Mini Split Installation in Placitas, NM

Terrence was wonderful to work with. His install of our new 40gal tank water heater is very clean and well done. I recieved quotes from 5 other companies in Albuquerque, all very well known, and Terrence gave me by far the best price and his work quality is much higher... Read More than my previous experiences with TLC and Affordable Plumbing. We will be using him for any future projects.

I called 3 HVAC companies, 2 were going to be a week or more. Terrence was over in about 2 hours. My pilot light went out, would not re-ignite and the blower was just staying on. After figuring out the problem, he spent the remainder of the hour doing checks,... Read More ie CO2. I will most likely use him to switch over my swamp cooler to refrigerated air.

Excellent Service — Honest, Skilled, and Reliable I had an outstanding experience with Air Efficiency Cooling and Heating Services in Santa Fe. Terrence, the owner, answered the phone when I called with questions about my thermostat and furnace. He was incredibly professional, knowledgeable, and patient. Remarkably, he tried to help me... Read More troubleshoot the issue over the phone with clear instructions—something few service providers are willing to do. Although it turned out I did need a house call, there were no appointments available that day. Terrence promised to reach out if he had a cancellation, and he followed through. He arrived promptly, was respectful in my home, and quickly diagnosed and fixed the heating issue. The fee was very reasonable, and for the first time in a long time, I felt I wasn’t being taken advantage of—a huge relief, especially as I often feel vulnerable when dealing with technical or home services. I was left feeling confident I’d chosen the right company. I highly recommend Terrence and Air Efficiency for anyone seeking honest, competent, and trustworthy HVAC care. You’ll see!

We cannot recommend Terrence and Air Efficiency highly enough. He was extremely professional from start to finish — punctual, respectful, and clearly experts at what he and his team do. The installation of my mini split system was done efficiently and with great attention to detail. The price was very... Read More fair for the quality of work and level of service provided. It’s rare to find a company that combines skill, professionalism, and genuine courtesy — he was truly a pleasure to have in my home. I highly recommend this company to anyone looking for top-notch AC services!

I highly recommend Terrance. Highest and dependable with experience and knowledge.

I would highly recommend Terrence from Air Efficiency to anyone looking for heating and cooling solutions. We had six LG mini splits that had been installed by another company and weren’t working to heat or cool our home. After talking with Terrence about the Mitsubishi mini splits, we decided... Read More to have him replace all of our old ones. He made a detailed plan and worked diligently to get the job done. In addition to Terrence‘s expertise, attention to detail and work ethic, he’s also a really nice guy. We felt comfortable with him in our home and our dogs were happy to see him every time he walked through the door. And now our house is cool and comfortable. Thank you so much, Terrence!

Recently, Terrence inspected my ailing and aging HVAC system--discovering important repair omissions and sheer sloppiness by the previous company. He has been officially adopted with great enthusiasm by our entire condominium! A rare experience: It was a pleasure.

Terrence Alm did an outstanding job of installing two condensors on my roof to serve five mini-splits. He was able to fit them within parapets that had concealed two swamp coolers. On more than one occasion, he assured me that they would not be visible from the street,... Read More which was an HOA requirement. In addition to delivering more efficient air conditioning and heating, he also addressed my aesthetic concerns about the placement of refrigerant and electrical lines as well as condensate lines. I did not want to mar the look of my adobe-style home. The original proposal did call for over the wall refrigerant lines, although Terrence said some through the parapet routing would reduce the jarring appearance. Once the proposal was accepted and work started, Terrance was able to use a small camera to explore the parapet cavities. He was able to propose alterations to the original proposal that allowed for lines to be concealed within the parapet walls and mini-pumps that would handle the condensate. The final outcome was no outside lines visible from the study, guest room and master bedroom, two of which faced the street. Only the living room and kitchen at the back of the property required minimal outside lines that went over the parapets. He collaborated with me on the placement of the mini-splits and made them look like part of the original building as opposed to an awkward add-on. I could not be more pleased in how the install turned out. Terrence's bid was higher than the other three I requested, but I was confident that he would deliver the best product. It is not everyday that you are meeting the CEO, who will also be doing the install. The representatives of the other companies were only able to offer off-the-shelf standard installs that did not touch the idea of parapet penetrations. Terrence is a mountain goat on the ladder, an artist in his approach to mini-split positioning, a techie in getting the install correct. He is also a gentleman and respectful in cleaning up after his work. He is building a relationship to back his product. Mini-splits are a major investment. However, they also add immediate value to a house whenever it is time to sell.

Making technology choices in almost any area of life has gotten harder and harder for the lay person. The product marketplace is flooded with choices, and there are few ways to separate fact from unsupported assertions. Sadly, choosing products based upon brand reputation is no longer a guarantee of quality. I... Read More wanted to add a smart thermostat to my home HVAC system to ensure that I could remotely monitor and adjust my system in the event that I was traveling if/when an extreme weather event arrived without warning. But honestly I didn't have a clue how to go about selecting a quality unit to meet my needs. Enter Terrence Alm - a good man with very significant HVAC expertise - to whom I could entrust both the selection and installation of the equipment necessary to achieve my goal. I recommend Terrence and Air Efficiency Services without reservation to anyone who, like me, wants a high quality technological solution to their HVAC needs.

I recently had the pleasure of working with Terrence Alm the CEO of Air Efficiency Heating and Cooling Services with the installation of a new three zone mini split heat and cooling system in my home, and I couldn't be happier with the experience. From start to finish, Terrence... Read More demonstrated exceptional professionalism, expertise, and customer service. There is a reason he is a Mitsubishi Diamond Contractor. Terrence also helped me find and coordinate an electrician for some needed upgrades to my old electrical system (more of the electrician below). The three zone system was calculated perfectly for my home is performing as expected and promised. The costs were as proposed and with 5% of other bids; frankly given the end product I would say was best priced by far. The installation process was smooth, efficient and transparent. Terrance would call or text with status every day and was extremely courteous working around me and my dogs. Terrence was so accommodating with the dogs that he made a new buddy, Shiloh the coonhound, for life. He took time to explain the system to me, the daily plans, issues and involved me with decisions along the way. Brilliant stuff. The quality of their work is outstanding. The exterior and interior work is so clean. Terrence takes pride in putting in systems that are unobtrusive and the final work is frankly seamless with the house. I also note that they left my house as clean as before every day. There were two issues that arose during the installation and both were handled transparently and professionally. 1) A ceiling insert could not be installed in one room because of the way the home was framed (never know what you will find when you start to open things up). Terrence involved and discussed with me immediately and found a great solution that I could not be happier with. 2) The main unit ended up having a board failure that Terrence identified quickly (this was late in the afternoon when starting the entire system up). Because he is a Diamond contractor and has a great relationship with Mitsubishi local representatives, he was able to get a new module the next morning and had it installed before noon. It was truly an exceedingly pleasant experience. They were responsive to my inquiries, provided clear and transparent pricing, involved me with decisions and worked issues without complaint. I cannot say enough about the excellent work and I highly recommend Air Efficiency Heating and Cooling Services LLC for anyone. Loya Electrical of Santa Fe installed a new exterior 200A load center and weatherhead system, placed new conduit and ground rods and pulled new wires under my house to my existing interior panel, plus the electrical disconnect/connection/power to the new mini split system. Octavio Loya and Terrence coordinated seamlessly and Octavio and his team did the work so efficiently when the county came to string and connected the new power feed my house I was only without power for less than an hour. The interior and exterior work is so good and clean that I can hardly tell if the work was done at all except for the new components. Electrical inspections went by without issue. As with Air Efficiency I highly recommend Loya Electrical. Adam Talmage Neill, PE Los Alamos, NM

Our AC stopped working and we called a big name company who quoted us over $20,000 because we "needed a brand new system." We decided to get a second opinion and I'm so happy we did. Terry came out in less that 24 hours after we called and fixed our... Read More AC in an hour. We will definitely be going with this company for any of our HVAC needs. February 2025- We contacted this company again for an issue with our water heater. I sent an email on a Sunday and I was met with a quick response. Terry was at our house Monday morning and fixed our water heater. He also checked our heating system and discussed options for updating our system. He was very knowledgeable and informative. We appreciate the prompt service and information provided. Thank you again for everything.

Terrance with Air Efficiency H&C is the most competent and responsive home service contractor we have worked with in a long time. We had no heat and could not get other places to respond - Terrance was there within 24 hours. The rates were also fair and transparent. Terrance was... Read More also very communicative, explaining the problem and the solution, and stuck to his timelines.

Terrence provides high-quality service and expert guidance, combined with great communication. While working on my furnace he noted a gas leak and immediately corrected the problem. I highly recommend him!

An expert in his field. I recently asked Terrance for a tune-up on my ac compressor unit. From start to finish it was like talking to a friend Excellent customer service

Recently added Mitsubishi ductless HyperHeat minisplits with Air Efficiency to my house, which was wood/pellet stove heat. I am very pleased with the job Terrence and his apprentice, Victor, did and very glad I chose Air efficiency (from 3 competitive bids). What stood out the most about Terrence was his... Read More willingness to discuss the options for outdoor and indoor unit placement with us, really listening to where we would like these placed versus the easiest installment for him. I can also say the team as a whole worked hard, showing up before 8:00 am and even putting a full day's work in on a Sunday to finish the job as quickly as possible. I would definitely recommend Air Efficiency if you are in the Santa Fe area and looking at mini-splits. I also highly recommend the Mitsubishi product line. I can not believe how quiet these things are!

Honest, reliable, and good communication.

Absolutely incredible service! Kind people that you can absolutely trust to get the job done and not take advantage of you. Extremely knowledgeable on a variety of topics. I will absolutely be using them for any service that I can for the rest of my life!

Terrence and Air Efficiency Heating & Cooling Services LLC did an excellent job installing our Mitsubishi unit. It works wonderfully, and we are very pleased. Terrence was very meticulous and his many years of experience were obvious. We highly recommend Terrence and his company.

Terri took his time to explain what he thought was happening even before I hired him. Alas I did not trust my gut and hire Terri to my regret. The other guy came out on a maintenance call, spent an hour diagnosing instead of maintaining leaving me with... Read More a proposal for $2,000 work and a bill for $200 to pay for his time drumming up business. Terri came out and was absolutely correct in his telephone diagnosis. He maintained the system, fixing the probable source of my problem very simply and said some of the proposed work did not need to be done at this time. My system is up and running at a $700 cost. Terri is honest in his assessment, makes reasonable suggestions, and put my mind at ease. I have already recommended him to others.

My AC unit went out recently which left our upstairs in the evening miserable (almost 90 degrees). As a parent of two small children, when sleep conditions are too hot for your babies, nobody is sleeping! I called Terrence and he responded same day, and not only got our AC up... Read More and running but also went through the different maintenance practices that would save me money in the future. We were able to replace all of the filters and recharge the unit same day to allow my children to sleep comfortably. Very grateful for Terrence and Air Efficiency HVAC for the fast service. I will be recommending them to everyone.

We felt it was important to leave Terrence a five star review at Air Efficiency! Our cooling system went out! We called Air Efficiency, Terrence was out the next day, and replaced a bad capacitor! We have a cooling again, and we even signed up for a preventative maintenance plan!... Read More Thank you, Air Efficiency and thank you, Terrence!
