Built for the way Chicago HVAC calls actually come in

Chicago works HVAC contractors at both extremes: polar-vortex cold that turns a furnace failure into a true emergency, and humid summers that push AC hard. Calls spike during a winter storm or heat wave, often in the middle of the night, and the city's older housing stock keeps boiler and furnace work steady. Whoever answers the after-hours call books it.

Peak demand in Chicago runs December through February and June through August, and that is exactly when calls overflow and go to voicemail. Thermoi picks up every one, qualifies the caller, books the routine jobs, and pushes true emergencies straight to your on-call technician, so a busy season stops meaning lost work.
