“I have been using Design Flow for over a decade. They are friendly, efficient, and professional. Not only do they rank excellent in their expertise, their costs are very reasonable. I’ve had my heating and air conditioning replaced by them. I maintain their yearly maintenance contract with them. Recently, Sammy came out to do the Spring maintenance. It was near the end of the day; however, he did not rush, took his time, cleaned out my outside air conditioning unit of every leaf and debris blown into it (did an amazing job; looks brand new). I couldn’t been more pleased.
I recommend Design Flow to everyone!”

“Did a great job to diagnose the issue and was able to get our heat back on. Cody was very knowledgeable and polite. Would use your company again.”

“After dealing with several random HVAC issues, Design Flow figured out that our heat pump was functioning properly, but the air flow in the house was not. To resolve the issue and help to keep the heat from escaping, we had our crawl space duct work wrapped and flexible vents replaced to bring them up to code. The other replacement involved creating a new plenem off the top of the heat pump to direct the air flow down the ducts. The current plenum causes the air to hit the top of it and then make a right angle before flowing down the ducts. This is where Brian, the owner of Design Flow, puts his designing skills to work. He created the new phlenem out of sheet metal with curved baffles inside that allow the supply air to flow out of the heat pump and send it directly throughout the house. Another adjustment involved removing a 2nd vent line to the kitchen that was installed right off the plenem – this removal has allowed more air to reach the rest of the house and allows our system to work more efficiently. Mike & Hunter, who made the adjustments were great. Their work skills are excellent, and they left the place as clean as they found it. Thank you Design Flow!!”

“Very organized. Cody was a delight to work with. He did an excellent job and completely cleaned up after himself.”

“Our Oil Furnace was struggling and needed service during these cold days in January. I called and they were out the next day. It wasn't an emergency, so that was fine. Sammy a technician that has been with Design Flow since 2018 came out and spent several hours not only fixing, but doing a full maintenance on our furnace. He explained everything he was doing and we even save money by getting the maintenance package. This is the second time using them. The first was for my mom's condo prior to selling. Everyone is honest and does a great job. I highly recommend Design Flow for any of your HVA Service.”

“My husband recently passed away and Im trying to do things on my own. I could not figure out how to replace the filter on my heat pump, first I figured out I ordered the wrong filter, Sammy came over and showed me how to do it in 2 minutes. My replacement came today and I replaced it myself. Thank you Design Flow and Sammy”

“I'm impressed. Our Geo unit died in the middle of the night. We spoke with a live person who answered the call on the first ring at 3am. At 7:30am Brian (the owner) called us and spent two hours on the phone troubleshooting with me. Due to a major snowstorm and shipping delays it took a few days for the new blower to arrive, but thanks to Brian the house was warm enough. Cody came out and installed the new blower a few days later. Cody was very helpful, showed me a few things to look out for, and left me feeling confident that we were in good hands. I don't write reviews very often. These guys deserve the kudos.”
