2 Stage Heat Pump questions
I got a 2 stage ICP heat pump...17.5 seer Tempstar... when it was installed they had to add some puron to it. But the compressor is 2 stage and it was charged while running on the 1st stage (low). does it matter which stage the compressor runs while it is being charged?
also, when the 2nd stage kicks in what happens? does it produce colder air? I know the fan speed is supposed to ramp up on the air handler but does the compressor make the indoor coil colder?
thanks for any info
