So there’s this steam unit heater that won’t put out what it’s supposed to put out. It’s wimpy. The guy with the problem is telling me about it and he’s gesturing like he’s swatting bees. “The fan comes on and I get this hot blast, but then it goes cold,” he said. “It’s like half the coil is hot and the other half is, well, meh.”
“What have you done so far?” I asked.
