Serving Darien, IL
HVAC Services Darien, IL
Heating, cooling, and emergency HVAC repair from a trusted local contractor. Based in Justice, IL – serving Darien and the western suburbs.
Your HVAC Contractor Serving Darien
Darien sits at the crossroads of I-55 and I-355, with residential neighborhoods stretching from Cass Avenue east toward Lemont Road. Homes in the Farmingdale and Hinsbrook subdivisions were largely built in the 1970s and 1980s – meaning many of the original HVAC systems are well past their expected lifespan or running on their second replacement.
New Comfort Heating and Cooling provides full HVAC services in Darien, IL – from emergency furnace repair to complete AC replacement. We’re based in Justice, a quick ride down I-55, and our technicians are in the Darien area regularly.
HVAC Services We Provide in Darien
Furnace Repair & Replacement
Darien’s winters are no joke. When your furnace fails, we diagnose and repair all brands the same day. If the system is beyond repair, we size and install a replacement matched to your home.
AC Repair & Installation
Humidity near Waterfall Glen makes summer air feel heavier. We repair, recharge, and replace AC systems to keep your Darien home cool and properly dehumidified all season.
24/7 Emergency HVAC
Furnace out on a freezing night? AC dead during a heatwave? We answer the phone live 24/7 and dispatch a technician to your Darien home immediately – no voicemail, no waiting.
Seasonal Tune-Ups
Darien’s sharp temperature swings between seasons wear on HVAC equipment fast. A fall furnace checkup and spring AC tune-up catch failing parts before they leave you without heat or cooling.
Why Darien Homeowners Trust New Comfort
Darien stretches from the Waterfall Glen Forest Preserve on the south to Ogden Avenue on the north. Homes along 75th Street and in the subdivisions off Clarendon Hills Road range from split-levels built in the 1970s to newer construction from the 2000s. Each has different ductwork, different insulation, and different system needs.
We’re not a national chain. We’re a local HVAC contractor based in Justice with over 13 years of hands-on experience in the western suburbs. Our NATE-certified technicians know the common system types in Darien homes and arrive with the parts most likely needed.
Every job comes with transparent pricing before work starts, honest recommendations, and before-and-after documentation. If a repair makes sense, we repair it. We don’t push replacements to pad a bill.
HVAC Services Darien Split-Levels and Raised Ranches Need
A large share of Darien homes are split-levels, bi-levels, and raised ranches from the 1970s and 1980s. They are practical houses, but one furnace and one AC often have to serve three or four levels at once. That is why so many Darien homeowners tell us the bedrooms are hot in July while the lower level stays chilly.
Warm air rises to the top floor, cool air sinks to the family room, and the original ductwork was rarely balanced for central air. An HVAC contractor who only swaps equipment will not fix that. The fix is in the airflow: adjusting balancing dampers, adding a return on the upper level, upgrading to a variable-speed blower, or adding zoning.
For a single problem room – a bonus room over the garage or a sunroom off the back – a ductless unit is often the cleanest answer. Our HVAC services in Darien start with measuring temperatures and airflow on each level, so the recommendation fits how your house actually behaves.
Our Work
Real work by New Comfort Heating and Cooling
Replacing a Second- or Third-Generation Furnace in Darien
Many Darien homes are on their second or even third furnace since they were built. When it is time to replace it again, the job is about more than the box. Closet and utility-room installs like the one shown here need careful planning for venting, the gas line, the return, and access for future service.
Moving from an older 80% furnace to a high-efficiency model changes the venting. The new furnace vents through PVC pipe, and if it used to share a chimney with the water heater, that chimney may now be too large for the water heater alone. We check it on every furnace replacement so exhaust gases go outside where they belong.
We also pair every heating installation with a combustion test and a reminder to keep working carbon monoxide alarms on each level. The EPA explains the health risks of carbon monoxide if you want the background.
Summer Storms, Power Surges and Darien Air Conditioners
Summer thunderstorms roll across DuPage County regularly, and short power blips are hard on air conditioners. A surge can damage the control board, capacitor, or contactor, and restarting a compressor before pressures settle can trip the breaker or strain the motor.
After an outage, set the thermostat to off, wait several minutes once power returns, then turn the cooling back on. If the outdoor unit hums without the fan spinning, shut it off and call for AC repair – running it that way risks the compressor. A surge protector at the outdoor disconnect is an inexpensive add-on worth asking about.
Muggy August weather near the forest preserves also means your AC has to remove a lot of moisture. A correctly sized system that runs longer cycles does that far better than an oversized one that cools fast and shuts off.
40-Year-Old Ductwork and Smart Thermostats for Commuters
Ductwork installed in the 1970s and 1980s has had decades for tape to dry out and joints to loosen. Leaky ducts pull dusty air from crawl spaces and attics and lose heated or cooled air before it reaches the rooms. ENERGY STAR notes that duct sealing can improve comfort and efficiency, especially in older homes.
Darien has plenty of commuters on I-55 and I-355. If the house sits empty all day, a programmable or smart thermostat can ease off while you are gone and bring the temperature back before you get home. We install and set them up so the schedule matches your routine – see our tips on thermostat installation.

+
Heat rises and cool air sinks, and the original ducts in most 1970s split-levels were not balanced for central air. We measure airflow on each level, then adjust dampers, add a return, or recommend zoning or a variable-speed blower. Often the fix costs far less than new equipment.
+
Sometimes it can as-is, and sometimes it needs work. Undersized returns and leaky joints are common in older Darien homes and can keep a new system from reaching its rated efficiency. We inspect the ducts during the estimate and tell you exactly what, if anything, needs to change.
+
Yes. Townhomes and condos often have equipment in a closet, attic, or on a small pad, with tight access. We repair and replace furnaces and air conditioners in these settings and coordinate around shared walls and association rules as needed.
+
Choose an HVAC contractor who diagnoses before quoting, explains the options in plain language, and stands behind the work. Ask whether they offer both furnace repair and AC repair, 24/7 emergency service, and free estimates on replacements – we do all three.
