I called H Jack's Heating on a cold 7 degree Monday morning this past January because our furnace stopped working. A repairmen was at our home within 2 hours of my phone call. After thoroughly inspecting our furnace, he told us it just need cleaning and a new pilot. He gave us a written estimate before he did the work and had the whole job done by lunchtime. They provided great fast service on a cold day when we needed our furnace the most!
