Our Take on Five Star HVAC Services, Inc.
Five Star holds 4.9 from 446 Google reviews, read September 16, 2026, and its Unico and SpacePak experience is valuable in Chicago's historic housing.

About Five Star HVAC Services, Inc.
Adding air conditioning to a Gold Coast greystone or a North Shore house built a century ago usually means working around plaster walls, narrow chases and finished ceilings. Five Star HVAC Services, Inc. has built a specialty around exactly that. The company works from Elston Avenue in the Mayfair area, and its website says it has more than 25 years of HVAC experience, with a focus that includes historic homes in Chicago, the Gold Coast and the North Shore suburbs.
The headline service is small-duct high-velocity cooling. Five Star installs Unico and SpacePak systems, which use two-inch flexible tubing that can snake through tight spaces, so older homes get central air without large ducts. It also installs Mitsubishi Electric ductless systems and works on Peerless boilers, which are common in older Chicago houses. Residential and light commercial jobs are both on the list. The website advertises free estimates on new installations and replacements, and financing is available.
Loyal repeat customers show up throughout the reviews. One longtime client praised a technician named Sergio for his knowledge and for explaining issues and options clearly. Another wrote at length about Richie and Sam, calling them reliable, hardworking and professional. Mark, Juan, Paul, Tom and Ivan are also named.
Posted hours are 8 AM to 6 PM on weekdays and 8 AM to 5 PM on Saturdays, with Sundays closed. The website does not advertise 24/7 emergency service, and license numbers and warranty terms are not published.
Who it suits: owners of historic and vintage homes who want central air installed with minimal disruption, and anyone with a boiler that needs a knowledgeable technician. Who it suits less well: people needing help overnight or on a Sunday.
Before signing, ask to see photos of similar high-velocity installs, how the outlets will be placed in each room, and what warranty covers labor.
