When your furnace is running properly, it should give heat without generating too much disruption. While it’s common to hear your furnace making noise as it begins running, other disruptions are indicating your furnace needs immediate professional assistance.
Here are some of the most reported furnace noises and what they could mean. If your furnace is making an odd noise, our friendly heating professionals are here to fix the problem with the best furnace repair in Philadelphia, Pennslyvania.
1. Furnace Makes a Banging Sound
You might have a critical problem on your hands if you’re hearing your furnace making a banging noise. If your furnace is making a knocking noise, it may mean there could be several problems. These involve gas increasing in your furnace or a ductwork situation.
Banging Sounds Coming from Your Furnace
Your heating system gets grimy over the years, so that’s why it’s critical to set yearly furnace maintenance with Retro HVAC Service & Installation. One of the tasks our professionals complete during this appointment is clean your furnace’s burners. When this part gets grimy, you may hear your furnace making a loud rumbling noise if ignition takes longer than normal. The resulting gas buildup may break your furnace’s heat exchanger, where natural gas changes into warmth. Any breaks in it can discharge carbon monoxide, which is normally released outside. This toxic gas can be deadly in large concentrations.
If you’re aware of banging or knocking sounds coming from your furnace, Retro HVAC Service & Installation advises turning it off and calling us at 267-277-3851. Too much natural gas in your furnace or a ruptured heat exchanger are dangerous troubles that require prompt service.
Banging Sounds Coming from Your Ductwork
Your furnace uses ductwork to provide heated air across your house. If the ductwork wasn’t put in right or is getting dated, it can be loud when your furnace runs. This might be the problem if your furnace makes a banging noise when it shuts off. Contact Retro HVAC Service & Installation at 267-277-3851 and we’ll pinpoint the problem.
2. Furnace Makes a Buzzing Sound
If you hear your furnace making a buzzing noise, don’t wait to call us. A buzzing sound often is telling you there’s an electrical issue, like with its transformer, blower motor or capacitor.
Your furnace uses an internal transformer to operate 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 uses a blower motor, which distributes hot or cold air throughout your residence, and a capacitor, which turns on the motor. If either of these parts are going out, they will buzz when the furnace starts.
3. Furnace Makes Rattling Sounds Like Something Is Loose
If your furnace is making a rattling noise, it could be the result of something minor, like a loose screw, or something critical, like a broken piece. In either case, we urge you to shut your furnace off and getting in touch with our heating specialists at 267-277-3851 for help.
4. Furnace Is Making a High-Pitched Squealing Sound
If your furnace makes a high-pitched noise, like squealing, when it’s on, it’s trying to get your attention it could use some TLC. If you’ve forgotten furnace maintenance recently, belts could be worn down or a bearing may need to be lubed. We are aware that maintenance sometimes slips your mind, but our professionals can get your furnace running quietly again rapidly.
5. Furnace Making a Whistling Noise
When you’re hearing your furnace making a whistling noise, it’s typically due to an air leak in your ductwork. You could also notice whistling while the furnace is on if a floor vent isn’t tight. If you’ve looked at your vents but are still hearing sound, Retro HVAC Service & Installation can provide support. It’s essential to get loose ductwork fixed quickly, as it can create comfort troubles in your house and increase your energy bills.
6. Furnace Making a Grinding Noise
It’s not a positive sign if you notice your furnace making a grinding noise. This metal-on-metal noise often means there’s an issue with your furnace’s blower. Shut down your furnace off promptly and reach our pros at 267-277-3851 for help.
