The guys did a terrific job repairing my boiler's thermostat. They were at my doorstep the same day I called and had the system up and running very quickly!

On a cold winter day, my furnace died of old age. I happened to stumble upon Superior HVAC Service and the next morning, a technician was at my place! The level of professionalism from the first call to the final cleanup was impeccable. I’m very pleased with the furnace installation experience I’ve had!

This product met my hopes. They sent me a technician to service the furnace in two hours. When the ambulance broke down completely, we needed an ambulance. I would highly recommend them to anyone interested in learning more about them.

For the past two years, the semi-annual maintenance of our HVAC system by Superior HVAC Service has been consistently smooth. The technicians have been punctual, conducting their tasks with thoroughness and maintaining a professional attitude throughout. They have not only offered valuable suggestions and explanations but also provided clear recommendations for cost-saving measures. The trust I have in their commitment to quality service and customer satisfaction extends to the company as a whole. Without reservation, I confidently recommend Superior HVAC Service.

Tanner and Jermaine excelled in installing our new furnace. With our original furnace of over 30 years on its last legs, we opted for a new high-efficiency system with Superior HVAC Service. They were punctual and cleaned up thoroughly, and the system is now running smoothly and quietly. Before leaving, Tanner and Jermaine provided a comprehensive explanation of everything. I highly recommend them. Kaziel played a crucial role in helping us choose our new furnace after identifying issues with the igniter during the annual cleaning.
