Chris Dehnart did an excellent job. Very professional, explained everything very well as to what he was doing, and explaining what could happen in the future, and heads up on pricing so I had and idea of what to expect in the event of the A-Coil needing replaced. Sold me well on the 1 year service plan, with the discounts, and use of it in the future. Covered his shoes to keep the floor clean, and very professional with his work.
