David is one of the most professional individuals I've had the pleasure of receiving a service from. He was punctual, performed his occupation throughly, explained everything he did while showing me the pictures of the A/C unit, and is very courteous, respectful, and polite. I would highly recommend David to anyone who is having any issues with their A/C unit. His work was nothing short of magnificent. For anyone looking for an A/C technician, ask for David and I'm sure he will fix the issue. David deserves a raise in his salary, not only for his work, but for performing it under the extreme heat of Miami, FL.
