Very professional service on two A/C units. I suspected one unit was low on refrigerant and Clayton confirmed that. It was $105 for 1 pound of refrigerant. He replaced one of the filters and hosed out the condensing units. He also confirmed that I correctly wired my new smart thermostat.

Have installed 2 systems in the last 3 months, both replaced A/C & Heat systems were over 20 years old... I appreciate the consultive and honest approach Alex brought. Once we made the decision, we have been pleased with the install and results! Highly recommend!
