How a Ductless Heating and Cooling System Works (Video)

Mike Cappuccio explains the components involved in a ductless heating and cooling system. He talks about the role of the indoor and outdoor units, and he details how they work together to heat and cool your home.

Hello, I’m Mike Cappuccio with Jones Services and I’m here today to tell you how a ductless heating and cooling system works. I’m also going to explain what’s composed of the parts to put it together to put it into your home.

The first thing is a condenser that goes outside. Inside of the condenser, it has two major components, a compressor and a condenser coil. This piece will be placed outside your home.

In between the outdoor unit and the indoor unit, which you see above my head here, are these two sets of pipes, two refrigerant pipes. One is high pressure, one is low pressure, that would run from the outdoor unit to the indoor unit.

Refrigerant travels through the lines up into the evaporator of the indoor unit. The fan then runs. Cold air blows out of it or warm air blows out of it depending on the season of which you’re using it for, either heating or cooling.

Everything is controlled by a handheld remote control. You can use wireless controls as well behind me here. So depending on the application and what type of controls you’re looking to install, it can be used with either or.

It’s composed of some components of the outdoor unit, the indoor unit, and a line set that goes between them. From there there’s also electrical that needs to be hooked up to the outdoor unit. That would come from your existing electrical panel inside of your home. We would run wiring from your panel to an outdoor disconnect switch, which would then run the power into the unit right here to power up this unit, and then the power from the outdoor unit provides electricity to the indoor units and away you go. Take the remote, press the buttons, and get cool or get warm.
