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.

My boiler started making strange noises, so I contacted Superior HVAC Service. Farid arrived on time, diagnosed the issue right away, and had it repaired quickly. He even checked my furnace to ensure everything else was working properly. Excellent service from a knowledgeable technician!
