When you choose Design Air, you can feel confident your home will be treated as if it were our own. Whether you need furnace maintenance, repair, or installation of a new or replacement system, we’ll make sure your home is safe and comfortable for you and your family. We service and repair all makes and models of furnaces, gas forced air heat pumps, and fireplaces in Missoula. If you need heating service, Design Air is the company to call. Our skilled technicians are qualified to solve just about any repair or installation that you throw at us.
Routine maintenance is the best way to prevent untimely breakdowns and keep your furnace running efficiently. A good HVAC professional goes beyond vacuuming out dust. Our maintenance programs include not only cleaning, but also a full safety inspection, tightening wire connections and make any necessary minor adjustments to make sure your unit is in tip-top shape. Having maintenance done allows for necessary repairs to be scheduled on your timeframe, not as an emergency.
Don’t get left in the cold! Is your furnace acting up, blowing cold air, or making too much noise? Our experienced team of professionals is here to keep your home warm and cozy. We repair all makes and models, and we will never try to sell you a service that you don’t need. Our technicians are honest and hard working, and we’re always transparent and fair about the work we do. 24/7 Emergency service is also available should an issue arise with your system.
Sometimes a repair is not sufficient to fix your furnace. Sometimes a new furnace is the most cost-effective and energy-efficient way to go. We will always be honest with you about a possible furnace replacement. We value our time and your money––we don’t want to perform repairs or service on an appliance that is in need of replacement.

Heat Pump Service, Repair, and Replacement
We don’t just service furnaces. Many of our Missoula customers and its surrounding communities have air source heat pumps. Heat pumps are an energy-efficient and environmentally friendly way to heat your home. If you want a heat pump installed or serviced, or need repairs for your current one, Design Air is here for you.
Design Air also installs and maintains gas fireplaces. Gas fireplaces are an energy-efficient, cozy addition to your Missoula home. If you are looking to install a new one, or maintain your existing one, we are the company for you.
Are you having trouble with your fireplace? Maybe it won’t light or stay lit.
Gas fireplace repairs and maintenance are potentially dangerous if you are unqualified to handle them. A gas fireplace has a gas line, pilot light, thermocouple, and thermopile. When dealing with gas lines, it’s best to have a trained professional do the work to avoid any unnecessary danger. We recommend calling us for any problems you might be having.

“Tristan and Griffin did a wonderful job installing our new heater once our old as dirt one began failing. They worked fast, finishing up in less than half a day. They were super respectful, professional, and practiced safe social distancing during the COVID-19 pandemic. They went above and beyond when they vacuumed after they were done working and sanitized any surfaces they touched. Five stars!”

“After having a seasonal evaluation of my heating and AC units by Mark, it was necessary to replace both units due to the age of the units. After consulting with Doug on 4 options, we decided on units that were high efficiency and affordable. Tristen and Ed performed the install. They are two of the most professional and hard-working workers I’ve had the pleasure to hire. They were extremely knowledgeable and explained everything thoroughly. They were prompt both days and cleaned up after each work day. The entire team at Design Air, Inc.-Brandy, Mark, Doug, Tristen and Ed are exceptional. I would highly recommend these folks and will continue to call upon them for any future issues!!! Thanks for all your hard work!!!”

“Very friendly and nice.
Outstanding customer service and quality of work.
Our old furnace had died completely so we had them come out for a bid.
I was very impressed with their thoroughness in making sure I understood the different options for the new furnace and the work that would be involved for each type.
We got multiple bids, and theirs was very competitive so we went ahead and had them order us a furnace.
They came out for the install, right on time, and did great work.
The house and the work area were completely clean when they finished.
From there, they testing everything, took care of scheduling the inspection, and covered all the final paperwork with me.
Overall, we are ecstatic about our experience with Design Air and with our new furnace. I highly recommend them!”
