After several calls for emergency service, Joe from Ray O. Cook came out at 8pm tonight and got my AC unit working again. I can't say enough about the effort they took to get someone out to my house. First, there was an actual employee answering the emergency repair line! She was determined to find one of their technicians that would come out. Joe found the issue, showed me a picture of the problem and promptly replaced the bad part. I have cool air again :-)).

We could not have been more pleased with the service we received from the entire team at Ray O Cook! Everyone who worked at our house, from the Estimator to the workers who replaced our entire heating and cooling system, were professionals. They arrived on time, worked throughout an extremely hot day, answered all our questions patiently, and cleaned up the job-site when they'd completed. We wouldn't hesitate to recommend them to any homeowner.

The whole team were just fabulous to my husband and I... We are an elderly couple and I am at very high risk with the coronavirus. Roy Cook staff treated us like family. Our air conditioner went out on one of the hottest days and they brought us to their office and put us in a room the break room all by ourselves so we would not be around other people and bought us dinner . I just can’t say enough for this company. Also Paul I want to thank you for the beautiful basket of cookies they were just absolutely wonderful. Thank you again for giving us such wonderful service. I also want to mention Charles he was such a sweetheart to us and made us so comfortable... We will highly recommend you to all of our friends and family. Thank you for all you did for us..

Recently bought a home in Roseville, love the home but was not thrilled with the outdated thermostat. Family and I were irritated our system had an auto cycler that cycled cold air throughout the day and we could not turn it off. I reached out to The Ray O Cook Heating and Air company online, I was called within minutes and was able to setup an appointment for the following day. I was given a window of 4&6pm, Sonny called me shortly after 4pm to let me know he'd be arriving within 15-20minutes. Sonny was very thorough with his Inspection and diagnostic, he took photos of my HVAC system and explained in detail what was going on with the thermostat. I was already planning on replacing the thermostat but I was pleasantly surprised when Sonny informed me he had thermostats available for installation. I did not feel pressured to make a decision right away which was nice. I got my husband on the phone and discussed wether or not we wanted to buy from a hardware store. We decided to go with Sonny's suggestion. I'm very greatful, it's currently 7pm, Sonny just left and we have 2 new thermostats and NO AUTO AIR CYCLING. I'm very pleased with Sonny and Ray O Cook Air. We will be using them for now on for our HVAC needs.

We were very pleased with the HVAC replacement and insulation services performed by Ray O. Cook. The salesman estimator was excellent. He explained the HVAC installation more thoroughly than the other companies and provided a system that best suited our needs at a very reasonable and fair price. The installers were very professional paying close attention to detail while answering our questions about the install. The install manager who came by to check on the install progress was also very knowledgeable and willing to answer questions. We will definitely recommend Ray O.

Paul, Willie, Rick, and Steve were the team that dismantled our old hvac system and assembled the new one. Each step along the way was thoroughly explained and all our questioned were answered to our satisfaction. Details about air flow exchange and capacity, that were never addressed in the past were outlined during the new equipment install. These guys cleaned as they went and were very mindfull of respecting our house. These guys are the Ray O. Cook reputation, and Ray O. Cook should be proud to have them as employees. I would not hesitate recommending this company to anyone replacing or upgrading their hvac system.

Willie and his team were far and above the most proficient and knowledgeable technicians we've had working on our hvac system. Paul expertly layed out the replacement plan and costs. Willie & Rick arrived on time and dismantled & assembled equipment, cleaning up as they went. Steve Brown spent two days doing airflow checks and insuring vents were properly sealed. All of the team answered our questions and kept us informed of each aspect of the dismantle and new equipment install...even to downloading the thermostat phone app and syncing with our home wireless system. Without a doubt, this team has the work ethic and customer service approach Ray O. Cook should be proud of. The reputation of any company comes from its employees and this team showed they have what it takes for 5 star service! I would definately refer Ray O. Cook Heating & Air to anyone looking to replace or upgrade their hvac system.

I wanted to take a moment and recognize the excellent installation work of Willie Daffern (lead) and team They arrived promptly at the appointed time, described the process, timeline and estimated time of completion. They respected the interim of our home wearing their booties at all times, ringing the doorbell when entering as well as making suggestions on other improvements to consider. The installation was for a HVAC unit on pad at back of residence next to the pool. The installation was completed on the 20th at my residence in Rocklin. Please consider me for a reference if needed.

This is our second very positive experience using the Ray O. Cook to completely replace the HEATING & Air Conditioning System in one our properties. The preplanning and needs evaluation by Paul M. was very helpful and complete. The resulting quote was detailed, very competitive and combined with our past very positive experience with the Ray O. Cook Company made our choice very easy. The installation team, Willie and Jose, did a fantastic job both inside and outside our home, this in particular since we had the most miserable weather. The team got extra points from my wife the way they left the job site, very clean! Based on the experience described above I highly recommend the Ray O. Cook Company!

We had the unfortunate experience of our heater going out this winter. We called Ray O. Cook Heating & Air. Their service from start to finish was amazing. Each and every employee is efficient, courteous and knowledgeable. Install Tech Willie Daffern and his team came in to replace our heat/AC unit. Willie thoroughly explained every step of the process so that we understood what was being done and why. Great care was taken in keeping the job site clean. The long and the short of it is, if you need any work or replacement done on your heating/AC unit, this is the company to choose. Thank you Ray O. Cook and team!!!

Willie, Jose, and Kevin did outstanding jobs installing my new HVAC system. Truly professional, polite, and careful crew. I could not be more happy with my new system or the way it was installed. The crew went the extra mile when they found they had to rebuild the base for the new system. The original new home install was poorly done and did not support the old system well and spilled water onto the ceiling area. The Ray O. Cook crew took all the old material out a completely rebuilt the base support for the new system. Great job including Paul who was my first contact with Ray O. Cook. A pleasure doing business with this group. David Cade

I selected Ray O Cook based on the recommendation of a neighbor who had their HVAC system replaced by Cook. Willie and his team arrived on schedule and completed the entire replacement of our system within the day. They were real pros, everything went like clockwork and when the job was finished, Willie carefully went over the entire system, explaining all pertinent equipment operation and all the necessary paperwork. The work site was cleaner than when they arrived and the system works perfectly. A big five stars for Ray O Cook and the craftspeople they employ. This company is the real deal.
