IL's diverse climate demands HVAC setups that go beyond basic functionality. In Johnston City, IL, summer humidity often exceeds 70%, forcing AC units to cycle excessively and leading to rapid evaporator coil corrosion. This not only reduces cooling performance but also spikes energy demands—studies from the U.S. Department of Energy indicate systems in humid IL regions operate up to 25% harder than in drier areas.
