I was very much impressed with Mike's service visit. He not only performed required services, he investigated the condition of the AC coil and suggested a thorough cleaning. I have had a GVC&H contract since 1993 and this was the first time I have ever seen this the chamber opened exposing the dirty environment. Further, he provided other simple homeowner tips e.g. washing down heat exchanger with garden hose. All in all it was an exceptional performance by a highly qualified, knowledgeable and helpful technician.
