Called and was able to get an inspection the following day. We got a proposal quickly and all of our questions were answered. The process was so smooth and quick with great service all around. Installation went great. Techs were professional and took every measure to keep our house tidy and clean up after. Highly recommend! Keith Richards2025-06-09Trustindex verifies that the original source of the review is Google. Contacted Earth Air Systems to perform a pre-summer inspection of the heat pump they installed last year. They showed up as scheduled, inspected and cleaned the outside and inside sections of the unit. The lead technician, Daniel, did a good job communicating their findings and gave me some operational pointers. Very happy with Earth Air Systems. Brian Brown2025-04-24Trustindex verifies that the original source of the review is Google. Great job! Dr. Leah Stephens2025-04-10Trustindex verifies that the original source of the review is Google. Daniel and Santiago were great!!! Would highly recommend. They came out and knew what they were doing and did a great job. Kelsi Walts2025-02-06Trustindex verifies that the original source of the review is Google. My experience with this company was exceptional. Remington answered the phone on Saturday night and had his tech out Sunday morning. His tech Daniel was professional and knowledgeable. The part my heater needed was not readily available and Remington worked to find it to take care of us as soon as possible. Highly recommend! Spencer Lenzie2025-01-21Trustindex verifies that the original source of the review is Google. Working with Earth Air Systems was great. Remington was super communicative throughout the process and responded to texts and phone calls promptly. He worked with me on price to find a central system that was within my budget. His employees worked for two days straight installing the unit and new ducting. They were super friendly and took good care of my property, paying attention to cosmetic details and leaving my place clean. There were a couple small follow up issues I had and Remington showed up and took care of those promptly. Would definitely recommend to friends looking for an HVAC company! Jessica Hardesty2024-12-22Trustindex verifies that the original source of the review is Google. Remington and team have been exceptional to work with. They installed my HVAC system recently, and they went above and beyond to ensure that it was done correctly. They checked on me afterwards and plan to make some minor adjustments. Very responsive, professional, punctual and have taken the extra step to check out my system as I was buying my new house. I can't recommend them enough. Ian Reynolds2024-12-13Trustindex verifies that the original source of the review is Google. In June of 2024 I purchased a home in Campo, CA. As part of my mortgage agreement, the house needed to be outfitted with a designated heating and cooling system as the previous owners were utilizing a wood stove and a window A/C unit. The previous owners selected Earth Air Systems to install mini split heat pumps. Upon completing some work on the interior of my home, I noticed the splits were not functioning correctly. I contacted my realtor, who contacted Remington of Earth Air Systems, and he made the time to personally come out and inspect the units. In the following months, we realized that the company utilized to purchase these mini splits, Gree, did not provide enough information to the technician or myself regarding their products. While mini splits typically have an interior filter, some versions of Gree mini splits do not, and we were both very confused to say the least until independently discovering this about these units. Gree was absolutely no help at all and did not communicate with Remington, Earth Air Systems, or myself, but the entire time Remington assisted me through the process.. After coming out independently to inspect the units, Remington quickly scheduled that one of my units be replaced, and the other serviced within a week of me contacting him during the hottest part of the summer. As issues persisted, Remington went so far as to pay to replace the filters and send another technician out to service the units again, explain proper maintenance to me, and reassure me that the units were running efficiently and effectively. I was incredibly happy with the resulting clarity on the products, and the assistance I received. Thank you!

Their team was professional, efficient, and easy to work with. They provided quality HVAC service at a fair price, and I’d highly recommend them to anyone. Cooper Ogle2024-12-05Trustindex verifies that the original source of the review is Google. I had a fantastic experience with Earth Air Systems! Remington and his team truly went above and beyond during the installation of my mini-split system. He took the time to explain my options, ensured the installation was flawless, and even followed up afterward to make sure everything was working perfectly. His attention to detail and dedication to customer satisfaction really impressed me. I highly recommend Earth Air Systems for anyone looking for top-notch HVAC services!
