Best Solar Panel Cleaning in Phoenix AZ

Today we had our AC serviced (routine) and I must say I was very impressed by the tech, Tommy! When he arrived at my home, I explained that my 10 month old granddaughter was with me. He said hi to her and got to work. My granddaughter eventually fell asleep while he worked outside. When Tommy was done, he gently knocked on the door. As I opened it, he said I didn't know if she was awake or sleeping. I was so grateful for his consideration and kindness not to mention the thorough and timely job he did!
