Here are some of the most common furnace noises and what they might be indicating. If your furnace is making an odd noise, our friendly heating specialists are here to assist with the best furnace repair in Hasbrouck Heights, New Jersey.

1. Furnace Makes Banging or Knocking Sounds

You might have a serious situation on your hands if you’re hearing your furnace making a banging noise. If your furnace is making a knocking noise, it might signal there could be a few problems. These involve gas building up in your furnace or a ductwork issue.

Banging Sounds Coming from Your Furnace

Your heating system gets grimy over time, so that’s why it’s important to set annual furnace maintenance with ACE Solutions. One of the jobs our technicians do during this work is clean your furnace’s burners. When this part gets dirty, you could hear your furnace making a loud rumbling noise when ignition takes longer than normal. The ensuing gas buildup can fracture your furnace’s heat exchanger, where natural gas turns into warmth. Any breaks in it can leak carbon monoxide, which is regularly released outside. This toxic gas can be fatal in large concentrations.

If you’re aware of banging or knocking sounds coming from your furnace, ACE Solutions recommends turning it off and calling us at 201-579-2562. Significant natural gas in your furnace or a broken heat exchanger are critical troubles that should get fast service.

Banging Sounds Coming from Your Ductwork

Your furnace relies on ductwork to provide warm air throughout your home. If the ductwork wasn’t installed right or is getting old, it can make a lot of noise when your furnace is on. This could be the case if your furnace makes a banging noise when it shuts off. Get in touch with ACE Solutions at 201-579-2562 and we’ll determine the problem.

2. Furnace Buzzes Constantly

If you notice your furnace making a buzzing noise, don’t delay calling us. A buzzing sound typically indicates an electrical situation, like with its transformer, blower motor or capacitor.

Your furnace relies on an internal transformer to operate on the right voltage. If wires or the box isn’t tight enough, you may notice a low humming noise in the furnace when off. Your furnace also uses a blower motor, which moves hot or cold air throughout your house, and a capacitor, which turns on the motor. If either of these components are going out, they will buzz when the furnace turns on.

3. Furnace Rattles

If your furnace is making a rattling noise, it can be due to something minor, like an unsecure screw, or something serious, like a broken component. In either case, we urge you to shut your furnace off and getting in touch with our heating specialists at 201-579-2562 for help.

4. Furnace Squeals

If your furnace makes a high-pitched noise, like squealing, when it’s on, it’s trying to get your attention it requires some TLC. If you’ve skipped furnace maintenance recently, belts could be worn down or a bearing may need to be lubed. We realize that maintenance often slips your mind, but our techs can get your furnace running quietly again fast.

5. Furnace Makes a Whistling Sound Like Air Escaping

When you’re hearing your furnace making a whistling noise, it’s typically because of an air leak in your ductwork. You may also notice whistling while the furnace is operating if a floor vent isn’t secure. If you’ve checked your vents but are still sensing whistling, ACE Solutions can assist you. It’s critical to get loose ductwork fixed quickly, because it can result in comfort issues in your house and drive up your gas costs.

6. Furnace Making a Grinding Noise

It’s not a good sign if you notice your furnace making a grinding noise. This metal-on-metal racket usually means there’s trouble with your furnace’s blower. Shut down your furnace off right away and contact our pros at 201-579-2562 for help.
