Patrick Lehoski
The technician (Miko) arrived on time, was very professional and provided informative updates during the maintenance checks for both systems. He insured that all preventive measures were taken when cleaning the systems to eliminate the chance of needing unexpected cleaning of the areas. He did a great job and left after providing a complete rundown of his findings. A wonderful overall experience that was very much appreciated.
