[DML] Re: Air Conditioning

["David Teitelbaum" <jtrealty@xxxxxxxxxxx>]

It seems some people DO read my posts! I meant to say 90, not 80 so
90-70 DOES equal a delta T of 20. In any case you want to see a
temperature differential across the evaporator coil of 20 degrees. It
doesn't matter exactly what the temp going in is as long as the temp
coming out is 20 degrees less. At least as long as it stays above 34
or so. Any lower and the evap coil will freeze up. Easily checked with
a thermometer. If you cannot achieve a 20 degree delta T either a coil
is not getting enough airflow (heat transfer) or you do not have a
correct charge of refrigerent. Other things can also cause a lack of
cooling capacity but these are the most common reasons.


the air going in to the A/C is 80 it should come out around
> 70. You should also hear the compressor cycle often.
