I heard from a friend of mine that if your heating system makes sounds, you are basically screwedâ€¦ A noisy heating system indicates that something is grinding together & will be a giant gas furnace repairâ€¦ Of course, my heating device started making some noise & I freaked out, then thankfully I did not call the local Heating & A/C company instantlyâ€¦ I decided to do a little research online, then noises can be a immense deal, however most of the time are just a small fix.
If your Heating & A/C device is making a whistling noise, it could be something as self-explanatory as a gap in the HVAC duct.
The HVAC duct connecting to the oil furnace could have a small gap that allows the air to whistle through. A little taping around the HVAC duct & the concern is solved. If the oil furnace is making a loud banging noise, it could be the squirrel cage not properly securedâ€¦ You can bolt it down or just put styrofoam underneath the whole heating equipment. The sound is then gone. If the heating device makes a squeak every time you walk by, that is the bolts on the heating element. It means they are a bit tight, and just loosen them & all is good; What I had to do was screw my bolts in a little tighter. The noise from my gas furnace went away & it seems to be good now. I suppose a Heating & A/C company would have charged me a ton for just a self-explanatory fixâ€¦ Good thing I did a little research before I paid for it.
