"If your heat is out at 2am, you don't want a sales pitch. You want heat. That's what we do." - Bernie
Chicago Heat Exchanger Repair & Replacement
It's the oldest trick in the book. A tech shows you a rust spot on your heat exchanger and says "This is a crack! It's leaking Carbon Monoxide! I have to shut off your gas unless you buy a new furnace today."
We Replace These Every Week
Warranty Replacement Specialists
Did you know most heat exchangers have a 20-year or lifetime part warranty? If yours is under warranty, we can replace just the part for a fraction of the cost of a new furnace. We've done these for as low as $2,000 (labor only).
We Want to Help, Not Sell
If money is tight, we aren't interested in pressuring you into debt. As a local HVAC Contractor, we will take the time to strip the furnace down and rebuild it if that's what makes sense for your budget. We want to give you heat, not a loan application.
Second Opinions are Free
If another company has condemned your furnace, call us. We'll come out, inspect the crack ourselves, and give you honest options. Sometimes, it's not even a crack - it's just a rust stain.

Built for Chicago's Toughest Conditions
During the 2019 Polar Vortex, Chicago experienced wind chills of -52°F - the coldest in 34 years. Schools closed. Pipes froze. And furnaces across the city failed under the strain. Since that historic event, we've helped hundreds of Chicago homeowners upgrade to high-efficiency furnaces rated for extreme cold, and we've repaired countless blower motors, control boards, and inducer motors that couldn't handle the load.
Whether you live in a classic Chicago bungalow from the 1920s, a two-flat in Avondale, or a Victorian graystone in Lincoln Park, we understand how your home's architecture affects its heating needs. Our technicians are trained to diagnose thermostat issues, gas valve problems, and pilot light failures in any type of Chicago home.
