Is it a problem to have a mismatched indoor and outdoor components?
Specifically, I have two systems with the following:
Heat Pump-Goodman GSH130301AA (2-1/2 ton)
Air Handler-Goodman ARUF364216AA (3 to 4 ton capacity)
this cools/heats 1100 sq.ft. 2nd level with 151 sq.ft. of windows
Heat Pump-Goodman GSH130421AA (3-1/2 ton)
Coil-Goodman CAPF4860D6AA (4 to 5 ton capacity)
Furnace- Goodman GMS91155DXAA
this cools/heats two levels:
main level of 2100 sq.ft. with 448 sq.ft. of winows and
lower level of 1600 sq.ft. with 240 sq.ft. of windows
I am having cooling problems because I think the system is undersized for our square footage and the number of windows, but I wanted to know if a below capacity range heat pump is generally acceptable or contraindicated.
