About us
Commercial HVAC Since 2008, Built for Toronto Roofs
A Toronto shop and rooftop crew for RTUs, chillers, cooling towers and mechanical rooms. Red Seal, TSSA, ESA and CRE tickets on one team, and every job priced in writing.
Founder + Shop Director
Marco Romano
Marco founded Rooftop Units Toronto Pros in 2008 after years of GTA commercial HVAC work. He has held his Red Seal HVAC-R certification since 2004, along with TSSA G1 gas, ESA electrical and CRE chiller and cooling tower tickets.
The company was built around a simple rule from his own years on the tools: diagnose before you quote, quote in writing, and never send someone up a commercial roof who does not work on commercial equipment every day. That is why every repair starts with a tally, every install starts with Manual J/S sizing and a curb check, and every qualifying retrofit starts with a rebate filing.
Behind Marco is a crew of Red Seal HVAC-R leads, CRE chiller techs, sheet-metal fabricators, controls specialists and WSIB install crews, working from site assessment through commissioning.
