People who know what they’re doing are the ones who get it done right.

They show up when they say they will; fix (or replace) what’s broken the first time; and take the time to get you exactly what you need, when you need it, without wasting time to try and sell you on what you don’t. 

That’s what you’ll get from Mister B’s.

We’re proud to continue showing up for you—20 years and counting.

Thank you, Cheyenne and Southeast Wyoming, for trusting us to pick up the phone—and show up at your home or business—when you need us. 

It’s because of you that what began as a one-truck operation in 2003 is now Cheyenne’s most trusted, reliable and fair heating and cooling (HVAC) service provider, celebrating its 20th year in business in 2023. 

We’re locally owned, family operated, and proud to provide the honesty, reliability, and quality of work you deserve—now, and for decades to come.
