My service technicians name is Ronaldo. A complete visual, cleaning, and full maintenance test was performed. I was able to observe the service as it was being done. Ronaldo was polite and professional and explain all of the checks and repairs as they were being preformed. I also had some added parts installed at this time which should help eliminate any build up of mold with that in the AC unit. I am confident that I was in good hands with Ronoldo.
