When your furnace is operating correctly, it should deliver warm air without generating too much disruption. While it’s normal to catch your furnace making noise as it turns on, other sounds are signaling your furnace needs immediate professional support.
Here are some of the most common furnace noises and what they might be indicating. If your furnace is making a weird noise, our friendly heating pros are here to help with the best furnace repair in Logan, UT.
1. Furnace Making a Banging Noise
You could have a serious problem on your hands if you’re noticing your furnace making a banging noise. If your furnace is making a knocking noise, it may mean there could be a couple of problems. These involve gas building up in your furnace or a ductwork problem.
Banging Sounds Coming from Your Furnace
Your heating system turns grimy over time, so that’s why it’s essential to set yearly furnace maintenance with Western Mechanical, Inc.. One of the tasks our professionals do during this work is clean your furnace’s burners. When this part gets grimy, you might hear your furnace making a loud rumbling noise when ignition takes longer than normal. The subsequent gas buildup may crack your furnace’s heat exchanger, where natural gas transforms into warm air. Any fractures in it can leak carbon monoxide, which is regularly vented outdoors. This hazardous gas can be fatal in large concentrations.
If you’re aware of banging or knocking sounds coming from your furnace, Western Mechanical, Inc. recommends turning it off and contacting us at 435-753-5515. Excessive natural gas in your furnace or a fractured heat exchanger are hazardous problems that require immediate service.
Banging Sounds Coming from Your Ductwork
Your furnace relies on ductwork to deliver heated air across your house. If the ductwork wasn’t put in properly or is aging, it can be loud when your furnace is heating. This could be the case if your furnace makes a banging noise when it shuts off. Contact Western Mechanical, Inc. at 435-753-5515 and we’ll pinpoint the problem.
2. Furnace Making a Buzzing Noise
If you observe your furnace making a buzzing noise, don’t delay calling us. A buzzing sound typically is telling you there’s an electrical issue, like with its transformer, blower motor or capacitor.
Your furnace relies on an internal transformer to work on the proper voltage. If wires or the box is loose, you could detect a low humming noise in the furnace when off. Your furnace also uses a blower motor, which moves warm or chilly air around your house, and a capacitor, which triggers the motor. If either of these components are going out, they will buzz when the furnace turns on.
3. Furnace Making a Rattling Noise
If your furnace is making a rattling noise, it can be due to something little, like a loose screw, or something major, like a broken component. In either case, we recommend shutting off your furnace and getting in touch with our heating professionals at 435-753-5515 for help.
4. Furnace Making a Squealing Noise
If your furnace makes a high-pitched noise, like squealing, when it’s on, it’s attempting to get your attention it needs some TLC. If you’ve forgotten furnace maintenance recently, belts could be worn out or a bearing might need to be lubed. We know that maintenance sometimes slips your mind, but our technicians can get your furnace heating quietly again fast.
5. Furnace Making a Whistling Noise
When you’re hearing your furnace making a whistling noise, it’s typically because of an air leak in your ductwork. You might also hear whistling while the furnace is working if a floor vent is loose. If you’ve checked your vents but are still hearing noise, Western Mechanical, Inc. can assist you. It’s essential to get loose ductwork repaired quickly, because it can make comfort issues in your home and drive up your gas costs.
6. Furnace Making a Grinding Noise
It’s not an encouraging sign if you hear your furnace making a grinding noise. This metal-on-metal racket often means there’s an issue with your furnace’s blower. Switch off your furnace off now and call our professionals at 435-753-5515 for assistance.
