FAQ

How often should HVAC equipment be serviced in Chicago?

Most homes should plan for AC service in spring and heating service in fall, especially before heavy seasonal demand.

Does maintenance prevent every breakdown?

No maintenance can guarantee that, but it reduces preventable failures and helps catch worn parts, airflow problems, and safety issues earlier.

Can you maintain both furnace and AC systems?

Yes. ChillTech services residential heating and cooling systems, including furnaces, central AC, boilers, ductwork, and thermostats.
