RTUs are load-bearing infrastructure for your business. We specialize in commercial systems — understanding how your rooftop unit integrates with static pressure, ductwork design, and building envelope to function as a precision climate system, not just a box on the roof.
We measure amp draw, Total External Static Pressure (TESP), and refrigerant charge before we quote anything. If your RTU is failing, we find out why — because replacing a unit without fixing the root cause means your next unit fails the same way, on the same timeline, at the same cost.
We don't pull the old unit's tonnage off the nameplate and order the same size. We run a Manual J load calculation for your facility. An oversized RTU short-cycles, never controls humidity, and burns out prematurely. A right-sized system runs longer cycles, pulls latent load, and pays the difference back in energy savings and equipment life.
Salt air and sulfur from the petrochemical corridor eat standard coils up to 40% faster than inland environments. We engineer for that reality — specifying corrosion-resistant coatings, materials, and configurations that hold up against the specific chemical environment your equipment actually lives in. Longevity isn't a feature we sell; it's a spec we build to.
We translate every technical finding into plain language — what's wrong, why it matters, what it costs to fix, and what it costs to ignore. You get the data. You make the call. No artificial urgency, no fear-selling, no recommendation that doesn't have a measurement behind it.
A failed RTU isn't a comfort inconvenience; it's lost productivity, unhappy tenants, and spoiled product. Our commercial team moves with the urgency that downtime demands — diagnostics, parts sourcing, and installation coordinated to get your facility back to operational temperature as fast as the engineering allows.
