We are a new customer with X-Treme. Our A/C had no cooling capability. The technician (Andrew) arrived on time, was very professional. He checked the complete system for general condition. Our system clearly has a leak somewhere. He injected a UV tracer dye into the system and added refrigerant. We are happy we are getting cold air again but we have to wait for the dye to leak out enough to detect the leak. So we are not over but have a good start. I didn't rate the cost as I have no idea what is low or high. My guess the price was fair (as in reasonable).
