Came to my condo in Sunny Isles Beach on Friday evening only to find my AC unit not working. Called Cool Air USA Saturday morning at 8 AM and there was a technician at my door within the hour. Before entering unit he put on surgical shoe coverings and proceeded to inspect AC unit. After the brief inspection he explained to me why the AC unit was not working in terms that I understood and gave me a reasonable quote. After accepting he went to work and was done within 2 hours and he left the area cleaner then when he started. I would STRONGLY recommend Cool Air USA to anybody with an HVAC problem. I am only sorry that I did not ask the technician his name so I could personally request him for my next service . An A1 company in my book.
