Here are some of the most frequent furnace noises and what they could be signaling. If your furnace is making a strange noise, our friendly heating specialists are here to help with the best furnace repair in Safford, Arizona.

1. Furnace Makes Banging or Knocking Sounds

You might have an urgent situation on your hands if you’re noticing your furnace making a banging noise. If your furnace is making a knocking noise, it may indicate there could be a few problems. These involve gas building up in your furnace or a ductwork situation.

Banging Sounds Coming from Your Furnace

Your heating system gets dirty over the years, so that’s why it’s essential to schedule seasonal furnace maintenance with B&D Air Conditioning. One of the tasks our techs complete 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 is delayed. The ensuing gas buildup may fracture your furnace’s heat exchanger, where natural gas turns into warm air. Any breaks in it can leak carbon monoxide, which is ordinarily released outdoors. This toxic gas can be deadly in large concentrations.

If you’re hearing banging or knocking sounds coming from your furnace, B&D Air Conditioning recommends turning it off and contacting us at 928-432-6018. Too much natural gas in your furnace or a broken heat exchanger are hazardous troubles that require prompt repairs.

Banging Sounds Coming from Your Ductwork

Your furnace uses ductwork to provide hot air across your house. If the ductwork wasn’t put in correctly or is getting old, it can be loud when your furnace runs. This may be the issue if your furnace makes a banging noise when it shuts off. Contact B&D Air Conditioning at 928-432-6018 and we’ll figure out the problem.

2. Furnace Buzzes Constantly

If you notice your furnace making a buzzing noise, don’t wait to call us. A buzzing sound frequently 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 right voltage. If wires or the box needs to be tightened, you might hear a low humming noise in the furnace when off. Your furnace also has a blower motor, which distributes hot or chilly air around your space, and a capacitor, which starts the motor. If either of these parts are fading, 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 small, like an unfastened screw, or something serious, like a broken piece. In either case, we recommend shutting off your furnace and contacting our heating pros at 928-432-6018 for help.

4. Furnace Making a Squealing Noise

If your furnace makes a high-pitched noise, like squealing, when it’s going, it’s trying to get your attention it requires some TLC. If you’ve neglected furnace maintenance the past few years, belts could be worn down or a bearing may need to be lubed. We realize that maintenance sometimes slips your mind, but our pros can get your furnace operating quietly again quickly.

5. Furnace Whistles

When you’re detecting your furnace making a whistling noise, it’s typically the result of an air leak in your ductwork. You could 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 noise, B&D Air Conditioning can help. It’s essential to get loose ductwork repaired fast, as it can make comfort issues in your residence and inflate your energy costs.

6. Furnace Making a Grinding Noise

It’s not a good sign if you detect your furnace making a grinding noise. This metal-on-metal sound typically means there’s an issue with your furnace’s blower. Turn off your furnace off right away and reach us at 928-432-6018 for support.
