What is a Mini Split System?

Adjusting Temperature on Mini Split AC System

Mini split systems are all-in-one ductless units that provide both heating and cooling. Mini splits are a popular heating system in the Phoenix area because they’re energy efficient, quiet, and can be set to different temperature zones. A mini split differs from a traditional central air conditioning system because they don’t require ductwork. This flexible heating and cooling option can be installed in various locations without structural changes to walls or ceilings. 

At 1st Choice Mechanical, we offer expert AC installation of ductless mini split units. If you’re considering making the switch from a traditional duct-based central air conditioning system to a more efficient solution, we’re here to answer your questions. Read on to learn about the different types of mini splits and their benefits, such as energy and cost savings and better temperature control. 

How Mini Split Systems Work

Mini split units have evaporator coils that absorb warm air, then use refrigerant to cool and transfer the air through tubing to the outdoor component, which releases the heat outside. When you turn on the heat, it works in reverse — the outdoor unit removes heat from the surrounding air and pushes it back into your home. 

Unlike a central air system, mini split systems heat and cool areas depending on your setup. Central air systems have one indoor unit with ducts that send air throughout the house, while mini splits need indoor units in every space. Mini splits are best when used in smaller or enclosed spaces, such as a single room, home addition, or small apartment. 

Types of Mini Split Systems

Mini splits are small in size and split into two or more parts. There’s an outdoor unit and one or more indoor units, depending on if you have a single- or multi-zone mini split. 

The indoor pieces are mounted on the wall, under or in the ceiling, or on the floor as a free-standing unit. The outdoor piece should be on a solid, level area outside, with space for sufficient airflow into and out of the system.

Energy Efficiency and Cost Savings

One of the biggest reasons Phoenix-area residents are making the switch to mini splits is the improved energy efficiency. Mini splits transfer heat instead of using energy to generate warm or cold air. ENERGY STAR-rated mini splits use up to 60% less energy than some other HVAC systems, which minimizes your home’s ecological footprint and saves you money on your energy bills.

A mini split is an excellent cost-saving alternative to a central air system, which may lose energy by allowing conditioned air to escape due to compromised ductwork. 

Installation and Maintenance

Mini splits must be professionally installed. Improper installation could cause issues such as water leaks, a unit falling off the wall, or serious malfunctions. 

At 1st Choice Mechanical, our installation process includes choosing the best location for each component, properly and safely mounting all equipment, expertly connecting everything, and performing a complete inspection and testing. We’ll also stay to clean up after ourselves, perform a final test, and answer all your questions before leaving.

Mini splits should ideally be tuned up twice a year. Routine maintenance helps the system stay functional, clean, and ready to go when you crank up the AC in the summer or turn on the heat during chilly winter nights.

Our affordable maintenance service helps prevent annoying breakdowns and unnecessary repairs. We clean and inspect all indoor and outdoor components and lubricate moving parts. If you require repairs, we’ll let you know immediately and provide recommendations based on our expert opinion.

Zoning and Temperature Control

Installing numerous indoor units in your home, along with a thermostat with zoned temperature control, lets you heat or cool specific areas in your home to your preference. Temperature control conserves energy while giving you precise command over your comfort.
