GSHA Services, LTD replaced both central air conditioning systems for a homeowner in Des Plaines, IL. We installed two Carrier Comfort 14 air conditioners, a 3-ton 26SCA436 and a 3.5-ton 26SCA442, each matched with a new Carrier uncased evaporator coil (CAAVU3617 and CAAVU4221) fitted to the existing furnaces. Each condenser was set on a new composite pad with a fresh refrigerant line set, a new electrical whip and disconnect, and the systems were evacuated, charged to factory subcooling, and tested for proper temperature split. Two right-sized systems mean each floor of the home cools evenly without short cycling.
