Technician was very thorough and explained everything to my satisfaction. I always use McCulloch. Wish Guillermo could come out every time. Please give him my regards for a job well done.

Henry found what was wrong with my air conditioner, got it up and running, and explained in clear terms what was needed in order for the unit not to have recurrent problems. I was happy to schedule the repairs he suggested.
