last year my two ton house unit died so I had a friend install a new one as I dont have my own equipment (brazing tools/vacuum pump) he installed a 13 seer R22 Goodman that was working fine until fri aft when it was near 90'F outside and humid--my wife said the unit made a loud noise and the fan slowed down (probaly pulling amps) so she shut it off-two hours later when I came home I put it on again and it ran fine--but Im concerned that it doesnt happen again and I dont lose my comp--I will do an amp draw on it and check the voltage--anyone out there know what low and high psi readings I should expect on a hot day--I heard theres a concern with these units and liquid floodback-it doesnt have a suction accumulator but there is a "trap" in the piping of the suction line to the comp--anything I can do to protect my unit--would a crankcase heater help--Im new to these 13 seers----thank you

Please have your friend check the pressures, because if you ask here Beenthere will remind you of the strict no do it yourself rules..I'm just wondering where he's been, because everytime I sign on he's here...

Ya know; the term "fine" is just so damned descriptive that it really should just replace all technical terms altogether. I mean, what else do we need to know if something is "fine"?
Just about every system I have ever found to be wrongly applied, installed or otherwise not proper ran "fine" before crapping out.
The question has been asked about if the indoor unit/coil was also replaced to match the outdoor unit. We need to know the model of the outdoor unit as well as the model of the indoor coil/air handler before we can even attempt to know what could possibly be going on. Answers can never exceed the quality of a question.

inside A-coil was changed as A-coils for 13 seers are usually large or larger than the old one--not home now-later I can submit model and serial for Goodman unit=the furnace is a carrier-- more info from the wife now makes me wonder if the cond fan is the problem where I assumed it was the comp--but with equipment at work-I agree that "fine" is indeed a word describing something just before it craps out-

the best thing you can do for the unit is call in a qualified tech to check it out and set it up properly

Kinda sounds like you experienced a low voltage situation. You know the ones the power companies say they don't have. On the other hand. As a personal rule I do not like to mismatch equipment. I have found through experience that some manufacturers will make changes in capacities to prevent proper operation with other brands. If you call the service rep for goodman. He will say the problem is with the airhandler. the carrier rep will say the problem is with the condensing unit. Neither will be willimg to help. You will need a good experienced service tech. to get the mismatched system to work together.
