We have been using One hour for several years. I believe that since 2014, Alex has been our technician...He has been the best! His customer service is top notch! We were introduced to the Home Comfort Warrantee plan,(probably 2012) Alex continues to inform us of the benefits of maintaining the "warrantee"...always an excellent job explaining it. . and it has proved to be most beneficial... we continue to tell friends and neighbors about this program. It takes the worry away! Alex is an compliment to One Hour... look forward to seeing him in the Fall for the furnace check up.. We have also taken out the plumbing maintenance program.
