“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!!”

“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.”

“I had called to report my system malfunctioning, and the temperature in my house was going down. A technician got back in touch with me within minutes and had me turn my breakers off and back on to see if it would get corrected. Unfortunately, it did not so I scheduled an appointment. It was right after a snowstorm and all the roads weren’t clear, but he (Cody) made it to the house and checked out my system. He was very friendly and knowledgeable. I appreciated the fast service and the efficiency of the staff. I would highly recommend your. company.”

“We had no heat on a day that was 2 degrees with wind chill!

Called Design Flow at 7 am, spoke with a live person, recieved a call back for technician availability within 10 minutes.

They told me arrival between noon and 2 pm, SAME DAY. Technician (Sammy) arrived at about 1:30 and had our heat up and running by 2:00 pm.

Sammy was friendly and very knowledgable!

When the need arises, I will call again!”

“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!”
