I don’t know what it was, but my ductwork system kept having issues.
It was always developing leaks and then it was worse when an HVAC expert discovered mold growing inside.
I can’t tell you how many times I had to have the ductwork cleaned and resealed. Then another HVAC worker was talking about replacing a whole section of ductwork which was going to cost me a small fortune. I ended up calling another HVAC company to see what options they could give me. This HVAC expert who came out was actually really nice and had good news for me for a change. Since my HVAC system was very old, around 14 years and was on its way out, he suggested that I go for a ductless HVAC system. I honestly never even knew they had ductless HVAC systems on the market. I had a hard time understanding how that would even work, but the HVAC expert explained it all to me. Basically you’ll have an outdoor condenser unit connected to line sets that hook up to the different indoor units. This system uses refrigerant to spread the heating energy. It’s basically a heat pump so you can push the heating out of the house for a cooling effect, and vice versa. The whole idea of not having to mess with that ancient ductwork made me feel happy, like a huge relief in my mind. I went for this installation and I have been happy ever since. We have had smooth operation of the new ductless HVAC with no issues whatsoever. Of course, we get regular HVAC maintenance as we are on an HVAC service plan.
