Is a Mini-Split System the HVAC Solution for You?

Do not let the small-sounding name fool you. When it comes to heating and cooling, a mini-split system packs a big punch and can lower your home energy costs.

What Is a Mini-Split?

A mini-split is a ductless, smaller version of a central air system. You have likely seen one in action. They are common in room additions, basements, sunrooms, apartments and commercial spaces, and they are a popular retrofit for homes with non-ducted heat like hot water, radiant panels or space heaters.

Like central air, a mini-split has two main parts: an outdoor compressor and condenser, and an indoor air handler. Unlike central air, it lets you control the temperature of the individual rooms where it is installed.

Mini-Split vs. Multi-Split

A single mini-split regulates one temperature zone. A multi-split connects several indoor units to one outdoor unit, so you can set different temperatures in different rooms without multiple systems. An experienced contractor or design-build specialist can help you choose the right setup.

Advantages

• Room-by-room comfort: control the temperature where people actually are, so everyone stays comfortable.
• Energy savings: you are not heating or cooling empty rooms, and timers let you start cooling before you get home or warming before your alarm goes off.
• No duct losses: ductwork, especially in attics or unfinished basements, can waste a significant share of heating and cooling energy, according to the U.S. Department of Energy. Ductless systems avoid that loss.
• Design flexibility: slim indoor units can mount on a wall, hang from the ceiling or sit on the floor, and most come with a remote.

Disadvantages

• Existing ductwork: if your home already has extensive ducts, it may make more sense to expand the central system. A cost-benefit comparison helps.
• Upfront cost: mini-splits save energy over time but usually cost more up front than central HVAC per unit of capacity, especially when you need several units or large areas.
• Appearance: newer units are quiet and sleek, but some homeowners do not like the look in certain rooms.

Proper Sizing and Installation Matter

Correctly sizing and placing the indoor unit is crucial for temperature and humidity control and for cost. A system that is too large costs more up front and over time. We have extensive experience designing rooms around mini-splits and installing them correctly. For more ways to save, see tips to reduce energy costs at home.
