I had AC problems, called 2 other places, one wanted to replace the entire unit the other would try to repair but couldnt guarantee it would work but it would of been a costly gamble.My daughter knew one of the service technicans at Ralphs(Gavin) and he came out listened to us regarding the problem checked the unit and did the needed repairs and saved us a whole lot of money.I would highly recommend Ralphs for repairs A++++++ Service , Honesty, Integrity
