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.

Smell gas or hear your carbon monoxide alarm? Don’t troubleshoot. Leave the house right away, then call your gas utility’s emergency line or 911 from outside. Once everyone is safe, call us to inspect and repair the furnace.

24/7 emergency service

24/7 Emergency Furnace Repair in Chicago

When your furnace fails, time matters. In a Chicago cold snap, a house without heat can drop toward freezing overnight, and that puts water pipes at risk as well as your family’s comfort. Our 24/7 emergency furnace repair service is built for exactly that moment.

Call any time, day or night, and our team responds quickly to restore your heat. We focus on fixing the immediate problem efficiently and safely, and our fully stocked trucks mean most repairs are finished on the first visit, so your home is warm again without delay.

Call us right away if

  • No heat while temperatures are near or below freezing
  • A burning or electrical smell from the furnace
  • Water leaking from the furnace or around it
  • The furnace keeps shutting off and won’t stay running
  • Elderly family members, infants or pets at home with no heat

Usually fine to schedule

  • One room is cooler than the rest
  • New noises, but the house is still heating
  • Heating bills creeping up over the season
  • It is time for the yearly tune-up or a filter change

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

SymptomCommon causesWhat our technicians check
Furnace won’t turn onThermostat settings or batteries, power switch or breaker, a tripped safety limit, failed control boardPower, thermostat, safety switches and control board diagnostics
Blowing cold airIgnition failure, dirty flame sensor, overheating from a clogged filter, blocked condensate line, thermostat fan set to OnIgnition sequence, flame sensor, limit switch, condensate drain and venting

Loud banging, squealing or rattlingDelayed ignition, worn blower motor bearings or belt, loose panels or ductworkBurners, blower assembly, motor and cabinet hardware
Water around the furnaceBlocked or frozen condensate line, failed condensate pump, cracked secondary heat exchangerCondensate 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.

1

Initial inspection

A comprehensive assessment of your furnace and heating system to understand the problem and its history.

2

Diagnostics and a flat-rate price

Advanced testing pinpoints the specific fault. You get a flat, upfront price before any repair begins.

3

Repair

Efficient repairs using quality parts. Our fully stocked trucks let us finish most repairs on the first visit.

4

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.

Reviews

A Reputation Built on Trust and Quality

★★★★★ Rated 4.9 on Google by Chicago homeowners · See all reviews

I called Browns late Tuesday during a heatwave, and they were able to schedule a service appointment for the next day. The service call cost $125, but that amount goes towards any repair cost if needed so the initial call is essentially free if you need service costing more than $125. The techs arrived exactly on time at the start of the appointment window, and quickly found the issues (dirty condenser coils, refrigerant top-off, and system sealant to address the small leak). Ramond clearly explained the impact of each along with the cost to fix, then confirmed which services I wanted and what my total would be before starting the work. I also appreciate that Ramond answered all my dumb questions about how air conditioning actually works; he's a great science teacher 🤓. The cost was less than I expected for a next-day service (coil cleaning $239, sealant $285, and a few pounds of refrigeratant was $370). During the payment process, the tech didn't prompt for a tip, unlike most companies. So don't forget to ask them for their Zelle/Venmo if you want to send a tip
Quick responses from a professional company. Although it was peak season for AC’s, they were able to send a crew over within 24-hours. This was so critical for us with 3 young kids in the house and the temps rising to 85 degrees. Angelique on the phone gave clear instructions on what I needed to do before the service guys showed up. Ramod & Eric were courteous and wore shoe covers as they entered the house. They took a quick look and knew what needed to be done immediately. As a Realtor, I’ve changed many an AC units and their prices were very fair. We ended up repairing instead of a new AC unit. The repair was less than what he originally quoted. How is that for honest service?! Amazing! They will have to come back for a service ($99) as we ran out of time. I can highly recommend Browns Heating & Cooling without any hesitation.

Highly recommend these guys. We had a cooling issue, and Steven was here and gone in under an hour. He pointed out the issue and repaired it without talking much.

Highly recommend them! We needed a whole house humidifier because the winter air was making everyone in the house feel sick. The installation was very clean, and they tied it right into the water line without any leaks or issues. The technician showed me how to adjust the humidity level based on the temperature outside, so we don't get condensation on the windows. It's made the house feel much more comfortable, and my skin isn't nearly as dry as it used to be. I’m happy with the service.

I decided to upgrade to a Nest thermostat and scheduled the installation with this company. The technician arrived on time and installed the thermostat quickly. He also walked me through the settings and showed me how to control it through the phone app. The system now adjusts the temperature automatically during the day, which is convenient. It has made managing the indoor temperature much easier. The team from Brown’s handled the installation smoothly and made sure everything was working before leaving.

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.
