No I was not kidding. The one that came with the coil is not necessarily the correct one.
Customer complaint: "The company that installed this system has had to add refrigerant every spring and remove refrigerant each fall. Why is my system behaving this way?"
Answer: Incorrect installation and setup.
Recent: A one and a half ton condensing unit does not need 3 tons of air. The coil was mounted on a furnace with a 3 ton blower on high. Original installers replaced 3 TXV's and one compressor in the first year.
I can't take a picture of stupidity for the wall of shame.
Every problem gives us the opportunity to choose from several solutions: stupidity, ignorance, indifference, or brilliance. Which one will you choose?
Usually for the largest size condensor that is a match for that coil.
Piston size is determined by OD unit size and SEER and refrigerant type.
Goodman has always supplied a piston chart with most replacement coils.
Most of what I work on is straight cooling.
I still have found that the chart shows the piston on the evap SOMETIMES, and SOMETIMES the one on the condenser.
AGAIN there is USUALLY only 1 number difference....
Those who dance, appear insane to those who do not hear the music.
Those who believe, appear ignorant to those who do not know God.
