“We recently had our heat pump and gas furnace hvac systems replaced with a geothermal system that was installed by Design Flow. We couldn't be happier with the project from start to finish. It was a big project with a lot of moving pieces and parts, but it all came together seamlessly. Brian (owner) spent a tremendous amount of time upfront discussing our options when our heat pump went up. He answered all of our questions and helped us in evaluating the pros/cons of continuing to use traditional hvac systems vs switching to geothermal. He also helped guide us through a few other decision points as we additionally had a hot water heater, humidifier and air scrubber installed as well. Michelle (project manager) ensured that all of the logistics were handled and that we knew exactly what to expect as we moved through the process. She was very patient, thorough and communicative throughout the entire project. Hunter and Mike (installers) did an amazing job! They hustled the entire time that they were here, making sure we always knew where things were when they were leaving for the day and what we could expect next. Our new system looks and runs great and we couldn't be happier – we highly recommend Design Flow for all of your hvac needs! We also recommend them if you need your hot water heater replaced – they not only installed a drain pan that dumps into our sump pump in case of a leak, but also a wet switch to detect and alert us to a leak – brilliant!”
