Upon my arrival I performed a 6 month checkup on 1 straight cool furnace system and 1 mini split heat pump system. Flushed and treated water removal systems, washed condenser coils using water, cleaned and treated electrical cabinets then verified system safety and performance. I found both systems operating to manufacture specifications at this time. Customer is going to talk to his wife to see how they would like to move forward on the maintenance plan and will contact the office when they make a decision.
