GSHA Services, LTD replaced two complete HVAC systems for a homeowner in Mundelein, IL. The project included two Lennox Elite EL297V two-stage variable-speed gas furnaces (97% AFUE, models EL297UH070XV36B and EL297UH090XV60C), a Lennox Elite EL16KC1 3.5-ton air conditioner with matching CK40 cased coils, a Dave Lennox Signature S40 smart thermostat, an iHarmony zoning system with damper control module and zone sensors so every floor is comfortable, a Healthy Climate media air cleaner, a whole-home humidifier, and a UV air purifier. Our crew fabricated new plenums and transitions, ran new venting and condensate lines, set both outdoor units on new pads, and commissioned and balanced the zoned system.
