New Construction HVAC in Houston, TX
Design-build HVAC for custom homes, additions, and light commercial builds.
New construction is the one chance to get HVAC exactly right: ducts sized and routed before drywall, equipment matched to a real load calculation, and returns placed where they actually work. Fixing these decisions after move-in costs five times more.
We work directly from your plans with builders and homeowners across the Greater Houston area — from single custom homes in Katy and Cypress to light commercial build-outs — delivering Manual J (load), Manual D (duct design), and Manual S (equipment selection) documentation with every project.
What’s included in every new construction hvac
- Plan review and full Manual J / Manual D / Manual S design package
- Duct layout optimized for Houston attic conditions (buried-duct options for efficiency)
- Equipment selection across all major brands to hit budget and efficiency targets
- Rough-in, set, and trim-out scheduling coordinated with your builder
- Zoning design for two-story and large single-story plans
- Permits, inspections, and final commissioning with airflow verification
- Homeowner orientation at trim-out: thermostat, filters, and warranty
When Houston homeowners call us for new construction hvac
Building a custom home
Bring us in at plan stage — moving a return or upsizing a trunk line on paper is free; after drywall it is demolition.
Large addition (400+ sq ft)
Additions big enough to need their own load calculation often justify a dedicated second system rather than stretching the existing one.
Barndominium or metal building
Metal buildings need specialized load and condensation planning — a standard residential design fails here.
Light commercial build-out
Offices, retail, and medical suites up to light-commercial tonnage with packaged or split systems.

New Construction HVAC questions
When should I involve an HVAC contractor in a new build?
At plan stage, before framing. Duct chases, return locations, and equipment closets are framing decisions — changing them later is expensive.
Can you work with my builder’s schedule?
Yes. We coordinate rough-in after framing, set equipment before insulation closes access, and trim out with your builder’s final schedule.
Is it worth paying for better ducts in new construction?
In Houston attics that reach 140°F, duct quality is the single biggest efficiency factor you fully control at build time. Buried and sealed ducts routinely cut cooling costs 15–25%.
Do you provide the load calculation documentation?
Every new construction project ships with written Manual J, D, and S documentation — useful for permits, energy programs, and your own records.
