Our tankless heater kept shutting off mid shower. They cleaned the lines, flushed the units and replaced a temperature sensor that had failed. He explained everything in plain language, and didn’t rush the job the membership plan got a same-day service and a serious break on the cost.

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

Our heating stopped working unexpectedly, and we needed an emergency HVAC repair. Superior HVAC arrived promptly, diagnosed the issue, and repaired the system the same day. The technician was friendly, knowledgeable, and got the job done right. Highly would recommend!!

The water pressure throughout our entire home had dropped to almost nothing over the weekend. The plumber systematically checked the system, found our main water pressure reducing valve had failed internally, and replaced it to restore perfect flow.
