Heating & Furnace repair in Prospect Heights typically runs $150-$700, with most service calls completed same-day when you call (833) 983-1671.

Call (833) 983-1671

We’ve been driving to Prospect Heights since 2018, long before the Countryside subdivision filled in and Elmhurst Road became the main corridor it is today. That matters when your furnace quits at midnight on a February night with wind chills below -20°F. We answer the phone live, 24 hours a day, every day of the year. No voicemail tree. No “leave a message and we’ll call back tomorrow.” A real person takes your call, dispatches our nearest technician, and gives you an arrival window we stand behind. Most of our Heating & Furnace calls in ZIP 60070 are handled in a single visit because our trucks are stocked for the brands we know dominate this area.

Why Fireside Heating & Air Co. of Chicago Is Prospect Heights’s Preferred Heating & Furnace Company

Forty-two years in this business means we’ve watched Prospect Heights grow from a quiet alternative to Mount Prospect into the established community it is today. We’ve serviced the original furnaces in those first ranch homes off Palatine Road, replaced them with 80% AFUE units in the 1990s, and now install 96% AFUE condensing furnaces for homeowners who plan to stay another twenty years. That continuity matters. We know which subdivisions have the original ductwork, which streets see the worst winter winds off the plain, and which propane setups freeze regulators in deep cold.

Our reviews from Prospect Heights customers consistently mention the same things: we show up when we say, we quote one price and stick to it, and we don’t leave until the job’s done right. The 90-Day Done Right Promise backs every repair and installation in writing. If something isn’t right, we make it right. No paperwork to file, no arguing, no runaround.

Response time to Prospect Heights averages under 90 minutes during normal hours from our Chicago base. For emergency no-heat calls, we’re typically on Elmhurst Road or Palatine Road heading your way within the hour. We don’t subcontract to out-of-area crews who need GPS to find Countryside or need to look up Cook County permit requirements. That’s local knowledge you can’t fake.

Our Heating & Furnace Services in Prospect Heights

Furnace Repair

Furnace repair in Prospect Heights runs $150-$700 depending on the part and the hour. The most common winter call we get in the split-levels off Elmhurst Road and Palatine Road isn’t a broken heat exchanger or failed gas valve. It’s a furnace that runs, but can’t push enough heat to the upper half-level while the lower level stays cold. Homeowners call us back two or three times for “no heat upstairs” before we find the real problem: inadequate return-air pathways in the original 1960s duct design. We fix the root cause, not just the symptom. Our trucks carry ignitors, gas valves, blower motors, and control boards for Lennox, Goodman, Rheem, and York systems, so most repairs finish in one trip.

Furnace Repair

Furnace Replacement

Here’s the truth about furnace replacement in Prospect Heights that out-of-area contractors won’t tell you: your ducts probably weren’t designed for a modern 96% AFUE furnace. Prospect Heights developed primarily in the 1960s-1970s as a more affordable alternative to neighboring Mount Prospect and Arlington Heights, leaving the city with a dense concentration of ranch and split-level homes whose original single-zone duct systems were sized for first-generation forced-air furnaces - not today’s high-efficiency equipment. When homeowners upgrade to modern 96% AFUE furnaces, the old undersized ductwork causes static pressure problems and comfort complaints, making duct evaluation and rebalancing a near-mandatory part of every system replacement here. Last January, our crew responded to a no-heat call on a split-level in the Countryside subdivision off Elmhurst Road. The homeowner had installed a high-efficiency Lennox furnace that kept short-cycling; we found the original return drop was undersized for the new blower, causing static pressure over 0.8″ w.c. We upsized the return and added a secondary balancing damper to the lower level - one trip, done right. We handle the Cook County mechanical permit and inspection as part of every replacement. That’s not optional in ZIP 60070, and contractors who skip it leave you exposed.

Furnace Replacement

Furnace Tune-Up

Our $89 seasonal tune-up catches the problems that turn into midnight emergency calls. In Prospect Heights, that means checking heat exchanger integrity on furnaces pushing 20-30 years, testing gas pressure at the valve (critical for propane setups on rural-acreage properties with long drives off Elmhurst Road), and measuring temperature rise across the coil. We also inspect blower amp draw - oversized blowers in retrofitted systems strain motors designed for gentler airflow. The tune-up includes filter replacement sizing check and written condition report. Schedule in September or October before the first hard freeze.

Furnace Tune-Up

Heat Exchanger Inspection & Replacement

A cracked heat exchanger is a safety issue, not a repair to postpone. In Prospect Heights’s older housing stock, we see heat exchanger failures most often in furnaces installed in the 1980s and 1990s that have cycled through thousands of Chicago winters. Our combustion analyzers detect CO levels at the ppm, and we show you the camera footage of any crack or corrosion. If replacement is needed, we quote the full job upfront - heat exchanger, labor, and any associated venting modifications for high-efficiency operation. No surprises.

Trusted Brands We Service in Prospect Heights

We train our technicians as journeymen on nine major brands: Carrier, Trane, Lennox, Goodman, Rheem, York, Daikin, Bryant, and American Standard. In Prospect Heights, we see Lennox and Goodman most frequently in the Countryside-area homes, with Rheem and York common in the ranch subdivisions off Palatine Road. Our warehouse stocks the failure-prone parts for these systems - ignitors, flame sensors, pressure switches, blower motors - so we’re not ordering overnight and making you wait. That’s the difference between a local company that knows this market and a dispatcher sending whoever’s available from thirty miles out.

Common Heating & Furnace Problems We See in Prospect Heights Homes

  • Split-level airflow imbalance. In split-levels built before 1985, winter overheating of upper half-levels with chill below is common - driving repeat service calls that actually stem from inadequate return-air pathways, not equipment failure. We measure static pressure and redesign return drops rather than replacing another furnace that won’t fix the problem.
  • Short-cycling on new high-efficiency installs. Homeowners upgrade to 96% AFUE furnaces without duct modifications, then wonder why the system runs constantly without reaching temperature. The old ductwork can’t move the air volume the new blower demands. We evaluate every replacement for this.
  • Propane regulator freeze on rural-acreage properties. Properties with long service drives off Elmhurst Road and beyond often have underground propane tanks. Subzero wind chills - routine in Prospect Heights’s exposed flat-plain location - freeze regulators and cause intermittent gas supply. We test gas pressure under load and can recommend regulator insulation or relocation.
  • Failed ignitors in original 1980s furnaces. The silicon nitride ignitors in early high-efficiency furnaces have a 10-15 year lifespan. Many Prospect Heights furnaces are on their third or fourth. We stock multiple grades and test flame rectification before we leave.

What Prospect Heights Customers Say

Trusted by homeowners across Prospect Heights and surrounding areas.

★★★★★

"Ductwork in the attic had a disconnected run dumping cold air into the insulation. He found it, resealed it, and a bedroom that was always hot is normal now."

Hector Guzman · Verified customer
★★★★★

"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 · Verified customer
★★★★★

"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."
