Steps to going ductless

Schedule an In-Home Consultation

Prior to installation, select a qualified contractor to visit your home and help determine the best system size and equipment placement. Additionally, some regions may require a pre-approval in order to qualify for utility incentives. To find a qualified contractor in your area, click Find an Installer to your right.

Select & Size Your Unit

Ductless systems are sized to meet the heating and cooling needs of a home’s individual zones. System sizing can vary as one indoor unit can provide between ¾ and 2 ½ tons of heating or cooling depending on its British thermal units (BTU) capacity rating. Outdoor units are sized to meet the combined load of all heating and cooling zones. More than one outdoor unit may be necessary for multi-zone systems.

Set the Outdoor Unit

The outdoor unit will be installed by your contractor outside your home on a level pad, close to the wall where your indoor unit will be located. The outdoor unit consists of a condensing coil, an inverter-driven variable speed compressor, an expansion valve, and a fan to cool the condenser coil.

Run the Refrigerant Line

A refrigerant line is made of insulated copper tubing and is housed in a conduit alongside a power cable and a condensation drain. Before refrigerant is circulated throughout the system, a pressure test is performed to ensure that there are no leaks.

Install the Indoor Unit

Your contractor will install the indoor unit high on a wall in your home's main living area. The indoor unit contains an evaporator and a quiet oscillating fan to distribute air throughout the heating zone. The outdoor and indoor units are connected by a bundle of cables through a 3 inch hole. The outdoor unit is then tied to your home's electrical system.

Connect, Start, Operate

A remote control is included with your system to set the desired temperature and program night-time settings. Ductless systems require basic maintenance to ensure optimum performance including keeping filters and coils clean. These tasks can easily be performed by the homeowner. The entire installation process typically takes less than two days.
