As your furnace switches on and begins to heat your residence, it’s common for it to make some noise. These sounds, including the burners firing up and the blower whirring, are all part of the normal start-up process.
But there are a few approaches you can do to make your furnace run more quietly this winter.
1. Book Annual Furnace Maintenance
Furnace maintenance is extremely important, since it keeps your manufacturer warranty valid. This helps protect you if something big stops working in your furnace during your warranty period.
It can also help our professionals uncover little troubles that might make your furnace loud. And potentially help you avoid a malfunction on the coldest day of the year. The Indoor Air Quality Association reports that routine maintenance can reduce your probability of furnace repairs by up to 95%.
If little furnace problems go ignored, they can result in a malfunction later on. By discovering these issues sooner, our pros can get your furnace taken care of before heating season is underway.
And, most essential, pro cleaning and lubrication of your furnace’s moving parts 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. Routinely Replace Your Furnace’s Air Filter
Your air filter helps keep your home’s air fresh and clean. When it turns too clogged, it can make your furnace turn on and off more than it should. Called short cycling, this can cause your furnace to use extra gas and make it break down more quickly.
Our recommendations for changing your furnace filter:
- Flat filter: Once a month
- Pleated filter: Every three months
You may have to get a new filter more often if you have allergies or pets.
3. Contact Central Heating & Plumbing When Your Furnace is Producing Strange Noises
Some furnaces, especially older ones, can be noisier than others. But if you’re noticing exceedingly loud or weird noises, it may be time to get in touch with a heating and cooling company like Central Heating & Plumbing for furnace repair in New Castle.
Here are a couple of noises to keep an eye out for, how to repair them and when to call a pro.
Furnace Making Gurgling or Bubbling Noise
This noise occurs more commonly with high-efficiency furnaces. That’s since they exhaust fumes differently than older furnaces, and the process can create some moisture. If your furnace is running into difficulties removing this water, it may make gurgling or bubbling sounds. You’ll want experienced assistance for this issue, since it can be caused by a blocked drain pipe or clogged drain pan.
Furnace Making Banging Noise
It’s not a great indicator when your furnace is making a banging sound. It might mean a couple of things.
Haven’t scheduled maintenance this year and your furnace is creating a banging sound when turning on? Its burners might be dirty. Dirty burners can hold up ignition, which causes gas to accumulate inside your furnace.
All that built-up gas can make a banging or booming racket when your furnace ultimately does ignite. But this is more than merely a bothersome noise, because the accumulated gas is erupting inside your furnace. This can break your furnace’s heat exchanger and make a dangerous carbon monoxide leak.
If you’ve ignored annual maintenance for your furnace and you’re noticing this noise, give Central Heating & Plumbing a shout at 724-401-1843. Our heating specialists will get your furnace tuned up and ensure it’s working accurately.
Your ductwork can also create banging sounds when your furnace turns on, as the metal is expanding and contracting.
We recommend first inspecting your furnace’s air filter and replacing it if it’s dirty. Next, make sure you don’t have too many vents sealed in your house, as it can make air pressure uneven.
If neither of these things take care of the issue, your ductwork may be dirty or undersized, which will require assistance from a pro HVAC specialist.
Furnace Making Humming or Buzzing Noise
If your furnace is buzzing or humming, it’s a symptom there’s an electrical problem. This is most frequently seen with a faltering blower fan motor, which will produce an irritating buzzing noise when your furnace switches on. It could also mean there’s trouble with the capacitor or transformer. All three of these issues require support from an experienced heating and cooling company like Central Heating & Plumbing.
Furnace Making Knocking Noise
If your furnace is making knocking sounds, it’s frequently an indication that an internal piece is going out. This could be anything from a bearing to a belt or the gas valve. It can also be a sign that your burners need to be cleaned.
These troubles are often uncovered during regular maintenance performed by a certified HVAC technician. So, while we’re at your residence working on repairs, don’t forget to inquire about booking your maintenance appointment for the future.
Furnace Making Clicking Noise
A clicking sound can be the result of issues: worn bearings, gas valve troubles or ignition issues. All these issues call for professional help.
