Got home from work at 6:50 pm and my A/C was not working, it was 95 degrees outside and 84 degrees inside my house. I called Cool Air USA and the tech (Leo) arrived by 8 pm. He diagnosed the issue, explained my options, replaced the parts and fixed the A/C by 9:30 pm. No after hours fee, no hidden costs, no hassle. Leo was very professional, he explained everything in easy to understand terms; he followed CDC guidelines and cleaned up when he finished. I am very pleased with Cool Air USA, they're professional and reliable. I will use them again and I highly recommend their service.
