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.

These guys really know their stuff! Our furnace went down earlier in the week and our house was freezing! George was able to come and asses right away, and provided solutions that worked well for our family and budget. I highly recommend Superior Heating and Air Conditioning!

Kurtis replaced our broken water heater during an emergency, and we couldn’t be more satisfied. He showed up quickly and worked with precision.

We called Superior HVAC and they sent Kevin to fix our boiler, his attention to detail was exceptional, he was so polite and helpful. He explained the problem and the steps he took to resolve it, and we can tell he truly cared about providing the best solution. We felt the price was very fair for the outstanding quality of service
