Hopefully someone can help me troubleshoot my problem. My Carrier unit runs all the time during the day and sometimes falls behind keeping up with the set point on my T-Stat.
Details listed below:
4 Ton Single Zone System made by Carrier and installed in 1996
Single Family Home 1975 Sq Ft two story cathedral ceilings
Todays Readings at 5:00 PM
Oustide Air Temp 80 Degrees
Suction Temp At Condenser 59.2 Degrees
High SideTemp At Condenser 83.8 Degrees
Suction Pressure 66 psi.
High Side Pressure 255 psi.
I calculate my superheat at 20 Degrees
This evening my return temp at the return grill was 64 degrees and the supply temp at a register was 56 degrees. Only 8 degrees differential
Is this unit low on Freon? Or is there something else going on?
Any help would be greatly appreciated.
