GSHA Services, LTD replaced an aging central air conditioning system for a homeowner in Itasca, IL with a new Lennox Merit ML14KC1-030 air conditioner (2.5 ton, up to 15 SEER2) and a matched Lennox CK40UT-30B upflow evaporator coil. Our Lennox-certified technicians removed the old condenser, set the new ML14KC1 on a level pad, installed the new coil on top of the existing furnace, brazed and pressure-tested the refrigerant lines with nitrogen, pulled a deep vacuum, and charged the system to Lennox factory specifications before verifying superheat, subcooling, and temperature split. The Lennox Merit series provides quiet, efficient cooling backed by a 10-year parts limited warranty, and the matched coil ensures the system performs at its full rated efficiency through hot DuPage County summers. GSHA Services, LTD is a Lennox dealer providing air conditioning installation, AC replacement, and HVAC repair in Itasca, Roselle, Bloomingdale, Wood Dale, Addison, Medinah, Elk Grove Village, and throughout DuPage County, IL.
