I contacted Superior HVAC Sarnia for a furnace issue during cold weather, and their service was excellent. The technician arrived on time, identified a faulty component, and completed the repair efficiently. Everything was tested properly before they left

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
