GSHA Services, LTD installed a complete Lennox comfort system for a homeowner in Algonquin, IL. The upgrade included a Lennox Elite EL297V two-stage variable-speed gas furnace (model EL297UH110XV48C, 97% AFUE), a Lennox Elite EL18KCV 4-ton variable-capacity air conditioner with a CK40 cased coil, a Dave Lennox Signature S40 smart thermostat, a Healthy Climate HCC20 media air cleaner, a whole-home power humidifier, and a UV air purifier. Before start-up our crew performed a full Nikro air duct cleaning and dryer vent cleaning so the new system moves clean air from day one. New sheet-metal transitions, PVC venting, condensate piping, and a fresh refrigerant line set completed the job.
