What We See in Gurnee Homes
Most of Gurnee’s homes were built from the 1980s through the 2000s, so we replace a lot of original builder-grade furnaces and ACs here. A few things come up often:
- Hot upstairs, cold basement. Two-story homes often fight uneven temperatures. Sometimes the fix is balancing or zoning, not a bigger system. See our air balancing service.
- Two systems in larger homes. Larger homes often have separate systems for each floor. We’ll tell you honestly whether both need replacing or just one.
- Oversized original equipment. Builders often installed bigger units than needed. Right-sizing on replacement improves comfort and lowers bills.

Replacement Costs in Gurnee
Every house is different, but here are honest ranges: AC about $4,000–$8,000; heat pump about $6,000–$10,000 before rebates; furnace about $4,000–$10,000 depending on size, efficiency, brand and location. We install Trane, Carrier, Bosch, Midea, LG, Gree and Goodman, and all equipment comes with a 10-year factory parts warranty, with extended labor coverage included or available depending on the package. In our climate, paying extra for anything above about 17 SEER2 rarely pays back.
Rebates and Utilities in Gurnee
Gurnee homes get electricity from ComEd and natural gas from North Shore Gas. ComEd offers instant discounts on qualifying heat pumps, which is why heat pumps have become a realistic option here. See our heat pump page for current ComEd discount details. The federal 25C tax credit for heat pumps and furnaces ended for equipment installed after December 31, 2025, so if someone is still quoting it to you, ask questions.
Maintenance
Our one-time tune-up is $150 and includes a real cleaning of your equipment. An inspection is $79. Maintenance plans start at $15/month and cover an AC visit before cooling season and a furnace visit before heating season.
