The commercial water fountain in our main storefront lobby stopped draining and started pooling over. The plumber snaked the narrow interior lines, removed a heavy accumulation of mineral scale, and verified everything discharged perfectly.

Superior HVAC installed central air in my home, and I’m extremely happy with the results. The team was professional and efficient. The system cools perfectly. Great service.
