This family-owned company gives their customers a personal touch plus professional respect for boundaries. It's not easy to find this combination! I am a landlord with tenants in office settings and industrial complexes. Windy City Air Conditioning & Heating maintains the HVAC for all my properties. Their response time is amazing! But most important to me is that they make repairs with the appropriate amount of information communicated with tenants, never causing confusion or other problems. Their communication with me is likewise targeted to my financial control over the environment and repairs or replacements they would recommend. I have a lot of respect for their appreciation of the difference. Windy City Air Conditioning & Heating is the best of both worlds! Highly recommend!
