When your furnace is running like it should, it should deliver warm air without making too much noise. While it’s normal to catch your furnace making noise as it starts up, other noises are indicating your furnace should get immediate professional support.

Here are some of the most frequent furnace noises and what they could mean. If your furnace is making a weird noise, our friendly heating specialists are here to fix the problem with the best furnace repair in Litchfield Park, Arizona.

1. Furnace Making a Banging Noise

You may have a critical situation on your hands if you’re detecting your furnace making a banging noise. If your furnace is making a knocking noise, it may mean there could be several problems. These include gas increasing in your furnace or a ductwork situation.

Banging Sounds Coming from Your Furnace

Your heating system becomes filthy as time passes, so that’s why it’s important to set seasonal furnace maintenance with Cooler Tymes LLC. One of the things our pros do during this work is clean your furnace’s burners. When this part gets grubby, you could hear your furnace making a loud rumbling noise after ignition takes longer than normal. The ensuing gas buildup might fracture your furnace’s heat exchanger, where natural gas turns into warm air. Any cracks in it can emit carbon monoxide, which is ordinarily emitted outside. This toxic gas can be fatal in large concentrations.

If you’re hearing banging or knocking sounds coming from your furnace, Cooler Tymes LLC recommends turning it off and reaching us at 623-208-6444. Significant natural gas in your furnace or a ruptured heat exchanger are hazardous troubles that require fast service.

Banging Sounds Coming from Your Ductwork

Your furnace uses ductwork to move hot air around your house. If the ductwork wasn’t designed correctly or is getting old, it can make a lot of noise when your furnace runs. This can be the issue if your furnace makes a banging noise when it shuts off. Call Cooler Tymes LLC at 623-208-6444 and we’ll pinpoint the problem.

2. Furnace Buzzes Constantly

If you hear your furnace making a buzzing noise, don’t wait to call us. A buzzing sound often means there’s an electrical problem, like with its transformer, blower motor or capacitor.

Your furnace depends on an internal transformer to work on the correct voltage. If wires or the box is loose, you may notice a low humming noise in the furnace when off. Your furnace also works with a blower motor, which sends warm or cooled air across your rooms, and a capacitor, which turns on the motor. If either of these components are going out, they will buzz when the furnace starts.

3. Furnace Rattles

If your furnace is making a rattling noise, it can be related to something minor, like an unfastened screw, or something serious, like a broken component. In either case, we urge you to shut your furnace off and contacting our heating professionals at 623-208-6444 for support.

4. Furnace Is Making a High-Pitched Squealing Sound

If your furnace makes a high-pitched noise, like squealing, when it’s running, it’s making an effort to tell you it needs some TLC. If you’ve neglected furnace maintenance recently, belts could be worn out or a bearing may need to be greased. We realize that maintenance frequently slips your mind, but our professionals can get your furnace heating quietly again rapidly.

5. Furnace Makes a Whistling Sound Like Air Escaping

When you’re hearing your furnace making a whistling noise, it’s typically due to an air leak in your ductwork. You may also notice whistling while the furnace is running if a floor vent isn’t tight. If you’ve checked your vents but are still hearing whistling, Cooler Tymes LLC can provide support. It’s critical to get loose ductwork taken care of without delay, because it can result in comfort issues in your residence and increase your energy costs.

6. Furnace Makes a Loud, Unpleasant Grinding Noise

It’s not a positive sign if you hear your furnace making a grinding noise. This metal-on-metal sound usually means there’s trouble with your furnace’s blower. Switch off your furnace off now and contact us at 623-208-6444 for support.
