I contacted Superior HVAC for an emergency on Family Day.They were excellent and easy to deal with.The technician who showed up was Matthew and he was great!Very honest, clear communication, clean and concise with what I needed to do and what the next steps would be. I would defiantly use them again, and would be comfortable referring Matthew.

Superior HVAC was able to replace my 15 year old furnace. The whole process was very quick and professional!
