What Chicago Homeowners Should Know About AC Installation
How a Central Air Conditioner Works
A central AC system uses refrigerant to absorb heat from indoor air at the evaporator coil (inside your air handler or furnace), then releases that heat outside at the condenser coil. The refrigerant cycle repeats continuously, cooling and dehumidifying your home. Modern systems use R-454B or R-410A refrigerant and achieve 16–26 SEER2 efficiency ratings.
Understanding SEER2 Ratings
SEER2 (Seasonal Energy Efficiency Ratio 2) measures cooling output per unit of energy consumed. The federal minimum for Illinois is 14.3 SEER2. A 16 SEER2 unit uses roughly 10% less energy than a 14.3 SEER2 unit. High-efficiency variable-speed systems at 20+ SEER2 can cut cooling costs by 30–40% compared to older 10 SEER equipment.
Matched System Importance
An air conditioner condenser must be matched to the correct indoor coil (evaporator) and air handler or furnace. Mismatched components reduce efficiency, void manufacturer warranties, and can cause premature compressor failure. D's Air always installs matched, certified system combinations.
Cooling Design for Chicago Homes
Chicago's humid summers demand proper equipment sizing and refrigerant charge. An oversized AC cools quickly but short-cycles, leaving humidity high and comfort low. An undersized unit runs constantly and can't maintain setpoint on the hottest days. D's Air performs Manual J load calculations on every installation.
