What We See in Winnetka Homes
There is a lot of variety packed into Winnetka. Indian Hill is known for large lots and architecturally significant estates. Hubbard Woods combines residential streets with shopping, dining, community events, and its Metra station. East Winnetka extends toward Lake Michigan and Centennial Park, while West Winnetka is primarily residential with a strong concentration of pre-war homes.
Architecture is a major part of the local landscape as well. George Washington Maher, Walter Burley Griffin, Howard Van Doren Shaw, and David Adler all designed homes in Winnetka. Crow Island Elementary School, designed by Eliel and Eero Saarinen in 1940, is another major architectural landmark and a National Historic Landmark.
For us, those differences mean one thing: look at the house, understand the system, and solve the problem that is actually there.
Solving HVAC, Plumbing & Indoor Air Quality Issues in Winnetka
Problem: Boilers and steam heat remain a meaningful part of the Winnetka service picture. More than half of the village’s housing was built before 1939, and more than 75% predates 1970. Older estate homes, including properties around Indian Hill and West Winnetka, are among the places where these systems remain especially relevant.
Solution: Central furnaces are also common, so heating service here is far from limited to boilers. Homeowners considering replacement can also look at high-efficiency equipment, zoning, and upgraded controls.
Problem: A plumbing problem does not care whether you are headed to the Winnetka Music Festival, spending the afternoon near Centennial Park, or simply trying to get through the morning at home. When a drain, water heater, pipe, fixture, or sewer line needs attention, the priority is getting the system working correctly again.
Solution: Water heater replacement, fixture upgrades, and drain service are all important parts of the Winnetka plumbing market. Larger projects can extend to repiping, sewer work, flood control, and other system improvements.
Problem: Larger Winnetka homes can create another challenge: getting the whole house to feel the way you want it to feel. Estate-scale properties make zoning and whole-home controls especially relevant because different levels or areas of a house may need more precise management.
Solution: Filtration, purification, humidity control, thermostats, and zoning give homeowners options beyond replacing the furnace or AC unit alone. These systems can be considered together when the goal is better control across the entire property.
Air Conditioning Repair & Installation in Winnetka, IL
An AC call near Hubbard Woods may take us into a very different property from one near the estates of Indian Hill. Central air conditioning is common throughout Winnetka’s single-family housing, while high-efficiency replacement is an option for homeowners ready to update older equipment.
Deljo handles:
Hubbard Woods is one of Winnetka’s most recognizable neighborhood centers, with boutique shopping, dining, merchant events, and Metra service. Farther east, Centennial Park brings beach access, tennis courts, and recreation to the Lake Michigan side of the village.
Those settings are different, and the homes around them can be different too. That is why we start with the existing cooling system instead of approaching every Winnetka AC call with the same answer.
“Gabe was wonderful! I called them when my tenants AC went out during the heat wave, and they were able to get over and get everything sorted extremely quickly. He was very thorough and told me everything that was going on even though I was not physically there. Really appreciate the great work!”

Winnetka Boiler, Furnace & Heating Services
Boilers and steam heat remain a meaningful part of the Winnetka service picture. More than half of the village’s housing was built before 1939, and more than 75% predates 1970. Older estate homes, including properties around Indian Hill and West Winnetka, are among the places where these systems remain especially relevant.
Heating work can include:
- Boiler service
- Furnace repair
- Furnace installation
- Heating maintenance
- Heat pump service
- Heating system replacement
Central furnaces are also common, so heating service here is far from limited to boilers. Homeowners considering replacement can also look at high-efficiency equipment, zoning, and upgraded controls.
Indian Hill gives this part of the article a distinctly Winnetka setting. The neighborhood sits along the western edge of the village and is known for larger lots, estate properties, and significant residential architecture. Indian Hill Club is another longstanding landmark in this part of the community.

Whole-Home Air Quality & Comfort Controls in Winnetka
Larger Winnetka homes can create another challenge: getting the whole house to feel the way you want it to feel. Estate-scale properties make zoning and whole-home controls especially relevant because different levels or areas of a house may need more precise management.
Deljo can help with:
- Air duct cleaning
- Aeroseal
- Indoor air quality inspection and testing
- Air filtration
- Purifying ionizers
- Air purifiers
- Whole-home humidifiers
- Whole-home dehumidifiers

- AC coil and condenser cleaning
Filtration, purification, humidity control, thermostats, and zoning give homeowners options beyond replacing the furnace or AC unit alone. These systems can be considered together when the goal is better control across the entire property.
That whole-home approach is particularly relevant in areas such as Indian Hill, where large residential properties are part of the neighborhood character.

Life Around Winnetka Extends Well Beyond the House
Service calls take us into the residential side of Winnetka, but the community has plenty of recognizable activity outside those neighborhoods.
The Winnetka Music Festival turns the downtown area into a two-day summer concert destination and draws approximately 5,500 people, primarily from Winnetka and nearby North Shore communities. Hubbard Woods hosts merchant programming, and the Winnetka Park District offers activities throughout the year.
Centennial Park gives residents access to the lakefront, while Crow Island Elementary School represents another side of the village’s architectural history. Together with Indian Hill, Hubbard Woods, East Winnetka, and West Winnetka, these places give different sections of 60093 their own identity.
Need HVAC or Plumbing Service in Winnetka?
You may be calling about an old boiler, an AC system that suddenly stopped working, a plumbing repair, or a house where one thermostat is no longer giving you the control you want. The address might be near Hubbard Woods, Indian Hill, Centennial Park, or somewhere between the lakefront and Winnetka’s western edge.
“Gabe was wonderful! I called them when my tenants AC went out during the heat wave, and they were able to get over and get everything sorted extremely quickly. He was very thorough and told me everything that was going on even though I was not physically there. Really appreciate the great work!”

Replaced the failed draft inducer motor assembly and pressure switch on the gas furnace, correcting the pressure switch/inducer fault that was preventing proper venting and ignition. Reconnected and secured the wiring to the new components, then verified proper inducer operation, pressure switch closure, and burner ignition with a stable flame during the heating cycle.
Performed annual maintenance on five furnaces and five humidifiers, inspecting blower assemblies and control circuit board wiring, and servicing humidifier components, including a water panel heavily scaled with mineral deposits. Media filters were not installed per the agreement, as the customer is supplying them, and replacement filters were verified on hand in storage. Noted loose, tangled wiring in the furnace cabinet and residue on the cabinet floor for further evaluation.
Performed scheduled maintenance on two gas-fired furnaces and one gas-fired boiler, including cleaning and inspection of the burner assemblies, draft inducers, flue and vent piping, and control components. Verified safe operation, proper combustion venting, and condensate drainage on all units, with no leaks or issues identified.
Completed full HVAC system replacement, installing three furnaces, three condensers, three evaporator coils, two humidifiers, three thermostats, and one dehumidifier. Condensing units were set on level composite pads with refrigerant lines, insulation, and electrical disconnects connected, and thermostat wiring was terminated at new controls with removal of the old units. System operation was verified, with existing wall damage noted at the thermostat locations.
Performed scheduled maintenance on the rooftop unit (RTU) and boiler, replacing two 12x20x1 filters and servicing the washable filter. Inspected the air handler compartment, finding the filter lightly loaded and moisture present in the drain pan area, and removed a dirty mesh screen component from the system for cleaning/inspection.
Removed the existing attic furnace and installed a new Carrier horizontal gas furnace, reconnecting the flue venting, supply plenum, and flexible ductwork with foil-faced sealing and insulation wrap. Installed a new 4x25x1 pleated filter, restored the electrical connection, and cleared old filter material, foil tape scraps, and debris from the work area upon completion.
Performed an on-site evaluation for replacement of a 12-year-old furnace exhibiting multiple operational issues, with the findings confirmed by technical support. Inspected the supply plenum and low-voltage control wiring, took duct measurements for proper equipment sizing, and documented the condition of the exterior condensing units, which showed no visible frost, rust, or damage. Provided a replacement recommendation based on the equipment's age and the combined deficiencies identified.
Returned to the site and replaced two pressure switches on the furnace, installing the new switches with the existing wiring and hose connections reconnected and secured. Also completed scheduled maintenance on two furnaces, with all components inspected and no damage, frost, or rust noted.
Returned to address a failed pressure switch condition and diagnosed a faulty integrated furnace control board. Removed the access panel, disconnected and labeled the wiring harness and low-voltage connections, and replaced the control board with a new OEM unit. Reconnected all terminals, restored power, and verified proper control board operation and system functionality.
Responded to a callback for a furnace failing to operate following recent maintenance and performed diagnostic testing on the unit. Measured supply air temperature of 113.1°F at the ductwork using a digital thermometer and inspected the surrounding sheet metal, noting minor surface corrosion near the measurement point.
Installed a new 75-gallon natural gas water heater with a Bradford White tank, connected the flue to the existing draft hood and venting, and fitted a new expansion tank on the supply piping to manage thermal expansion pressure. Updated the shutoff valves on the water and gas connections, then verified proper operation, leak-free fittings, and safe venting.
Performed scheduled preventive maintenance tune-up on two 8-year-old furnaces and two humidifiers under the maintenance agreement, including inspection of heat exchangers, burners, ignition components, and safety controls, along with cleaning and servicing of humidifier components. Accessed equipment via the attic stairway and verified all systems for proper operation and airflow.
Inspected the upstairs attic-installed furnace and identified a cracked heat exchanger, rendering the unit unsafe for continued operation. Assessed attic access, framing clearances, and existing flexible ductwork to determine replacement requirements, and prepared a replacement estimate for the upstairs furnace.
Responded to a no-heat call on a Lennox gas furnace and performed a diagnostic evaluation of the unit. A borescope inspection of the internal heat exchanger area revealed heavy rust and corrosion at the opening, indicating deterioration of the heat exchanger. No external frost, rust, or visible damage was found on the cabinet, venting, or condensate piping. Findings were documented with photos for repair or replacement recommendations.
Performed scheduled maintenance under the service agreement, including cleaning and checks on two furnaces and the whole-house humidifier, along with a general system safety inspection. Measured supply air temperature (approximately 80°F) and identified torn foil-faced duct insulation, which was sealed with foil tape to restore the vapor barrier and thermal integrity.
Responded to a callback for a water leak following prior boiler repairs. Inspection revealed standing water on the basement floor around the hydronic expansion tank and surrounding piping, with Triangle Tube replacement parts currently unavailable. Documented the leak with photos, and the system remains pending the availability of the required parts to complete the permanent repair.
Responded to a no-heat call on a Carrier Infinity Touch system displaying fault code 180 (Zone 1-4 communication failure) and a system fault on the bottom unit. Inspected the zone control board, including terminal connections, wiring, capacitors, and MOV, and found no visible burn marks, corrosion, or physical damage. Verified low-voltage wiring integrity and communication bus connections between the zone control and the thermostat to address the communication fault.
Replaced two dielectric unions and the P-trap beneath the basement sink, restoring proper isolation between dissimilar metals and a watertight drain connection. Pressure-tested the new fittings and verified there were no leaks.
Returned to replace the flame sensor on the furnace. Removed the fouled, discolored sensor assembly with visible residue buildup and installed the new sensor with its mounting bracket, restoring proper flame rectification and reliable burner operation.
Performed scheduled maintenance on two Lennox gas furnaces under the service agreement, including inspection of the condensate drain, PVC venting, refrigerant line, and ductwork connections.
