Claim This BusinessGreen Homes Illinois is an East Peoria-based energy efficiency contractor founded by Kevin Johnston and operating throughout the greater Peoria metropolitan area, including Washington and Morton. With a 4.8-star average drawn from 105 client reviews, the firm maintains 24-hour availability across all seven days of the week. The company specializes in whole-home performance assessments rather than isolated equipment replacements, positioning energy audits as the diagnostic starting point for every engagement.
What separates Green Homes Illinois from contractors who simply sell equipment is the structured approach to energy modeling. During audits the team employs specialized diagnostic equipment and software to evaluate insulation, air handling, window performance, and indoor air quality as interconnected systems. Johnston's crew also manages scheduling logistics and paperwork on behalf of homeowners, and actively assists clients in accessing Ameren utility rebates that offset upgrade costs. For qualifying households the firm has completed HUD-funded renovation packages encompassing furnace replacement, central air installation, water heating, attic sealing, and ventilation improvements.
Customer testimonials underscore the consultative style that drives repeat referrals. Lisa Barry reported monthly electric bill reductions ranging from 40 to 120 dollars following insulation and temperature-control corrections, noting that the crew returned calls promptly and honored scheduled appointments. Josh Wieland specifically praised Johnston for explaining each recommendation and declining to propose work that lacked practical justification. Anita Crooks recounted a comprehensive HUD project that replaced her heating and cooling system, water heater, attic insulation, and bathroom ventilation through a single coordinated contract, describing the crews as efficient and professional throughout a multi-stage scope.
Kevin Johnston appears by name in every detailed review, with homeowners consistently characterizing him as communicative and honest rather than promotional. Savings quantified in reviews range from 40 to 120 dollars per month on electric bills following insulation and HVAC upgrades. Multiple clients contrast Green Homes Illinois favorably against contractors who measured, quoted, and departed without explanation.
