What We See in Naperville Homes
Naperville has a historic core and many subdivisions built from the 1980s through the 2000s. The city runs its own electric utility, so ComEd heat pump discounts don’t apply. A few things come up often:
- Oversized original equipment. Builders often installed bigger units than needed. Right-sizing on replacement improves comfort and lowers bills.
- Builder-grade equipment at the end of its life. Many homes here still have the original furnace and AC from when the house was built. At 20+ years, replacement usually beats repeated repairs.
- 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.

Replacement Costs in Naperville
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 Naperville
Naperville runs its own municipal electric utility, so ComEd’s heat pump discounts don’t apply here. Ask us about current Naperville utility programs before you buy. Gas service is through Nicor Gas. 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.
