We switched to a more efficient unit, and our energy use has dropped noticeably. The team handled the paperwork too.

The work was neat and on schedule. The replacement part cost more than I hoped, but the labor was reasonable.

They serviced both the heating and cooling systems and explained what each part does. I’d book the yearly checkup again.

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.

Our AC stopped cooling overnight, and they responded the same day. They replaced a faulty capacitor, and everything has been running perfectly since.

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.

Superior HVAC fixed an issue with our air conditioner that was blowing warm air. The technician replaced a failed capacitor and the system was cooling properly before he 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

I noticed some garden beds were always overwatered while others stayed completely dry, and this company diagnosed leaky irrigation lines right away. After repairing the PVC and rebalancing the sprinkler heads, the entire lawn gets even coverage.
