Commercial AC installation done right — from sizing to commissioning

A commercial air conditioning installation is a long-term investment. The equipment you put in today will be running your facility for 15–20 years, consuming energy every single day, and either performing efficiently or wasting money and failing prematurely based largely on how well it was sized and installed.

Rock Hard Refrigeration manages commercial AC installations from initial load calculation through final commissioning — selecting the right system for your building's actual cooling demands, coordinating crane equipment for RTU placements, handling all electrical and refrigerant connections, and verifying full system performance before we hand the keys back to you.

Proper sizing is the foundation of every installation

Oversized commercial AC units short-cycle — they cool quickly but can't remove humidity, leading to uncomfortable spaces and excessive wear. Undersized units run constantly without ever catching up on the hottest Texas days. We perform detailed load calculations to select equipment that matches your building's actual requirements.

What's included in our commercial AC installation

Every Rock Hard commercial AC installation covers the full scope — we don't hand off partial jobs to other contractors or leave you managing multiple vendors.

Load calculations and system sizing — accurate cooling load analysis based on your building's square footage, occupancy, insulation, solar exposure, and operational requirements
Equipment selection and procurement — we recommend the right system type, brand, and model for your facility and budget from major commercial HVAC brands
Crane coordination for RTU installations — we coordinate and manage crane equipment, rigging, and the complete lift process for rooftop package unit placements
Equipment placement and curb mounting — proper placement, curb adapter installation, and equipment mounting to manufacturer specifications
Refrigerant lines and charging — refrigerant line installation, proper leak testing, and factory-specification refrigerant charging
Electrical hookup and controls — power connections, disconnect installation, thermostat wiring, and zone control setup
Code compliance and documentation — all work performed to Texas commercial HVAC code, fully insured, documentation provided for permits and warranty
System commissioning and performance verification — full system startup, airflow verification, temperature differential testing, and operational walkthrough before handover

Commercial AC installation for North Texas build-outs & renovations

Whether you're outfitting a brand-new commercial tenant space, replacing aging equipment in an established facility, or adding cooling to a building expansion, Rock Hard coordinates your commercial AC installation to fit your project timeline and existing infrastructure.

We work alongside general contractors, electricians, and other trades on commercial build-outs — providing the HVAC scope as part of a coordinated project rather than as a standalone vendor who shows up after everyone else is done. Our familiarity with commercial refrigeration systems also means we can flag and resolve conflicts between HVAC ductwork and refrigerant lines before they become change orders.

Why installation quality matters

The installation sets the system's ceiling

A commercial AC system can only perform as well as its installation allows. An undersized unit runs constantly and never catches up. An oversized one short-cycles, fails to remove humidity, and wears out fast. Improper refrigerant charge degrades efficiency from day one. Poorly routed ductwork creates hot spots that no thermostat setting can fix.

Accurate load calculations — not rule-of-thumb sizing
We calculate your building's actual cooling load before recommending any equipment. Square footage is only one variable — we factor in occupancy, solar exposure, insulation, internal heat loads, and North Texas climate data.
Factory-spec refrigerant charge every time
We charge commercial AC systems to manufacturer specifications using calibrated equipment — not by feel. Proper charge is the single biggest factor in first-year system efficiency and long-term compressor life.
Performance verified before we leave
We don't consider an installation complete until we've tested airflow, measured temperature differential across the coil, verified refrigerant pressures, and confirmed controls are working correctly throughout all zones.
