Payne AC unit not blowing cool air... Also, fan not spinning on outside unit. Is there a reset button or a way to check the power for the outside unit? Please help. Heat wave in California :/

I was quoted 5800 to replace roof top a\c with a payne 3 1/2 ton package unit scroll comp. what I am asking is this a fair price and is the unit trouble free, I'm replacing a wards unit that was installed in 1972 about 10 years ago replaced gas valve now it leaked out the freon but still runs other...

Have a 2 yr old 90% efficiency unit.Getting code 33 while the blower runs and then code 13 when it's off. Limit switch suppose to reset in 3 hrs but has not. Flame rollout switch is not tripped so can't manually reset. This prob came about from not changing filter soon enough.

I want to know which is the best to use for a Seminar Room. The package unit or an AHU with condensing unit.

My Mother just had a Trane 15 seer Package unit installed. She told me she was having some problems with it and asked if I would come and look at it. The installer was acting very professional. This is the problem. The condensation line comes out and makes a 90 degree turn and runs about 3 feet....
