I scheduled water boiler maintenance with Superior HVAC, and it was excellent. The technician named Farid was thorough, professional, and explained everything clearly. I’m confident my heater will last longer now.

Superior HVAC service was awesome start to finish. My furnace died on the coldest night of the year and they came out late night to diagnose my unit. My new furnace was installed the next day! Highly recommend them

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.
