can make gurgling or bubbling sounds. You’ll need skilled support for this issue, since it might 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 starting? Its burners could be dirty. Dirty burners can hold up ignition, which leads gas to accumulate in 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, because the accumulated gas is exploding within your furnace. This can damage your furnace’s heat exchanger and create a deadly carbon monoxide leak.
If you’ve neglected regular service for your furnace and you’re hearing this noise, give Bishop’s HVAC a shout at 916-591-6889. Our heating professionals will get your furnace tuned up and ensure it’s running correctly.
Your ductwork can also produce banging sounds when your furnace starts, since the metal is expanding and contracting.
We recommend first looking at your furnace’s air filter and getting a new one if it’s dirty. Next, ensure you don’t have too many vents sealed in your house, as it can force air pressure out of balance.
If neither of these methods repair the issue, your ductwork might be dirty or undersized, which will be a need for assistance from a skilled HVAC specialist.
Furnace Making Humming or Buzzing Noise
If your furnace is buzzing or humming, it’s a flag there’s an electrical issue. This is most often seen with a faltering blower fan motor, which will make an annoying buzzing noise when your furnace switches on. It could also mean there’s an issue with the capacitor or transformer. All three of these troubles need support from an experienced heating and cooling company like Bishop’s HVAC.
Furnace Making Knocking Noise
If your furnace is making knocking sounds, it’s typically a symptom that an internal component is worn out. This can be anything from a bearing to a belt or the gas valve. It might also be a sign that your burners need cleaning.
These troubles are frequently uncovered during yearly maintenance performed by a certified HVAC professional. So, while we’re at your home working on repairs, don’t forget to check with us about booking your maintenance appointment for the upcoming year.
Furnace Making Clicking Noise
A clicking sound could be the result of troubles: worn bearings, gas valve issues or ignition problems. All these troubles need professional support.
