Dave Root-Heating & Air Conditioning

May 2022

Dave and his associate Cameron are absolutely fantastic. They're professional, on-time, prompt, kind, courteous, extremely forthright with the work they're doing, and after servicing our 22-year-old unit, our HVAC has never run better. Seriously, the unit is so clean you could literally eat off it. If you're in the Grass Valley area, and are in need of HVAC service/maintenance this is the company you want. Thanks for everything, Dave and Cameron! We're life-long customers now!

Again, Dave came to my rescue. Our heater stopped working just three days after Christmas during a real chilly period. I called him for help and he was in the neighborhood, then he stopped by to help troubleshoot our problem. He even had the needed part in stock for my 30 year old unit. After I installed the part, he coached me over the phone to resove my final problem. And viola, heat again. Can't say enough his about him, his excellent service and 42 years of experience and expertise. He's done it all and knows just what to do.
