Local Service Across Uptown, South Park & Park Ridge Neighborhoods
Uptown is the part of Park Ridge most people recognize first. The Pickwick Theatre has stood there since 1928, with its 100-foot tower marking the center of the city’s shopping, dining, and event district. Nearby residential streets mix historic homes with newer construction and plenty of long-established properties.
South Park has its own commercial center along South Park Avenue, while Village Green mixes residential and retail activity. The Dee Park area around Oakton Avenue has another concentration of established homes, and farther west the city reaches toward Iroquois and Chippewa Woods.
Those local differences matter because the mechanical systems can vary just as much as the neighborhoods. One call may involve an older boiler or steam system. The next may be a central AC replacement, a drain issue, a sump pump, or a whole-home comfort upgrade.
Solving HVAC, Plumbing & Indoor Air Quality Issues in Park Ridge
Problem: Older Park Ridge homes can have aging boilers, steam systems, central AC equipment, and plumbing components that require different approaches depending on the property.
Solution: Deljo provides heating, cooling, plumbing, and indoor air quality services designed around the existing equipment and conditions in each Park Ridge home.
Problem: Established homes may have different comfort needs, including humidity control, filtration, purification, zoning, or systems that were added after the home was originally built.
Solution: Deljo provides whole-home indoor air quality and comfort-control services, including filtration, purification, humidification, dehumidification, thermostats, and zoning solutions.
Problem: Plumbing issues can range from a clogged drain or water heater problem to older piping, repeated drain problems, sewer issues, or larger repiping projects.
Solution: Our plumbing services cover emergency plumbing, drain cleaning, water heaters, pipe repair, sewer lines, repiping, sump pumps, flood control, and other plumbing needs throughout Park Ridge.
AC Repair & Cooling Upgrades Across Park Ridge
Cooling calls around Park Ridge are not all the same. Homes near the Dee Road Metra station, Uptown, and the Higgins Corridor can include everything from older central AC systems to properties where cooling was added later. Some postwar homes were built without central air, which still creates retrofit needs today.
For AC service, Deljo provides:
A homeowner replacing an existing central system may be looking at a straightforward upgrade. Another property may need a different approach because the house was never designed around central cooling in the first place.
Taste of Park Ridge brings food booths, entertainment, a kids’ zone, and the Chamber Business Expo to Prospect and Summit Avenues every July. It is one of the city’s biggest summer events, and it also lands right in the middle of the season when AC problems tend to get a homeowner’s attention fast.
“I’m one of the hottest days ever Marek and Luis Installed an air-conditioning unit. They were efficient worked the entire time they were here left their work area in great shape. What an asset they both are to Deljo Heating, Cooling and Plumbing!”

Furnace, Boiler & Steam Heat Service in Park Ridge
Park Ridge has a real mix of heating equipment. Central furnaces are common throughout the city, while boilers and steam systems are still found in older areas near Uptown and Dee Park. That makes heating service here more varied than simply repairing or replacing furnaces.
Heating work can include:
- Heating installation
- Heating repair
- Heating maintenance
- Furnace service and replacement
- Heat pump service
- Boiler service
The right answer depends on what is already in the home. Some properties need a furnace repair or replacement. Others call for boiler service, steam system work, or a broader upgrade that includes zoning or newer controls.
Hodges Park sits in the middle of the Uptown civic area and hosts Concerts in the Park through the summer. That part of Park Ridge is surrounded by some of the city’s more established residential streets, which is one reason we still see older heating systems mixed in with newer equipment.
“Marek Slomba was the senior technician in charge of my complicated furnace replacement and his work is excellent! And he is pleasant and a terrific whistler. The more difficult the work, the better the whistling. He is highly recommended. In addition to being an excellent installer, he is a kind person who listened to my concerns and understood my needs.”

Whole-Home Air Quality & Comfort Controls in Park Ridge
Some Park Ridge homes need more than a furnace or AC replacement to feel right throughout the house. Larger older properties, including homes with natural wood and plaster interiors, can benefit from better humidity control, filtration, purification, or zoning.
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
- Thermostats
- AC coil and condenser cleaning
Whole-home humidifiers and dehumidifiers give homeowners more control over indoor moisture. Smart thermostats and zoning can also make it easier to manage different parts of the house without relying on one setting for every room.
Centennial Park and Aquatic Center is one of Park Ridge’s main recreation hubs, while the western edge of the city reaches toward Iroquois and Chippewa Woods. The residential areas around those landmarks are another reminder that Park Ridge is not one uniform neighborhood, and comfort needs can vary just as much as the homes themselves.
“Punctual and explained everything he was doing and recommending in great detail.”

A Local Service Area With Distinct Park Ridge Neighborhoods
Uptown is the part of Park Ridge most people recognize first, with the Pickwick Theatre, shopping, dining, and events. South Park has its own commercial center along South Park Avenue, while Village Green mixes residential and retail activity.
The Dee Park area around Oakton Avenue has another concentration of established homes, and farther west the city reaches toward Iroquois and Chippewa Woods. The Higgins Corridor and Dee Road areas add another mix of residential properties and local activity.
Centennial Park and Aquatic Center, Hodges Park, the Golden Triangle, the Pickwick Theatre, and the Park Ridge Farmers Market are among the local destinations that help distinguish different parts of the community.
These are the areas homeowners recognize. They also show why Park Ridge is not one uniform neighborhood and why heating, cooling, plumbing, and indoor air quality needs can vary throughout the city.

Job Locations and Reviews
Replaced the existing soil piping and removed and replaced the 75-gallon gas-fired storage water heater, reconnecting the gas supply with a shutoff valve, the flue venting, and the potable water supply lines. Verified the new unit and connections were secure and operating properly.
Inspected the existing cast iron soil stack and associated drain assembly to evaluate replacement needs. Observed active rust staining and weeping at the lower coupling joint near the cleanout, along with flaking paint and surface corrosion on the stack, indicating deterioration of the line. Documented the condition of the stack, branch fittings, and surrounding overhead framing to support replacement scoping.
Performed a seasonal heating tune-up and inspection on a 15-year-old furnace, including replacement of the dirty pleated air filter with a new clean filter. Evaluated the existing Aprilaire humidifier control, which is mounted on the supply duct and has loose, spliced low-voltage wiring that should be secured and properly terminated before further humidifier operation or installation.
Performed an on-site evaluation for a full HVAC system replacement, with the air handler located in the attic requiring telescopic ladder access. Recorded equipment and duct dimensions, documented the existing wall-mounted digital thermostat, and gathered the measurements and system details needed to prepare the full-system estimate.
Performed annual maintenance on the furnace/boiler system, including removal and inspection of the humidifier evaporator pads, which showed heavy mineral and debris buildup and were serviced or flagged for replacement. Conducted combustion safety verification with a calibrated CO analyzer at the appliance, recording 11 ppm with a 12 ppm max, within acceptable limits, and confirmed the intermittent ignition system and surrounding electrical connections showed no visible corrosion, damage, or breakage.
Returned with the correct replacement sensor, wiring harness, and warranty control board to complete the sold repair. Installed the new components, verified proper connections and sensor operation, and confirmed the system returned to normal operation.
Evaluated a non-operational boiler over 15 years old and found the expansion tank has failed, with the system requiring a major rebuild to restore operation. Inspected the boiler, piping, flue, and electrical connections, and documented system conditions with photos. Given the age of the unit and the extent of repairs needed, boiler replacement is recommended.
Responded to a no-cool call on a residential split-system air conditioner and connected a manifold gauge set to the outdoor condensing unit to evaluate system refrigerant pressures and locate the source of a refrigerant leak at a service valve. The condenser's side access panel was opened to inspect internal components and wiring, and the leak was addressed at the valve to restore the system's refrigerant circuit integrity. The condensate drain line and surrounding unit area were also checked and found draining properly.
Responded to a no-heat call on a Model PF-80-NRV2 boiler and inspected the system, including the expansion tank, pressure gauge connection, and combination temperature/pressure gauge. Found system pressure low at the expansion tank with the boiler temperature sitting near its low end, and noted corrosion and mineral buildup on the boiler top surface and gauge fitting. Verified operating pressure and temperature readings to diagnose the no-heat condition.
Performed diagnostic service on a Carrier boiler for a complaint of uneven heating, with the unit still operating. Inspected the thermostat subbase and verified the wiring at the terminals (Rc, Rh, W1, C, and Y/G connections) to confirm proper control signal to the boiler. Reviewed system operation and zone heat distribution for balancing and circulation issues.
Returned to the site to replace the boiler temperature sensor following system drain-down. Drained the boiler to the required level, removed the faulty temp sensor, installed the new sensor, and refilled and purged the system. Verified proper operation at the control panel, with boiler temperature reading 183°F on the display and normal heating cycle confirmed.
Performed an on-site estimate for a full-system replacement of a 1999 furnace and outdoor condenser unit, with easy access to all equipment. Measured and documented the dimensions of the space for proper sizing and load calculations, and inspected the existing condenser, noting debris buildup at the base and grime on the attached housing.
Responded to a no-heat call on a 10+ year old gas furnace and inspected the burner assembly, inducer motor, gas valve, and wiring, finding heavy dust and grime buildup throughout the cabinet, likely from recent construction activity. A borescope inspection of the internal components revealed visible rust and corrosion along the heat exchanger/coil fin surfaces, and the unit's age and condition were documented with photos for further evaluation.
Responded to a complaint of the boiler operating briefly and then shutting down, and inspected the control cabinet, burner assembly, and ignition/flame sensing components. Found the flame sensor/ignitor assembly and burner section affected by soot and carbon buildup, with congested wiring and insulation debris in the control panel, and serviced the ignition components and burners to restore reliable flame proving and sustained operation.
Performed annual maintenance on the gas-fired forced-air furnace, humidifier, and tankless water heater, including inspection of the burner assembly, gas piping, and condensate drainage, and replacement of the 16x25x1 return air filter. Removed and inspected the tankless water heater's inlet strainer for debris, with no visible frost, rust, or cracking noted on the heat exchanger or internal components. Replaced the humidifier water panel (#35) and documented service findings on-site.
Responded to a call back for a thermostat error code that appeared upon furnace startup and a non-operational cooling system. Inspected the furnace through the burner sight glass, confirming stable blue flame characteristics, and verified supply air temperature at the unit with a pocket thermometer (96.2°F). Evaluated the thermostat error and cooling system operation to restore proper heating and cooling function.
Evaluated an R22 split system that had lost its refrigerant charge and provided a full system replacement estimate, since R22 is phased out and a recharge is neither cost-effective nor practical. Inspected the indoor gas furnace and air handler setup, including the burner assembly, inducer motor and blower, gas valve, pressure switch, PVC venting and condensate lines, insulated flex ductwork, and electrical connections, and found no frost, ice, rust, or visible damage. Documented all equipment conditions with photos to support the replacement recommendation.
Removed the existing boiler and installed a new Prestige high-efficiency condensing boiler with a digital control panel, connected to the existing Navien unit, with new copper supply and return piping, brass isolation valves, circulator pumps, and an expansion tank. Routed and sealed PVC venting, reconnected the gas and electrical supplies, and verified proper system operation with no leaks.
Responded to a no-cool call on a 2007 R22 split system and connected a digital refrigerant manifold to assess system pressures. Static readings of approximately 6.8–6.9 psig on both sides indicated a complete loss of refrigerant charge, and a subsequent pull-down check showed a vacuum on the low side, confirming a leak and an inoperable cooling cycle. The system requires leak detection and repair, evacuation, and recharge, with the aging R22 platform noted as a factor in the repair-versus-replacement decision.
Completed full HVAC system replacement including furnace, air conditioning unit, evaporator coil, humidifier, and digital thermostat. System commissioning verified proper static pressure readings at 3.92" w.c., and new Aprilaire thermostat was programmed and tested for optimal climate control operation.
