Great company and great service. The AC replacement was done faster than expected, and the team was very respectful of my home. They explained the process clearly and made everything stress-free. My new system works perfectly and cools evenly throughout the house.

Called about a furnace failure after 5 on a Friday and they sent someone within 3 hours! While it was a simple fix, they explained everything, told me how to prevent it from happening again, and only charged me the diagnostic fee.

We called Superior HVAC because our air conditioner was running constantly without cooling the house properly. The technician found a refrigerant leak and repaired it the same day. He recharged the system and checked all the airflow levels afterward. The cooling works perfectly now
