Ductless Mini-Splits


A ductless mini-split HVAC system operates just like a conventional heat pump, providing both warmth and cooling as you need it. The difference is that instead of a single indoor unit that distributes heated or cooled air through ductwork, a ductless mini-split system has multiple small units serving individual rooms or zones. That makes it a great choice for room additions where extending or installing distribution ductwork is not feasible, as well as for older homes without air ducts.

In a mini-split system, a small heat pump compressor unit sits outside of your home. Connected to the outdoor unit are thin pipes filled with a refrigerant liquid. Similarly to a heat pump, the pipes transfer the refrigerant in either a liquid or gas form. The refrigerant pipes branch off to the separate rooms to be heated or cooled. The thin pipes are fed through the walls or ceilings to connect to a small head unit mounted in the ceiling or walls. A head unit containing a fan blows across the refrigerant pipes, delivering hot or cooled air into the rooms.

Quick Installation

Installing a traditional, ducted system can be a lengthy process that disrupts daily activities in the home. Ductless systems are far less invasive to install, and depending upon the number of indoor and outdoor units required, can be up and running in as little as one day. Mini-split systems run on small pipes that require a mere three-inch hole. That means homeowners don’t have to worry about rebuilding walls or ceilings around ductwork and there is no loss of precious square footage.

Save Money

One of the biggest reasons why homeowners switch to ductless heating and cooling is overall cost savings. Ductless heating and air conditioning systems operate on less power – they are smaller than traditional forced-air systems, and because the temperature-controlled air is delivered directly into a room, there is no loss in efficiency. Multi-split systems also allow homeowners to create “zones” in their home, which means they no longer have to cool or heat rooms that aren’t occupied.

Flexible Solutions

Whereas traditional heat pumps and central air conditioning systems force cooled and heated air through ducts, ductless heating and cooling systems deliver air directly into different zones. They are comprised of a small outdoor unit and one or more indoor units that require nothing more than mounting capabilities and access to electricity. They can be installed in home additions, new construction, condominiums and apartments, or to improve temperature control in specific rooms.

Air Quality

Oftentimes with ductless systems, the quality of indoor air can actually be lower than the quality of outdoor air. With traditional HVAC systems, air ducts must be professionally cleaned on a regular basis and, even after cleaning, dust and allergens are left behind. Ductless air conditioning and heating systems, on the other hand, offer multi-stage filtration that can drastically reduce dust, bacteria, pollen, allergens and other particulates in the air.
