I have no clue what they did when they came out =)
It was a year ago and we had problems with our air conditioner. Today I was recommending them because of the great service they provided and realized that I didn't write a review last year so I wanted to take the time and do that even though I can't remember what exactly it was that they did. What I DO know is that they came the same day, they were friendly, professional and did not walk away with a million of my hard earned dollars!!! Oh, and they walked us through step by step with explanations. I didn't feel cheated and I felt well informed. Thanks cool touch and just so you know I am sending you a referral!
