What we deliver for McKinney projects

McKinney areas we work

Stonebridge Ranch, Adriatica Village, Tucker Hill, Craig Ranch, Trinity Falls, downtown McKinney, Eldorado Heights, Wilmeth Ridge, Wynbrooke, Mallard Lakes, and everywhere in between. New construction subdivisions, custom builds, remodels, and permit catch-up jobs all welcome.

Common McKinney scenarios we solve

Permit got kicked back asking for Manual J: A homeowner replaces an HVAC system without a permit, the city catches it on a future inspection, and now they need stamped calcs for the equipment that's already installed. We handle this every week. Same-day turnaround available.

New construction needs J/D/S package: Builder needs the full package before the mechanical inspection. We size off plans you upload through the intake form.

Tenant finish-out for downtown McKinney: Restaurants, medical offices, retail buildouts in the historic district or commercial corridors. Manual N + Q sized per TI scope.

Refrigeration for restaurants: Walk-in cooler and freezer design for new restaurant builds in Adriatica or Craig Ranch retail.
