Air Conditioning Repair, Installation & Replacement

Our technicians repair, install, and replace central air conditioning systems, diagnosing everything from a unit that won’t start to one that’s running constantly without keeping the house cool.

Clinton’s stretch of the Rock Creek and Clark Fork corridor runs a lot more wooded than the open valley floor closer to Missoula, and a home tucked into the tree line doesn’t take on the same heat load as one sitting in full sun most of the day. That’s a break most summers, but it also means a system that’s rarely had to work hard can slip without anyone noticing until the one real hot stretch it actually needs to keep up.

Furnace Repair, Installation & Replacement

We repair, install, and replace gas furnaces for homes throughout Clinton, whether that’s a no-heat call in the dead of winter or a planned replacement ahead of one failing.

Clinton got its start in 1883 as a Northern Pacific Railroad stage stop, and today it sits at the highest elevation of any community in our service area, close to 3,458 feet along the upper end of the Clark Fork valley toward Deer Lodge. That elevation means colder average winter temperatures than homes closer to Missoula, and a furnace that keeps up fine down in the valley isn’t automatically sized right for conditions up here.

Heat Pump Repair, Installation & Service

Whether you’re maintaining an existing heat pump or considering one instead of a gas furnace, our technicians handle repairs, installations, and seasonal service for both ducted and ductless systems.

Clinton is the far edge of our regular service area, so we make a point of double-checking a heat pump’s backup heat setup on-site before we leave rather than treating it as something to circle back on later. It’s a detail that matters more the farther a property sits from a quick return visit.

Ductless Mini-Split Systems

For a bonus room, a converted space, or a property that isn’t occupied year-round, we install and service ductless systems that condition a space directly.

Rock Creek’s reputation as one of Montana’s best fly-fishing rivers has left Clinton with a fair number of guest cabins and seasonal properties that only see regular use part of the year. A ductless system lets an owner keep a cabin above freezing through the off-season and switch on real heating or cooling only when the property’s actually in use, rather than running a full central system for a place that sits empty most of the year.

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.

The hillsides around Clinton are more heavily forested than the open valley floor closer to Missoula, and conifer pollen from the surrounding pine and fir can coat a property here more heavily during a spring bloom than it would in a less wooded part of the valley. A standard filter usually keeps up, but it’s worth checking it sooner than the printed replacement date during a heavy pollen year.

Why Clinton Homeowners Choose Design Air

Design Air has covered Clinton from our Bulwer Street shop since Mike Breidenbach founded the company in 1994, even though it’s the farthest reach of our regular service area. That distance hasn’t changed the credentials we bring to the job: 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. Clinton homeowners get the same standards we hold ourselves to everywhere else in the valley.

Clinton HVAC Repair & Maintenance Questions, Answered

Our place near Rock Creek gets really hot in the afternoon but cools off fast once the sun goes down. Does that change how AC should be sized?

Yes, it’s worth factoring in. A system sized only for the hottest part of the afternoon can end up running longer than it needs to once the evening cools off quickly, which is a common pattern at Clinton’s elevation. We size for how the whole day actually plays out here rather than just the peak reading.

Why does my furnace in Clinton seem to run more than it did when we lived closer to Missoula?

Elevation is the biggest factor. Clinton sits at roughly 3,458 feet, noticeably higher than most of the rest of our service area, and that generally means colder average temperatures and more overnight cold than homes down in the valley see. A furnace that performed fine at a lower elevation isn’t automatically sized right up here, so it’s worth having it checked against the house rather than assuming it should perform the same.

We have a cabin near Rock Creek that we only use part of the year. What’s the best way to heat and cool it without running a full system?

A ductless mini-split is usually the most practical setup for a seasonal property like that. It lets you keep the cabin above freezing during the months it’s sitting empty and switch on full heating or cooling only when you’re actually there, without the cost of running a central system for a property that’s occupied only part-time.

We get a lot of pine pollen in the spring around our place outside Clinton. Does that mean we need a different kind of filter?

Not necessarily a different filter, but it’s worth checking it more often during a heavy bloom. The forested hillsides around Clinton put out more conifer pollen than a homeowner would see out on the open valley floor, and a filter rated for typical conditions can load up faster than its printed replacement schedule suggests during a bad pollen year.

Do I need a permit to replace my furnace or AC in Clinton?

Yes. Clinton 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 Clinton?

NorthWestern Energy, which serves the Clinton 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.
