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.

Our gas fireplace wouldn't light. Superior HVAC Service sent Maria, who quickly cleaned the pilot light and got it working again. She was friendly, efficient, and charged a very reasonable fee. Highly recommend!

I recently had my furnace repaired, and the experience was outstanding. Ian, the technician from superior HVAC services, arrived right on time, maintained a courteous demeanor throughout the visit, and clearly explained both the issue and the repair process. His expertise and attention to detail quickly restored my furnace to peak condition. I truly appreciate the prompt, professional service and wouldn’t hesitate to recommend this company for any heating needs.

Superior HVAC is the best! Ian replaced our old tankless water heater, and the installation was flawless. The water heats up instantly, and our energy bill is lower already!
