Customer Reviews

“Design Flow was top-notch from start to finish — from our very first conversation about adding central air to our home, all the way through scheduling and installation. Brian came out to evaluate our needs and walk us through the various system options available. We received four (FOUR!) detailed proposals promptly, each outlining different equipment and configurations, and every question we had about the systems and installation process was answered thoroughly and without delay.

Communication throughout the entire process was outstanding —From Michelle, the office manager who expertly coordinated the installation, to Brian, Hunter, and the rest of the skilled technicians who executed the work. Since our home had no existing ductwork, this was far from a simple upgrade, but the installation team handled every challenge with skill, professionalism, and respect for our home. They worked efficiently and seamlessly, even when unexpected issues arose.

We especially appreciated the care the team took in treating our home respectfully, leaving no mess behind. The technicians were knowledgeable and patient, answering all of our questions and providing an in-depth walk-through at the end of the installation. They took the time to explain how the new system operates, including the thermostats and zone programming, ensuring we felt completely comfortable with everything before they left.

We look forward to relying on the Design Flow team for routine servicing and maintenance of our new system as needed.”

“Techs arrived promptly for my first service since moving to the area. I like dealing with a small shop where customer service is important.
They performed all the items in the maintenance as well as replacing a soon to fail capacitor which did not read in the proper range. Techs were friendly, neat, and helpful in explaining my unit, which came with the home. They were able to provide me with details about this system and insights into a few problems which they corrected. I appreciated their knowledge and expertise. I'm glad I chose Design Flow to service my heat pump.”
