How Many Amps Are Required for a Ductless Mini Split System

How Many Amps Are Required for a Ductless Mini Split System

July 26th, 2021


There are many factors that go into the installation of an air conditioning system, and a ductless mini-split system is no exception! If you’re considering adding this as a cooling–and heating–option, then this blog post is for you!

One of the factors included in ductless mini split installation is how much amp is required for it. This is the unit used for measuring electricity, or how fast electric current flows. The higher the voltage, the lower amps are needed, but how many amps are actually required for a ductless system?

This will actually vary, based on how many British thermal units, BTUs, the system uses–usually 15-45 amps per mini-split is needed.

Is all of this making your head spin? We get it! And we get amps, voltage, watts, and the like. We’re expertly trained and have the experience necessary to make sure that your home is matched with the right air conditioner for your specific comfort needs, and if that happens to be a ductless system, that it has the right amount of amps.

With that all said, you’re probably wondering if this truly is the right system for your needs. Read on as we uncover some benefits of such an installation!

What Makes a Ductless System Different?

A ductless mini-split system, also referred to as a ductless heat pump, operates a bit differently from a standard central air conditioner. Some qualities are the same. For instance, in the cooling season, the refrigerant-cycling process helps your system draw hot air out of the home and return chilled air.

Ductless systems operate on heat pump technology though, so they have a component called a reversing valve that allows the flow of refrigerant to go in the other direction.

What does this mean? Well, that you can use the system for heating as well, and very efficiently in a climate like ours!

Zoned Cooling and Heating

The other thing that makes a ductless system different from a standard central air conditioner or even a standard heat pump is its setup. The reason it’s given the name mini-split is that its components are split up and can work independently of one another.

There is one outdoor unit, and this is connected to up to 4 indoor air handlers that can be mounted up high above the doors in the rooms where you need cooling, and heating. There’s no ductwork involved, as the name implies. Instead, each air handler has a conduit behind it that goes through your drywall to the outside unit and contains a power cord, a refrigerant line, and a condensate line.

The Benefits

The benefits of this different setup include:

Versatility: As we mentioned above, these systems can be used for both your cooling and heating needs. They do best in climates with hot summers and mild winters, like our climate!

Efficiency: Since each air handler can be used independently, you can keep some rooms cooler or warmer than others. You don’t have to condition the whole entire house or argue with household members over what temperature to set the thermostat to. This is far more efficient and therefore lowers your cooling bills.

Convenient: Nobody wants an unexpected AC repair need. The good news with a ductless system, however, is that if one air handler is malfunctioning or has broken down, you still have cooling provided to you throughout your home.

These are just some of the benefits of having a ductless system installed! Please don’t hesitate to reach out to our team with any questions you may have.
