Ductless Heating and Cooling System Benefits

December 29, 2014

Keith Air Conditioning, Inc. and HeatingIf you’re planning to renovate an attic or porch, or create a new addition to your home, consider using a ductless heating and cooling system for maximum comfort and energy efficiency. These systems, also called mini-splits, are heat pumps that don’t require any ductwork to distribute the conditioned air. Heat pumps are ideal HVAC appliances in this mild winter climate.

Like HVAC systems, a ductless heating and cooling system uses an outdoor condenser and an indoor air handler. A narrow conduit connects the two and delivers the power, refrigerant and the drain line. The condenser can either rest on a pad outside or hang from the exterior wall. The conduit comes in a variety of lengths. The air handlers can hang on the wall, from the ceiling, or sit on the floor.

Energy Efficiency

Ductless air handlers deliver the air directly into the room, so there are no air or thermal losses that normally occur in a central HVAC system. Ductless systems also must meet the same minimum standards for central air conditioning systems and heat pumps. Ductless Mini-splits often have their own thermostat, so when you’re not using the area, you can turn it off, which offers greater energy savings, just like a central zoning system does.


Ductless systems require a professional HVAC contractor for installation. Once you decide where to place the air handler and the condenser, the technician will drills a three inch hole to run the conduit to connect the two. The refrigerant product for a ductless unit is installed at the factory. Once installation is complete, the technician will check the level and verify all the electrical components perform according to specification.
