When I bought this house it had hvac installed. The ac leaked and the duct work was so corroded that most of my heat/air blew under my house rather than in it. Also, the gas furnace made me nervous having lost family to a gas furnace fire as a teen.
So I have not used the hvac for years. I have a combo heat and air unit installed through the wall and it works fine. I’m doing some underbelly work right now (repairing where previous owners had blown insulation overloaded into the belly) and I’m wondering how difficult it would be to remove the units and ductwork. I’m not using them anyway so they’re basically just in the way.
