Alvin did a fantastic job of diagnosing and correcting the problem with my Fujitsu mini-split wall-mounted HVAC unit. I have 5 of these units in a single rental property, and it was very important to restore the problem unit to full usage for the new family who just arrived to rent it as a vacation rental. Timeliness was critical, and Alvin came through with flying colors. Such a great job that he did.
Thank you very much, Bill Howe
