I installed a new Am. standard 2 ton 410A system, single stage 65k BTU firnace and cased txv coil. It runs non stop and rarely satisfies the stat on a 975 sf ranch home with no basement. Check out these measurements, any clues?
Ambient air temp: 99 deg
Suction 150 PSIG. 68 degrees with 13 degree superheat
Liquid 377 PSIG. 101 degrees with 12 degree subcool
Compressor drawing 13 amps
Dry bulb temps: return 77.6 deg
Supply 61.8 deg
Wet bulb temps: return 68.5 deg
Supply 61.3 deg (all averages!)
What the heck am I missing?! Is there WAY less insulation in the walls or is this unit just not producing?? Oh, and these temps are with the fan speed set to LOW! Replaced the TXV and factory said we are moving too much air over the coil lol!? Really? Too much return air? Any help will be greatly appreciated!
