I haven't worked on a furnace for over 20 years.
I'd do a little more research. Start by checking and see if the breaker that powers the circuit that feeds is a 2 pole breaker.
Or a small transformer could be used feed the fan motor or furnace.
Wrong, Wrong, Wrong.
Did you not do any research?
OP SAYs they have a "GAS PACK" furnace/AC unit which sits OUTDOORS.
This is not a standard gas furnace that sits in your basement that you are thinking of.
It is also NOT A HEAT PUMP although they use a similar style box and ductwork.
A gas pack system is a all in one Gas furnace with Central A/C all in one box that lives totally out side.
Since the built in A/C would need to have 240V, it stands to reason the the BLOWER MOTOR WILL ALSO BE 240V!
Some posts up I posted a photo of what they look like AND a link to the installation manual.. There is no mention of a blower motor on the one I posted using 120V even for the smallest unit they build..
These units are typically used for industrial types of applications and are designed for 208/240V, will not function with 120V. Many times you will find these types in use in small retail shops sitting at the side of the building or even on the roof..
These all in ones may not be popular in homes in all areas but obviously the OP HAS one of these..
So, YES the OP NEEDS a gen that provides not only 120V BUT ALSO 240V if they wish to run their gas furnace from a gen.
Besides, OP just said that their HVAC person (HEATING AND A/C person) has stated they need 240V.. While I am sure there are some HVAC folks not as bright as a light bulb, I suspect that the OPs is knowledgeable enough to figure out the difference between 120 and 240 is all about..
