Does anyone of the Infinity owners have the oil heat option? It seems like
their online tool always combines a heat pump (rather than simple AC) unit
with the oil furnace, making me think it's a heat pump system with oil used
for supplemental heat, something I don't want. We are too used to having
hot air to come out of the vents.
