Im a residential builder and this is the first time Ive ever had this happen, my hvac guy (herb) probly 60 yrs old (husband and father of 2). i came around the corner to find him face down on the side of the house, ran to him and rolled him over to find no pulse or breath, i called 911 while doing C.P.R for what seemed like 30/min before they got to us and took over, unfortunately after getting him to gwinnette medical center he passed away, could'nt sleep last night as the days event kept playing over and over and wondering if i had gotten to him a-little sooner. GOOD MAN WAS LOST (R.I.P)
