HVAC Estimating for Texas Contractors

Texas's extreme summer heat — with design cooling loads among the highest in the country — drives oversized HVAC systems, high-efficiency equipment mandates under the Texas Energy Code, and significant ductwork in unconditioned attic spaces that must be insulated to R-8 minimum. Texas requires an HVAC contractor license through the Texas Department of Licensing and Regulation (TDLR). Technicians must hold an EPA 608 certification. No state prevailing wage on private work.

What Your HVAC Estimate Includes

Ductwork quantities (LF and SF) by shape, size, and gauge
Equipment schedules (AHUs, RTUs, FCUs, chillers, boilers)
Piping quantities by system (chilled water, hot water, refrigerant)
Insulation quantities by duct and pipe system
Controls and DDC system scope
TAB (Test, Adjust, Balance) allowances
Labor hours by trade classification
Excel workbook with annotated PDF markups

Texas-Specific Scope Considerations

  • › Texas Energy Code (based on IECC) requires high-SEER equipment and duct leakage testing
  • › Attic ductwork must be insulated to R-8 minimum — a significant material cost driver
  • › Dehumidification systems increasingly specified in Houston and Gulf Coast markets
  • › Rooftop unit (RTU) replacement scope is large due to flat-roof commercial stock across the state
