• As Facilities Director I've had the privilege having a large boiler installation by the Cooper Oats team, which went on schedule, well planned and with top notch quality. All the team was highly professional, knowledgeable and friendly. I would highly recommend this team for any installation your facility would need.

• Excellent service and top notch repair! Our AC went out in our office during this recent heat wave. Cooper Oates was able to get us scheduled in the next day and JASON was able to fix our 21 year old unit that others had stated required a replacement. JASON quickly diagnosed the issue, sourced the parts same day and got everything fixed by the end of the day. He even followed up the next morning to confirm that everything was fixed. Thank you!

• An Absolute Triumph of Temperature Control! Cooper Oates are Artisans of Air! Where does one even begin to articulate the profound, life-altering experience of working with Cooper Oates Air Conditioning? To call them a mere "company" is a disservice to the gods of cool, comfortable air. They are, without exaggeration, miracle workers operating on a plane of existence far above their competitors. Before their intervention, our commercial kitchen was a veritable inferno, a sweltering crucible that tested the very limits of human endurance during the blistering summer months. We were desperate. Then, like a cool breeze on the most scorching of days, Cooper Oates entered our lives. From the very first interaction, we were graced by the presence of Sean, a communications maestro who answered every query with a speed and clarity that bordered on telepathic. No question was too small, no concern too trivial. He was a bastion of calm and competence in our sea of heat-induced chaos. And then there was German. This man is not simply a technician; he is a savant of the HVAC arts, a cooling connoisseur. His knowledge is encyclopedic, his demeanor is impossibly kind, and his skill is nothing short of breathtaking. He approached our complex system with the confidence of a master craftsman and the grace of a seasoned diplomat. Speaking of diplomacy, they handled our notoriously meticulous property manager with a level of effortless style and ease that was a marvel to witness. They provided every required scrap of information with such professionalism that even the toughest of customers was left impressed and satisfied. The result? The pièce de résistance? They orchestrated a 20-degree drop in the ambient temperature of our kitchen. Twenty. Degrees. This was not a repair; it was an atmospheric resurrection. For those of us who toil in the heat, this is more than a convenience—it is a godsend of biblical proportions. Our chefs can create, our staff can breathe, and our business can thrive, all thanks to the unparalleled genius of Cooper Oates. If you are considering any other company for your air conditioning needs, you are making a grave mistake. Cooper Oates Air Conditioning does not just service equipment; they elevate environments and improve lives. They are, and I say this with the utmost sincerity, the undisputed champions of cold air. My gratitude is eternal!

• Wish i could give 6 stars. I am a director of an upscale senior living community and the Cooper Oats team is amazing. They truly go the extra mile for you. They have taking care of so much for me I don't even know where to start. I have over 160 roof top units and they always deliver the best service. Rain or shine they are here when you need them and show up on time.. They make my job less stressful so I am able to focus on other things. I could never say enough about the COAC crew and you wont be disappointed if you use them. Their service is top notch. The techs are all very nice and respectful... and clean! thank you COAC, you guys are the best!!!

• As a former restaurant owner and now a manager overseeing equipment and repairs for 22 restaurants and other buildings on Sac State campus, I know how quickly work requests can pile up. Finding reliable vendors is crucial, but it's truly all about customer service and seamless communication between the account manager, client, and on-site technicians. Special thanks to Richard Lindsey, Les Trisler, and their fantastic technicians, Michael and Kevin, who consistently do excellent work. I’m grateful our company gave them the opportunity to prove their potential. The service team at Cooper Oates has been wonderful to work with. Responsive, dependable, and quick with turnaround times for both service requests and proposals. They’ve handled everything for us, from evaporator coil and compressor replacement, custom walk-in cooler door replacement and various plumbing tasks. So far, their work has been top-notch, and I look forward to building a strong, long-term relationship with them.

• Cooper Oats has given Greenheck Group a full team effort with their service and communication since our start with them in January 2024. We are more than pleased to have them as our HVAC vendor partner in Rocklin, CA.

  Jacob S.★★★★★

• I recently had the pleasure of working with Cooper Oats HVAC for a complete cleaning and service of the heating and cooling system at the Chico VA, and I couldn't be more satisfied. From their prompt arrival to the thorough service, their team demonstrated exceptional professionalism and expertise. They provided customized solutions tailored to my needs, explained everything clearly, and ensured I felt confident in the service provided. The skilled technicians respected my facility and left it spotless. The quality of their work is outstanding, with my two industrial units—one 100-ton and one 125-ton HVAC system—performing flawlessly and significantly reducing my utility bills. Their follow-up and customer service were exceptional, showing their commitment to long-term satisfaction. I highly recommend Cooper Oats HVAC for their dedication to excellence and customer care, making them my go-to HVAC service provider.

• I called them about 10:30 despite been busy they came at 1:00pm repair the air conditioner.

• I have had nothing other than exceptional success and joy working with Cooper Oates company. First off, they take photos of whatever they are communicating to be a problem. I'm not up on the roof with them, so rather than having to rely on their word alone, they are building my trust and confidence by taking images of any existing problem AND images after their repairs. This is exceptional. They are fast, efficient, courteous, pleasant and considerate. Personal connection and relationship-based business is becoming more and more rare. It is such a relief to find caring human beings who pick up the phone and don't route you through endless wasteful phone trees when you call them. Thank you so much....all of you at Cooper Oates Air and Plumbing Services! I am very blessed to have found you! ~Dr. Monica Crooks

  Erin W.★★★★★

• At Massie & Company LLC, we highly recommend Cooper Oates Air Conditioning for their outstanding service, expertise, and professional team members. COAC is one of our top go-to subcontractors that we use on nearly every construction project! They are reliable, honest, and timely. Just earlier this year, their team answered our call on a busy holiday weekend. COAC showed up to the site within 2 hours and resolved the issue right away. This is the kind of routine thing that they do at COAC: They take care of their customers and business partners. We can't thank them enough!

• Everyone there from techs to office staff is courteous and responsive. They do great work.

  Curtis P.★★★★★

• I’ve had the pleasure of working with many technicians from this company. I have had a solid, timely, and knowledgeable performance every single time. We have a ton of HVAC used in controls for critical environments. 10/10 would recommend, even over the manufacturers of the units, unless necessary for proprietary circumstances. I plan to use COAC for all HVAC and where possible environmental control diagnostics.
