HVAC ESTIMATING EXPERTISE
SEliminate Bidding Errors With Exact Sheet Metal Weight, Piping & Equipment Quantities.
Bidding commercial HVAC duct networks, complex hydronic piping, or multi-zone VRF systems requires exact geometrical quantification and duct sizing breakdown. Miscalculating sheet metal weight gauges, missing linear feet of internal acoustic liner, underestimating hydronic pipe fittings, or failing to cross-reference equipment schedules can result in severe budget overruns and eroded contractor margins. Archixen delivers fast, reliable, and highly detailed HVAC quantity takeoffs directly from your mechanical blueprints.
Our HVAC estimating team utilizes industry-leading digital software (PlanSwift, Bluebeam Revu, and On-Center On-Screen Takeoff) to quantify rectangular, spiral, and flexible ductwork in both surface area (sq. ft.) and metal weight (lbs/tons) categorized by gauge (18ga–26ga). We trace refrigerant piping, chilled/hot water supply lines, and condensate drains while itemizing dampening devices, diffusers, grilles, VAV boxes, and major mechanical equipment.
Delivered entirely online in organized, fully editable Excel spreadsheets with color-coded Bluebeam plan markups, our takeoffs allow mechanical contractors, fabricators, and suppliers to apply custom labor fabrication rates and material pricing instantly. Submit more mechanical bids with complete confidence in your numbers.
