I've read a bunch here as I try to know what to ask for in a quote for a
AC system replacement. One concern about latest quote though.
The company wants to remove existing air handler and plenums and raise
them higher. This requires them to cut off the hard duct lines and replace
them with flex duct. They said they use an R8 duct and a 1" larger (than existing)
flex duct to connect rest of hard duct to the plenum. Also, they would have to
remove about 10 or more feet of return air hard duct as it is in the space above the
air handler to allow the raising.
I'm concerned that I'm losing (some of) the hard ducts. Should I be ?
[The company did measure and evaluate the house for Btu requirements, so they
did more than other contractors that just want to swap out the air handler and coil and leave the existing plenums...
