“Marck did a great job. He repaired the plugged drain in our air handler so our unit no longer is dumping water into our basement when the air conditioner is running. Thank you! He was efficient and professional, gave us good advice and clearly described the problem and what he did to fix it. And the office crew squeezed us in with short notice and an already full schedule to get our problem fixed. Great job all the way around.”

“Design Air Inc. in Missoula, MT is an honest and professional company.
When our residential 27-year-old gas furnace stopped working during a below freezing 2019 winter night, Mike and his team helped us by installing a new gas furnace in two and a half days. The first day they troubleshot, loaned us space heaters to get us by, then advised us on the options, arranged for the new appropriately sized furnace to be delivered asap from Spokane, WA. Near noon on the third day the new gas furnace was operating and heating our home. We would highly recommend Design Air Inc, Missoula because the furnace installation was well planned, organized with excellent workmanship, and follow-up service. The cost of replacement parts and labor is rising everywhere. You pay for, for what your get. Design Air Inc, Missoula has been accredited by the Better Business Bureau since 9/1/ 2005, so they must be doing something right!”

“The guys at Design Air did an excellent job replacing our ancient furnace and upgrading our home with a central air system. The owner Mike, was nice and informative when he came both to do our estimate and after when he came to give us our final paperwork. The guys that came to install our system were very friendly, befriended our dog, were also very knowledgeable with any questions I had, and they made sure to put stuff in place to keep the floor and surrounding area’s clean, as well as cleaned up any mess they may have made. The lead tech also made sure that I was asked on any decisions before things were placed (new thermostat, new lines that needed ran etc.) I would highly recommend Design Air and the crew for any heating or air conditioning needs!!!”

“I actually was talked out of their service by the honesty of the technician. I ended up replacing a section of ducting myself. I will definitely recommend this firm to anyone in the future. Thanks for the sound advice. If I ever really do need heating tech service I will call these people first.”
