Five Star HVAC Services, Inc.

Paul was efficient, polite, and careful with our property. Hopefully he is also a 5-star diagnostician. Update—-the job was completed today and Paul is my hero. After doing the installation he patiently reviewed everything with me and throughly tested the work. Care was taken with our home at all times. He is a great tech and a pleasure to deal with. I was also impressed that the manager of the install department came with him to review the project before starting. Five star is totally organized re scheduling, alerts, and arriving on time. The best!!! Five stars for Five Star.

I can describe this company and its technicians in four words: professional, knowledgeable, customer-obsessed, and accountable. I am confident that all of their technicians are highly competent, but I would like to specifically single out and express my gratitude to Pawel and Sergio for the phenomenal service they have provided to my unit over the past year. I live in a high-rise building in downtown Chicago with an in-unit, all-electric HVAC system. For several years, this system had been a bane of my existence, plagued by numerous electrical issues caused by years of inadequate maintenance, improper wiring, and the installation of cheap, unsuitable components by other contractors. Last year, a supposedly experienced contractor from another company installed a thermostat and a relay and

Our boiler died during the holidays, leaving our tenants without heat. Tom Kucharski and Victoria (office) at 5-star are so professional and got us the estimate quickly and their’s was the best price we received. Tom and his crew were clean, thorough, and they stayed working extra hours to get it done quickly knowing that the temperatures were freezing at night. The inspector said the newly installed boiler looked perfect! I’m having 5-star do the annual maintenance moving forward for all our HVAC needs.

Five star is the best heating company on the planet, let alone in the city of Chicago. I've known the owner Mark for a very very long time. We've done business together and I would recommend them for anything related to Unico heating cooling you name it hot water. These guys are the deal. Every technician is smart, reliable professional, but Mark runs a company the way a heating company should be because he's seen over the years. What not to do by other contractors and he's usually the guy who has to go in and fix them anyways 🙂 top notch service top notch people highly highly recommended and I'm a guy who's been in the industry for 30 years

Excellent service—responsive, reliable, and they stand behind everything they install. We’ve trusted FiveStar with multiple systems (Unico, high-efficiency boiler, furnace, heat pumps, humidifiers, and more) and wouldn’t hesitate to recommend them.
