Before you call
Furnace Not Working? Check These First
A surprising number of no-heat calls come down to something you can check in a couple of minutes. If none of these get the heat back on, call us and tell us what you have already tried.
Check the thermostat
Make sure it is set to Heat, the set temperature is above room temperature, and the batteries are not dead. A blank screen is one of the most common no-heat calls.
Look at the air filter
A badly clogged filter can make the furnace overheat and shut itself off. If it is grey and caked with dust, replace it and give the system a few minutes.
Check the switch and breaker
Furnaces have a light-switch-style power switch on or near the unit, often mistaken for a light. Confirm it is on and that the breaker has not tripped.
Make sure the door panel is closed
A safety switch keeps the furnace from running if the front panel is loose or not seated properly after a filter change.
Clear the outdoor vent pipes
High-efficiency furnaces vent through white PVC pipes on an outside wall. Snow, ice or a bird’s nest can block them and shut the furnace down.
Look for water around the furnace
Water pooling at a high-efficiency furnace usually means a blocked or frozen condensate line. Turn the furnace off and call us.

Signs & common problems
Signs You Need Professional Furnace Repair
Recognizing these signs early can prevent further damage and help your furnace last longer. If you notice any of them, it is time to have a technician take a look.
Insufficient heating
If your home feels colder than usual, or the furnace runs and runs without reaching the set temperature, it is struggling.
Ignition issues
A furnace that refuses to turn on, clicks repeatedly or lights and then shuts off can point to an igniter, flame sensor, gas valve or thermostat problem.
Uneven heating
Big differences between rooms or floors signal a blower, airflow or ductwork issue that needs attention.
Unusual sounds and odors
Banging, squealing, rattling or a burning smell are early signs of a failing part. Catching them early usually means a smaller repair.
Rising utility bills
A sudden jump in gas bills often means the furnace is running inefficiently. Watching your bills can save you from bigger problems later.
Short cycling
Turning on and off every few minutes wears parts out quickly and is often caused by a dirty filter, a dirty flame sensor or overheating.
Common furnace problems and what causes them
| Symptom | Common causes | What our technicians check |
|---|---|---|
| Furnace won’t turn on | Thermostat settings or batteries, power switch or breaker, a tripped safety limit, failed control board | Power, thermostat, safety switches and control board diagnostics |
| Blowing cold air | Ignition failure, dirty flame sensor, overheating from a clogged filter, blocked condensate line, thermostat fan set to On | Ignition sequence, flame sensor, limit switch, condensate drain and venting |
| Turns on and off constantly | Dirty filter, dirty flame sensor, overheating, an oversized furnace, thermostat location | Airflow, temperature rise, flame sensing and thermostat placement |
| Clicking but won’t light | Worn hot surface igniter, gas valve, pressure switch or inducer motor problem | Igniter, gas supply and valve, pressure switch and inducer motor |
| Loud banging, squealing or rattling | Delayed ignition, worn blower motor bearings or belt, loose panels or ductwork | Burners, blower assembly, motor and cabinet hardware |
| Water around the furnace | Blocked or frozen condensate line, failed condensate pump, cracked secondary heat exchanger | Condensate drain, trap, pump and heat exchanger |
Most of these problems are repairable. Common repairs include flame sensor cleaning or replacement, igniter failure, blower motor and capacitor problems, pressure switch faults and control board malfunctions. If your furnace is over 15 years old and failing often, it may be more cost-effective to consider furnace replacement rather than ongoing repairs.
Chicago conditions
Why Chicago Furnaces Break Down More Often
Chicago is hard on heating equipment. Understanding why helps explain the repairs we see most, and how to prevent them.
A long heating season
Chicago furnaces run from fall well into spring, so they rack up far more operating hours each year than furnaces in milder climates.
Deep cold snaps
Polar vortex weeks push furnaces to run almost nonstop. Weak parts that held up in mild weather tend to fail on the coldest nights.
Older homes and ductwork
Bungalows, greystones and two-flats often have older ducts, shared chimneys and tight basements that make furnaces work harder.
Snow-blocked vents
Snowdrifts and ice can block the PVC vents on high-efficiency furnaces, one of the most common winter shutdowns we see.
How it works
Our Comprehensive Furnace Repair Process
A systematic process means the right fix the first time, not a string of guesses.
Initial inspection
A comprehensive assessment of your furnace and heating system to understand the problem and its history.
Diagnostics and a flat-rate price
Advanced testing pinpoints the specific fault. You get a flat, upfront price before any repair begins.
Repair
Efficient repairs using quality parts. Our fully stocked trucks let us finish most repairs on the first visit.
Testing
Rigorous checks make sure the furnace starts, runs and heats properly before we leave.
Not sure if your furnace needs a repair or a full evaluation? We also offer a furnace inspection that covers your entire heating system.
Pricing
Furnace Repair Cost in Chicago
We charge a diagnostic fee to properly identify the problem, and if you go ahead with the repair, that fee is applied toward the cost of the work. You receive a flat-rate price before any repair begins, so there are no surprises on the invoice. What the repair costs depends mostly on which part has failed.
Smaller repairs
Flame sensor cleaning, igniters, capacitors, thermostat issues and filter-related problems are usually the quickest and least expensive fixes.
Mid-range repairs
Inducer motors, pressure switches, gas valves and condensate pumps cost more in parts but are still routine same-day repairs in most cases.
Major repairs
Blower motors, control boards and especially heat exchangers are the most expensive. On an older furnace, this is where replacement often makes more sense.

Repair or replace?
Should You Repair or Replace Your Furnace?
Most furnace problems are worth repairing, especially on a furnace under about 12 years old. A simple guideline is the $5,000 rule: multiply the repair cost by the furnace’s age. If the number exceeds $5,000, replacement may be the better long-term option.
Age, safety and efficiency matter too. Most furnaces last 15 to 20 years, and Chicago’s long heating season can shorten that without annual tune-ups. A cracked heat exchanger, repeated breakdowns or steadily rising gas bills on an older furnace usually point toward replacement. If replacement makes more sense, we provide no-obligation estimates, financing options and seasonal promotions, and we will never push a new furnace when a repair will do.

Prevent breakdowns
Prevent the Next Breakdown With Fall Maintenance
Many of the repairs we make in January could have been caught in October. A yearly furnace tune-up cleans the flame sensor and burners, checks the igniter, blower, safety controls and venting, and tests for carbon monoxide, which is when worn parts show up before they fail.
Between visits, change the filter every one to three months during the heating season and keep the outdoor vent pipes clear of snow. Our maintenance plan schedules the tune-up for you and adds priority service and member savings on repairs.

FAQs
Furnace Repair FAQs
How much does furnace repair cost in Chicago?
Furnace repair in Chicago typically ranges from $150 to $1,200, depending on the issue and parts needed. Browns Heating & Cooling charges a diagnostic fee to properly identify the problem. If you move forward with the repair, that fee is applied toward the cost of the work, and you receive flat-rate pricing before any repair begins.
Should I repair or replace my furnace?
A simple guideline is the $5,000 rule: multiply the repair cost by the furnace’s age. If the number exceeds $5,000, replacement may be the better long-term option. If replacement makes more sense, we provide no-obligation replacement estimates, financing options and seasonal promotions. Learn more about furnace installation and replacement.
What are the most common furnace repairs?
Common repairs include flame sensor replacement, igniter failure, blower motor issues, capacitor problems and control board malfunctions. In Chicago winters, short cycling and no-heat calls are especially frequent. Most repairs can be completed the same day.
What is the most expensive part to replace in a furnace?
The heat exchanger is usually the most expensive component because of the labor and safety requirements involved. Blower motors and control boards can also be costly. When major components fail, we help you decide whether repair or replacement makes better financial sense.
What should I do if my furnace stops working?
First check the thermostat setting and batteries, the air filter, the furnace power switch and breaker, and the outdoor vent pipes for snow. If that doesn’t restore heat, turn the system off and call us at (708) 536-8134. If you smell gas or your carbon monoxide alarm sounds, leave the house first and call your gas utility or 911 from outside.
Why is my furnace blowing cold air?
The most common causes are a dirty flame sensor, a failed igniter, a furnace overheating because of a clogged filter, a blocked condensate line on high-efficiency models, or a thermostat fan set to On instead of Auto. A technician can test each of these and fix the actual cause.
Why does my furnace keep turning on and off?
Short cycling is usually caused by a dirty filter, a dirty flame sensor, overheating, a poorly placed thermostat or a furnace that is too large for the home. It wears out parts quickly and raises bills, so it is worth having checked early.
Can a dirty flame sensor cause my furnace to shut off?
Yes. If the sensor cannot detect a proper flame, the furnace shuts down as a safety measure. Cleaning may help, but a professional inspection ensures safe and reliable operation.
How long does a furnace last in Chicago?
Most furnaces last 15 to 20 years, depending on usage and maintenance. Chicago’s long heating season can shorten that lifespan without annual tune-ups.
Will homeowners insurance cover furnace repair?
Insurance typically does not cover wear and tear. However, damage caused by a covered event, such as a power surge or fire, may qualify. We can provide documentation if needed.
Do you offer financing for furnace repair or replacement?
Financing options are available for larger repairs and full system replacements for qualified customers. Ask about current promotions or available discounts when scheduling service, or see our financing options.
Do you offer 24/7 emergency furnace repair?
Yes. Call (708) 536-8134 any time, day or night. See our emergency HVAC service page for details.
