3 Advantages of a Ductless HVAC System
Is a ductless HVAC system a viable alternative for heating and cooling individual rooms in your home? Every day, ductless heating and cooling units are gaining market share in this country as more people decide that the answer is “Yes.” The system consists of a compact, low-profile indoor air handler incorporating a coil and blower fan mounted on the wall or ceiling of the room. This unit connects via a narrow refrigerant conduit to a downsized outdoor heat pump behind or next to the house, about the size of a large suitcase. In winter, like any heat pump, the system extracts latent heat from outside air, concentrates it with a compressor, then conveys it indoors to the air handler where the coil and blower disperse heat into the room. In summer, the system reverses and cools the room by extracting indoor heat and conveying it outside to be released in outdoor air. A single outdoor heat pump unit can link to up to five ductless air handlers in separate rooms. Ductless HVAC provides three advantages.
- In homes without ductwork for central heating and cooling—or where extending existing ductwork to additional rooms isn’t financially feasible—a ductless system permits low-cost, highly effective heating and cooling of individual rooms without relying on outmoded space heaters and clunky window air conditioners.
- Leaky, inefficient ductwork loses at least 25% of heating or cooling in most homes. Because a ductless system delivers heating and cooling without ducts, operation is more energy-efficient at lower cost. Ductless comfort control is also more accurate as each room has its own dedicated thermostat to individualize temperature to that space.
- Installation of ductless HVAC is far less intensive and disruptive than installing ducts and vents that require major construction. All that’s required are a three-inch hole in an exterior wall to route the refrigerant conduit outdoors, plus mounting the indoor air handler on a wall or ceiling. A two-person team can easily install a ductless system in a single room in one day.
