Todd installed geothermal system and ducting in new home build 2011. Very knowledgeable, friendly, upfront and honest. System works great and saves a lot on electric. He configured our system to preheat our hot water before going to tankless water heaters which decreases their workload. Does our annual maintenance and only had one repair needed (10/2017, capacitor replacement) under warranty. Was prompt with the diagnosis and repair despite travel distance. Very knowledgeable with geothermal system.
