Commercial HVAC Estimating Services in Texas
Precision mechanical takeoffs and labor estimating for Texas mechanical contractors, sheet metal fabricators, and commercial HVAC bidders.
Commercial HVAC Estimating in Texas
HVAC systems in Texas are subject to some of the most punishing cooling load demands in North America. With commercial facilities operating under extreme triple-digit summer design temperatures and volatile ERCOT grid power conditions, Texas mechanical contractors require accurate, plan-calibrated estimates. JLG Estimating provides comprehensive commercial HVAC estimating services tailored to the thermal dynamics, energy codes, and fast-track bidding cycles of Texas projects.
Operating across ASHRAE Climate Zones 2A (Houston Gulf Coast), 2B (South Texas), and 3A (North and Central Texas), HVAC estimating in Texas requires precise equipment selection and sizing verification. Our takeoffs reflect compliance with the International Mechanical Code (IMC), ASHRAE 90.1 energy performance criteria, and the International Energy Conservation Code (IECC 2021) as adopted across Texas municipalities.
Drawings, Specifications, Schedules & Addenda Audit
How our estimating team audits contract documents to eliminate scope gaps before bid submission.
Our mechanical estimating process examines mechanical floor plans (M-series), roof equipment layouts, enlarged mechanical room drawings, control schematics, and equipment schedules. We verify design sensible and latent cooling loads against ambient Texas summer design conditions (ASHRAE 1% dry bulb and coincident wet bulb). We audit Division 23 specifications for RTU curb requirements, vibration isolation, duct sound attenuation, and factory vs field testing scopes.
Preconstruction Workflow for Texas Bids
Our step-by-step preconstruction estimating process tailored for commercial subcontractors.
Equipment Schedule & Spec Review
Auditing RTU, chiller, AHU, boiler, and VRF equipment schedules against Division 23 specifications, verifying electrical characteristics and curb details.
Plan-Based Equipment & Piping Quantification
Counting packaged units, terminal boxes, exhaust fans, and measuring hydronic/refrigerant pipe runs on screen with color-coded trade layers.
Texas Labor Calibration
Adjusting labor units for commercial tilt-wall crane lifts, multi-story mechanical room rigging, and competitive Texas open-shop or union labor environments.
Comprehensive Excel Bid Package
Delivering editable Excel workbooks with equipment tags, capacity schedules, piping bill of materials, and highlighted PDF plans.
What Is Quantified in Our Texas Takeoffs
Every takeoff provides granular, audit-ready line items tailored to Texas trade bidding.
Central Chiller & Boiler Plants
Air-cooled chillers, water-cooled centrifugal/screw chillers, cooling towers with variable frequency drives, primary/secondary condenser water pumps, plate-and-frame heat exchangers, and condensing boilers.

High-efficiency variable-air-volume (VAV) packaged rooftop units (RTUs), energy recovery ventilators (ERVs), dedicated outdoor air systems (DOAS), and commercial split heat pump systems.
Variable Refrigerant Flow (VRF/VRV)
Heat recovery outdoor units, multi-tenant branch selector boxes, indoor cassette/concealed ducted fan coils, and factory-certified refrigerant piping joint networks.
Air Distribution & Terminal Devices
VAV terminal boxes with electric or hot water reheat coils, fan powered boxes (FPBs), sound attenuators, fire/smoke dampers, and architectural linear slot diffusers.
Exhaust & Ventilation Systems
Commercial kitchen exhaust hoods with UL-listed grease duct, hazardous battery room exhaust, parking garage carbon monoxide exhaust fans, and lab fume hoods.
Building Automation Systems (BAS / DDC)
Itemized sensor counts, DDC terminal controllers, VFD interfaces, motorized control valves, enthalpy economizer dampers, and central control head-end integration.
Texas Commercial Project Types We Support
Commercial estimating workflows tailored to the dominant construction sectors across Texas.
Itemized Material Quantities & Bill of Materials
We quantify every mechanical equipment item directly from schedules and floor plan layouts, providing complete model designations, tonnage, CFM capacities, electrical characteristics (voltage/phase), and curb/mounting requirements. Your procurement department receives an organized schedule ready for equipment rep pricing.
Regional Texas Labor Productivity Hours
Our HVAC labor hours are derived from standard MCAA mechanical productivity metrics, broken down by equipment rigging, setting, piping tie-in, duct connection, and commissioning support. We calibrate labor to both competitive open-shop and union labor environments (UA Local 100, Local 211, Local 286).
Commercial Estimating Challenges in Texas
Key engineering and site conditions that impact commercial hvac estimating takeoffs and bid margins.
Extreme Summer Peak Cooling Loads
High ambient temperatures across Texas demand multi-stage rooftop units, oversized condenser coils, and high-efficiency economizers.
Heavy Dehumidification & DOAS Sizing
Gulf Coast humidity requires dedicated outdoor air systems (DOAS) with energy recovery wheels, reheat coils, and insulated condensate lines.
Rooftop Wind Restraints & Structural Curbs
Texas gust wind speeds require heavy-duty structural roof curbs, vibration snubbers, and certified tie-down hardware.
