Commercial Rooftop Repair — 20-Ton York RTU (Coil Replacement, Not Full Swap)
When a Norwalk business was told they needed a full 20-ton rooftop replacement, wtech22 Heating and Cooling found a smarter fix. After diagnostics, we traced the root cause to a persistent leak in one of the coils. We partnered directly with York to source the correct part number and replaced the coil, then evacuated, charged, and verified operation to manufacturer specs.
The result? The system is running as designed, downtime was minimized, and the owner saved significantly versus a full unit changeout. We earned a new long-term customer because our approach focused on cost-effective repair, not unnecessary replacement.
Need a second opinion before you replace your RTU? We can help.
