Dear Mr. Stewart:

During the recent hot spell our air conditioning unit was not doing much of anything. Being a Comfort Club Member I called your company for help. Don (last name ?) responded. He had serviced this unit last year as well and had given me notice that things were not really good! His April 29th visit (this year) confirmed that. Don nicely offered the choices to be made and set in motion the ultimate purchase of a Bryant 187B air conditioner. Don's manner of discussing options is commendable and confidence building. Thanks Don.

Kevin and Gus installed the unit Friday and it was a great day in our households Cool air! It's always a pleasure to see people work who know what they are doing, and Mr. Stewart you should be proud to have these folks in your company. They were most cordial, glad to answer questions and good workers. Thanks Kevin and Gus.

A pleased customer,
