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.
