Hard freezes around Chicago can crack coils and stress heat pumps, so make sure your tech checks defrost cycles and backup heat before winter.

In Chicago, a HVAC tech job driven by system size, SEER rating, and ductwork condition generally runs $6,000–$14,000. This is a general range — always get itemized written quotes.

Once a year per system is the standard recommendation — cooling in spring, heating in fall. Regular tune-ups catch small issues early and keep manufacturer warranties valid.
In moderate climates a heat pump can heat and cool efficiently from one system and often lowers energy bills, though very cold regions may still want backup heat. Costs vary with size and efficiency, so ask for a payback estimate.
