How Efficient Are Mini-Splits?

For most modern homes, a heating and cooling system is essential. However, with so many types of HVAC systems to choose from, many find it difficult to identify the best system for their living space. In this article, we will discuss the efficiency of mini-split systems and how they can benefit your heating and cooling needs. 

At Anderson Air, we understand how important a good HVAC system is. In this blog post, we’ll look at what mini-splits are and whether or not they’re an efficient option for your home. Let’s get into it. 

What are mini-splits, and how do they work? 

Despite what you might think upon hearing the name, mini-splits have nothing to do with bananas and ice cream! A mini-split is a type of HVAC system consisting of two main components: an outdoor compressor unit and one (or more) indoor unit that delivers the air called “air handlers”. 

They are often referred to as ductless mini splits since they do not require ductwork to disperse air throughout a home. 

Mini-splits transfer heat between the indoor and outdoor units through refrigerant lines via a heat pump to either extract or release heat depending on the desired temperature. This allows them to provide both heating and cooling capabilities in one system.

How efficient are mini splits for cooling and heating?

Ductless split systems have grown increasingly popular due to their efficiency and versatility. These systems feature an outdoor compressor/condenser unit connected to multiple indoor air handlers for zoned temperature control in a home. 

Not only do they eliminate the need for ductwork, they also provide more efficient heating and cooling. If certain rooms aren’t used often, the system can simply be shut off for that zone while continuing to deliver heating/cooling to every other zone. Cool right? 

A targeted system provides significant energy savings and lower utility bills compared to conventional central HVAC systems.

Mini-splits also tend to be more energy-efficient since they don’t suffer energy loss like traditional ducted systems. An estimated 30% of energy used is lost with ducted systems. By avoiding this, split systems are both economical and environmentally friendly. 

With rising energy costs and a global shift towards sustainability and environmentally friendly practices, choosing a mini split unit is a smart, energy-saving choice. 

8 Factors affecting mini-split efficiency

Here are a few factors that can affect the efficiency of these systems: 

  1. Location of indoor and outdoor units: The placement of indoor and outdoor components will directly affect their overall effectiveness. Areas with too much heat or sunlight can lead to higher energy consumption and impeded performance. 
  1. Size and capacity: To maximize energy efficiency and minimize cost savings, select an appropriately-sized mini split system. An undersized unit is forced to work harder to cool and heat a space, increasing energy usage while decreasing efficiency. Conversely, an oversized one may lead to short cycling.
  1. Insulation and climate: Good insulation is the backbone of any HVAC unit. Weakly insulated buildings can result in air leaks that force your system to work harder to keep the desired temperature constant. Also, consider your climate. These systems are designed for both hot and cold climates; however, extreme temperatures could affect efficiency. 
  1. Maintenance and usage patterns: Regular maintenance is vital to ensuring the efficiency of any system. Dirty filters, clogged coils and other issues can diminish efficiency while increasing energy consumption.

Frequency and duration can affect its efficiency as well. If a system is always running at extreme temperature settings, it will draw up more energy, and its efficiency will eventually suffer.

  1. Quality of installation: Proper installation is absolutely crucial to the efficiency of a mini-split system, as improper setup could result in air leaks, insufficient temperature control and other issues.
  1. Age and condition: As is true with any piece of equipment, age and condition can have an effect on its efficiency. Aged systems don’t typically perform as well as newer models – they may need more upkeep to maintain their effectiveness. 
  1. Energy source: The energy source you choose will also impact how efficient your system is. Solar and geothermal-powered systems, for instance, are often more cost-effective and environmentally-friendly options than electricity or gas. 
  1. Zoning: Split systems offer targeted heating capabilities that improve efficiency and comfort while decreasing overall energy usage. By taking full advantage of your mini split’s zoning abilities, you could significantly lower your energy consumption costs.

Before selecting any air conditioning system for your home, take note of the various factors that could impact its efficiency. Speak to an expert (like the pros at Anderson Air!) before making your final decision on one. Our technicians will guide you to the right system for your living space. 

Types of split systems

Ductless split systems come in various types. Here are a few popular ones: 

Single-zone: These mini-split systems contain a single outdoor unit connected to a single indoor unit that’s typically wall-mounted. It’s the ideal solution for smaller rooms, such as bedrooms in homes or buildings.

Multi-zone: A multi-zone system comprises an outdoor unit connected to multiple indoor units for zoned temperature control in various rooms. This option offers more cooling and heating control flexibility for larger areas with variable temperature needs/requirements.

Wall-mounted: As the most prevalent installation type, wall-mounted units are installed on indoor walls close to the ceiling. Their compact yet reliable cooling and heating power make them suitable for single-zone systems.

Ceiling cassette: These units are installed directly on the ceiling, blending seamlessly with any home decor. They are best for large open areas, providing excellent air distribution in large rooms. 

Concealed air duct: As the name suggests, this indoor unit is concealed within a ceiling or wall, leaving only a small grill visible. They are ideal for spaces with limited wall or floor space, providing a discreet cooling option that’s easy on the wallet.

Floor-standing: Floor-standing mini-split systems are free-standing units designed to be placed either directly on the floor or mounted to walls. They provide easy installation options and are perfect for rooms with limited wall space.

Pros and cons of mini splits 

  • Pro. Increased energy efficiency
  • Pro. Zone control for individual room temperature control
  • Pro. No ductwork means reduced energy loss
  • Con. While they save you money in the long run, upfront costs can get pricey. You’ll require professional sizing and installation to get the best out of your unit. 
  • Con. Some system types require a lot of room to install, while other, more compact options may not blend directly into your decor.
