HeatCool Service Co

I worked with HeatCool at my business location for the last several years. When my condo also needed AC service I asked the custodial crew and they enthusiastically recommended HeatCool. Turns out they've been working in my building for many years and were familiar with the systems. An added bonus. They explained what was going on and the work to be done, billed promptly. There were no hidden costs. Professional and a delight to work with. We won't go anywhere else!

John came to inspect at the furnace, air conditioner, and water heaters. He was beyond knowledgable about everything. He was able to explain the problems and show us what was happening. He was honest and straightforward about everything. The price was more then fair to inspect everything. Theresa set up the appointment easily and was in communication the entire time. I would work with the company again in a second. Highly recommended.

We had our entire HVAC system replaced by HeatCool. Everything about the whole process was smooth and easy. I have already recommended them to my friends. If you need your furnace worked on quickly and without any hassle, HeatCool is who you need to have do your work!

Koky and his team were fast and efficient! They showed up a day early and brought us AC during the miserable hot and humid Chicago summer days. I highly recommend them!

Heat Cool saved me from an $8k bill by repairing an AC unit that other, larger outfits said couldn't be repaired and had to be replaced. The Heat Cool techs were very knowledgeable and repaired the unit within a few hours. I highly recommend.

My apartment needed some MAJOR work done and this company was outstanding in every way. John Freson, who runs his team of courteous and professional contractors, is extremely thorough. He explained every process clearly so that even a layman like myself could understand not only the work being done, but the costs attached. I was so impressed by his honesty and meticulousness that I went through him to get additional work (plumbing, wallpapering, etc.) done as he has a wide variety of contractors to do various jobs. Heat Cool gets my highest recommendation!

John and Oscar came out to our place in Rogers Park to replace our furnace. These guys are awesome! They're friendly, fair on price and went above and beyond in service. Our new furnace is working like a charm, and the guys went around to make sure all the vents in our condo were working properly. After they left, the furnace room was cleaner than how they found it. Great guys and great service!

HeatCool was great! They worked with us and our landlord to replace both of our in-wall A/C units quickly, just in time for Chicago summer. They gave us a fair quote & they were always friendly and courteous.

I've been a HeatCool customer for 18 years. They've installed space-saving radiators in my kitchen, heating/cooling systems in the attic, hot water heaters, a boiler and chimney liner, and central air conditioning, in addition to doing annual fall/spring servicing of the heating and cooling systems. There's no one I trust more for fair, dependable, knowledgeable service. Thanks John!!!

So after 10 days of sweltering heat in my apartment with NO working A/C, my landlord FINALLY contacted John Freson of HeatCool Service Co. Punctual, responsive enroute and while on-site. I'm a long-time renter. John treated me as if I was paying the bill! Courteous, kind, professional with an explanation of what was wrong and what he fixed. He even did some dog TLC on the way out. A/C working great -- temps dropped inside from 84 degrees to 74 throughout the rest of the day. This is what customer service is all about. Thanks John for your service. I told my landlord that he needs to keep you!
