Fast Response When Chicago's Cold Bites

We keep extra staff available for emergencies and dispatch across Chicagoland with fully-stocked trucks so most repairs finish in one visit.
Why Chicago Furnaces Work Harder
Chicago experiences heating demands unlike most U.S. cities. Your system faces conditions that force longer run times and stress components more quickly.
Chicago Climate Factors
| Climate Factor | Impact on Your Furnace |
|---|---|
| Lake Effect Weather | Moisture-heavy air creates temperature swings that cycle your system more frequently |
| Polar Vortex Events | Extended operation below -10°F pushes furnaces to maximum capacity for days |
| Urban Heat Island Edges | Rapid temperature differences between downtown and neighborhoods force constant adjustment |
| Aging Housing Stock | Many Chicago homes built 1900-1950 have undersized ductwork that reduces efficiency |

Aging Housing Stock
Since 1970, Chicago winters have warmed by 3.2°F on average, but extreme cold snaps still occur. Your furnace needs to handle both mild stretches and arctic blasts within the same season.

Common Questions Chicago Homeowners Ask
How quickly can you arrive for an emergency?
We typically dispatch within 2 to 3 hours across Chicagoland. During severe weather events, when every company gets slammed, we maintain extra staff specifically for emergencies.
Which furnace brands do you repair?
All major brands: Lennox, Carrier, Trane, Rheem, Goodman, Amana, Bryant, York, Payne, and others. As a Lennox Premier Dealer, we have particularly deep expertise with Lennox systems.
Should I repair or replace my old furnace?
Generally, if your furnace is under 10 years old and repair costs less than 50% of the price of a new system, repair makes sense. For furnaces 15+ years old with expensive repairs, replacement often provides better value long-term.
How do I know if my furnace is dangerous?
Yellow pilot light (should be blue), soot buildup near the unit, excessive rust, cracks in the heat exchanger, or your carbon monoxide detector is alarming. Any of these requires immediate professional attention.
What is your 1-Year No-Breakdown Guarantee?
If your furnace breaks down within one year of our repair, we return to fix the issue at no additional charge for parts or labor related to the original repair.
Why does Chicago’s weather stress furnaces more than other cities?
Lake effect conditions create temperature swings that cycle your system frequently. Arctic air masses push furnaces to maximum capacity for extended periods. The combination of extreme cold snaps and milder stretches forces your system to work harder throughout the season.
