How to Choose the Right Furnace Upgrade for Your Home
Are you considering a furnace upgrade, but not quite sure where to begin?
We understand. Furnaces are more efficient than ever, with a plethora of features designed to keep you comfortable. They come in different sizes and shapes, some more powerful than others. They also have different price points based on their efficiency ratings.
The thermostat acts as a primary controller of your heating, ventilation, and air conditioning (HVAC) system, but it’s the furnace that does the heavy lifting. Working together with your ductwork, the furnace delivers warm air to every corner of your Montana home.
And always remember, a happy home is a warm one! It would only take a few cold days in a row with no indoor heat for all the pipes in your home to freeze.
What matters most is to pick the right furnace that fits your budget and the size of your home. Our team at Design Air has the knowledge and expertise to help you make that choice. We’re a trusted name in Missoula, MT, and the surrounding areas, for creating healthy homes. Give us a call today—we can schedule a free consultation to help with your next home improvement project.

A high-quality HVAC system deserves expert installation.
Even the best furnace can underperform if it’s not installed correctly. Don’t let poor workmanship keep you from enjoying the comfort and efficiency you paid for.
At Design Air, we specialize in precision furnace installation done right the first time. Our team carefully measures, calibrates, and inspects every detail to ensure peak performance.
Ask us about our flexible financing options (with approved credit) that make it easier than ever to bring lasting comfort to your home—without the upfront burden.
Furnace Repairs
Odd-sounding noises, a spike in energy bills, or constant cycling—these signs indicate the need for furnace repairs. Don’t wait for a minor issue to turn into a costly problem. Give us a call today if you detect a problem with your HVAC system. We service all major HVAC brands, so no matter what system you have, our technicians are equipped to diagnose and fix it. We promise never to replace a part unless necessary—or if we can demonstrate significant cost savings.
Furnace Maintenance
Want to get the most value from your HVAC system? Start with preventative furnace maintenance.
Your furnace works hard to keep your home comfortable—especially during those long winter months. But like any hardworking system, it needs regular care to perform its best. A preventative maintenance plan helps extend the life of your equipment, improves energy efficiency, and keeps small issues from turning into costly repairs.
At Design Air, we make maintenance easy and worthwhile. Our Design Air Protection Program is tailored to fit your home's specific needs, giving you access to priority service, professional technicians, and expert care throughout the year. No matter what system you rely on, our team is equipped to keep it running smoothly. With routine checkups and tune-ups, you’ll not only save on operating costs—you’ll enjoy greater comfort, reliability, and peace of mind.
