Denis arrived on time and was very professional. He was very knowledgeable and explained what he was doing. I had a A/C Tuneup performed so that I know my unit was running at peak performance and clean. He ran a lot of diagnostic tests and checked everything. He did not clean my evaporator coil, as I would have liked, because it was too difficult to get to. I was told my system is in good running condition.
