Furnace & Heating Repair in Chicago, IL
Fast, safe furnace and heating repair when Chicago temperatures drop — with careful attention to gas and carbon monoxide safety.
A furnace failure during a Chicago cold snap is more than an inconvenience — it can put your family's safety and your home's plumbing at risk within hours. Polar Refrigeration & Air Control delivers fast, thorough furnace and heating repair across Chicago and the suburbs, with a strong focus on the gas and carbon-monoxide safety issues that generic handymen overlook.
Our technicians diagnose the true cause of a no-heat or poor-heat call — whether it's a failed igniter, a cracked heat exchanger, a faulty flame sensor, a bad control board, or a clogged condensate line on a high-efficiency unit. We test, explain, and repair, and we never restart a system we believe is unsafe without correcting the underlying hazard.
From gravity furnaces in century-old Chicago two-flats to modern condensing units in newer suburban builds, we know how the region's heating systems fail and how to get heat back safely and quickly.
Signs Your Furnace Needs Repair
- No heat, or air that never gets warm
- The furnace short-cycles — turning on and off repeatedly
- Yellow or flickering burner flame instead of steady blue
- A carbon monoxide detector alarms (leave and call 911 first)
- Loud banging, rattling, or a delayed 'boom' on ignition
- The blower runs constantly or won't start
- Rising gas bills without a colder-than-usual month
- Burning or musty smells when the heat turns on
Common Furnace Problems in Chicago Homes
The most frequent no-heat calls we run come down to a failed hot-surface igniter, a dirty flame sensor that shuts the burner down for safety, a tripped high-limit switch from restricted airflow, or a clogged condensate line freezing on a high-efficiency furnace. Older units often fail at the blower motor, capacitor, or control board.
The most serious issue we look for is a cracked heat exchanger, which can leak carbon monoxide into your living space. We inspect it on every repair, and if we find a crack, we will not return a compromised furnace to service — your safety comes before a quick fix.
- Igniter, flame sensor, and gas valve replacement
- Heat exchanger inspection and safety condemnation when needed
- Blower motor, capacitor, and control-board repair
- High-efficiency condensate line and drain repair
- Thermostat and zoning troubleshooting
- Venting and combustion-air corrections
Why Carbon Monoxide Safety Matters
Gas furnaces produce carbon monoxide as a byproduct of combustion, and a healthy system vents it safely outside. When a heat exchanger cracks or venting is blocked, that CO can enter your home — and it's colorless and odorless. Every Polar furnace repair includes combustion and safety checks precisely because a heating repair done wrong can be dangerous. We also recommend a working CO detector on every level of your home.
Our Furnace Repair Process
Safety-first dispatch
If you smell gas or suspect carbon monoxide, we tell you to leave and call 911 or the gas utility first. For no-heat calls, we prioritize you during freezes.
Combustion & safety testing
We inspect the heat exchanger, test the igniter, flame sensor, gas valve, and safety controls, and check for combustion and venting problems.
Written repair options
You get an itemized quote and an honest repair-versus-replace assessment, especially if we find a cracked heat exchanger or an aging system.
Repair & safety verification
We complete the repair and confirm safe ignition, proper temperature rise, and correct venting before we consider the job done.
What Affects the Cost
Furnace repair costs depend on which component failed and the age and type of your system. Here are the honest factors that shape the price — no fake flat rates.
The failed part
An igniter or flame sensor is an affordable repair; a control board, blower motor, or gas valve costs more. A cracked heat exchanger usually means replacement.
Furnace type and age
High-efficiency condensing furnaces have more components than older 80% units, and parts for discontinued models can be harder to source.
Emergency timing
Overnight, weekend, and holiday no-heat calls during a freeze carry an after-hours premium versus scheduled daytime repair.
Access and installation quality
Furnaces in tight attic or crawlspace locations, or systems with prior improper installation, take more time to service safely.

Frequently Asked Questions
Common questions about furnace repair in Chicago.
No-heat calls are our top priority during Chicago winters. We offer a 60-minute emergency call-back and same-day service whenever weather and staffing allow. If you smell gas or a CO alarm sounds, leave the home and call 911 or your gas utility before calling us.
If you smell gas, hear a delayed 'boom' on ignition, see a yellow flame, or a CO detector alarms, shut the system off and call for service — do not keep running it. These can signal a combustion or heat-exchanger problem that needs professional attention before the furnace is used again.
Repair usually makes sense for isolated failures on furnaces under about 15 years old. Replacement becomes the better value when the heat exchanger is cracked, repairs are recurring, efficiency is low, or the unit is near the end of its life. We give you both options in writing with real numbers.
Yes. We service everything from modern condensing furnaces to the older 80% and gravity-style systems common in vintage Chicago homes and two-flats, as well as boilers and hydronic heat.
