What our furnace replacement includes
Every replacement we do covers the equipment, the labor, the permit, and the startup test. Here is what is in the standard scope, and what we price separately if your home needs it.
New furnace and thermostat
We supply and install a correctly sized Carrier, Trane, Lennox, Rheem, or Goodman furnace, plus a new Honeywell or Ecobee thermostat wired and configured for your system.
Permit and inspection
We pull the City of Chicago mechanical permit and meet the inspector on site. You get the signed inspection card, which matters when you sell the property.
Flue, gas, and electrical
New PVC flue pipe or metal venting, gas piping sized to code, and a dedicated electrical circuit with a service switch. We seal every penetration and test every joint for leaks.
Duct connection and sealing
We connect the new furnace to your existing sheet metal ductwork or flex duct, seal the plenum, and check static pressure so airflow matches the equipment.
Haul-away and disposal
We remove the old furnace, the old flue materials, and any debris, and dispose of it properly. You do not need to rent a dumpster or move anything yourself.
Startup and combustion test
We fire the furnace, run a combustion analyzer and manometer, verify temperature rise and gas pressure, and walk you through the filter, thermostat, and shutoff before we leave.
Homes and businesses.
The approach is the same for a home and a business. What changes is the access, the schedule and who needs the paperwork.
For properties
We replace furnaces in rental flats, small commercial spaces, and multi-unit buildings. Scheduling is coordinated with tenants and building management.
- Multi-unit furnace swaps
- Tenant-occupied scheduling
- Building management coordination
What furnace replacement Chicago IL actually involves
A plain-language look at what Furnace Replacement involves and when it is needed.
See how it worksFurnace replacement Chicago IL is the removal of your existing gas furnace and the installation of a correctly sized, code-compliant unit with new flue, gas, and electrical connections. We start with an ACCA Manual J load calculation so the new equipment matches your home's actual heat loss, not a guess from the old nameplate. Then we set the furnace, seal the plenum, run a combustion analyzer, and verify temperature rise before we call the job done.
Most Chicago homeowners call us when the furnace is blowing cold air, short cycling, or the heat exchanger has cracked after 18 to local experience. In a city where January design temperatures hit 2°F, a failing furnace is not something you can put off. If you are searching for a Chicago furnace install company that handles permits, haul-away, and startup in one visit, we do that work every week across Cook County.
A correctly sized furnace, installed to code, is what keeps a Chicago home warm through February.
- What it is
- Removing an old furnace and installing a new one with new venting, gas, and electrical connections.
- When you need it
- Cracked heat exchanger, repeated breakdowns, rising gas bills, or a furnace past 18 years old.
- What to expect
- One to two days on site, a permit, a startup test, and a walkthrough of your new system.
How our furnace replacement process runs
Five steps, one crew, and a clear timeline. Here is exactly what happens from your first call to the final combustion test.
-
Phone triage
We ask about your furnace age, fuel type, and symptoms, then schedule a visit. If you have no heat, we prioritize you. Most calls get a prompt or next-morning appointment, and we confirm the window by text.
- Phone triage
- Symptoms checked
- Visit scheduled
-
In-home assessment
A technician measures your home, checks existing ductwork, flue routing, and gas line size, and runs an ACCA Manual J load calculation. You get a written scope with equipment options, efficiency ratings, and a firm price before anyone touches a wrench.
- Load calculation
- Ductwork checked
- Written price

Tools and methods we use on every install
Move across a circle, or focus it and press Enter, for an illustrative thermal view of the photograph.
Combustion analyzer
Measures oxygen, carbon monoxide, and flue temperature at startup to confirm the furnace is burning clean and safely.
Manifold gauge set
Checks gas pressure at the valve and verifies the furnace is set to manufacturer spec for your altitude and fuel type.
Manometer
Reads static pressure across the furnace and ductwork so we can set blower speed and catch restricted returns.
Thermal imaging camera
Finds duct leakage, missing insulation, and cold spots in walls before we finalize the install.
Digital multimeter
Tests voltage, continuity, and amp draw on the control board, blower motor, and igniter during startup.
Thermal views are illustrative, generated from the photographs.
Methods
Vacuum pump and recovery machine
Used when we pair a new furnace with AC work, pulling a proper vacuum and recovering R-410A or R-32 refrigerant.
Sheet metal tools and tube bender
Fabricate plenum transitions, seal duct connections, and bend copper line sets cleanly when we add AC.
ACCA Manual J Load Calculation
We measure windows, insulation, and square footage room by room to calculate actual heat loss. This is how we size the furnace correctly instead of copying the old nameplate.
ACCA Manual D Duct Design
We check duct sizing and static pressure against the new furnace's airflow requirements. If the return is undersized, we tell you before install day, not after.
ICC Mechanical Code Compliance
Every install follows the International Mechanical Code as adopted by Chicago, covering clearances, venting, gas piping, and combustion air.
AHRI Certified Equipment matching
We pair furnaces with coils and condensers listed in the AHRI directory so the system performs at its rated efficiency and qualifies for rebates.
When Chicago homeowners replace their furnace
prompt bungalow
A 20-year-old furnace in a Norwood Park bungalow fails during a January cold snap.
We stock common furnace sizes on the truck and can complete a prompt furnace replacement Norwood Park Chicago job when the equipment matches. If not, we set temporary heat and install the next morning.
Outcome: Heat restored within 24 hours, new 96% AFUE furnace installed, permit pulled, and the old unit hauled away.
Two-flat pair
A Logan Square two-flat owner wants to replace both furnaces before winter and lower tenant gas bills.
We run Manual J calculations on both units, recommend two-stage furnaces, and schedule both installs across three days so tenants keep heat overnight.
Outcome: Two new furnaces, sealed ductwork, and roughly 30% lower gas usage across both units.
Condo replacement
A Lakeview condo owner is told the heat exchanger is cracked and needs a replacement fast.
We verify the crack with a combustion analyzer, shut the unit down for safety, and install a new furnace with a new PVC flue and condensate pump within two days.
Furnace plus AC
A homeowner in Sauganash wants to replace an old gas furnace and add central AC at the same time.
We pair a new furnace with a matched AC condenser and evaporator coil, running new copper line sets and a condensate drain line in one visit.
Greystone retrofit
A Wicker Park greystone owner needs to replace an old gas furnace without tearing up the building.
We route the new PVC flue through an existing chase, use flex duct where the old ductwork is inaccessible, and protect the original floors and trim during the install.
Outcome: New high-efficiency heat with no structural changes and the greystone's original details intact.
How furnace replacement runs in Chicago
Chicago winters are hard on heating equipment. Design temperatures drop to 2°F, and furnaces run near-continuously from December through February. That load is why we size every replacement with a Manual J calculation rather than square footage, and why we insist on a combustion analyzer at startup. Building stock matters too.
Greystones and two-flats often have original ductwork that is undersized for modern equipment, so we check static pressure and seal what we can reach. In high-rises, we coordinate with building management on flue routing and elevator use. The City of Chicago requires a mechanical permit for furnace replacement, and we pull it and meet the inspector on site.
If you need a high efficiency furnace installation Chicago Illinois homeowners can count on, we handle the whole scope, including the PVC flue and condensate line. We also serve ZIP codes 60018, 60641, 60640, 60643, 60642, and 60649 across Cook County.
- Norwood Park: Mostly single-family bungalows and ranches with basements. We route flues through existing chases and often find undersized return ducts that need attention.
- Logan Square: Dense two-flats and three-flats with shared mechanical spaces. We schedule installs around tenants and keep heat on the other units overnight.
- Lakeview: Mix of greystones and high-rise condos. In high-rises we coordinate flue and condensate routing with building management before install day.
- Sauganash: Larger homes with finished basements and zoned systems. We often pair furnace replacement with AC replacement and new zone controls.
- Wicker Park: Historic greystones with original trim and floors. We protect finishes and use flex duct where the old ductwork cannot be opened up.
- Sustained sub-zero cold snaps in January and February: Furnaces run continuously, exposing weak blower motors and cracked heat exchangers. We prioritize no-heat calls and carry common parts on the truck.

From problem to finished result.
Norwood Park bungalow, no heat in January
Before: A 21-year-old 80% AFUE furnace failed on a Friday night with a cracked heat exchanger. The homeowner had no heat and the forecast was 8°F for the weekend.
After: We installed a 96% AFUE two-stage furnace the next morning, ran a new PVC flue, and verified temperature rise. Gas usage dropped about 30% the following winter.
Change the 16x25x1 filter every 60 to 90 days and schedule a fall tune-up to keep the heat exchanger and igniter in good shape.
Logan Square two-flat, both furnaces replaced
Before: Two original furnaces from the early 2000s were short cycling and leaving the second-floor unit cold. Gas bills had climbed every year for three winters.
After: We replaced both units with correctly sized two-stage furnaces, sealed accessible ductwork, and balanced the registers. Both units now heat evenly and gas use fell roughly 30%.
Keep returns clear, replace filters monthly during heating season, and have both systems tuned each October.
Lakeview condo, cracked heat exchanger
Before: A home inspection flagged a cracked heat exchanger on a 19-year-old furnace. The condo owner needed a safe replacement before closing in three weeks.
After: We installed a new 96% AFUE furnace with a new flue and condensate pump in two days.
Run the furnace monthly in the off-season, keep the condensate line clear, and book a combustion check every fall.
Problems a new furnace solves for Chicago homes
Most replacements start with one of these four problems. If you recognize yours, call us before the next cold front.
- Blowing cold airFurnace blowing cold air in JanuaryA failed hot surface igniter or gas valve leaves you with no heat, and pipes can freeze within hours when the temperature drops below 20°F. We diagnose the failure on site. If the repair is worth doing, we fix it. If the furnace is past 18 years, we price a replacement and can often install quickly.
- Short cyclingFurnace short cycling every few minutesShort cycling strains the heat exchanger, wastes gas, and usually means the furnace is oversized or the ductwork is restricted. We measure static pressure and temperature rise, then run a Manual J calculation. If the equipment is wrong-sized, we replace it with a unit matched to your home and adjust blower speed.
- Cracked heat exchangerCracked heat exchangerA cracked heat exchanger can leak carbon monoxide into your home. It is not a repair most homeowners should put off. We confirm the crack with a combustion analyzer and visual inspection, then shut the unit down. Replacement is the safe path, and we prioritize these calls for prompt or next-day install.
- High gas billsRising gas bills with uneven heatAn 80% AFUE furnace with duct leakage can waste a third of the heat you pay for, and upstairs rooms stay cold all winter. We replace the furnace with a 96% AFUE unit, seal accessible ductwork, and balance the system so every room heats evenly. Most customers see a 25% to 35% drop in gas use.
Why Chicago homeowners replace instead of patch
Reliable heat, lower gas bills, and a system that passes inspection.
Lower gas bills
A high efficiency furnace replacement Chicago, Illinois homeowners choose at 96% AFUE cuts gas use by 25% to 35% compared to an older 80% unit. On a typical Chicago heating season, that is real money back in your pocket every month.
Heat that reaches every room
Uneven heating usually means duct leakage or an oversized furnace short cycling. We seal accessible ductwork, set blower speed to match your static pressure, and balance registers so bedrooms in your greystone stay as warm as the living room.
No more 2 a.m. breakdowns
A cracked heat exchanger or failed inducer motor does not warn you before it quits. New equipment with a fresh hot surface igniter, flame sensor, and control board means you stop gambling on whether heat shows up during a February cold snap.

Furnace replacement questions Chicago homeowners ask
A basic 80% AFUE unit sits at the low end. A 96% AFUE two-stage or modulating furnace with new PVC flue pipe lands higher. That price includes equipment, labor, permit, haul-away, thermostat, and startup.
A standard new furnace installation in Chicago, Illinois takes one to two days. Day one covers removal, setting the new unit, and flue work. Day two handles gas piping, electrical, thermostat, and duct connections. If we are also replacing the AC coil or running new ductwork, plan on three days. We give you a firm timeline before we start.
Size comes from an ACCA Manual J load calculation, not square footage alone. A 1,200-square-foot Chicago bungalow with average insulation often needs 60,000 to 70,000 BTU. A 2,400-square-foot greystone with poor windows may need 100,000 BTU or more. We measure insulation, windows, and ductwork before recommending a size.
Yes. We offer furnace replacement financing Chicago IL homeowners can use to spread the cost over 12 to 60 months, with approved credit. We walk you through the options during the estimate so you can compare monthly payments against the efficiency savings. Ask about it when we are on site, and we will run the numbers with you.
Other heating and cooling work we handle
