Worth knowing: The I-270 corridor data center build-out (Montgomery + Frederick counties spillover from the substantial Northern Virginia data center cluster — Loudoun County alone hosts ~70% of global internet traffic via Ashburn data center concentration) drives substantial mission-critical HVAC demand. Senior data center HVAC technicians with 24/7 on-call capability and chiller plant operations expertise clear $115-175K w/OT. Hospital facility cooling at Hopkins + UMMS + MedStar + Adventist requires ASHRAE 170 ventilation compliance, isolation room positive/negative pressure management, and medical-air system maintenance — drives premium HVAC specialty pay at $95-135K. Constellation Energy's three nuclear power generation operations in MD (Calvert Cliffs Lusby + retired Susquehanna) plus Domino Sugar refinery (Baltimore — uses substantial ammonia refrigeration in raw sugar handling) drive industrial HVAC specialty demand. The 2025 No Tax on Overtime federal deduction applies through 2028 — at $20K OT premium produces ~$4,400 federal + potential ~$950 MD = ~$5,350 cumulative. The MD combined effective rate at journeyman comp ($110K, Montgomery County 3.20% piggyback) is ~7.95%.
