Ductless AC in Louisville, KY

You may have heard about mini-split systems, otherwise known as ductless systems, but you may not be familiar with how they operate. Let’s explain the process in more detail so that you can determine if these systems might suit your home.

Ductless ACs Work Like Heat Pumps

Ductless air conditioners keep a home cool by transferring heat energy from the inside to the outside. This is precisely what any heat pump does. There are three main components: the air handler inside, the compressor outside, and a refrigerant line connecting the two. The only difference is that a mini-split comes with no vents; the reason is that a mini-split cools a single room, not the whole house.

Zoning and Directional Airflow

The air handler portion of a ductless system attaches to the wall, and the refrigerant line comes in through a three-inch hole made in the wall. The compressor can stand as far as 50 feet away from the air handler. To one compressor, you could connect up to eight air handlers, which can practically mean whole-house cooling! What’s even better is each air handler comes with its own thermostat, so you and your family members can adjust the room temperatures however you like. This is called zoning.

A mini-split gives you the ability to direct airflow, too, for maximum comfort and savings. If you hire Murphy Company Heating & Cooling for a mini-split installation in Louisville, KY, we’ll explain all the ways you can get the most out of this system.
