FREQUENTLY ASKED QUESTIONS

Chicago HVAC Estimating FAQs

How does the Chicago Electrical Code (Title 14E) impact electrical takeoffs?

Title 14E prohibits NM cable (Romex) and severely restricts MC cable. All branch wiring must run in EMT or rigid steel conduit with steel boxes, which we calculate with precision bending, coupling, and hanger counts.

How do you account for Chicago union trade wage agreements and productivity?

We calibrate labor using current IBEW Local 134, Pipefitters Local 597, and Sheet Metal Local 73 collective bargaining agreements, with logistical factors for high-rise material hoisting and winter heating.

What standards and codes govern HVAC Estimating estimating in Chicago?

In Chicago, HVAC Estimating estimating is governed by Chicago Building Code (Title 14), Chicago Electrical Code (Title 14E — Mandatory EMT/Rigid Conduit), 2021 IECC with IL Amendments, MWRDGC Stormwater alongside CSI Division 23 (Heating, Ventilating, and Air Conditioning) standards. We calibrate all material quantities, equipment sizing thresholds, and labor hours to satisfy Chicago municipal inspectors.
