We completed a comprehensive HVAC system upgrade for a residence in Aldie, Virginia. Our team installed a new Trane two-stage variable speed gas furnace along with a high-efficiency central air conditioning unit to provide reliable year-round climate control. This installation focused on maximizing energy efficiency while ensuring consistent heating and cooling throughout the home's various levels. To enhance indoor air quality, we integrated a suite of specialized components including an AprilAire steam humidifier, a whole-home dehumidifier, and an electronic air cleaner. We also implemented an AprilAire zone control system with multiple digital thermostats, allowing for precise temperature and humidity management in separate living areas. The final configuration provides the homeowners with improved air filtration and custom comfort settings via an intuitive touchscreen interface.
