How Does Ductless Mini-Split System Work?

If you’ve got a house in San Antonio with certain spaces that aren’t heated and cooled by your central HVAC system, you may want to consider a ductless system to provide exceptional comfort in every room in your home. Of course, there are many other ways that you can utilize a ductless system beyond supplementing a central HVAC system. To best determine how you can use ductless mini-splits in your home, it’s important to understand how they operate by using this guide from Rosenberg Plumbing & Air.

Keeping It Comfortable Year-Round

It’s important to understand that a ductless mini-split system offers both heating and cooling capabilities. In a mild climate such as the one found in San Antonio, a ductless system is an excellent option because the system pumps heat from the outside air to heat your home during the winter. This means that you can enjoy reliable and economical home comfort throughout the year delivered from an easy-to-maintain system.

A Central System, Compacted

When you break down the various components of a ductless mini-split system from Rosenberg Plumbing & Air, you realize that these systems work in much the same way as a typical air-source heat pump installed in a central HVAC system. There are two separate units that make up a ductless system. One unit is located inside your home and the other outside. The indoor unit contains a blower fan, filter, and an evaporator coil. The outdoor unit contains the compressor.

When the system turns on, the blower fan draws in unconditioned air through a vent on the bottom of the indoor unit. While inside the indoor unit, the unconditioned air flows over the evaporator coil. Depending on whether you’re heating or cooling your home, the evaporator coil either expels heat into the unconditioned air or draws heat out of the unconditioned air using refrigerant inside the coil. Then, the refrigerant makes its way outside, where the pressure differential created by the compressor allows the refrigerant to either expel or absorb heat before it makes the return trip back inside your home.

No Ducts Allowed

Although a ductless system from Rosenberg Plumbing & Air has most of the same parts as a typical HVAC system, there’s one major component it doesn’t have: ducts. Rather than pushing conditioned air through a network of ducts, a ductless system accelerates the air so that it can push it directly into a single room. This simple approach to air distribution avoids the problems commonly associated with ducts, including dust accumulation, mold growth, air loss, and more. Plus, if you need to heat and cool a room that isn’t already supplied by a duct, a ductless system offers a less expensive option versus adding another branch to your ductwork.

Choosing a Ductless System

When you choose a ductless mini-split system for your home, you want to be sure to keep several factors in mind, the most important of which is size. Make sure to measure the room’s length, width, and height so that you can find a ductless system that provides the proper heating and cooling capacity.

The good news is that ductless systems are clearly marked with their heating and cooling capacity, which is typically expressed in BTUs. It’s important that you don’t choose a system that’s too large for your room so that your system doesn’t suffer from short operating cycles. Over time, this could cause extra wear on your system and require early replacement by Rosenberg Plumbing & Air.

Easy Operation

If you can operate a television, you can operate a ductless mini-split system. Since the indoor unit of a ductless system is typically mounted high on a wall, most systems utilize a remote control to allow you to change the temperature and control other functions on the system. This means that you can easily change the temperature in the room without getting up from your favorite chair. Additionally, if you have an elderly loved one who struggles to understand how to operate today’s modern thermostats, a ductless system with a simple remote control makes a great alternative.
