What North Chicago Customers Say
Heat stopped working on a Sunday night and with temps dropping fast I called JG Cool HVAC. Tech was at my door in under 90 minutes — on a Sunday. Found a failed igniter, had the part on the truck, and fixed it that night. He billed exactly what was quoted. I've told everyone I know about these guys.
I manage 28 units in North Chicago and JG Cool HVAC has been my HVAC service company for over a year. They answer when I call, show up when they say, and never pad invoices. My maintenance headaches dropped significantly. Reliable service for a property manager is genuinely rare — these guys deliver it.
AC went out during a heat advisory in North Chicago with two young kids at home. I was stressed. Called JG Cool HVAC and they had someone out within two hours. The tech found a refrigerant leak, fixed it same visit, and had us cooling by afternoon. Lifesaver. Written price before he started, exactly what we paid. Five stars.
Our North Chicago bakery's cooling system failed on a Friday. I called three companies — two didn't answer, one said Monday. JG Cool HVAC had a commercial tech on site in two hours. He diagnosed the problem, fixed it, and we were operational again before close. Incredible emergency response for a small business. I'm a permanent customer.
Replaced our full HVAC system in North Chicago with JG Cool HVAC. From the sizing assessment to final installation — completely professional. They explained why we didn't need the larger unit another company quoted us and saved us over $800. Installation was clean and on schedule. System runs perfectly. Honest company.
Had persistent allergy issues in our North Chicago home for two years. JG Cool HVAC assessed our air quality, installed a whole-home purifier and UV system, and the difference was noticeable within weeks. Tech was knowledgeable and never pushed unnecessary upgrades. My wife hasn't had a single flare-up since. Worth every penny.
