Kevin was the best! Our furnace stopped working in the middle of the night, and Superior HVAC had someone at our door first thing in the morning. Amazing service!

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.
