I purchased my Chicago condo in 2008. My HVAC unit was at the end of its life at that point, and the building manager recommended only two companies to perform work on the building’s HVAC system. One of those companies was HEATCOOL, whom I called, and I’ve never felt a need since that first call to switch to any other company.
The HEATCOOL technicians worked on my old HVAC unit and charged it with Freon for as long as they could, and then I finally had to purchase a new unit. The tech had a small, physically-challenging space to perform his installation within, but he did it with amazing skill and minimal adverse consequences.
Everyone at HEATCOOL has always been professional, knowledgeable, sympathetic and very helpful every time I’ve called or emailed them, especially John and Valerie. If any work performed by their technicians has not been to my satisfaction, John and Valerie have made sure that it was done until it met my expectations. I would recommend HeatCool to anyone.
