For the job, I worked on a super tune-up on this heat pump system. I went through all the mechanical and electrical part of the system, unchecked for maximum efficiency. When going through the system, I noticed the compressor over amping, this was notified to the customer and I recommended her to add something to help her compressor out, customer said that she will talk to her husband and think about it. Other than that her system was washed and was left running and in great condition. Thank you for choosing Comfort Experts, have a great day!
