I recently had a new heat pump system installed to replace an old 2 ton system which on the hottest days of the year could hold indoor 77 deg F with low humidity.
By accident the contractor installed a 2.5 ton Compressor and AHU - which I am concerned will cycle more often than a 2 ton system.
In fact the only time it runs for more than 20 minutes is when it's over 90 degrees outside by keeping indoor at 75F.
The contractor has being very nice about it and has offered to redo the entire system if needed but would like to try first replacing one component to a 2 ton size.
So, my question is which makes more sense as a first try - outside 2 ton, inside 2.5 ton or outside 2.5 ton, inside 2.0 ton?
Lennox specs say either arrangement is a proper match. Will a 2.5 ton AHU matched to a 2 ton compressor operate at a higher indoor coil temp and not dehumidify as well?
Lennox XP17 single stage scroll compressor. 2.5 ton AHU is one speed set to lowest speed and is probably putting out around 950CFM, higher than old system.
