moving heater/blower

Our gas heater/blower and AC cooling coil glob is currently in a closet inside our laundry room. I'd like to move it about 4-5 feet to the other side of a wall into the garage. The purpose is to expand the laundry room and to move the noisy blower out of earshot of the family room and TV.
How major an effort would that be? An electrician would have to move the 220V service. A plumber or HVAC person would have to re-route the gas line, the coolant lines from the external AC compressor, and the ventilation ducting. Am I missing anything? Any wild guesses on what I should expect to pay to have this done? I'm in San Diego.
I may do the framing and drywall work to finish off the expanded laundry room myself.
Thanks, Rob (email is bogus - please reply to the group)

You may find you can't do it. Local building codes are rather particular about such things.

Contact a couple licensed HVAC contractors and get quotes from them. Garage - an area that stores flamable materials, vehicles with CO exhaust, etc. Most applications require that a fire-proof room be built to enclose the furnace, as well as 2 fresh-air (combustion) inlets into the room. Most garages are counted as "un-conditioned" space, so freezing condition could exist during the heating season = bad idea for a 90% (+) furnace that produces condensate. If the unit is not a 90% (+) then you have a flue to run through the garage roof, not to mention extending the ductwork, insulating it as it passes through the closet wall into the garage. This can become a very involved project, you may as well think about purchasing a new furnace if you're going through all the expense to relocate it...
