Hands down one of the best HVAC companies I've worked with. They take care of multiple properties for me and are always on point — quick response, fair, and quality work every time. If you're looking for a company you don't have to worry about, this is it.

Without a doubt, Design has gone above and beyond. From the start, they've been incredibly professional, patient, and truly invested in helping diagnose recurring issues with my AC and furnace. It's rare to find a company that feels more like a partner than a service provider. A special shoutout to Tim Schmitt, who has spent over 10 hours at my home diagnosing a heating issue.

Amazing group of people! Aaron G., Tim and Alex have been a Godsend in assisting me with my new home. Design did an excellent job installing everything, and has been gracious in helping resolve issues they didn't cause.

Design changed out our heater and AC. Caleb and his partner did an outstanding job. They found some mold in the heat exchanger from the humidifier, resealed the humidifier and fixed the leak. I was very impressed with Design!Furnace + AC change‑out
