Air Conditioning Repair, Installation & Replacement
Our technicians repair, install, and replace central air conditioning systems, diagnosing everything from a unit that won’t kick on to one that’s running nonstop without cooling the house.
A lot of Frenchtown’s newer homes sit on lots that were farmland or open pasture until recently, which means the shade trees a decades-old Missoula neighborhood takes for granted just haven’t had time to grow in yet. A house without established shade gets more direct sun on its walls and roofline through a summer afternoon, and that’s a real factor in sizing a system correctly, not just a landscaping detail to sort out later.
Furnace Repair, Installation & Replacement
We repair, install, and replace gas furnaces for homes throughout Frenchtown, whether that’s a no-heat call in the middle of winter or a planned replacement ahead of one failing.
Frenchtown’s roots go back to French-Canadian and Métis families who settled the valley in the 1850s, and a fair number of the area’s older farmhouses have been added onto more than once since, sometimes across multiple generations of the same family. A furnace that was sized for the original structure doesn’t always keep up once a second or third addition is drawing off the same duct system, which is worth checking before assuming the existing unit is simply wearing out.
Heat Pump Repair, Installation & Service
Whether you’re maintaining an existing heat pump or considering one as an alternative to a gas furnace, our technicians handle repairs, installations, and seasonal service for both ducted and ductless systems.
The Frenchtown Valley sits in enough of a rain shadow off the Bitterroot Range that the area has historically run drier than a lot of the rest of western Montana, which is part of why it was developed as irrigated farmland going back over a century. That drier air doesn’t change the basics of what a heat pump needs here in the winter, but it’s still worth confirming the backup heat is sized and set up correctly for this specific property rather than assumed from a spec sheet.
Ductless Mini-Split Systems
For a converted garage, a finished bonus room, or any space that’s never been comfortable no matter what the rest of the house is doing, we install and service ductless systems that condition a room directly.
We’re seeing more Frenchtown homeowners turn an attached garage into a home office or a spare bedroom, and those spaces almost never come with more than a single supply duct, if that, since the garage was never part of the original heating and cooling plan. A ductless unit is usually the more direct way to actually make a converted space like that comfortable, without trying to extend a duct system that was never sized to reach it.
Indoor Air Quality Solutions
We install and service indoor air quality equipment, including filtration, purification, and humidity control, designed to work alongside a home’s existing HVAC system rather than replace it.
Frenchtown is still surrounded by working farmland, and tilling and harvest on the fields around town can kick up more airborne dust for a stretch than a standard filter is built to keep up with. Homeowners near the fields sometimes notice more dust settling indoors during planting and harvest weeks specifically, which is a good time to have filtration checked rather than waiting until it becomes a year-round complaint.
Why Frenchtown Homeowners Choose Design Air
From our Bulwer Street shop, Design Air has covered Frenchtown since Mike Breidenbach founded the company in 1994, making the trip up I-90 often enough that it’s part of our regular route rather than a special case. That tenure comes with real recognition from our manufacturer partner: Bryant has named us a Circle of Champions and Medal of Excellence dealer, and separately certified us as a Bryant Certified Ductless Pro, a distinction most Bryant dealers don’t hold. We’ve served this valley for over three decades, in a town that’s been around since the 1850s, and we plan on being part of it for a while longer.
Frenchtown HVAC Repair & Maintenance Questions, Answered
Our Frenchtown farmhouse has been added onto a couple of times over the years. Does that change how a new furnace should be sized?
Yes, it’s worth having sized for the house as it exists now rather than matched to whatever’s currently installed. Additions built at different times often mean the duct runs and insulation levels vary room to room, and a furnace that was right for the original structure can fall short once it’s also covering a mudroom or bedroom addition tacked on later. We run a load calculation on the whole house as it stands today, not just the original footprint.
We built on a new lot in Frenchtown that doesn’t have any mature trees yet. Does that actually matter for AC sizing?
It does. A house with no established shade takes on more direct sun through the afternoon than a similar house on a tree-lined lot, and that added heat load is a legitimate factor in choosing the right size system, not just a comfort issue that landscaping will eventually fix. We factor lot conditions like that into the sizing rather than defaulting to a standard recommendation.
Does Frenchtown’s drier climate change anything about how a heat pump performs here compared to closer to town?
Not in a way that changes the fundamentals, but it’s still worth having the system checked for this specific property rather than assumed. What matters more than the valley’s general climate is whether the backup heat is sized and configured correctly for your home’s actual heat loss, which we verify on every heat pump install regardless of exactly where in the valley it’s going.
I turned my attached garage into a home office, and it’s never comfortable. What’s the actual fix?
Garage conversions almost always inherit whatever ductwork the garage originally had, which in most cases is none or close to it, since the space wasn’t built to be heated and cooled like the rest of the house. A ductless mini-split conditions that room directly without requiring us to tie into and rebalance the main system’s ductwork, and it’s usually the more practical fix than trying to extend a duct run into a space that was never part of the plan.
The dust from the fields around Frenchtown gets bad during planting and harvest. Will a regular filter handle it?
Not for long. A standard 1-inch filter is rated for typical household dust, not the heavier load that blows in off surrounding fields during active tilling or harvest. If you notice more dust settling indoors or your filter looking dirty well before its replacement date during those weeks specifically, that’s a sign it’s worth talking about a higher-capacity filter or supplemental filtration rather than just changing filters more often.
Do I need a permit to replace my furnace or AC in Frenchtown?
Yes. Frenchtown is unincorporated, so permitting goes through Missoula County rather than a city building department, and the county requires a mechanical permit for work on heating, cooling, and ventilation systems, including furnace and AC replacements. We handle that permitting as part of the installation.
Are there rebates available for upgrading to a heat pump or high-efficiency furnace in Frenchtown?
NorthWestern Energy, which serves the Frenchtown area, runs seasonal E+ rebate programs for qualifying air-source and ductless heat pumps as well as high-efficiency natural gas furnaces, though the amounts and program windows shift from year to year. We can confirm what’s currently available and whether your project qualifies.
