They came on time and replaced my 60 year old Dunkirk Blue Circle boiler with a Dunkirk DXL-205K. They even fixed a problem with one of my radiators that wasn’t heating. The work looks great and they did a good clean up.

“The AC went out in the middle of a heat wave.”

The AC went out in the middle of a heat wave. My tenants contacted a different contractor who gave me a $25,000 quote and couldn't explain to me what was broken or how it would be repaired. I live out of state and called the team from Windy City Mechanical to provide a 2nd opinion. They came out the next day and diagnosed the issue then gave me all the information I needed to understand what went wrong and also make a decision on the best repair options get the system up and running<br>Saved me $15,000! It was a great experience and highly recommend them.

“​I cannot recommend Tom and the team at Windy City Mechanical highly enough.”

​I cannot recommend Tom and the team at Windy City Mechanical highly enough. Replacing the entire HVAC system in a historic home is an intimidating project, but they handled it flawlessly. Instead of just offering a quick fix, Tom partnered with me to find a lasting solution that would genuinely serve as an asset to the house. They kept me in the loop and confident throughout the entire process. From great communication to fantastic workmanship and an invaluable customer experience, Windy City exceeded my expectations. You won't go wrong trusting them for a new system or routine maintenance.

“These people from phone contact to technician are the best ever .”

These people from phone contact to technician are the best ever . And I am 71 years old, nice to have a honest company to work with. 95° a/c went out. From time I called to time it was fixed about 4 hours total. And didn't charge me an arm and a leg. Wish I could give them more than 5 stars.

“The company came to my home as scheduled and on time.”

The company came to my home as scheduled and on time. The owner was terrific, he spent a lot of time with me explaining my options and solutions. He made me feel comfortable and confident in his company. He gave me the best price I had received after months of getting quotes from other companies. The owner and his crew (Brian and George) showed up and did a VERY professional job.these guys thrive on being professional, knowledgeable and meticulous. They walked me through the entire install.once the job was completed they cleaned up all debris. I'm very satisfied with this company and would recommend them to any that needs hvac service. Definitely a 5 star company.
