Lewis Heating and A/C

🎓❤️ Join us in celebrating Tommy Lewis, Havre High School Class of 2026! What a milestone… and what a bittersweet, proud moment for our family.

Over the next couple of days, we’ll be taking some time to soak in the memories, celebrate our graduate, and enjoy this special season of life.

Our office will be CLOSED Thursday & Friday, but our technicians will still be working and monitoring calls/texts at 406-945-3610. We’ll be available — just a little in and out, and response times may be a bit slower than usual.

Thank you for your patience, your understanding, and for supporting our small family business through all of life’s big moments. Your support means more to us than you know.

Last week: “My AC quit!” 🥵
This week: “Can you fix my furnace?” 🥶🔥
Meanwhile… we’re installing fireplaces.
Just another week in Montana. 😂

🔥 Big recognition for our team 🔥

As a co-owner of Lewis Heating & A/C, I get a front-row seat to the work that happens behind the scenes—and Shaylee brings it every single day. 💪

She was recognized at the Fire Within event through the Great Falls Development Alliance with the Inspire award, honoring women entrepreneurs who are making a real impact in their business and community. 🔥📈

No shortcuts. Just grit, leadership, and consistency. 💯

Proud doesn’t even begin to cover it. 👏

👇 Drop a 🔥 to help us celebrate her!

Most homeowners don’t realize this… 👇

Your furnace and AC are only as good as the ductwork behind them.

Poor duct design =
❌ Hot and Cold Spots
❌ Weak airflow
❌ Higher energy bills

At Lewis Heating & A/C, we design and install duct systems that actually move air the way they should.

Because comfort isn’t luck… it’s design.
