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.

It's over 15 years old and has been through worse times, but the tech team they send in for maintenance just resurrected it.

Before the boiler replacement, they left my house cleaner than they expected it to be and the price was competitive as always.
