I have been working on re-doing an old guy's house system from propane to heat pump.
He (OF COURSE!!! <g>) has been gabbing with all his neighbors - telling them what I have said. One of them agrees and wants the same thing - so they can get rid of their oil furnace. But . . . . they live in what looks like a mobile home to me. Although it has a peaked roof and no trailer tongue sticking out the front. I just got off the phone with them and what they are describing to me as their furnace sounds like an oil-fired mobile home unit - setting in an open-front hall 'closet', air filter mounted on the front door of the furnace, down-flow with no return ducts.
So my question is: I am installing a residential heat pump condensing unit, matching air handler and evap coil, and electric heat strip for the original customer.
The people across the street now want the same thing. Can I install that same equipment? Even though the oil-to-HP conversion is a mobile home? Do the mobile home specific regulations only apply to fossil-fueled heating systems? Or to heat pumps too?
