Our furnace broke down this year and we found Superior HVAC through researching for a licensed company local to us in the Niagara region. They were very quick to respond and get one of their technicians to work with us on installing a new furnace. Kurtis and his colleague worked very efficiently to remove the old furnace and install the new one making sure it's running and working perfectly before they left. Kurtis was very communicative with me and showed me the new system and how it works. We're very happy with the experience of working with Superior and their team. Pricing was very fair considering the quality of service provided. We will most definitely keep them in mind for future service calls

Fast, professional, and precise installation for my air handler. They've explained everything clearly and cleaned up afterward. Thank you Ian, their tech guy. Couldn’t be happier with the results. Would absolutely hire them again! Keep up the good work Superior HVAC!
