had an emergency in the middle of the night and of all the places that claim to have 24 hr service, Paul was the only one to call me back and was at my house within 1 hour. very professional, explained situation, gave details of his exceeding he was doing, very friendly and reassured that he would be available any time I needed him to come back, advised me that now it's his problem and he will guarantee to get rid of my problem. im a happy customer. thanks Paul.
