I can't say enough good things about Brooklyn's Best AC. I called them on a Wednesday because all our AC units had been flashing error codes and not turning on during a heat wave. They came out on Thursday to take a look at the problem ; they provide a 4 hour window, but arrived within the first 30 minutes - first good sign. Within 10 minutes the technician had the problem diagnosed and the parts ordered. He said 3-4 day business day turnaround for the parts, but on Monday (1 business day after the first visit) I get a text saying "there's a storm tomorrow, I want to get all the work done today so I'm going to go pick up the parts". One technician arrived soon after and got started, followed by another tech. with the remaining parts. Within an hour the ACs were blasting cold air as if nothing had happened. Huge thanks for going out of your way to get the repair done early and with high quality. Also thank you for observing all COVID-19 prevention guidelines : masks, gloves, etc. I hope I don't need to get other major HVAC repaired any time soon, but if I do, I will be picking Brooklyn's Best
