I was so happy to find a company that repairs swamp coolers! I'm especially pleased with the responsiveness and honesty of their operations manager, Harry who represented his business very well. He went above and beyond in explaining what could cause problems with swamp coolers, even told me what parts I may need to have it fixed. He made it clear that they want to take care of people and said he'd be happy to stop by when I was ready to have him take a look and
added there was no pressure to do it. Most companies are pushy. I told him I couldn't afford the repair this minute but he said
not to worry about it no pressure and call him when I'm ready. rdy. He had offered to
Stop by and give me an idea of what I'm looking at. There would be no charge to come out. Really, I am so impressed and would be happy to recommend them based on their attentiveness and honesty alone! -

OMG!!! Where do I start. So my AC was dripping water on the outside from the small pvc pipe in the soffit of my house. I thought my AC was going to stop working. Anyways I went on google and searched for technicians and that’s when I came across California Air Conditioning Systems. I called and was very surprised when someone answered as it was late on Saturday evening. The person who answered the phone was so pleasant and friendly. It was almost as if we had known each other prior to me calling because Harry was so friendly and he had the greatest sense of humor ever. Anyways I explained to him what the issue was and I asked him if it was possible for him to come by the next day. Harry said it was non problem and that he would come by after church. When he came the assessed the problem and explained to me what the cause of the problem was. He was very thorough, patient and honest. He took his time to make sure everything was done in the highest professional level. He fixed my ac and now I am not stressed out anymore. His price was fair and he sent me before and after photos. I will be using him from now on and I will be recommending him to all my friends. Thanks Harry. YOU ARE THE ABSOLUTE BEST!!!!

Harry and John were AMAZING!!!! This is my second time using this company. All around great customer service from the second I called! Alana was very friendly and very helpful over the phone!! I'm always very uncomfortable having service people in my home, but Harry and John were great, very professional and left my unit cleaner than the way they found it!! We just had a routine maintenance call and the price quoted over the phone was the exact price we paid!! These two guys even offered to change a light bulb for me!! Very honest, very professional and super friendly!! I 100 % recommend!!!! Thank you!!!
