A Quick Guide to Prepare for Your Mini-Split AC Installation

Mini-split AC systems (also known as ductless AC systems) provide an effective alternative to traditional central HVAC units. The popularity of mini-split AC systems has seen a sharp rise in recent years due to the advantages offered. 

A mini-split AC system does not need ductwork installation and is easier to install anywhere in your home. It is a viable option for smaller homes, where it is impossible to install ducts or residents want more control over indoor unit placement and temperature settings. Homeowners can install multiple mini-split units, and each unit operates individually. People usually install them in spare bedrooms, sunrooms, new home additions, home offices, finished attics, garages, and apartments. 

What is a mini-split AC system?

Mini-split AC systems consist of a compressor or condenser located outside and an indoor air-handling unit connected with a conduit. These systems are compact, affordable, versatile, easy to install, and highly energy-efficient, provide greater flexibility, improve indoor air quality, lower utility bills, produce less noise, require less maintenance, and provide zoned cooling.

However, there are some factors that homeowners should consider before installing a mini-split AC system.

Size

The BTU output or the cooling capacity determines the size of the mini-split AC unit. An air conditioner professional can help in sizing the unit correctly to suit the home’s needs. For smaller spaces, a less powerful system works efficiently. Homes with poor insulation or high ceiling require a system with higher BTU.

Number of indoor blower units

A homeowner also needs to consider how many units the home requires to efficiently cool the space evenly, depending on the comfort needs. Consider if every room requires a separate blower or if placing two or three indoor units generally will provide adequate cooling. Consult a professional to figure out the correct number of blower units for maximum comfort and energy savings. 

Energy efficiency

Consider the SEER rating of the mini-split AC system before installation. A higher SEER rating translates to more energy efficiency and low carbon footprints but increases the system cost.

Indoor and outdoor unit location

Another vital decision the homeowner has to make is where to place the units to optimize cooling. Choose a location that ensures maximum air distribution. Place an indoor unit eight to ten feet from the floor while ensuring easy accessibility for cleaning. Avoid placing the blower near a heat source. Install the outdoor unit in an open space, where there is no obstruction blocking the heat dissipating from the condenser. 

Source of power

Before installing a mini-split AC system, ensure that the circuit that will provide electricity to the unit is not underpowered. It will keep the system working correctly and efficiently. Call an electrician to install a dedicated circuit to avoid issues.

Wall strength

Ensure that the wall where the mini-split AC system will be mounted is strong enough to hold the air-handler. Installation on weak, uneven, or false walls can lead to a severe accident. An installation done right the first time also helps in saving money.

Also, consider factors like distance between the two units and the space between the wall and air conditioner.
