Called and got same day service. The technician arrived in the window that I was given and diagnosed the issue quickly. No additional costs other than the charge for the visit. Great company that I will surely use in the future. Forgot to ask for a business card but with the internet I guess that is not a big deal. Thanks so much.

My friend, I recommended (Gary Schorr) in Palmdale was very happy with your service as was I. Just wanted to say thank you for your good work and honesty. It’s good to have someone we can trust servicing our central air conditioning and heating. Feel free to have anyone contact me about your service. Thanks,

Hi AD Cooper!I just wanted to dropped this little note of appreciation. I really am enjoying my new Carrier AC unit and my place is now so awesome and cool! I also wanted to say a huge Thanks for the fantastic service that your entire Team displayed. While proving to be challenging to get the new unit in my backyard, Cory and the team of Raphael, Nick and Jason did it and the new unit was safely installed in my backyard! That's awesome team work!!! Thanks so very much for everything. I did enjoy speaking and working with Blanch and Bert too! Nick was the 1st guy that did the evaluation. My thanks to him also.Thanks,

Hi Tom,Thank you for sending Mike over to Dad’s yesterday to repair the air conditioning problem. I appreciate the prompt response to my Dad’s call. Mike found the problem and repaired same under difficult conditions. The attic must have been well over 100 degrees. Thanks again for standing behind your work. You have a great company and great people.

I just wanted to thank A.D. Cooper company and their technicians for their continued prompt and courteous support. I do realize that the recurring problems I am experiencing appear due to equipment design issues, possibly exacerbated by the recent power distribution upgrades performed by Edison, and are largely outside of your control. I do appreciate the excellent and prompt service you have given me as we await a permanent solution. Believe me, I feel terrible each time I have had to call you back, but you have always responded in a way that exceeded expectations.I thank you for your continued efforts! Please let me know if there is anything I can do to facilitate a resolution of the problem with Carrier.Thanks again!

Quick, honest, and compared to the other quote from the previous company, competitive pricing. Signed up for maintenance and will definitely use them for my future replacement.

As a Ph.D. Engineer, I know HVAC systems. These days so much depends on the quality of the installation. The NATE certified tech, Danny, was terrific. I am sure I will be trouble-free for years. Corey and Tom Jr were a pleasure to do business with.

My husband Mike and I would like to commend the technician you sent yesterday to perform routine maintenance on our heating and A/C units. Ralph is a very polite and knowledgeable young man who obviously takes great pride in his work. He arrived on time, well-groomed, relaxed and ready to work. He took care to cover his feet and keep things clean. Ralph communicates very well and let us know what he did and he made some sensible recommendations. Ralph has the maturity of a person many years his senior and you are lucky to have him as your representative. Thank you for sending him our way.

Thanks for your prompt and courteous service. We’re already appreciating how quiet the new unit is. I’m sure our neighbor’s feel the same! Ralph was a pleasure to work with. He was very professional and a great listener! We look forward to continuing our long time relationship with you.

I contacted Cooper Heating & Air Conditioning on Monday, stating that my air was no longer cooling. (We have a contract with them) They scheduled an appt. for the next day. Ralph came early (yea!), looked at our system, found the broken part and had it replaced within one hour. Ralph was very nice to work with. He is knowledgeable and kind. I definitely recommend Cooper Heating and Air and Ralph.

Ronnie from Ad cooper has been great! I've used the company service on two different occasions for repairs and maintenance. Both times they sent Ronnie for the job. I was extremely pleased. He showed up right on time and was extremely professional and courteous. He seemed honest and didn't add any unnecessary repairs like some of the other companies have told me in the past. This is the only company I would use for all my future maintenance or purchase.

Thank you for coming out and getting the AC going during our recent heatwave in October. It was very HOT, and the AC comes in handy! Sandy told me that the tech that came over, Ralph, was very nice and helpful. We appreciate you and your great service! Thankful Again,

I have been dealing with Cooper for several years now and they have always done their best to respond to my concerns. Their follow up calls are as just as professional as their initial installation of our a/c and heat plus other add-ones. Their recent trip to our home concerned a message that popped on our Infinity thermostat indicating an electrical fault. They sent Ralph out the same day I called!!! Right away he started his procedure of checking everything. He found a few minor things that he corrected but the message would not go away. He even went under the house checking wires to the outside unit. He reset the thermostat twice but no change. It was late and he said he would be back tomorrow morning. Later that night I went to check the thermostat one more time and you guessed it, everything was working normal!!! One of the little things he found and fixed must have finally got read by the controller. What a great ending for me!!! I called Cooper the next morning with the good news! Ralph was very happy that the things he did paid off! We will ALWAYS be a Cooper customer! Don't waste your time with anyone else! The Stoddard's in Lakewood

Andrew D. Cooper AC was to be the 2nd estimate I was getting to replace the AC system as I was told by the first company. To my delight, Cooper tech Ron arrived (a little early) and after checking equipment told me it simply needed refrigerant. It was wonderful to find a company whose techs are honest, sincere and trustworthy. I'm staying with A D Cooper and will recommend them with confidence.
Service: Addition of refrigerant

Since I first met the Cooper people at a home show and they installed heating and air conditioning into my 1927 home in Fullerton I have shared my positive personal experiences with them. I recommended them to a neighbor and the next week they were there. Their service contract and maintenance agreement keep my home comfortable when needed. Great people.
