Keep your home warm through Montana's toughest winters.
Furnace repair, installation, and maintenance for the Flathead Valley and Gallatin Valley. NATE-certified team. Flat-rate pricing.
When your furnace stops working in January, you don't need a sales pitch. You need someone who answers the phone, shows up the same day, and tells you what's actually wrong.
Western Sky handles furnace repair, heating system installation, and seasonal maintenance across the Flathead Valley and Gallatin Valley. Whether your gas furnace needs a quick fix or your home is ready for a complete system upgrade, our NATE-certified team will walk you through your options with flat-rate pricing. No surprises.
We also install and service heat pumps and dual-fuel systems for homeowners looking for year-round efficiency. Cold-climate heat pump technology works in Montana winters, and our team can help you decide if it's the right fit for your home.
What We Fix and Install
Our heating services cover the full range of what your home might need: gas furnace repair and replacement, heat pump installation and service, dual-fuel system setup, thermostat upgrades and smart controls, and heating system safety inspections.
Every job starts with an honest diagnosis. If your furnace has more life in it, we'll tell you. If it's time for a replacement, we'll explain why and give you options that fit your budget.

We show up on time, we give you flat-rate pricing before we start, and we tell you the truth about your system. If the repair is straightforward, we handle it the same day. If your system needs more work, you'll know exactly what it costs and why before we touch a tool.

What we offer
Frequently asked questions
How do I know if my furnace needs repair or replacement?
If your furnace is cycling frequently, making unusual noises, or your heating bills have spiked without a change in usage, it likely needs service. Our team will diagnose the issue and give you honest options. If a repair will keep your system running reliably, we'll say so. If replacement makes more sense, we'll explain why.
How long does a furnace installation take?
Most residential furnace installations are completed in one day. If your home needs new ductwork or significant modifications, it may take longer. We'll give you a clear timeline before we start.
Do you service all furnace brands?
Yes. We provide factory-authorized service for all major brands, including Ruud. No matter what system is in your home, our NATE-certified team can repair, maintain, or replace it.
When should I schedule a heating tune-up?
Fall is the best time, ideally before the first cold snap. A tune-up catches small problems before they become expensive emergencies during Montana's coldest months.
