  • What Our Customers Say:

  • "We were glad that we have an annual maintenance contract with Haller for our whole-house generator. When Hurricane Irene came through Sunday, August 28, we lost landline power from 6:30 a.m. to 11:40 p.m. The generator ran the whole 17 hours with no problems, keeping the house cool and lit."
