HVAC chiller line welding

In Arizona, HVAC chiller systems aren’t a luxury—they’re a necessity. When it comes to chiller line welding, the work has to be right the first time to handle the flow, pressure, and relentless summer heat. Earthquake Welding is equipped to provide certified welding for HVAC chiller lines across Phoenix, the Valley, and statewide.

We weld carbon steel and stainless piping for chiller supply and return lines, headers, risers, and mechanical room connections. Whether it’s a high-rise in Tempe, a data center in Mesa, or a commercial build in downtown Phoenix, we weld to ASME B31.3 standards and facility requirements.

When the cooling system is mission-critical, the welds behind it have to hold—no exceptions
