Are Ductless Mini-Split Air Conditioners Energy-Efficient?

Two women sitting on the couch enjoying cool air coming from their ductless mini-split.

If you’re in the market for a new air conditioner, you’re most likely considering many factors before you make the big purchase. For instance, you’re probably weighing costs, convenience, effectiveness, and—most importantly—energy efficiency.

Whether your home doesn’t have ducts or you’re looking for a satisfactory way to cool the place, ductless mini-split systems may have caught your eye. But are ductless mini-split air conditioners energy-efficient? And if so, are mini-split systems more energy-efficient than central ACs? We’ll answer these questions below.

Are They Energy-Efficient?

In today’s HVAC market, energy efficiency is a big deal. As such, you want a system that will waste less energy while providing you with effective comfort. So, are ductless mini-split air conditioners energy efficient?

Generally speaking, the answer is a resounding “yes.”

As systems with some of the most advanced HVAC technologies, mini-split air conditioners are known to be energy efficient. Since they’re ductless, you don’t have to worry about energy losses caused by faulty ductwork. According to the U.S. Department of Energy, ductwork energy losses can be to blame for more than 30% of AC energy consumption.

Advantages of Energy-Efficient Systems

Now you know that ductless mini-split air conditioners are energy efficient. But are some mini-split systems more energy-efficient than others? The truth is that ductless mini-splits can vary in efficiency.

To guarantee efficiency, look for ENERGY STAR® certified systems. An ENERGY STAR® rating means that the unit meets certain federal guidelines for energy efficiency.

One of the most enticing draws of energy efficiency is the savings they can provide. A highly efficient system can save you money on your energy bills.

Plus, with energy-efficient cooling systems, you can:

  • Waste less energy
  • Prevent wear and tear
  • Avoid unexpected repairs
  • Increase HVAC system longevity

Other Benefits of Mini-Split ACs

Efficiency isn’t the only advantage to installing a ductless system. Mini-split systems are used to cool your home, plus they are considered convenient and easy to install. As ductless systems, no additional or existing ductwork is needed. All you need is an indoor and outdoor unit. This means these systems are overall much easier to install than a popular alternative: central air.

When you need a new AC system in the Cayman Islands, you want an air conditioner you can fully control.

If you wish to choose which rooms to cool, mini-splits are a great choice. Each room has its own indoor unit that can be controlled individually to fit your specific needs. 

Mini-Splits Vs. Central Air

No one wants an AC that wastes energy. So, here’s the big question: are mini-split systems more energy-efficient than central air? The energy efficiency of air conditioners depends on the SEER rating because the higher the SEER rating, the more energy-efficient the system will be. Both mini-split systems and central system can have a SEER rating that ranges from 12 SEER up to over 20 SEER.

While mini-splits can sometimes have higher SEER ratings than central air, there are benefits to central air systems that shouldn’t be overlooked, such as convenience, reliability, and indoor air quality. Central units are quieter and less intrusive than mini-splits, making them ideal for a wide array of households.

Factors to Consider

Central air conditioners are the preferred choice for most homeowners because they are known to last much longer than their mini-split counterparts, making the overall lifetime value of central units much higher.

If you’re wondering if ductless mini-split air conditioners are more energy-efficient than central air, there are other important features to consider. When deciding on an AC replacement, don’t merely consider energy efficiency—also consider performance, dependability, and other factors that pertain to your specific needs.

I recently had my air conditioning unit installed by Polar Bear Air Conditioning in Cayman Kai. I was very pleased with the service I received. The workmen, Jerome, Tony, and Nathan, were all professional and courteous. They arrived on time and were dressed in their uniforms. They laid out carpeting where they would be walking inside the house to avoid leaving debris or making a mess. They worked clean and kept the space tidy. They were polite and provided me a good understanding of the work they completed as well as showed me all pieces of equipment. They emailed me a jpg image of each piece of equipment's information plate so that I could record it in my home management software, as requested.Here are some specific details about the work they did:They installed 3 new high-efficiency air conditioning units that are much more energy-efficient (26 SEER) than my old units.They cleaned and disinfected the air ducts, as well as replaced previously installed flex ducts with rigid duct work that is superior in efficiency and durability.They installed new filters to help keep the air clean and free of allergens.They explained the operation of the new units to me and answered all of my questions.They cleaned up after themselves and left my home in good condition.I would highly recommend Polar Bear Air Conditioning to anyone in need of air conditioning installation or service. They are a professional and reliable company that provides excellent customer service.

Our ac stopped working a few weeks ago and Polar Bear sent Roemaine and Tyrone to diagnose the problem. Roemaine and Tyrone very quickly identified the problem and communicated with me. It turns out the best option was replacing the condensing unit which Paul quoted within a matter of minutes and they had expert installation team (Tony and Jerome) complete late in the afternoon with short notice. I’m very happy with their work!

I have, over the years been trying to find a reliable, professional A/C maintenance and repair company. I have tried a few. That search is now over after using Polar Bear. Billy and Jerry were absolutely a pleasure to work with. Knowledgeable and professional from the initial diagnosis to the final repair. I highly recommend this company and the team that came to do work on my AC. Tim.

Great work. I received an email and also a call from the dispatcher that the tech would be calling me, and sure enough, the tech (Simon) called shortly after that to let me know he was on his way which was very much appreciated. The customer service from all of the team and updates was spot on, and Simon was very thorough and very knowledgeable. He was also very courteous and professional. I rate Polar Bear as the best company in town. Great work!

Polar Bear's service and response was amazing! Nicole who answered my phone call and scheduled me was extremely friendly, accommodating and knowledgeable! The Technician assigned to me was Simon and he was also extremely friendly and very knowledgeable. Within a minute of looking at my system he knew what the errors and issues were! He was able to fix one of the two problems that day, and then came scheduled and came the following day to fix the remaining issue. He was perfectly on time and the courtesy call before arrival both times before arriving was a welcome touch as it made sure that I was ready.Will continue using polar bear for all my HVAC needs! 5*

My experience with Polar Bear has been awesome!!!! From the beginning, the office staff were so professional and kind, then receiving my AC quote, the gentleman has been very prompt in his response time—, the kind of employee that puts customer first and has such a nice and an approachable attitude, very patient in answering my questions and providing guidance as required by me- customer focus completely, then as if that wasn’t enough to convince me to move my AC maintenance and installation to Polar Bear; the technicians that attended to my AC installation provided such excellent service— what stood out was how they used a carpet that was placed on my floor to avoid making any mess on my floor and whatever mess they did make, the technician used their broom to remove it. I know this message is long but I really wanted to express my THANK YOU and appreciation for such excellent customer service that I’ve experienced by Polar Bear — you have won me as a customer!! THANK YOU! Keep up the excellent customer service!!! Looking forward to building a relationship with you as a new customer.

I am very pleased with the service that was provided by Polar Bear. I had an issue where the ac was not working at one of my rental properties after hours on a weekend. Rohan came all the way out to East End at 10pm and worked on the issue to get the system back up and running. He was very thorough and explained the issue in detail, and the measures I needed to take to prevent it from reoccurring. Excellent customer service
