Full System Replacement in Kenilworth, Illinois
Full System Replacement in Kenilworth typically costs $9,000-$18,000 installed in 2026, depending on home size and efficiency tier.
Where a Kenilworth home has forced-air heating and retrofit cooling, replacing both as a matched system is often the most sensible course - it resolves the compromises of two separate retrofits at once. In these historic homes, a full-system project is careful, engineered work that respects original finishes while modernizing comfort end to end.

Full System Replacement for Kenilworth homes
The forced-air Kenilworth homes we work in usually gained their heating and cooling as separate retrofits, leaving mismatched equipment and distribution that never quite balanced. A full-system replacement lets us engineer the furnace, coil, and condenser together to the home's real load, and decide honestly where conventional ducts work and where a ductless zone would serve a hard-to-reach room better than forcing the system to overreach.
Because these are landmark homes, the install is planned around preservation: discreet condenser placement, venting routed out of sight, and careful protection of plaster and millwork throughout. The installers complete the matched changeout in a coordinated visit, verify every connection. A matched high-efficiency system is also the best candidate for stacked utility incentives, so we size to the thresholds and manage the Nicor and ComEd rebate paperwork on your behalf, with current amounts confirmed in your estimate.
