AC went out Friday afternoon in July. ClimateProTech had a tech at our Wicker Park home within 90 minutes and fixed it that same evening. Best HVAC company in Chicago, hands down.

AC repair in Chicago and suburbs typically costs $150–$600. Common repairs like refrigerant recharge run $200–$400; compressor replacements $800–$2,000. ClimateProTech provides a free upfront estimate before any work starts — no hidden fees, ever.
Yes — 24/7, 365 days including holidays. We dispatch from Roselle immediately and typically arrive within 2 hours anywhere in Chicagoland. Chicago's extreme polar vortex winters and hot humid summers mean we treat every breakdown as urgent.
We serve 80+ communities across Cook, DuPage, Kane, and Will Counties — including Naperville, Schaumburg, Aurora, Elgin, Joliet, Bloomingdale, Bartlett, Carol Stream, Hanover Park, Arlington Heights, Palatine, and dozens more. No travel fees within our service area.
Yes. Every ClimateProTech technician holds a valid Illinois HVAC or Electrical Contractor License, is NATE-certified, EPA 608 certified, bonded, and insured. We pull all permits from Chicago and suburban municipalities and schedule inspections — you never touch the paperwork.
Absolutely. We install Level 2 EV chargers (240V) for Tesla, Ford, Chevy, Rivian, and all other EVs across the Chicago suburbs. We handle all permitting and help you apply for ComEd rebates — which can significantly offset your installation cost.
Chicago's climate is brutal on HVAC systems — polar vortex winters and hot humid summers. We recommend a furnace tune-up every fall and AC tune-up every spring. Our annual maintenance plans save money and prevent expensive breakdowns during peak season.
Always. Unpermitted electrical work voids your homeowner's insurance and can cause issues when selling your home. We pull permits on your behalf for every job in Chicago and all suburbs, schedule the inspection, and handle all municipality paperwork.
