Had to have some electrical work done. I called Ungerman because I have used them in the past. And as usual, they were prompt; in fact the technician was a little early. The office called me to ensure that it was o.k. to arrive a bit ahead of schedule. The young man who arrived was Jerry who was neatly dressed, polite, and got right to work. He was knowledgeable and explained what he was doing. He answered questions about the wiring to my furnace which I was having trouble with. He completed his work in a timely manner and the bill was reasonable for all that he had done. I have found that those companies who hire polite, neatly dressed technicians, and who try to explain things to the customer, are the companies to stick with. Ungerman is that kind of company.
