Heating, Ventilating and Air Conditioning (HVAC/ Mechanical Estimate)

Mechanical bids don’t get picked apart on the big-ticket equipment. They get picked apart on the hundred small line items around it a damper type, a hanger spacing, a controls point nobody counted. HVAC is one of the most component-dense trades on any project, and a takeoff that stops at “ductwork” and “equipment” is a takeoff that’s already missing a third of the real cost.

Our Division 23 HVAC estimating services are built to go past the basic takeoff. We cover every measurable, cost-driving component of the mechanical system ductwork, equipment, piping, controls, insulation, and accessories and deliver execution-ready estimates that support accurate bidding, smart procurement, and confident project planning from day one.

Ductwork Measured the Way It’s Actually Fabricated and Installed

• Supply, return, and exhaust ductwork (rectangular, round, spiral)
• Sheet metal gauges by pressure class
• Duct fittings: elbows, transitions, offsets, take-offs, end caps
• Volume control dampers, fire/smoke dampers
• Access doors, turning vanes, splitters
• Flexible duct connections
• Hangers, supports, seismic bracing
• Shop vs. field fabrication breakdowns

Quantities are provided in linear feet, square feet, weight, and piece count — aligned with how your shop fabricates and your crew installs, not a single blended duct-footage number.

HVAC Equipment Every System Type, Counted and Specified

• Rooftop units (RTUs)
• Air handling units (AHUs)
• Fan coil units (FCUs)
• Exhaust, supply, and makeup air fans
• Chillers, boilers, heat pumps
• VRF / VRV indoor and outdoor units
• Energy recovery ventilators (ERVs / HRVs)
• Split systems and packaged units

HVAC Piping Systems Sized, Not Guessed

• Chilled water piping
• Hot water heating piping
• Condenser water piping
• Refrigerant piping (VRF / split systems)
• Gas piping for mechanical equipment
• Condensate drain piping
• Pipe sizes by diameter and material
• Valves (isolation, balancing, control)
• Fittings, flanges, unions
• Pipe supports and anchors
• Expansion joints and specialties

HVAC Insulation & Lining Matched to System Requirements

• Duct insulation (internal & external)
• Piping insulation (hot & cold systems)
• Acoustic duct lining
• Vapor barriers and jacketing

Thickness, material type, and system-specific requirements are clearly identified for every assembly not assumed from a “typical” spec that may not apply to your project.

HVAC Controls & Automation

• Thermostats and sensors
• Control panels and controllers
• Actuators and dampers
• Building Management System (BMS) interface points
• Low-voltage wiring allowances

Labor Hours & Installation Costs Priced for Real Job Conditions

• System type and complexity
• Commercial vs. residential installation
• New construction vs. renovation
• Accessibility and ceiling heights
• Union or open-shop conditions (as applicable)

Labor units reflect realistic site productivity, not generic industry averages because a rooftop unit set on a two-story commercial building doesn’t install at the same pace as one set on a single-story renovation, and your bid should reflect that difference.

HVAC Accessories & Miscellaneous Items

• Diffusers, grilles, and registers
• Louvers and intake/exhaust hoods
• VAV boxes and terminal units
• Hangers, anchors, sleeves, firestopping
• Equipment pads and curbs
• Start-up, testing, and balancing allowances

Ready-to-Bid Proposal Estimates

• Organized line-item cost breakdown
• Material, labor, and equipment separation
• Marked-up plans showing takeoff scope
• Assumptions, inclusions, and exclusions
• Excel or PDF formats suitable for GC submission

Why Mechanical Contractors Value Our HVAC Estimates

• Confirmed quantities, measured strictly per plans and specs  not a rule-of-thumb sizing
• Itemized material lists for supplier pricing and ordering, so procurement starts on solid numbers
• Fewer RFIs, fewer change orders, better execution: because the scope was right before the first duct section shipped
• A bid proposal ready to submit to GCs, with no reformatting needed on your end

A mechanical estimate this detailed doesn’t just help you win the bi it protects your crew from discovering a missing damper or an uncounted hanger run halfway through installation.

Our HVAC Estimating Process

1. Plans & Specification Review : We review mechanical drawings and specifications to fully understand ductwork, equipment, piping, controls, insulation, and accessory scope.
2. Detailed Takeoffs & Pricing:  Every component is measured and cross-checked, then priced using realistic labor units and current U.S. market rates.
3. Bid Proposal Delivery: You receive a clear, bid-ready HVAC estimate that supports competitive pricing, proper material ordering, and confident execution ready to submit to the GC.

Bid Your Next HVAC Project With Confidence

Whether it’s a single rooftop replacement or a full mechanical system for a new commercial building, an estimate built at this level of detail is what separates a competitive bid from a lucky one.
