Our tech, Larry Reit, did a fantastic job. He answered numerous emails, patiently guiding us through a troubleshoot of our unit. When our electrician arrived to assist us, Larry called and explained carefully and clearly how to check the voltages, safety switches and door switches. With his help, our unit is running better than ever. We are truly grateful for his expertise, patience and courtesy. Larry made all the difference in our tech support experience. We will certainly recommend this company to everyone. Thanks Larry!
