Moe Shanableh came on a Friday night at short notice to examine our central heater that had stopped operating during the day. He quickly identified the problem, had the parts on hand to fix it, and just as quickly had it repaired. He was careful to observe the heater's operation and did not leave until he was satisfied with the repair. Moe has visited our house for furnace inspections and some repair on previous occasions: he is always polite, maintains a very clean work area, and explains technical problems and his repairs in a very clear manner (ditto answering questions). Very competent and pleasant technician.
