Harry and his team were super friendly, efficient, and got the job done extremely quickly when my AC unit completely died in the middle of summer. They were very professional and helped coordinate all the details (crane rental, hoa approval) to get my new AC up and running as quickly as possible. Highly recommend

Ok this is for all of you who live in Los Angeles. I just had the best experience with Harry from California Airconditioning services. Wait you say its Sunday . Yep twenty four hours a day and seven days a week. He was honest fixed the problem right away and pointed out a couple of things that I could fix myself . After trying about twenty companies that advertise 24 /7 emergancy service and most of them saying "we can set an appt up during the week, the 24/7 means we answer the phones 24/7" . Actually they were all call services and not the actual companies. Harry was personable and said " I just got back from a job and want to eat lunch, but I will come as soon as I am done in about an hour. AN hour and ten minutes later He was here. . Fixed the problem 310-530-0504

Response from California Air Conditioning Systems, Inc.

"We at California Air understand that a proper diagnosis of a problem is essential to its proper repair. We are up front about our diagnosis costs, which represent a professional and expert opinion. Our professional, experienced technicians spend time to thoroughly diagnosis a problem so that the right fix can be determined. That is a valuable service we provide. The cost of the repair is separate from the diagnosis fee."

I called this company and spoke to Harry after my brother hired a handyman to originally to replace a wall heater and venting system.       According to Harry, the handyman did a horrible and dangerous job so I am happy that Harry and his team fixed the problem.     I would  hire this company again.    If I had done this right the first time and not use that darn HANDYMAN, I wouldn't have spent so much money if I had just called California Air in the first place!     One thing I learned about all this....HIRE SOMEONE WHO KNOWS WHAT THEY ARE DOING!

Harry came out for a diagnostic on our air conditioning.  He quickly alerted me to the main problem at hand, which was a dangerous freon leak inside our house.  There was some shabby repair work done before we purchased our home (a leak in the copper tubing leading to the cooling coils was sealed up...with thick black tape...).  The black tape was saturated, showing that freon was seeping through and escaping into the air.
After the diagnosis was done, Harry contacted me via email not an hour later with an estimate on the repairs.
The price for the repairs included cutting the leaky pipes out and replacing them, repiping the discharge line, pressure testing the system with nitrogen, pulled vacuum and charging unit with R22 gas, and dialing in the amp draw to the name plate ratings.
The next day, a repair tech named Seto came and worked on the system.  He did everything stated on the estimate and thoroughly made sure that there were no leaks after testing the unit with nitrogen gas.
In the end, I was EXTREMELY HAPPY with the work that California Air Conditioning Systems performed.  I will definitely be spreading the word around to friends, family, and neighbors.
