Superior HVAC saved our lives. Our furnace gave out and left us freezing for 3 days before we called. Problem was solved with their new Lennox furnace. Wouldn’t hesitate to call again!

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
