i've got a retro job that I'm finishing up, I'm coming into the job to start up the system. I'm an installer and I don't do load calcs but i'm starting to wonder if this house has the right size unit. I don't have duct sizes yet but was hoping my temps and pressures might help me figure out the problem. Basically from the home owners stand point we're barly getting warm air from the registers. I'm only getting 81 degrees out of the supply registers.
Variable speed A.H. set for 2 1/2 ton
Outdoor unit is 2 ton
I this my problem or is this regular practice?
Here is some readings that I thought could help.
