I’ve had different companies coming out every year since I’ve lived here for the annual cleaning. Finally someone that spent some actual, real time with the unit, and who took the time to explain things as well as show me pictures. Josh was the best! As are the girls in the office. Would give a 10 if I could!
Josh from comfort zone was polite and friendly. He was very professional and informative. I will definitely use comfort zone again.
