A ductless heat pump is an air conditioning system that also heats your home.
It simply reverses its refrigerant cycle from cooling to heating, providing consistent home comfort, no matter what the temperature is outside.
Ductless Heat Pumps are often referred to as Ductless Mini Splits, Ductless A/C, Ductless Wall Mounts, Air Handlers, Ductless HVAC systems, Mitsubishi Mr. Slim and the list goes on.
A traditional ductless heat pump systems consists of one or more indoor wall mounted units with one outdoor unit.
The indoor unit and the outdoor unit are connected by refrigerant piping, run through a small 3" hole, hidden by the indoor unit. The refrigerant flows from the outdoor unit to the indoor unit, providing either hot or cold air into the room. A remote control allows you to set it to heat, cool or dehumidify. You can also set it just to circulate the room air.
A ductless heat pump system is also a very efficient “zoned” air conditioning system that can also be used as your main heating system or as a secondary source of heat, using a fraction of the energy of traditional central air and heating systems.
This is why so many homeowners and businesses are switching over to ductless heat pumps for their total HVAC comfort needs.
A Ductless heat pumps have been around for over 25 years but they were not very efficient back then. Today’s ductless heat pumps are designed for maximum efficiency and comfort. They are designed to keep the room temperature at a constant comfort level, using the least amount of energy, while keeping your electric bill low as possible.
All of this is accomplished by the new Inverter Technology. Inverter technology allows the system to ramp up and down, depending on the outdoor temperature and the desired temperature inside your home. Ductless heat pumps are the way of the future.
In hot weather, the refrigeration cycle is simply reversed and the heat pump becomes a traditional high efficient air conditioning system. The refrigerant inside of the heat pump carries the hot, humid air from the inside of your home and sends it outside, cooling and dehumidifying the interior living space.
You can heat and/or cool just one room or multiple rooms. Up to eight indoor units can be connected to one outdoor unit. Each room can have different temperature setting, depending on what that particular persons comfort requirement is. An open area can many times require only one indoor unit, such as a Living Room, Kitchen and Dining area. The rule of thumb is... If the room has a door, such as a bedroom, it will need its own indoor unit. Most homes only require three to four indoor units and one outdoor unit to heat and cool the whole house.
