Evanston sits right on Lake Michigan in Cook County, with a housing mix that ranges from vintage masonry homes to modern apartments near Northwestern. That variety means no two heating and cooling jobs look quite the same, and we treat each one on its own terms. Whether you need a furnace tune-up, a boiler repair, or a full AC replacement, we show up ready to do honest work.
Evanston has some of the oldest housing stock in the north suburbs, including century-old Victorians, classic Four-Squares, and sturdy vintage masonry homes alongside the condos and apartments clustered around downtown and the university. These homes were built long before central air was standard, so heating and cooling systems are often a patchwork of original and added equipment. Working on them takes patience and respect for how the house was put together.
Many older Evanston homes still run on steam-boiler and radiator heat, while others were converted to forced air decades ago. Common issues we see include aging boilers that need service, ductwork retrofits squeezed into homes never designed for them, uneven temperatures from floor to floor, and humidity problems in lakefront properties close to the water. Knob-and-tube wiring and tight chases can complicate installs, so we plan carefully before we start.
We are a family-owned company, and we treat Evanston homeowners the way we would want our own neighbors treated: straight answers, clear pricing, and no pressure to buy more than you need. Being based in nearby Glenview means we can get to your home quickly when something goes wrong. When we recommend a repair or replacement, we explain why, so you can make the call with full information.

We serve homeowners across every part of Evanston, including these areas.
The downtown core is dense with condos, vintage apartment buildings, and mixed-use properties near the Metra and CTA lines. Space is tight and systems are often shared or compact, so we focus on solutions that fit small mechanical rooms and rooftop units. We handle both single-unit work and building-wide tune-ups here.
Homes close to Lake Michigan deal with high humidity that can strain cooling systems and invite mold or musty air. We help lakefront owners with proper dehumidification, AC sizing, and ventilation so the house stays comfortable even on the muggiest summer days. Many of these are larger vintage homes with original heating layouts.
This south-side area is full of classic single-family homes, many with steam boilers and radiators still in service. We keep those older heating systems running and, when owners are ready, plan careful conversions or forced-air retrofits. Zoning upgrades are popular here for homes with hot upper floors and cool basements.

Ask us anythingYes. A lot of Evanston's older housing still runs on steam-boiler and radiator systems, and we service, repair, and maintain them. If you are weighing whether to keep your boiler or convert to forced air, we will walk you through the honest tradeoffs for your specific home.
Often, yes. Many century-old Evanston homes were never built for ducts, so we look at retrofit ductwork or ductless mini-split systems depending on the layout. We assess your home first and recommend the approach that adds the least disruption while keeping you comfortable.
Homes near Lake Michigan take on extra moisture, and an undersized or aging AC system struggles to pull it out of the air. We can check your equipment, recommend proper dehumidification, and make sure your system is sized right for the humidity loads near the lake.
