How to Choose an Energy-Efficient Air Conditioner

Outdoor air conditioning unit sitting outside of Cayman Islands home.

A properly-functioning AC is integral to your home’s comfort. Nonetheless, you want more than basic comfort from your air conditioner—you expect convenience, adequate cooling capacity, and high energy efficiency.

With so many different ACs in the market nowadays, you might be asking yourself: what are the most energy-efficient air conditioners?

From central air to ductless systems and everything in between, HVAC companies boast energy efficiency as a top asset. But are energy-efficient air conditioners worth it? We’ll answer these questions and more.

The Benefits of Energy-Efficient ACs

So, are energy-efficient air conditioners worth it? Most homeowners would say, “yes.” When you install an AC with high energy efficiency, you will:

  • Use up less energy
  • See savings on your energy bills
  • Be more environmentally-friendly

These benefits, which can be great for your wallet, definitely mean that energy-efficient air conditioners are worth it. Nonetheless, you’re probably still wondering what the most energy-efficient air conditioners are—namely, which one is best for you.

5 Factors to Consider

Before we dive into discussing what the most energy-efficient air conditioners are, let’s first discuss what you should look for in an AC. There are five main factors you should consider.

  • The Size of Your AC

Your home requires a properly-sized AC. If your air conditioner is too small, you risk not being able to cool your entire home. At the same time, an oversized AC will waste energy and lead to soaring energy bills—two things no homeowner wants.

  • SEER Ratings

Since we’re talking about energy efficiency, SEER ratings are essential. Look for an AC with a high (Seasonal Energy Efficiency Ratio) SEER rating. A high SEER rating equals high energy efficiency.

  • Cooling Capacity

Here in the Cayman Islands, your new AC system needs to have an adequate cooling capacity, and cooling capacity goes hand-in-hand with energy efficiency. An AC’s energy efficiency is measured in British thermal units (BTUs).

  • ENERGY STAR® Certification

If an air conditioner is ENERGY STAR® certified, that means the AC either meets or exceeds specific standards for energy efficiency. Always keep an eye out for this certification.

  • Overall Convenience

Does the AC you’re considering have a programmable thermostat or incorporate other innovative technology? With a programmable or smart thermostat, you can manually control your AC from your smartphone even while you’re away from your home. As a result, you can rack up energy savings

Ductless Mini-Splits

Let us discuss ductless mini-split air conditioning systems. Ductless mini-split systems are known to be highly energy efficient. Since these systems involve having indoor units for every room in your home, you can precisely adjust the desired temperature in each living space. This means that you’ll waste less energy in cooling rooms you don’t use.

You should consider a ductless mini-split air conditioner if you’re looking for a system that effectively cools your home. With a mini-split unit, you have cool air ready at your fingertips.

Central Air Systems

There are countless benefits to central air conditioning, including clean indoor air and silent operation. By design, central ACs always work to cool your entire home, and new units will blow your mind with incredibly high efficiency rates.

Inverter Air Conditioners

Inverter ACs are pretty new, but they are said to waste less energy than traditional types of air conditioners. At the same time, these systems are known to be more expensive to install than other ACs.

Call Us Today

While energy-efficient air conditioners are undoubtedly worth it, it’s not always easy to know which AC is best for you. At Polar Bear, our expert HVAC technicians know what the most energy-efficient air conditioners are. What’s more, we can help you choose an energy-efficient AC that fits your needs.

Leeron did an excellent job! Our air conditioner wasn’t working and needed to be replaced. He was able to get it working long enough to tide us over until the new unit could be installed which we really appreciated. He is very knowledgeable and professional. I would definitely recommend him!
Love my Polar Bear Family. They are efficient, professional, and keep me informed while taking care of my units. From booking my appointments to having the technicians attend to my service, it's a breeze!Roemaine is very friendly and knowledgeable.
We needed an urgent service of our a/c unit and Polar Bear came out the same day. Billy was fantastic and extremely helpful. We were very satisfied and delighted with the service that we received. Could not be more pleased.
Leeron was very friendly and efficient when he serviced our air conditioning unit. He was very skilled and a pleasure to be around. I would definitely recommend booking him again. Thank you for a fabulous job well done!
I am writing to express my appreciation for the outstanding service provided by your technician during a recent visit to my premises. The technician demonstrated a high level of professionalism and expertise, and I was thoroughly impressed by his knowledge and skills.Not only did the technician efficiently address the issue at hand, but he also took the extra step to reprogram my thermostat, ensuring that everything was in optimal working condition. His dedication to providing excellent service did not go unnoticed, and I am grateful for his efforts.Keep up the good work, and continue to exceed expectations with your exceptional service.
Thank you so much to the Polar Bear team (Tony and Fabian ( installers) Vic the technician and Kieran) for coming to our rescue after our indoor unit needed replacing. Emailed in the early morning hours to receive a phone call by 8:30 am and a technician in place by 10:00 am. Full unit was replaced same day. Great service. Highly recommend!
Had a new condenser and 3 mini splits installed by Polar and the job was amazing. Very pleased. Jerome and Marcelo did great work. My old unit finally gave out and Kerien gave me a fair quote and prompt install. 110%. A+ work from start to finish.
Very impressed with Polar Bear's service. Vic paid my apartment a visit this morning and was able to diagnose the problem right away. He is very professional and explained in excellent detail what's causing the issue, along with the recommended solution. When advised to proceed, he worked on the fix right away and was done before you know it. Highly recommended!
This was my first experience with Polar Bear and Dwayne, Jerome and Marcello went above and beyond to get our a/c installed and running so my family, including my two grandsons under 2 years old could be comfortable. They were very professional, personal, and kind while handling our issues (they even interacted with our dogs). THANK YOU SO MUCH! Your team and service were amazing! You have just gained a very satisfied and loyal customer.
"Five stars doesn't seem like enough for the exceptional service Billy always provides! Our business has an annual contract to maintain our air conditioning system and Billy always rocks-up with professionalism, expertise, and a friendly demeanour.From the moment he arrived today, it was clear that Billy knew exactly what he was doing. He conducted a thorough assessment of our system, explaining each step along the way so we understood the issues and the proposed solutions. His attention to detail was impressive, and he didn't cut any corners. We had a unit which has been rattling for two years... we didn't even think to mention it but, today we did and he fixed it by using a different filter! That simple!!!Not only did Billy fix the immediate problem with our air conditioning, but he also took the time to provide valuable maintenance tips to ensure our system runs efficiently in the long term. His dedication to customer satisfaction was evident throughout the entire service call.In addition to his technical skills, Billy's customer service was top-notch. He was punctual, courteous, and respectful of our business environment.Overall, I can't recommend Billy @ Polar Bear Air Conditioning highly enough for anyone in need of air conditioning service. He's a true professional who takes pride in his work, and it's clear that he genuinely cares about his customers' comfort and satisfaction. Thank you, Billy, for another job well done!"Tamara, BodyBarn MediSpa ;)
Just moved into my new home a few months ago, Polar Bear was recommended to me by a family member. Had our first servicing last week and Billy attended. Billy called as soon as he was done at the house with an update on his findings and was very helpful in answering all my questions and making solid recommendations to keep my AC system running efficiently. There is also Alice at the office who is very nice and helpful over the phone, giving quotes and taking payment.
I’ve heard many good things about polar bear I can say it’s and under statement. The professionalism and welcoming personality from technician Billy was truly commendable. He provided clarity on what he was doing and any further steps as it was my first encounter with the company. Would recommend Billy as your technician anytime.
Javier & George were my first experience w/Polar Bear AC today. I am very pleased as they took their time, were very meticulous in the work they did, were friendly and helpful, showed me their work and provided their professional opinion on the best onging care for my two AC units. I plan to ask for these two on my future maintenance visits. By the way, as Head of HR for my company, I always ask how vendors who work for me are treated as employees. Both Javier and George said this is the first company they have worked for that they enjoy coming to work each day as they feel they are respected and acknowledged for doing great work. They said they would go the extra mile for this company because they are treated well. To me, this says lot about how the company is run.
I'm leaving a 5 star rating for Billy who was kind and respectful to me and the house. He was professional made sure and told us everything he was doing before he done it. I highly recommend him for all your A/C needs.
Today, Billy came to our house to service our AC. We were impressed with the way he worked. He was very professional, respectful, and helpful in his comments. He made the effort to see that we were very satisfied and happy. Thanks very much for such great service, Billy and Polar Bear. Wishing you all the best for continued productivity and prosperity in 2024.
Billy did an awesome job. Very kind and hard working. Got my filters changed in a jiffy and had my ac smelling amazing. Would recommend him to anyone.
Billy is amazing, he is very polite, professional, and took time to explain tasks he completed to ensure that my AC was well serviced. His professionalism and diligence are very much appricated! Keep up the great work Billy!
First time using Polar Bear for servicing our AC units. From the get go, the technician Billy Pineda reached out to us and had the best attitude/client service! He was very respectful, friendly and extremely knowledgeable. Polar Bear, you guys have a top-notch employee and are very fortunate to have such a professional member of your team. I think you guys need to promote this guy to a Supervisor role as he checks ALL the boxes of what someone in a leadership role is supposed to be! Billy, if you read this, it was an absolute pleasure young man!
Great same day service by Travis! Very professional and polite. He took the time to explain to me what is needed to take care of my new home AC and got me set up for quarterly services. Thanks for a great experience Travis & Polar Bear!
Had our quarterly servicing just completed by Anthony. Extremely professional and friendly. He completed the work efficiently and made sure that I was made aware of any matters of importance. Highly recommend Polar Bear.
Excellent and professional service. Called up due a failed wall unit and Kieran came out the same day, assessed the situation and sourced us a new unit for next day installation. His installation team were efficient, clean, and went above and beyond with their work. I can thoroughly recommend using them for your AC needs.
Excellent customer service, very pleasant and knowledgeable provided a great explanation of the A/c condition and steps to correct the issue.. offered a good and manageable plan to meet the needs for replacing or correcting.Vic is an excellent asset to your company.
After showing up at midnight on a Saturday when our system crashed a few months ago (and I was not a customer then) I thought I would try a maintenance package. Just had the first service and it was a pleasure. Billy was our man and he was friendly and first-class. I also appreciated the scheduling and email/text msgs with updates. All well done.
Kieran was great to work with. Communication was great. He took the time to explain the service and the parts. I would definitely recommend him to anyone requiring AC service. He did a great job.
Billy recently serviced my AC for the first time. He called me when he was on his way and arrived promptly after. From start to finish he was very friendly and courteous. He was also very thorough and even took videos of the unit in my ceiling to show me exactly what he was doing and why.
My husband and had polar bear come out to service our ac unit. Travis Campbell was the tech who came out. He was exceptional, very professional and a great personality. He was very informative and helpful in explaining the procedure and what needed me to be done. We are very happy, especially with him and the service we received.
Thank you Travis for your exceptional services. Travis was very thorough in ensuring that my AC issue was resolved. He was very professional and very approachable, ensuring all my questions were answered and all my concerns addressed.
After having multiple AC issues over the past couple of years, Polar Bear was recommended to me. Fast, efficient service. Travis is very knowledgeable, explaining the problems to me very clearly, and making suggestions that would work with my budget. He and Lewis provided service with the utmost care and attention. Very pleasant and polite, easy to see customer satisfaction is important to these technicians. Highly recommend.
I have used Polar Bear for a couple AC jobs and have been very pleased. The in office staff is great at setting appointments and the repair folks are professional and knowledgeable. Prices are fair and it’s a done in one trip experience. They stay until the job is done. A+ 🐻‍❄️
Have always had great service from Polar Bear Air Conditioning. Travis, who serviced today, was sure to note any concerns during the servicing as well as suggestions to keep our unit in full operation.Will continue to have Polar Bear as our service provider for our AC.
The Polar Bear team has demonstrated exceptional service when we called them. We extend our gratitude to the following: Octavia for conducting a comprehensive diagnosis of our AC issue; Kieran for confirming the diagnosis and ensuring that all procedures were carried out to a superior standard. Additionally, to Marcel, Nathan, and Jerome who efficiently installed and completed the necessary tasks in a timely manner.
Today, Roemaine and his assistant came to our house to service our AC. We were very impressed with the way they worked. Roemaine was very professional, respectful, and helpful. Going way beyond our expectations to ensure that we were very satisfied and happy. This is a busy time for us as we prepare for the holidays but they were so unobtrusive, that we were able to get on with our tasks as if they were not there. Thanks very much for such great service, Roemaine and Polar Bear. Wishing you all a wonderful Christmas, and continued productivity and prosperity in 2024.
I recently had the pleasure of experiencing outstanding service from Polar Bear AC, and I can't speak highly enough about the technician, Billy. From start to finish, the service provided was excellent.What set Billy apart was his attention to detail and commitment to ensuring our family's safety and comfort. As he conducted the maintenance check on our AC unit, he took the time to explain each step thoroughly.What stood out was Billy's consideration for my family, especially my young kids. He asked questions and made sure that all safety measures were in place and that there were no potential hazards for children in the house coming from the AC, like mold or smells.His expertise and knowledge were evident with his recommendations on how to lower my electric bill. I highly recommend Polar Bear AC for their exceptional service.
Kieran, Marcelo, Natan and Jerome were great throughout the replacement of my A/c units. Professional, knowledgeable, neat and courteous!.. I started using Polar for a washing machine repair and now I will use them for everything!
Great customer service from Octavia and her work partner, his name slipped me now. They arrived on time and explained all the work they did and even made suggestions to improve my air condition systems and vents going forward.Thank you.
Octavia and Billy were both professional and explained the situations as they continued forth. I would like to keep them on my repair and service team going forward.Kieran was thorough and followed up with the diagnosis and I am waiting for the quotes for equipment and install.
Even though Vic is new to Polar bear and Appliance doctors he showed his many skills and great level of knowledge about the complicated issues I have been facing with a commercial fridge and freezer.The problems were swiftly diagnosed and when new issues arised he quickly tackled them with professionalism and explained everything in a simple way that was easy to understand.Larry also joined and is an exceptionally knowledgeable and experienced, witty guy who was great to work with.Thanks so much for the help!
Polar Bear did an entire system replacement in my home, everything from the consultation with Kieran through to the installation with Jerome, Fabian & Marcelo was handled professionally and they kept me updated daily with what they were doing.I was given some options to choose from and went with a new Bryant system with an Ecobee thermostat and am very happy with the new system and how efficient it is.Thank you Polar Bear for your great service!Scott
Everything was top-notch! Octavia and Billy were excellent in explaining and getting the job done. I couldn't have asked for anything more -I'm very happy with my first Polar Bear experience!
Leeron, the technician, was attentive and his work was clean and tidy. The installers, Tony and Natan, were great - very professional, diligent, polite and friendly. They went that extra mile to accommodate our personal circumstances. Kieran, the comfort technician, was very responsive and highly professional. His outstanding customer centered approach through the whole process ensured we were both informed and satisfied at all times. We would recommend Polar Bear to anyone considering a home installation or service maintenance.
The technician, Romaine, was very professional, knowledgeable and friendly. The only downside was it took 2 days before they could come because they were so busy but when they did arrive, their work was extremely good.
I have just had a totally professional interaction with 5 of Polar Bear Air Conditioning Staff.They were Octavia, Billy, Dwayne, Genome, and Tony.Octavia and Billy are two of their Service Technicians, Dwayne is a Installation consultant ( I think) and Gerome and Tony are Installation Technicians. All of them were professional, courteous, and extremely knowledgeable!I am very pleased with the work they did.
They need more technicians as I waited most of a day to have someone come and service my 2 ACs only to be told they wouldn't make it that day. They did reschedule to a Saturday morning and this time the tech was right on time and did a great job. He was very personable and showed me what was wrong and that it had been corrected. The tech deserves 5 stars but Polar Bear lost one for the wait.
Roemaine is a very pleasant and professional individual. He was proactive by calling ahead so that I could make arrangements to meet him for this emergency situation. He was punctual, upfront with the diagnosis and costs and explained my options. This made me feel like he was genuinely customer focused. Roemaine and his colleague resolved the issue promptly; big kudos to both of them.
My experience was a great one from start with the receptionist, she was very helpful which I greatly appreciated. Overall I was happy with the professional service provided, Pascale was great, arrived on time and took the time to explain everything. Keep up the good work and thank you very much.
These guys did a fantastic job, from start to finish. First the team of two introduced themselves and gave an explanation of what work they were going to do.This was a job well done from the correct size unit for the room to a neat installation and oh they even cleaned up before they left. Thanks again Polar Bear for an excellent job.
I am so grateful to Polar Bear Air Conditioning. I was smelling a combination of stale cigarette smoke and a wet dog for approximately 2 weeks and then the A/C unit stopped working on a particularly hot Friday night. I called Polar Bear and Mr. Gilbert Smith came out and he would not leave until he got the A/C to start cooling. He gave me his phone number and asked me to call him if it stopped cooling. Mr. Dwayne Ashley called me on Saturday morning and answered all my questions and reassured me that the unit would be fixed ASAP. My initial appointment was set for Tuesday morning but Mr. Dwayne called me on Monday morning to say that there was a cancellation. I had taken my vehicle to be serviced and Mr. Dwayne came to me to get the key to open the apartment. When I returned to the apartment, I was surprised with how well the team had cleaned up. Don't get me wrong, I still swept and mopped the floors, but it looked like what I would regularly do at the end of the week. Mr. Dwayne came by on his way home to collect payment. At the end of the day, I checked all the boxes for Polar Bear and I would highly recommend them to anyone. As a matter of fact, I have already recommended them to two people. Well done Polar Bear and thanks a million.
Romaine was amazing, very professional and responsive.He helped me out on a late friday afternoon and did not leave until my AC was up an running. Amazing, friendly service!The gentleman that he was training was also very professional.
Tyrone and Travis are professional, knowledgeable, honest, hard working and very pleasant to deal with. They came to install new thermostat units in the house and spent time to make sure that everything was set up properly and working with no issues. I highly recommend the 'T&T' team to all new and existing customers at Polar Bear. Thank you again for amazing service! Bibi & Nina
The team from Polar Bear Company came to replace our air conditioning unit, and they did an excellent job. From start to finish, their service was professional and efficient. The technicians arrived on time, well-prepared, and knowledgeable. They handled the installation with expertise, paying attention to detail and ensuring optimal functionality. Not only were they skilled, but they were also friendly and courteous, addressing my questions and concerns with clear explanations. Overall, the Polar Bear Company exceeded my expectations in terms of quality, efficiency, and customer service. I highly recommend their services to anyone in need of AC replacement or related work.
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!
Tony and Jerome were such amazing technicians during my first service with Polar Bear AC! They were diligent and very hardworking while also being extremely careful and considerate with the home during an AC unit dismantlement and full new installation of a downstairs home AC unit. They were very clean and tidy as they worked with protective carpet through the house and cleaned up throughly when the job was done. They were an example of best kind of people who taking pride and care as they completed their work. They did such an excellent job, i couldn't recommend them enough for future jobs!!!!! thank you Tony and Jerome for a job well done.
From booking the appointment, reminder notifications, calls prior to arrival, details of who to expect to the very staff who answer the calls, the service has remained exceptional. Value for money and the quality of work performed has always been at a high standard. Would certainly continue to use their services and recommend them.
Professional, timely, flexible, great customer service.I wish to thank Polar bear for the excellent service provided for ac work at my apartment. I truly impressed with the attention to detail and quality of work. I would happily recommend them to potential clients.
Octavia is very professional and it's a pleasure to see her when she comes to work on our AC systems. Polar Bear is extremely responsive to emails and phone calls and they provide a great service.
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.
Polar Bear technicians are always very polite, friendly and professional in their service. Each of their technicians that we have dealt with have been great and they are always super responsive to getting someone out. Pictured are Antony and Billy who completed our recent service 👍
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!
Tyrone is very knowledgeable and professional, he gave me a step by step update of what he was doing. He also gave advice on how best to protect not only the unit but my family. My wife and I are totally satisfied with the service.
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.
Olivia and Demitri very professional , competent and are delightful people! She came by and diagnosed some issues with our AC system . I am reviewing your estimate at this time..I truly enjoyed meeting them. They both real assets to your Company!Rob
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
