$1427 charge was after senior discount and coupon. Piedmont Gas detected large gas leak under residence concrete slab. Considered an emergency. Needed plumber so called Hiller at 3 pm Fri and tech came at 6 pm. Am well aware of Hiller being notoriously high priced, but also do good work. Because it was the weekend, did not have time to get other multiple estimates and research. Hiller tech began to schedule another contractor to come to jackhammer INSIDE home to find leak and replace lines. What?! No way! This rep had never done work in this large condo development and apparently was unaware of the standard method of dealing with gas leaks here: reroute into the attic (per Piedmont rep). After informing Hiller tech of the reroute he stated that he could do that. Scheduled for next day at 8 am Sat . Tech was polite, personable, professional, and efficient. Began work as scheduled; however job took 10 hours (in miserable conditions)! Estimated at 4 hrs. Yikes! And he was dispatched to another job after this one. There appear to be MANAGEMENT ISSUES here to be addressed: A. Weekdays there are 2 techs to do this type of job but only 1 on weekends. Good grief! How can 1 person do the job of 2 as well over such a long time frame? The human body does not know weekdays from weekends. It is not my business how Hiller conducts its business unless it affects job performance and outcome. Then it is my concern. Hopefully this tech had the skill level and body physiology to do as well alone over 10 hours in extreme heat in an unfinished attic as would have done with 2 techs in half the time. Heat in the attic must have been between 112-120 degrees (unbearable to me) with outdoor temp in mid 80s. What happens when temp is in mid-to-high 90s or 100s? The tech did not complain or make any comments. There are potential medical issues here - dehydration and heat stroke - both serious and affecting performance in anyone. Why not have techs on call for true emergencies on weekends rather than fully staff. Maybe get cooling fans (regular wouldn't help) or cooling vest or cooling scarfs etc. Spend on critical employee safety and performance and cut on advertising - (enough is enough already for adv). B. Need training for Hiller techs or review for how to deal with residences on concrete slabs with pipes under slab. Review ALL options before bringing out the jackhammers which are a near traumatic solution for some people like the elderly, those with respiratory issues, the handicapped or disabled, those with stress issues, those with pets, etc. Would hire this Hiller tech independently anytime, but doubt I would call Hiller again, depending on job- at least not until Hiller recognizes weekend techs more and provides for health hazards. "Happy . . . . . .. . "? The Hiller tech on this job deserves a bonus for hazard heat pay or at least a complimentary lunch out for recognition and appreciation as well as other techs who have worked in such extreme heat long hours.
