Sam was very professional in carrying out his tasks. I would recommend his business.
I cannot thank Sam enough for his prompt reply. Our air con decided to pack it in when we were experiencing 42deg temps. He came the morning we phoned and all was fixed in 2 days due to getting the right parts. Thanks so much Sam Elizabeth and Stuart
