Why Des Plaines Homeowners Choose Fireside Heating & Air Co. of Chicago
We’ve been in enough Des Plaines basements to know which ranch homes on West Howard Street still have their original 1958 ductwork, and which split-levels near Algonquin Road got new windows but never had their furnace combustion air recalculated. That kind of specific knowledge matters when you’re deciding whether to repair a 20-year-old Lennox or start over with something sized correctly for your house as it exists today.
Our technicians are background-checked, uniformed journeymen who put on shoe covers without being asked. They carry parts for nine major brands including Goodman, Rheem, and York, so we’re not making a second trip because we guessed wrong on a board or a pressure switch. Every job is backed by our 90-Day Done Right Promise - in writing, no paperwork to file, no arguing if something isn’t right. The price we quote is the price you pay.
Homeowners in Des Plaines call us because we’re still here when the job is done. Not a franchise truck with a rotating crew. Not a voicemail tree at 2 a.m. A live person, every time.
HVAC Services We Offer in Des Plaines
AC Repair & Installation
Summer humidity in Des Plaines isn’t a dry heat, and lake-effect moisture pushes latent loads higher than many systems can handle. We repair all makes and models, and when replacement makes more sense, we size for your actual house - not the square footage on a tax record. Learn more about our AC Repair & Installation in Des Plaines.

Heating & Furnace Service
Polar vortex events here can hold below −15°F for days straight. That stress cracks heat exchangers and burns out inducer motors on furnaces that were already marginal. We inspect, repair, and replace heating systems with equipment rated for the real conditions we face. Learn more about our Heating & Furnace in Des Plaines.

Heat Pump & Mini Split Systems
Modern cold-climate heat pumps have changed the math for Des Plaines homeowners, especially in homes with flood-damaged basements where relocating the mechanical room makes sense. Ductless mini-splits solve the problem of additions and converted attics that never had ductwork to begin with. Learn more about our Heat Pump & Mini Split in Des Plaines.

Air Quality & Ventilation
The FAA-funded sound-insulation program left hundreds of Des Plaines homes with tight envelopes and no mechanical ventilation. We install ERVs and HRVs as part of our Air Quality & Ventilation - Des Plaines services to bring fresh air back into balance, and we size humidity control for the actual latent load your house generates.

Emergency & Commercial HVAC
Our phones are answered by a live person 24 hours a day, 7 days a week, including holidays. No heat in January, no cooling during a July heat advisory - we dispatch trained technicians, not call-center scripts.

Neighborhoods We Serve in Des Plaines

- River Road area - Post-flood mechanical room relocations and elevated furnace installs
- Downtown Des Plaines - Mixed-age housing, from 1920s frame homes to mid-century brick ranches
Why Des Plaines’s Climate & Housing Affect HVAC
Des Plaines built out fast in the 1950s and 1960s, and the housing stock shows it. Ranch and split-level homes dominate, most with basement mechanical rooms and ductwork sized for the oversized, low-efficiency furnaces of that era. When we retrofit a modern variable-speed system into one of these houses, the ductwork almost always needs sealing, resizing, or both. The equipment is only as good as the delivery system, and the delivery system in a 1962 Des Plaines ranch was designed for a different machine entirely.
The flooding along the Des Plaines River in 2013 and 2017 created a recurring category of work we don’t see in Park Ridge, IL or Mount Prospect: furnaces and air handlers submerged in basement mechanical rooms, replaced with flood-elevated installs on platform framing or relocated to first-floor closets. We know the local code requirements for those relocations, and we’ve done enough of them to quote accurately without surprises.
Then there’s the O’Hare flight-path factor. Homes in the 60018 overlap zone received triple-pane windows and added insulation through FAA programs, tightening the envelope without anyone checking whether the furnace still had adequate combustion air or whether the house had any mechanical ventilation at all. We regularly find humidity trapped at 65% or higher, CO2 climbing above 1,000 ppm, and homeowners who think they need a bigger air conditioner when what they actually need is an ERV paired with a correctly sized system. It’s a specific problem set that comes from knowing this particular city.
The climate itself is unforgiving. Polar vortex events test heat exchangers and inducer motors to failure. Summer humidity from regional lake-effect patterns adds latent cooling load that surprises transplants from drier climates. Your HVAC system in Des Plaines works harder and faces more variable demands than systems fifty miles west.

FAQs About HVAC in Des Plaines
Most furnace repairs in Des Plaines run between $180 and $420 for standard parts like ignitors, capacitors, or flame sensors. Major repairs such as heat exchanger replacement or control board failure typically range from $850 to $2,400. The age of Des Plaines’s housing stock means we see more failed inducer motors and cracked heat exchangers during polar vortex events than in newer suburbs. Call (833) 983-1671 for a diagnostic and exact quote - estimates are free.
In Des Plaines, this usually traces to one of three causes: an undersized system, a system charged incorrectly for the latent humidity load, or a house with sound-insulation upgrades that tightened the envelope without adding mechanical ventilation. We measure actual airflow, refrigerant charge, and duct leakage before recommending any fix. Call (833) 983-1671 and we’ll sort out whether it’s equipment, ductwork, or ventilation.
We give straight talk on this. If your furnace is over 18 years old, uses a cracked heat exchanger, or has needed two major repairs in three years, replacement is usually the better spend. For newer systems or single failures, repair makes sense. We don’t sell equipment you don’t need. Call (833) 983-1671 for an honest assessment with no pressure.
Yes, for most calls placed before early afternoon. Our technicians are dispatched from the Chicago area, and Des Plaines is typically reached within 30 to 45 minutes during normal hours. Emergency calls at night or on weekends are handled by our on-call crew, with phones answered by a live person - never a voicemail tree. Call (833) 983-1671 any time.
Do not restart a flooded furnace. Water damage to gas valves, control boards, and the heat exchanger creates real safety hazards including combustion problems and carbon monoxide risk. In Des Plaines, we’ve handled many post-flood replacements along the river corridor, and we know the local code for elevated or relocated mechanical rooms. Call (833) 983-1671 for safe inspection and replacement options.

What Des Plaines Customers Say
"The thermostat had been miswired by whoever installed it, so the heat strips were running with the AC. He found it in a few minutes and probably saved me a fortune on the next few bills."
- Nicole Fletcher"Blower motor on a twelve year old furnace. He gave me the honest math on repair against replace and did not push me toward the bigger ticket."
- Paige Hoffman"The maintenance plan is actually worth it. They turn up twice a year and the last visit caught a refrigerant leak before it became a July disaster."
- Kurt Anderson
