Moving to my apartment has become a real challenge for my family, and the broken boiler has become a ""cherry on top"". Fortunately, their tech arrived on-site the same-day, as well as quickly identified what had happened to the unit. The issue was solved in a blink of an eye. Nice!

I received three quotes from different companies to replace my 16-year-old air conditioner/heater. I chose Superior HVAC Service because of their price and the fact that they demonstrated the most knowledge. Instead of pushing for the most expensive air conditioner, they identified existing installation issues that others had overlooked. The installation team completed the work on time, even solving problems with outdated exhaust ducts connected to my water heater.
