About Us
-Bryant and Aliona Bonano, Owners of Imperium Heating & Cooling
Our Story
Founded in 2012 by husband-and-wife team Bryant and Aliona Bonano, Imperium Heating & Cooling was built on the belief that true comfort requires both technical expertise and a seamless customer experience. We are driven by one question: Are you comfortable?
Built on Experience and Care
Bryant brings hands-on HVAC expertise shaped by years in the field, while Aliona ensures everything beyond the field work supports a smooth and comfortable experience for clients. Together, they prioritize clarity, sound decisions, and dependable comfort at every stage.
Rooted in the Trade
Bryant learned the HVAC trade from his father at a young age and built his career on craftsmanship, accountability, and doing the job right the first time. Those values are why St. Louis homeowners, property managers, and commercial developers trust him on projects ranging from historic properties like the Lindell Apartments to modern residential upgrades across Clayton, Soulard, the Central West End, and beyond.
How We Serve
We serve St. Louis and the surrounding areas with proven expertise in furnaces, air conditioning systems, heat pumps, custom ductwork, and building-specific HVAC design. From new system installations and replacements to indoor air quality solutions and seasonal inspections, our work is centered on reliable comfort, clear communication, and long-term value for the people who depend on their systems every day.
Our Standard
At Imperium, comfort isn’t a tagline. It’s a question we ask at every step: Are you comfortable?
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.'“
