See #TheDubsonDifference in action! Dubson Heating, Air Conditioning & Refrigeration recently replaced this early 90s furnace with a Trane S9V2. This two-stage, variable speed furnace maximizes home efficiency during the heating season. With an AFUE of 96%, the S9V2 uses less gas to heat your home versus less efficient models. In addition to a new furnace, we also installed a Trane air conditioner, a 5” filter, a whole-house humidifier and a Nest Thermostat. The customer is pleased with the new heating and cooling system, saying he “looks forward to temperature consistency and reliable home comfort for their family!” To explore your HVAC options, including special incentives for Ameren Illinois customers, call 217.762.8151 today.
