Zoned Hybrid Heating and Cooling Brings Room-by-Room Comfort to a Chestnut Hill Home
PROBLEM: An older Chestnut Hill home had a 5–10°F temperature difference between the first and second floors. Cooling the upstairs at night meant making the first floor uncomfortably cold, and the home's approximately 80% efficient furnace no longer aligned with his comfort or energy-efficiency goals.
SOLUTION: A two-zone hybrid heating and cooling system paired a fully modulating Ruud RD18 heat pump with a 96% efficient, two-stage variable-speed Ruud furnace. New ductwork and independent controls for each floor gave the home more precise comfort, improved humidity control, quieter operation, and less reliance on fossil-fuel heating.
