Central A/C stopped working Thursday night. Contacted Superior Friday morning and sent a technician within a few hours. They confirmed the worst but were able to install a brand new one the next day. The technicians were professional and courtious. Excellent service! I would recommend them any day!

Ryan from Superior HVAC Service replaced our 20-year-old furnace. The install was tidy and done in one day. He explained how to register the warranty and walked us through the new system. Would definitely use Superior HVAC again!

Our furnace wouldn’t stay lit. Ryan from Superior HVAC Service replaced the gas valve, adjusted pressure, and confirmed it was running safely. The workmanship was excellent.
