Tech arrived as scheduled after calling ahead to announce he was on his way. Cleaned A/C coils, measured freon, checked current draw, circulation fan, condensing coils, cleaned overflow line with bleach water. Went over results with owner before leaving. Installed tag on unit to indicate last service and date. Jack Frost has performed all types of A/C work for us over the years, replacing fan motors, A/C cooling units, startup capacitors. Pricing always has been reasonable. They offer a Blue Key maintenance program which gives you priority if your place a service call. Our A/C unit failed on the hottest day of the year in 2001 and they had it repaired within two hours even with a backlog of calls.
