I thought I was taking care of my HVAC unit.
My model was relatively new, at five years old.
I did everything right when I had it installed, hiring a licensed HVAC supplier who helped me order from his business’s catalog. We weighed the pros and cons of several systems, and studied my household to make sure that we were choosing a system that was the right fit. I’ve been calling out HVAC suppliers at least twice a year ever since it was newly installed. Now, suddenly, I am hearing some bad noises coming from the system – rattling and vibrating noises; other times, a loud, banging noise. It scares me so much that I turn off the cooling system entirely. Was this a big issue? Wondering, I called a company to see what the problem was, but long story short, there was nothing wrong with the component itself. The air duct was aging, and falling apart. It had become disjointed in several sites. Cracks were developing in others. It turns out, I needed to get the entirety of my air duct replaced. That cost a pretty penny, but it was definitely less costly than replacing the component itself! I was quite satisfied with this HVAC supplier service, particularly because my component ran quietly after the air duct was replaced. So, if you ever hear unusual noises coming from your system, it may actually well be a problem with the air duct.
