Rebates are step one
Once you know what Illinois pays, here's the rest of the path: what order to do the work in, and what belongs on a fair quote.

Midea EVOX G³ for Older Multifamily Retrofits: A Chicago Case Study
This is a sponsored case study from Midea about a heat pump product used in an older apartment retrofit in Lansing, Illinois — worth reading with that in mind, since the details come from the manufacturer's own marketing video and interviews. An owner of a six-building, 144-unit complex built in the 1960s needed to replace failing gas furnaces without upgrading electrical panels, opening walls, or tearing out old ductwork. He chose Midea's EVOX G³, a ducted heat pump (a system that heats and cools by moving heat rather than burning fuel) small enough to fit narrow mechanical closets. According to the installer and owner, the units went into the existing footprint, reused the old ductwork, and connected to standard thermostat wiring without new electrical work. Midea's own spec sheet lists cooling and heating efficiency ratings (SEER2 up to 19.0, HSPF2-4 up to 10.8) and says the system keeps full heating output down to -13°F. Residents reported more even heat and less noise afterward. For your own home, the useful takeaway isn't the specific product but the pattern it points to: older buildings with tight mechanical spaces, older wiring, and usable ductwork are not automatically stuck with gas heat. Heat pump options exist that can work within those constraints. But Midea's own material is careful to note that electrical needs, duct compatibility, and eligibility for any tax credits or rebates vary by project and current program rules, so those specifics would need to be checked for your particular house rather than assumed from this one case.
Foss & Company closes $150 million Section 48E tax equity deal for Illinois distributed energy portfolio
A group of investors has put about $150 million into a batch of solar projects in Illinois, run by a partnership between Summit Ridge Energy and Apollo Global Management. The money comes through a financing method called tax equity, where companies like banks and insurance firms fund clean energy projects in exchange for tax credits. This particular deal is one of the first done under a newer federal tax credit rule, called Section 48E, which replaces older solar-specific credits with a broader "technology-neutral" version and adds stricter rules about where equipment can come from, to keep out gear tied to certain foreign entities. For homeowners, the direct effect is limited, but the details show how these projects can lower costs for participants. More than half the portfolio will take part in Illinois' Adjustable Block Program, a state program that locks in 15- to 20-year contracts for renewable energy credits, with some contracts specifically tied to low-income subscribers. The projects also qualify for extra federal credits for using U.S.-made equipment, for being built in areas with a history of energy industry jobs, and for serving lower-income households. This is the eighth such deal between Foss & Company and Summit Ridge Energy, and the companies say it sets a model for structuring future deals under the new federal rules. If you live in Illinois and are weighing community solar subscriptions or watching for local clean energy programs, this signals continued investment in that space, backed by both state contracts and federal tax incentives.
