For this job, I completed a tune-up on the heat pump system. I went through all the mechanical and electrical parts of the system and checked for maximum efficiency. Filter was replaced and outside condenser was washed as requested by customer. Customer ask for a pen strip to be added to her indoor unit and a UV bulb was recommended by technician, and customer accepted. Cooling and heating were inspected, Thank you for choosing Comfort Experts, have a great day!
