I read online that if your heater makes noises during operation, it is a bad sign. It could mean a system malfunction or a huge heater repair left unchecked. When I started noticing a squeaking noise when I walked by my heater, I started to get worried. I didn’t want to deal with a huge heater repair or possibly buy a new system. Everything online was all gloom and doom. I finally gritted my teeth and called my HVAC contractor. I found out a few things. First, sounds can be a bad thing. It can be parts that need lubrication and now are grinding together and creating damage. It can be something is loose, rusted or corroded inside the heater. Sounds also can be a very small hiccup in production. The furnace not properly hooked up to the ductwork makes an odd sound. A slightly dirty fan makes the heater sound weird. I also found that if the heater makes a squeak when you walk by it, the bolts are tightened too much on the system. The HVAC contractor loosened them a bit and everything was fine. He cleaned the heater while he was there, but it was a rather embarrassing HVAC appointment. Thankfully I only got charged 50 bucks since the guy had to make the drive. I now know that I need to carefully determine what the sound is and when it happens. Something huge or something very small is happening with a heater when it makes noises. I don’t want to call again for something very small and stupid.
