Our house was on the market, and we had decided not to spend the money upgrading our mechanicals. Fate had a different idea when the water heater went into meltdown. I called Kuhn who sent a repairman over that afternoon. I asked them about a new furnace while they were there. They gave me a great price on both (I checked around) and installed them the next day. The two guys who came over were friendly, professional, and quick, hard workers. I would definitely call them again.
