5 ton kws
Did a power consumption reading on a 5 ton, single phase, A/C unit and the total power consumption for the Evap and condenser was 4.36kw. Is this reading normal?

Re: 5 ton kws
Sounds about right - the unit is probably not running at design full load. The numbers are about where we would expect them to be with the unit running say 70 to 80% Loaded - meaning the return air and outdoor air enthalpy's are low enough to, in a combined fashion, amount to less that full design load conditions.
