Signs You Need Boiler Replacement
We never push a new boiler when a repair will do. But when a boiler is unsafe, failing or burning money, replacement is often the smarter long-term investment. These are the signs we look for when Chicago homeowners ask if it is time.
Your boiler is decades old
Many boilers last 15 to 30 years. Older, low-efficiency units waste a large share of every gas dollar on Chicago winter bills.
Repairs every winter
When boiler repair calls are becoming a seasonal habit, that money usually works harder toward a new system.
Leaking heat exchanger
A cracked or corroded heat exchanger usually cannot be repaired cost-effectively and is a clear sign to replace.
Gas bills keep rising
Scale buildup and aging burners reduce efficiency every year. A modern boiler can heat the same home with noticeably less fuel.
Uneven heat between rooms
Cold rooms, slow warm-up and constant radiator bleeding can mean a boiler that no longer matches your home.
Loud kettling or banging
Persistent noise from scale-clogged heat exchangers is a warning sign of an aging, overworked boiler.
Types of Boilers We Install in Chicago
The right boiler depends on your home, your existing radiators or baseboard, and whether you also want it to supply hot water. We explain each option plainly so you can choose without pressure.
Gas hot water (hydronic) boilers
The most common choice for Chicago homes with radiators or baseboard. High-efficiency condensing models turn more of their gas into heat, while standard models are a simpler swap when venting changes would be costly.
Combi boilers
A combination boiler provides home heating and on-demand hot water from one wall-hung unit. It frees up basement space and can replace a separate water heater in smaller homes and condos.
Steam boilers
Many older Chicago buildings were designed around steam. We install replacement steam boilers matched to the existing piping and radiators so the system heats evenly and quietly.
Electric boilers
Electric boilers need no gas line or flue, which makes them a practical option for some condos, additions and homes without gas service.
Replacing a boiler that shares a chimney with your water heater? Ask us about venting. Some Chicago homes may need a chimney liner, or a water heater update, when the boiler changes.
How Our Boiler Installation Works
A boiler is only as good as its installation. Proper planning and system design prevent the common problems caused by improper sizing or shortcuts. Here is exactly what to expect.
- 1Home and system evaluation
We assess your home size, insulation, heat demand, existing piping and radiator or baseboard layout to size the new boiler correctly.
- 2Clear options and quote
You get a written quote with recommended boilers and efficiency choices, plus any piping or venting work needed. No pressure.
- 3Remove the old boiler
We drain the system and safely disconnect and remove your old equipment from the basement or mechanical room.
- 4Install and connect
We set the new boiler and complete piping, venting, gas and electrical connections to Chicago building codes and manufacturer specs.
- 5Fill, purge and pressure test
We refill the system, purge air from every radiator and loop, and pressure test all connections.
- 6Startup, safety checks and walkthrough
We fire the boiler, test safety controls, calibrate the thermostat and show you how to run your new system.
What to Know Before Replacing a Boiler in Chicago
Boiler replacement in Chicago is rarely a simple swap. Two-flats in Lincoln Park, greystones in Bronzeville and bungalows on the South Side all come with their own piping, venting and space challenges.
We plan around them up front so there are no surprises on installation day. Many homeowners pair a new boiler with a smart thermostat for better control, and every new system should get yearly boiler maintenance to protect the investment.

Chicago Boiler Installation FAQs
Answers to the questions Chicago homeowners ask most before replacing a boiler.
Who installs new boilers in Chicago?
Tabor’s Complete Comfort Mechanical (TCC Mechanical) installs and replaces residential boilers across Chicago, including gas hot water, combi, steam and electric boilers. The locally owned, family-operated company uses EPA and NATE-certified technicians and has installed boilers in Chicago since 2005. Call (773) 715-3860.
How long does a boiler installation take?
A straightforward boiler replacement is often completed in one to two days. Jobs that need new venting, piping changes or a switch to a combi or condensing boiler can take longer. We give you a clear schedule with your quote.
Do you remove the old boiler?
Yes. Removal of the old equipment is part of every boiler replacement. We drain the system, disconnect and remove the old boiler, then install and test the new one.
Can I keep my existing radiators?
Usually, yes. Cast iron radiators and baseboard can typically be reused with a new boiler. We check them during the evaluation and size the new boiler to match.
What size boiler do I need?
Boiler size depends on your home’s heat loss, insulation, windows and the radiators or baseboard it feeds. We size every new boiler from an evaluation of your home rather than matching the old unit’s label.
Is a condensing boiler worth it in Chicago?
Often, yes. Chicago’s long heating season means a condensing boiler’s fuel savings add up faster than in milder climates. A standard boiler can still make sense when venting changes would be costly or the existing system is not well suited.
What is a combi boiler and is it right for me?
A combi boiler heats your home and provides on-demand hot water from one compact unit. It is a good fit for condos and smaller homes, but larger homes with high hot water demand may be better served by a boiler plus a separate water heater.
Do I need a permit to replace a boiler in Chicago?
In most cases, yes. Boiler replacements in the City of Chicago generally require a permit and must meet the city’s mechanical code. We will discuss permit requirements when we prepare your quote.
How much does a new boiler cost in Chicago?
It depends on boiler type, size, efficiency, venting and any piping changes. We evaluate your home and provide an upfront quote before any work begins.
Do you install boilers in my neighborhood?
Yes. We install boilers across Chicago, including Lincoln Park, Lakeview, Wicker Park, Bucktown, Hyde Park, Bronzeville, Pilsen, the South Loop, Beverly and Morgan Park, plus Oak Lawn, Orland Park and Tinley Park.
