Overall, I had a good experience. The repair turned out to be much more complicated than anyone expected, and in the end my air conditioner needed to be replaced rather than repaired. While it was frustrating to be without A/C during an extreme heat wave, the team was responsive, kept me informed, and worked to get everything resolved. The new unit is working great, and I'm very happy with the final result. I appreciate their professionalism and would recommend them.

Superior HVAC came to my houseonly hours after I called. They diagnosed my furnace and were able to replace it the same day! Highly recommend

The AC was running constantly but the house wasn't cooling. the technician found restricted airflow from a collapsed duct section combined with a low refrigerant charge. He fixed both issues in one visit and explained everything clearly.

I called this company because our home wasn't cooling evenly and some rooms were much warmer than others. The technician inspected the system thoroughly and identified an airflow issue right away. He fixed the problem quickly and now the entire house feels comfortable again. Great customer service and honest pricing
