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. In the indoor unit, system had a lot of biological growth however customer was aware and was not interested on any possible solution to remove that. In the outside unit, the fan was not running, I checked the capacitor and it was out of tolerance, capacitor was replaced and everything was functioning like normal. Thank you for choosing Comfort Experts, have a great day!
