Dyllan and John from X-treme just left after completing an evaporator coil replacement. I was extremely (no pun intended) impressed with their professionalism, cleanliness and knowledge. I've found it rare to experience this level of service and I tend to be a hard marker. Cost: The cost was fair. Its a little difficult in this economic market to really know gauge the cost. However I will say that I will without hesitation call on X-treme for any A/C issues. I also plan on using them for my heating as well.
