I have been a customer at Central Cooling since the end of 1996 or beginning of 1997 at a different home. Here I inherited an old system that was replaced in 2016 by Central Cooling because they always have done excellent reliable work. Unfortunately due to a bad storm with high winds, a problem was discovered during a regular semi-annual check-up which required a second visit by a different technician, Vlas Kuchar. An extensive amount of work was necessary which was a nearly four hour stint in the freezing cold, but knowing Central Cooling's policy of hiring the best, I am assured of heat for the rest of the winter. I want to thank Vlas for his tenacity and willingness to stick with this project on a freezing day on the roof.
