I want to thank Patrick for walking me through every step as he diagnosed my furnace problem today. This is the second time I have watched him work and both times he was able to fix the issue in a timely manner. He's one of those guys you feel you have known all your life. Thanks Patrick! Excellent work. Again.

Very happy with the AC unit they installed. Unlike other HVAC contractors in the area, Scott worked with me and was willing to listen to my comments and suggestions. It took a while to get the exact Heil unit I wanted and the install wenr well. Budget-willing, I'll be looking to them to replace my second AC unit next year.

Dekalb Mechanical updated our entire system in our home. Now it's running as quiet and efficient as ever. Installers were courteous, quick and made sure to explain the new setup before they left. No traces that they were even in my home besides the new furnace.
