Coolray installed 2 new HVAC units in 2006 and have had them do preventive maintenance (PM) since that time. All of the techs have been first class. For the past 2-3 years Jorge Valencia has done our PM. He is outstanding. He is very professional, courteous and friendly. If there is a problem he explains everything to me and tells me what my options are. Last summer the upstairs unit would not cool. A tech came out and replaced a circuit board with absolutely no charge to me.
