For this job, I worked on a super tune-up on this heat pump system. I went through all the mechanical and electrical parts of the system and checked for maximum efficiency. As I was talking to the customer, he mentioned he was interested in a compressor saver, I presented the compressor saver and customer approved. Compressor saver was added to the system, and tests were shown to the customer. Thank you for choosing Comfort Experts, have a great day!
