Wilmette has some of the oldest and most substantial housing stock we work on. Homes here were frequently built before central air conditioning existed, and many still heat exactly the way they were designed to — with a boiler and radiators. That makes Wilmette a specialist job rather than a routine one.
We're a family-owned company that has served Illinois since 2015, and Wilmette is east of our Des Plaines base, on the North Shore. Every repair is a flat price you approve before we start, carried out by licensed, insured, background-checked technicians and backed by a full warranty.
The Homes We Work On in Wilmette
Wilmette's established neighborhoods are dominated by early-twentieth-century construction — brick Tudors, colonials, and substantial period homes from roughly the 1900s through the 1930s — on mature, tree-lined streets near Lake Michigan.
Steam and hot-water boilers feeding cast-iron radiators remain common, and they are excellent heating systems when properly maintained — even, quiet, and long-lived. The complication is cooling: a house with no ductwork has no obvious path for central air, so adding it means high-velocity small-duct systems, carefully-planned conventional ductwork, or accepting a hybrid arrangement. Older electrical service can also need attention before AC is added.
Problems We See Most Often in Wilmette
Every area has its own recurring faults, driven by when the housing was built and what was installed at the time. In Wilmette, these are the calls that come up again and again:
- Steam and hot-water boilers with uneven heat, air-bound radiators, or failing zone valves
- Period homes with no ductwork where adding central cooling needs a real design
- Electrical service that needs upgrading before central air can be added
- Lake-influenced summer humidity making older homes feel warmer than the thermostat reads
- Third-floor and converted attic spaces that neither the boiler nor a retrofit AC reaches well
Commercial HVAC & Refrigeration in Wilmette
Wilmette's commercial work centers on the village's independent restaurants, cafes, and specialty food retail, including the shops around Plaza del Lago. That means reach-in refrigeration, prep tables, display cases, and smaller walk-ins — often in period buildings where equipment access is genuinely tight.
For any of it, downtime is lost money and — with refrigeration — a food-safety exposure, so we treat commercial calls as priority work and carry the common parts needed to finish most repairs on the first visit.
Seasonal Considerations in Wilmette
Proximity to Lake Michigan moderates the temperature extremes but keeps summer humidity high, and older homes with radiator heat have no ductwork through which to dehumidify. That's why so many Wilmette comfort complaints are really about humidity rather than temperature — and why the right answer is often dehumidification rather than more cooling capacity.
Whatever the season, the goal is the same: get your Wilmette home or business comfortable again quickly, and be straight with you about what it needs.

Wilmette HVAC — Frequently Asked Questions
Can central air be added to an older Wilmette home with radiators?
Usually, but it's a design question rather than a catalog purchase. High-velocity small-duct systems are made for exactly this situation, and conventional ductwork is sometimes possible through closets and attic space. We'll assess the house — including whether the electrical service needs upgrading first — and give you real options with real costs.
Some of my radiators stay cold. Can you fix that?
Yes, and it's one of the more common calls we get from Wilmette. Cold radiators usually come down to trapped air, a failed vent or zone valve, or an imbalance in the loop. It's normally a straightforward repair — not a reason to replace the boiler.
What is your service call or diagnostic fee?
The diagnostic fee is $79 residential / $149 commercial, and it's waived in full when you proceed with the repair.
Do you charge by the hour?
No — we use a fixed-price-per-repair model. You get a straightforward, upfront price for labor and parts before any work begins.
Do you service window AC units or mini-splits?
Our AC service covers central, ducted, and commercial systems only — not window units or mini-splits.
Are your repairs warrantied?
Yes. Most parts carry a 12-month warranty, and labor is warrantied 30+ days depending on the repair.
