New Construction HVAC in Bryan / College Station, TX

Integrity 1st AC & Heating partners with builders, general contractors, and homeowners across the Brazos Valley to design and install HVAC systems that actually perform — the first time. From single-family homes and remodels to custom builds, additions, and light commercial projects, we handle the whole mechanical scope: load calcs, equipment selection, ductwork, controls, ventilation, and final commissioning.

What we do on new-construction projects

• Load calculations (Manual J) & equipment sizing (Manual S) — properly sized systems run quieter, last longer, and actually dehumidify in Texas humidity.
• Ductwork design & installation (Manual D) — sealed, insulated, balanced ductwork with returns sized for the home, not the truck.
• Equipment installation — furnaces, heat pumps, straight-cool AC, mini-splits, packaged units — every major brand, properly installed and registered.
• Ventilation & indoor air quality — fresh-air systems, ERV/HRV, bath fans, range venting, dryer venting, and whole-home filtration.
• Thermostats, zoning & controls — smart thermostats, multi-zone dampers, and simple Wi-Fi integrations homeowners can actually use.
• Startup, balancing & commissioning — we don't just set the thermostat and leave; we verify airflow, refrigerant charge, and static pressure on every system.

Why builders work with us

• On-time rough-in and trim — we show up when we said we would
• Clean job sites and clear communication with your super
• Competitive bids with itemized scopes, not mystery lump sums
• Warranty registration and documentation handed to your buyer at closing
• Long-term service relationship so your homeowners aren't calling you six months after closing

Custom homes & additions

Adding a primary suite, second story, or conditioned shop? We'll evaluate your existing equipment, run the numbers, and recommend whether to extend the current system, add a dedicated mini-split, or upgrade to a higher-capacity unit. No upsells you don't need.

Starting a new build or planning a remodel? Reach out early. The best time to design the HVAC is before the drywall goes up — and a 15-minute phone call now usually saves thousands later.
