How accurate are the material takeoff and cost calculations?

Calculations are grounded in industry-standard engineering formulas (such as compacted density multipliers, ASTM standards, and CSI MasterFormat divisions), with customizable local material unit costs and compaction waste factors.

What waste allowance factor should be added to material orders?

For commercial and residential trade installations, standard engineering practice recommends including a 5% to 10% material waste and compaction contingency factor.

Can I export these takeoff sheets for client bidding?

Yes, you can export full itemized material schedules and bid breakdowns directly to CSV or printable takeoff summaries.

EPA AIM Act Compliance & ASHRAE Standard 15 Exemption

As the EPA mandates an 85% phase-down of hydrofluorocarbons (HFCs) by 2036 under the AIM Act, commercial operators face rising costs and safety complexities with mildly flammable A2L (R-32, R-454B) or toxic A3/B2L refrigerants. Solid-state magnetocaloric systems use inert water-glycol fluid circulating through solid magnetic beds, completely bypassing refrigerant leak detectors, mechanical purge rooms, and machinery room ventilation requirements.
