When your furnace is running correctly, it should give warmth without generating too much sound. While it’s expected to hear your furnace making noise as it starts up, other sounds are indicating your furnace should get immediate professional assistance.

Here are some of the most reported furnace noises and what they could be indicating. If your furnace is making an odd noise, our friendly heating professionals are here to assist with the best furnace repair in Litchfield Park, Arizona.

1. Furnace Makes a Banging Sound

You could have a serious situation on your hands if you’re noticing your furnace making a banging noise. If your furnace is making a knocking noise, it might mean there could be several problems. These involve gas accumulating in your furnace or a ductwork problem.

Banging Sounds Coming from Your Furnace

Your heating system gets grimy as time passes, so that’s why it’s critical to schedule yearly furnace maintenance with Cooler Tymes LLC. One of the things our professionals complete during this service is clean your furnace’s burners. When this part gets grimy, you could hear your furnace making a loud rumbling noise after ignition is delayed. The ensuing gas buildup may crack your furnace’s heat exchanger, where natural gas transforms into warm air. Any breaks in it can discharge carbon monoxide, which is normally emitted away from your home. This dangerous gas can be lethal in large concentrations.

If you’re aware of banging or knocking sounds coming from your furnace, Cooler Tymes LLC recommends turning it off and contacting us at 623-208-6444. Excessive natural gas in your furnace or a broken heat exchanger are hazardous problems that require immediate repairs.

Banging Sounds Coming from Your Ductwork

Your furnace works with ductwork to move warm air around your house. If the ductwork wasn’t installed properly or is getting dated, it can be noisy when your furnace is on. This might be the problem if your furnace makes a banging noise when it shuts off. Contact Cooler Tymes LLC at 623-208-6444 and we’ll figure out the problem.

2. Furnace Makes a Buzzing Sound

If you hear your furnace making a buzzing noise, don’t hesitate to call us. A buzzing sound usually indicates an electrical issue, like with its transformer, blower motor or capacitor.

Your furnace relies on an internal transformer to run on the correct voltage. If wires or the box isn’t tight enough, you might hear a low humming noise in the furnace when off. Your furnace also uses a blower motor, which sends warm or cold air throughout your house, and a capacitor, which triggers the motor. If either of these pieces are failing, they will buzz when the furnace switches on.

3. Furnace Makes Rattling Sounds Like Something Is Loose

If your furnace is making a rattling noise, it can be the result of something little, like an unsecure screw, or something critical, like a broken piece. In either case, we recommend shutting off your furnace and contacting our heating professionals at 623-208-6444 for support.

4. Furnace Making a Squealing Noise

If your furnace makes a high-pitched noise, like squealing, when it’s going, it’s making an effort to tell you it needs some TLC. If you’ve skipped furnace maintenance recently, belts could be worn down or a bearing might need to be greased. We realize that maintenance sometimes slips your mind, but our techs can get your furnace operating quietly again rapidly.

5. Furnace Making a Whistling Noise

When you’re noticing your furnace making a whistling noise, it’s typically the result of an air leak in your ductwork. You may also be aware of whistling while the furnace is running if a floor vent isn’t secure. If you’ve examined your vents but are still noticing noise, Cooler Tymes LLC can assist you. It’s critical to get loose ductwork fixed without delay, as it can create comfort problems in your house and drive up your energy costs.

6. Furnace Makes a Loud, Unpleasant Grinding Noise

It’s not an encouraging sign if you notice your furnace making a grinding noise. This metal-on-metal sound frequently means there’s trouble with your furnace’s blower. Turn off your furnace off promptly and contact our professionals at 623-208-6444 for assistance.
