“A 5 star recommendation for experts who know what they are doing.”
“HeatCool (4511 N Kedzie, Chicago) has been our trusted HVAC service provider for 10+ years.”
HeatCool (4511 N Kedzie, Chicago) has been our trusted HVAC service provider for 10+ years. High rise living makes HVAC, humidity and moisture challenging. The proper solution is almost custom designed for the environment since every building is different (age, glass good/bad for HVAC, etc) . Once designed, the Service Team supports the system….they are a 10 Star ⭐️ Team. Sam is like an HVAC surgeon and really puts the homeowners mind at ease. The front end (Theresa), service techs (Sam, Alex) and designer/owner (John) creates the A-Team. Jim & Mary Chicago

“Having recently purchased a stand alone home (as opposed to condo) the team from Heatcool has been very helpful to me.”
Having recently purchased a stand alone home (as opposed to condo) the team from Heatcool has been very helpful to me. John has given me nuggets of information, that a home owner should know… needless to say… I had no idea about any of the functions of any HVAC systems. I’m glad to have them on my team!

Excellent cleaning/maintenance job on our through-wall ACs by Marlon and Sebastian. They were extremely thorough, explained things clearly, gave us helpful tips, and were very personable and kind. We’ll ask for them by name for next year’s maintenance.

Sameer was the consummate professional who pre-alerted me of his arrival and was punctual. He was thorough in his assessments of my AC system and offered solid advice on its upkeep. An added bonus was his warmth and the kindness of his Spirit. I would highly recommend his services.

“Sam was an excellent customer service representative.”
Sam was an excellent customer service representative. He explained what he was doing and why. He knew about the pipe valve with a basket and flushed it out very well. He drained the bottom of the hot water tank and checked for leaky valves. I liked him and I felt like he really knew what he was doing.

Sam spent the entire day at our place installing a new air conditioning system. It was a HOT day and never once did he seem put out. And by the end of the day my place was cool! Also, 5 stars for his helper, who worked non stop, all day long! They both deserve a raise!

We have been using HeatCool for many years and love working with John Freson and his team! Their attention to our needs and budget plus superb installation and service make them a 5 star rating for us. And they are a local, family-owned company. Being part of their annual Club Service for continuing customers is the best money we've ever spent.
