Had a pleasant experience in dealing with Cool Air USA. I called for service at 8:20 in the morning and by 10:20 a Technician had arrived at my house. I dealt with Technician Ilan Mazatrim, who thoroughly diagnosed my A/C and provided several alternatives to fix the problem. What I liked about Tech Ilan Mazatrim was his attention to detail in explaining viable solutions. Since my A/C unit was over 10 years old, I decided to replace it. Tech Ilan Mazatrim helped me negotiate an excellent price which was over $1,000.00 below competitors. I was very pleased with professional results.
