I am having an HVAC upgrade done soon. My current electric forced air furnace is circa 1979. I am having a heat pump/air handler unit installed next month, and I am trying to save money by performing my own electrical work to install a service disconnect to the outside heat pump unit. It will be just on the outside wall adjacent to the existing furnace in the garage. The heat pump will require 40 amp service, so I had planned on running some 6/3 romex from the main breaker panel to the new service disconnect. the main panel is on the opposite wall of the garage (of course), and the walls are finished so this would require a 40 foot run of conduit to the location of the outside heat pump disconnect panel.
The existing furnace has two separate 60 amp circuits servicing what I am assuming are the fan and the heating elements. There are also two 60 amp breakers on the furnace panel functioning as the service disconnects. I think the new air handler unit will likely only take 40 amp service.
I was wondering if I could just "re-route" one of the 60 amp disconnects to make a short run (probably 6-8 feet max) for the outside disconnect panel for the heat pump (which only needs a 40 amp service). disclaimer: I'm a relative novice to electrical DIY, so I apologize if my terminology is incorrect. I've done my share of rewiring for outlets, lighting, and even a clothes dryer but nothing like this.
any input and guidance would be appreciated!
thanks,
Brandon
