Lately my oil burner was not igniting and would shut off. We had no hot water. I called fri night and a tech came out within 1/2 hr. He said looks like air is getting in line but not certain. He got it started and I told him it's late. If it happens again I'll call sat. He was not willing to go but I convinced him. Next morning it happened again. He came out and said he was thinking about it all night and zeroed in on the fuel pump and another part.
It worked and I'm grateful for his dedication. BTW, his name is Abel. He cleaned up and made sure there was no dirt or debris when finished. He deserves to be recommended and I will contact corporate on his nice attitude and dedication. Nice work Abel!
