What We Do
Our Services
AC Repair
Our truck-stock guarantee means every service vehicle carries over 200 common AC parts. If we cannot fix it in one visit, the diagnostic fee is waived on your follow-up appointment.
Furnace Repair
Every furnace repair includes a complimentary carbon monoxide safety check with a calibrated detector — because a cracked heat exchanger can endanger your family even after the heat comes back on.
HVAC Installation
Every installation includes a Manual J load calculation and a post-install commissioning report — documented proof that your system is correctly sized, charged, and airflow-balanced for maximum efficiency and comfort.
HVAC Maintenance
Our Comfort Club membership locks in your maintenance visits at today's rate for as long as you remain a member — and includes priority emergency dispatch so members never wait behind the general queue.

What Our Customers Say
“Furnace died during the polar vortex in Naperville. Our maintenance plan with Summit meant we jumped the queue and had a tech at the door in 2 hours. Neighbors waited 3 days with other companies.”

“Old radiator system converted to forced-air in our Evanston Victorian. Summit designed a system that preserved our original woodwork while actually keeping every room warm. Exceptional craftsmanship.”

“New high-efficiency furnace in Schaumburg. The old one was 80% efficient, new one is 98%. Gas bills dropped by a third and the house heats evenly for the first time.”
