Great service and great technicians - Alberto and Victor really do know what they are doing and take their work seriously. A previous company that shall remain nameless told me two days earlier that I would need to buy a new unit. I had a gut feeling because I did not believe my issue was that serious. They quoted me a cost of replacing the unit and it was simply over the top. So I called Cal Air for a second opinion. Albert and Victor found the issue within minutes. The previous tech from that OTHER company had reversed the wiring on the capacitor. Had I turned on the air conditioner I would have burned out the fan and the compressor would have burned as well. The previous tech did not tell me I could not use the air conditioner...I just decided on my own not to turn it on. Alberto and Victor checked all systems and the unit is working better than ever! I live in Las Vegas, and one must be very careful as far as who you pick for repairs. If you are having issues with your present AC company I would not hesitate to recommend Cal Air.
