I had Total Air come out to do a diagnostic on my A/C unit and was quoted $79.00. When the technician arrived he look at both inside and out units and determined it was the condenser and memory board for my air handler. He told me I owed him $159.00. He said the $79.00 was only the trip charge and the diagnostic was separate. I reiterated I was quoted $79.00 he said he would have to talk to his office then only charged the $79.00 ad far as I know. So the quote for the capacitor and control board came to $970.60. So I ran into an A/C guy on one of my job sites and explained what I was told and he said it would be closer to $700 and could even get it lower if he bypassed the control board. He quoted me $385. I agreed and one of his technicians came out and determined there was nothing wrong with either the Control board or capacitor. Instead it was the fuse and wire touching metal that caused it to not work. The bill came in at $279 and works great both heat and cold.
