What is Ductless Heating and Cooling?
A ductless heating and cooling system (also known as a ductless mini split or mini split) is a unique heating and cooling system. This unit has two main components — an indoor air handler and an outdoor compressor and condenser unit. The indoor and outdoor units are connected through a conduit that holds a power cord, refrigerant and suction tubing, and a condensate drain. This system is adaptable and can create different “zones” for heating and cooling throughout your home.
HOW DOES DUCTLESS HEATING WORK?
Ductless heating systems feature a heat pump. The heat pump warms your home by moving warm air from the outside to the inside of your home. You are probably wondering how the heat pump gets warmth from cold winter air. Essentially, the heat pump takes refrigerant and moves it through an expansion valve. At that point, the gas becomes much colder than the outside air, and as a result, any heat that is in the outside air gets absorbed by the refrigerant. Then, the warmed refrigerant, travels into your home. When it gets to your air handling units, the units blow air over the warm refrigerant and that warm air is released into your home.
HOW DOES DUCTLESS COOLING WORK?
Ductless cooling is basically the reverse process of ductless heating. The refrigerant absorbs warm air from your home. Then, it carries that air outside and releases it. When the refrigerant returns inside to your indoor air handling units, it is cold. When air runs over the coils holding the refrigerant, the air cools down and in turn makes your home cooler.
Are Ductless Systems Efficient?
Ductless heating and cooling systems are more energy-efficient than other types of systems on the market. They can save you money because they use much less energy. They move energy rather than produce it outright. Additionally, you sidestep problems with ductwork leakage, which boosts your efficiency, and you can control every zone independently. This really cuts down on your energy expenditure.
WHAT DO DUCTLESS HEATING SYSTEMS LOOK LIKE?
The outdoor unit looks relatively similar to a conventional outdoor air conditioning unit. The indoor units are relatively small, and they come in a range of designs and colors so that you can match your existing decor. You can also opt for recessed indoor units if you don’t want them protruding from your wall.
WHERE DO YOU PLACE THE INDOOR AIR HANDLING UNITS?
Traditionally, the indoor air handling units go on external walls near the ceiling, but in some cases, you can put indoor air handling units on interior walls. You can also opt for units that go near the floor or ceiling units. Your installer will let you know which option is best in terms of efficiency and air flow.
HOW DOES ZONING WORK WITH DUCTLESS SYSTEMS?
Ductless systems are also called mini splits because you can split the amount of hot or cold that goes into various areas. Each indoor air handling unit features its own thermostat, and you can control each unit separately. Generally, you don’t just have to put a thermostat on the wall. Instead, you can have a remote control that lets you change settings without moving, and with some systems, you can even connect everything to an app for remote control regardless of where you are.
The zone set up means if you’re not using part of your home or office, you can turn off the heating or cooling in that area to save money. Similarly, if you need to keep one area warmer or cooler than the rest of your space, you don’t have to waste energy or electricity keeping other areas at that same temperature.
