We had an issue with our heat not traveling thoroughly through our home, Superior HVAC service had a technician named Bennet at our house in give or take 40 mins, Bennet was really respectful and even showed us their process to cleaning the ducts before starting and before he was even gone he made sure our basement and master bedroom finally had proper air flow just in time for the cold weather. thank you again Bennet and everyone at Superior HVAC for making this happen

Today I had a problem with my heater not turning on, I called superior and within an hour they had a technician on their way to diagnose it. Dean arrived and within 5 minutes figured out that the thermostat was giving an incorrect reading. He temporarily fixed the issue and was on his way to get the parts required for the job and within just a couple hours of calling superior my problem was solved. I highly suggest you give these guys a try as they are quick, supportive and get the job done at a reasonable cost.
