“Exayard measures duct runs faster than our most experienced estimator. We bid on projects we used to pass on.”
“The equipment schedule reader is a lifesaver. No more manually typing in unit specs from the mechanical drawings.”
“Our duct fitting counts are finally accurate. We stopped eating costs on fittings we missed in manual takeoffs.”

How HVAC contractors use AI for estimating
AI takeoff tools trace duct and piping systems from mechanical plans, measuring runs and counting terminals so estimators can focus on pricing instead of scaling.
Reading mechanical plans and equipment schedules
Mechanical plans layer ductwork, piping, and equipment onto floor plans that are already dense with architectural and structural information. AI isolates the mechanical systems and identifies air handling units, rooftop units, split systems, VAV boxes, fan coil units, and exhaust fans from their symbols and tags. It reads equipment schedules to associate each unit with its CFM rating, tonnage, and static pressure requirements. The system parses supply, return, and exhaust as separate systems and traces them back to the equipment they serve — critical context that determines duct sizing and material specifications for each run.
Measuring ductwork and counting terminals
AI traces duct runs from AHUs and rooftop units through mains, branches, and terminals. It measures rectangular duct by length and cross-section, round duct and flex duct by diameter and length, and identifies transitions, elbows, tees, and offsets along each run. Terminal devices — supply diffusers, return air grilles, and linear slot registers — are counted and tagged with their neck size and CFM requirement from the diffuser schedule. The system quantifies duct transitions between sizes, turning vanes in elbows, and volume dampers at branch takeoffs. All measurements are organized by system so estimators can price sheet metal fabrication and flex duct separately.
Quantifying piping and accessories
Beyond ductwork, most commercial HVAC projects include hydronic piping, refrigerant lines, or both. AI measures copper refrigerant piping between condensing units and evaporator coils by diameter and length, including line sets for split systems. For hydronic systems, it traces chilled water and hot water piping from the mechanical room through risers and branch lines to fan coils and VAV reheat coils. Pipe fittings, isolation valves, balancing valves, and flexible connectors are counted along each run. The system also picks up insulation requirements from the specs — fiberglass on chilled water lines, elastomeric on refrigerant piping — so insulation is estimated alongside the piping it covers.
What is HVAC estimating software?
HVAC takeoff software helps mechanical contractors quantify ductwork, piping, equipment, and air distribution devices from mechanical drawings. This includes measuring duct runs by size and type, counting diffusers, grilles, and registers, tallying VAV boxes and terminal units, and extracting equipment schedules for rooftop units, air handlers, and chillers. HVAC takeoffs are among the most complex in construction because mechanical drawings are dense with overlapping systems — supply air, return air, exhaust, hydronic piping, and refrigerant lines may all appear on the same sheet. Manual takeoff requires an estimator to methodically trace each system, which on a large commercial project can take multiple days.
AI-powered HVAC takeoff software like Exayard accelerates this process by recognizing duct symbols, diffuser types, and equipment tags automatically. The AI traces duct runs to calculate linear footage by size, counts air devices by type, and reads mechanical schedules to extract equipment specifications. Instead of spending three days tracing ductwork on a 100,000 square foot building, an estimator can get initial quantities in hours and focus their expertise on pricing, labor, and coordination. Exayard is especially effective for the repetitive counting work — tallying hundreds of diffusers across dozens of floor plans — while leaving the judgment calls on routing and installation methods to the experienced estimator.
