HVAC in Illinois: What Homeowners Should Know
- Climate and system demand: Illinois's climate determines how hard HVAC systems work. In hotter regions, AC units accumulate operating hours quickly, shortening system lifespan and making regular maintenance especially important.
- HVAC licensing requirements: IL requires HVAC contractors to be licensed and carry insurance. Always verify license status before authorizing major repairs or installations — unlicensed work creates liability and may void equipment warranties.
- Energy efficiency incentives: Illinois utility companies and federal programs (Inflation Reduction Act) offer rebates and tax credits for high-efficiency HVAC equipment. Ask your contractor about incentives before finalizing a replacement decision.
- R-22 and aging systems: Older systems using R-22 refrigerant are a common issue in Illinois homes. R-22 is no longer manufactured, making refrigerant refills expensive — any R-22 leak on a system over 12 years old is typically a replacement trigger.
