Hi all,

I have an old house. I'm looking for a way to tap into, so to speak, the 240V line that is running my central AC.

My panel is fully maxed and subpaneled. There's nothing else to do except replace it when it comes to adding 240V.

I have gas appliances: stove/range, dryer, hot water, steam boiler. Nothing's pulling big on electric. House has been converted 100% to LED lights.

Ideally, what I'd like to do, is have an electrician install a 14-30 line from the existing line that feeds the AC compressor. This appears to have its own individual 50A subpanel in my wall.

I'd like to have the 14-30 wire run to the side of the house so it's easily accessible from the driveway where I park. I would plan on using this outlet in colder months (September through April) when the central AC is not being used. During the summer months, when my car is not driven as much, I will use a 5-20 outlet in my garage or consider "moving" the outlet outside for easier access.

I've included a couple pictures for your review. The quote from multiple electricians has been in the ballpark of $2000-2500. This would be somewhere closer to the $750 range, if possible. I'd then reclaim almost all of it through state incentives.

What is the best way to have this done? I am happy with having some type of transfer switch setup on the outside of the house where the wire feeds into what looks like a breaker for the condenser. I could ask that they replace the AC subpanel with the extra breaker for the EV charger but I think that would be potentially bad, as there would be nothing to stop someone from running all things at once.

Thanks.
