HVAC & Mechanical Takeoff Services for Contractors
Accurate ductwork, equipment, and piping takeoffs — hire full-time, part-time, or project-based remote estimator for your mechanical bids.
CSI Division 23 (HVAC / Mechanical)
Hire a dedicated remote HVAC / Mechanical estimator — full-time, part-time, or project-based. CSI Division 26 electrical takeoffs.
Mechanical systems are some of the most expensive line items in any commercial bid, and a miscounted duct run or missed equipment spec can cost you the job — or worse, cost you after you’ve won it. ABLE Estimating gives you dedicated remote estimators who specialize in HVAC and mechanical takeoffs, so every bid reflects the real scope of the job.
CSI Division 23 breakdown (real line items)
- Ductwork quantities by size and type (supply, return, exhaust)
- Equipment schedules (RTUs, AHUs, chillers, boilers, VAVs)
- Piping takeoffs (hydronic, refrigerant, condensate)
- Insulation quantities
- Diffusers, grilles, and registers
- Controls and thermostats (where scoped)
Full-Time Remote Estimator
A dedicated HVAC estimator working exclusively for your company, full workweek, every week. Ideal for solo HVAC contractors bidding consistently on HVAC and HVAC Data Center jobs who want one person who learns your standards and software over time.
Part-Time Remote Estimator
A dedicated HVAC estimator for a set number of hours or days per week — perfect if your HVAC / Mechanical bid volume doesn't justify a full-time hire yet, but you need more consistent support than one-off electrical takeoffs.
Project-Based Remote Estimator
Not ready to commit to a dedicated hire? Send us a single set of Mechanical plans and get a takeoff back — no onboarding, no long-term commitment. Many Mechanical contractors start with a project or two before moving to part-time or full-time estimator.
