Our Story

We’re Bryant and Aliona Bonano, the husband-and-wife team behind Imperium Heating & Cooling. We’re happy to share a vision that drives everything we do: delivering HVAC solutions that enhance property value and provide long-term comfort for the people who rely on them.

Bryant’s passion for mechanical systems began at sixteen during a summer job at a heating and cooling plant in Ohio. Guided by his father, that early experience sparked an interest that grew into a lifelong career built on skill, dedication, and integrity. Over the decades, he’s gained extensive experience and built strong relationships with clients and partners who value his reliability and craftsmanship.

Since 2012, Imperium has proudly served St. Louis and the surrounding areas, providing honest, high-quality HVAC service rooted in trust, precision, and pride in our community.

Trusted by Those Who Know

“We needed to replace our two condo HVAC units in our multi-story penthouse condo in downtown St. Louis, and received bids from a few contractors. It was going to be an expensive endeavor, so we wanted to ensure it was done right.

Bryant of Imperium HVAC was recommended to me by a friend who was a condo building property manager as someone who did excellent, quality work at an affordable price - he exceeded my expectations, and beat the other quotes on price.

Bryant is a very professional, skilled, responsive and affordable contractor who is super mindful of your time, schedule and your home, and overall a great guy who does excellent work. He explained all options available at the quote stage, completed the job quickly, and left the work areas spotless. After our experience with Bryant, we also had him quote out replacing our third floor, rooftop mini-split and for when we decide to replace it, and he will get all of our HVAC replacement/maintenance in the future.

I highly recommend Imperium for anyone needing HVAC work done - they will treat you right.'“
