What Our Heating & Furnace Service Includes

Furnace Repair

When your furnace is blowing cold air, short-cycling, or not running at all, you need a diagnosis you can trust, not a sales pitch. Our technicians start with a full system diagnostic, checking the ignitor, flame sensor, gas valve, blower motor, and heat exchanger for cracks or failure points. We explain what we find in plain language, quote the repair upfront, and fix it if you give us the go-ahead. Most furnace repairs in Chicago run $150-$700 depending on the part and labor involved, and we carry the components to complete most jobs same-day.

Furnace Replacement

There comes a point when repairing an old furnace costs more than it is worth, especially for units over 15 years old with cracked heat exchangers or failed compressors. We give straight talk about repair versus replace, measuring the cost of the fix against the remaining life of the system and your expected energy bills. Our replacement quotes include removal of the old unit, proper disposal, new equipment installation to Chicago code, and a full test and balance before we leave. We install Carrier, Trane, Lennox, and other major brands, and every installation is backed by our 90-Day Done Right Promise.

Furnace Tune-Up

A seasonal tune-up catches problems before they become 2 a.m. emergencies. Our $89 Seasonal Tune-Up includes a 21-point inspection, combustion analysis, filter check, blower cleaning, and safety test of the heat exchanger and gas connections. In Chicago, where furnaces run hard from November through March, Heating & Furnace - Chicago annual maintenance extends equipment life, keeps efficiency up, and protects your warranty. We recommend scheduling in early fall before the first cold snap hits the Loop and the South Side.

Heat Exchanger Inspection and Replacement

A cracked heat exchanger is a serious safety issue. It can allow carbon monoxide to enter your home, and it is not repairable. Our technicians use visual inspection, combustion analysis, and camera borescopes to check for cracks, corrosion, or metal fatigue. If we find a failure, we show you the evidence, explain your options, and replace the heat exchanger or recommend furnace replacement if the unit is near end of life. We do not use scare tactics. We show you what we see and let you decide.

Ignitor Replacement

Modern furnaces use hot surface ignitors instead of standing pilot lights, and these ceramic components fail after 3-5 years of Chicago heating seasons. A failed ignitor means the furnace will not fire at all, and you will hear the blower running with no heat. We stock ignitors for Carrier, Trane, Lennox, Goodman, and other major brands, and most replacements take under an hour. The part is warrantied, and our work is covered by the 90-Day Done Right Promise.

Gas Valve Repair

The gas valve controls fuel flow to your burners, and when it sticks, leaks, or fails to open, your furnace cannot produce heat or becomes unsafe to operate. Gas valve work requires a trained professional. Our technicians test gas pressure, check for leaks with electronic detectors, and replace the valve with an OEM-spec component if needed. We also verify proper operation of the safety shutoff systems that protect your home. This is not a do-it-yourself repair. Working on gas lines without proper training and tools risks fire, explosion, or carbon monoxide poisoning.

Brands We Service for Heating & Furnace

We have serviced hundreds of Carrier furnaces across Chicago, from the high-efficiency Infinity series to the workhorse Performance line. We stock common Carrier ignitors, flame sensors, and control boards, and our technicians are trained on their variable-speed blower systems and two-stage gas valves. Trane builds some of the most durable furnaces on the market, and we have worked on their XV and XT series units in homes from Bridgeport to the Near South Side. We carry Trane OEM parts and understand their proprietary communicating systems.

Lennox equipment requires specific expertise with their variable-capacity modulating furnaces and their EL296V and SLP98V platforms. We have diagnosed and repaired hundreds of Lennox units in Chicago’s older housing stock, where ductwork sizing and airflow must be matched carefully to the equipment. Goodman furnaces are common in Chicago’s post-war bungalows and two-flats, and we stock the ignitors, gas valves, and control boards that fail most often on these units. Whether you have Carrier, Trane, Lennox, Goodman, or any other make, we can help. Our trucks carry parts for Rheem, York, Daikin, Bryant, and American Standard as well, and we service all nine major residential brands.

Signs You Need Heating & Furnace Right Now

• No heat or insufficient heat. If your thermostat is set to 70 and the house will not get past 62, something is wrong. It could be a failed ignitor, a dirty flame sensor, a failing gas valve, or a cracked heat exchanger. Running the system in this condition strains other components and can turn a simple repair into a major one.
• Strange smells from vents. A brief dust smell when you first turn on the heat is normal in Chicago after months of disuse. But a persistent burning smell, a metallic odor, or the rotten-egg scent of natural gas means you need a professional immediately. Turn the system off and call us.
• Loud banging, rattling, or screeching. Furnaces should run with a steady low hum. Banging can mean delayed ignition, which damages the heat exchanger. Screeching usually signals a failing blower motor bearing. Rattling may be a loose panel or a cracked heat exchanger expanding under heat. None of these sounds should be ignored.
• Short-cycling. If your furnace turns on and off every few minutes, it is not completing a full heating cycle. This wears out components, wastes fuel, and leaves you cold. Causes include a dirty filter, a failing flame sensor, an oversized unit, or a thermostat problem. We diagnose the root cause, not just the symptom.
• Yellow or flickering burner flame. A healthy gas furnace burns with a steady blue flame. Yellow, orange, or flickering flames indicate incomplete combustion, which produces carbon monoxide and wastes fuel. This is a safety issue that requires immediate professional attention. Do not attempt to adjust the burners yourself.

Our Heating & Furnace Process - Step by Step

1. 1
   Call and schedule. When you call (833) 983-1671, a live person answers, 24 hours a day, 7 days a week. We do not put you through a voicemail tree or make you wait for a callback. We ask what is happening with your system, when it started, and what you have noticed. We schedule at a time that works for you, and we will be there when we say.
2. 2
   Arrival and diagnosis. Our technician arrives in a marked truck, in uniform, with shoe covers. We listen to what you have observed, then run a complete diagnostic using digital multimeters, combustion analyzers, manometers for gas pressure, and borescope cameras for heat exchanger inspection. We find the actual problem, not the most expensive guess.
3. 3
   Upfront pricing and explanation. Before any work begins, we explain what we found, show you the evidence if you want to see it, and give you a written price. The price quoted is the price paid. If you choose not to proceed, you pay only the diagnostic fee. No pressure, no surprises.
4. 4
   Repair or replacement with quality parts. We use OEM or equivalent parts, not generic substitutes that fail in a season. Our trucks are stocked so most jobs are completed in one visit. For replacements, we size the equipment properly for your home and Chicago’s climate, not just swap in what was there before.
5. 5
   Testing, cleanup, and written guarantee. We test every system thoroughly before we leave, check airflow at registers, verify thermostat operation, and clean up our work area. You get a written invoice and our 90-Day Done Right Promise. If something is not right, we make it right.
