Most HVAC companies are comfortable fixing a thermostat or replacing a small motor. But when it comes to “Special Projects”—the high-stakes, high-tonnage world of chiller change-outs and cooling tower removals—you need a different level of expertise. This is where GH Mechanical of Texas truly shines.
The Complexity of Scale Replacing a 100-ton chiller on a 20th-story roof isn’t just an HVAC job; it’s a massive logistical and engineering feat. It involves structural load calculations, city permitting, street closures, and complex rigging.
The GHMT Special Projects Protocol Our approach to these “Special Projects” is centered on one goal: Zero Business Interruption. We know that if a hospital or a data center loses cooling for even a few hours, the consequences are disastrous.
-
Pre-Construction Planning: Our engineers conduct a thorough site audit. We look at crane placement, outrigger pressure on the pavement, and wind-speed safety windows.
-
Precision Rigging: We use certified riggers and the latest lifting technology to ensure that massive units are moved with millimeter precision. Whether it’s a “Mini MOCCS” cantilever system for tight spaces or a 500-ton hydraulic crane, we have the tools for the job.
-
Piping & Integration: Once the new unit is in place, the real work begins. Our master pipefitters and automation experts work through the night to weld new connections and integrate the unit into the existing BAS.
A History of Success GHMT handles projects ranging from $50,000 to $23 million. We have successfully managed complex change-outs for some of the largest commercial and industrial facilities in the Gulf Coast region. Our reputation is built on the fact that we handle the “impossible” jobs that other contractors shy away from.
Why It Matters to You When you choose GHMT for your special project, you aren’t just hiring a mechanic. You are hiring a project management team that understands the intersection of engineering, logistics, and facility operations. We get the job done right, on time, and without the headaches.
