How Ductless HVAC Works


When it comes to ductless heating and cooling, we receive LOTS of questions. From pricing to operation and just about anything else you can imagine - we’ve gotten a question about it. And since this technology is quite new in the long scheme of things, we don’t blame you.

Today, we’re going to focus on one of the most frequently asked questions - how does ductless hvac work? So, here goes:

Ductless splits, also called "Mini-Splits" pump cooled or heated refrigerant directly to the wall or ceiling-mounted air-handling unit, and each unit has its own wireless electronic temperature control system, a.k.a., a remote.

Here's how the system works in a single room application:
1. The indoor unit uses refrigerant to cool or heat air and quietly pushes the chilled air it where you need it in your living space.
2. Refrigerant and electrical lines connect the outdoor unit to the indoor unit through a 3" opening in the exterior wall.
3. The outdoor unit's state-of-the-art heat pump cools or warms refrigerant and sends it back inside to the air handler, which continuously monitors the room for changes in temperature and sends conditioned air to the areas of the room that need it.

Perfect Applications For Ductless HVAC:

Sunrooms: they have an abundance of natural light, hence their name. For this reason, they need to be cooled and heated differently than the rest of the house.

Additions/Outbuildings: they’re often short room and lack the space required for bulky ductwork. A ductless system is a great solution.

Problem Rooms: some rooms of the house just aren’t used as regularly as others so why waste money heating and cooling them? With a ductless system you can turn off the air to these rooms and close the door to save money.

But we must admit, there’s a little more to it than that. So if you still have questions about how a ductless mini-split system works, feel free to give the friendly electricians at GEN3 Electric a call today and don’t forget to connect with us on Facebook!
