Furnace Installation & Replacement in Chicago, IL
Energy-efficient furnace replacement sized and installed for Chicago winters — with permits, financing, and honest advice.
A new furnace has to do one thing without fail: keep your family warm and safe through a Chicago winter. Polar Refrigeration & Air Control installs high-efficiency gas furnaces sized to your home, installed to code, and commissioned properly so they deliver every bit of the efficiency you pay for — and last their full expected life.
We start with a heating load calculation, not a guess. An oversized furnace short-cycles, wears out early, and leaves warm and cold spots; an undersized one struggles on the coldest nights. We factor in your home's construction, ductwork, and the region's roughly 5,974 annual heating degree days to recommend the right capacity and efficiency.
You get a written good-better-best proposal comparing AFUE efficiency, staging, warranties, and planning costs — plus financing and any available Illinois rebates. We pull the permit and handle inspection so the job is done right and on the record.
Signs You Need a New Furnace
- The furnace is 15–20+ years old and needs frequent repairs
- A cracked heat exchanger has been diagnosed
- Heating bills keep rising despite maintenance
- The home heats unevenly with persistent cold rooms
- The furnace is noisy, short-cycles, or struggles on cold nights
- A major component (blower, control board, gas valve) has failed
- You want lower bills and a quieter, more consistent system
Choosing the Right Furnace Efficiency
Furnace efficiency is measured by AFUE — the percentage of fuel converted to usable heat. Standard units run around 80% AFUE, while high-efficiency condensing furnaces reach 90–98%, capturing heat that would otherwise escape up the flue. In a cold, long Chicago heating season, that efficiency difference adds up to real savings every winter.
Beyond efficiency, staging matters for comfort. A single-stage furnace runs full-blast or off; a two-stage or modulating furnace runs longer at lower output, keeping temperatures steadier and the air quieter. We help you weigh the upfront cost against the comfort and savings so the choice fits your home and budget.
- High-efficiency condensing gas furnaces (90–98% AFUE)
- Two-stage and modulating models for even comfort
- Matched blowers for reliable AC airflow in summer
- Boiler and hydronic heat replacement options
- Smart thermostat integration
Rebates, Financing & Long-Term Value
High-efficiency heating equipment often qualifies for utility and manufacturer rebates, and federal energy incentives can further offset the cost. We help you identify what applies to your project and offer financing that turns a large one-time expense into manageable monthly payments. The goal is a system that pays you back in comfort and lower bills for years.

What Affects the Cost
The cost of a furnace replacement in Chicago depends on efficiency tier, size, and the condition of your existing venting and ductwork. Here's what actually drives the number.
Efficiency and staging
A high-efficiency, modulating furnace costs more than a basic single-stage 80% unit but returns lower bills and better comfort over its life.
Venting changes
Moving from an 80% to a 90%+ condensing furnace usually requires new PVC venting and a condensate drain, which affects labor.
Ductwork and electrical
Duct sealing, returns, or electrical adjustments may be needed so the new system performs to its rating.
Permits and access
Chicago mechanical permits and difficult equipment locations (attics, tight closets) factor into the total.
