Best General HVAC Inspections in Phoenix AZ

I've used Parker and Sons twice now for hvac maintenance with the first visit being terrific but the second left me feeling like I've been scammed. During the second visit the repair tech told me that the voltage control unit needs to be replaced and it would cost $414. Thinking that it was a control board I thought the price was reasonable but after the tech finished in 15 minutes and showed me a photo of the old and new replacement unit it looked exactly like a capacitor which cost me $60 the when I had it replaced at my old house. I called the office asking for an itemized receipt and photos of the work so that I could review the charges further but based on the uneasy feeling I have I don't think I'll be requesting further service from them in the future.
