Installing second roof A-C

I have a 2009 25' Classic, 30A service, with one 13,500BTU A-C, looking into installing a second 13,500BTU A-C. Anyone done this? What are the pitt falls? Is it worth the cost? Or just change the 13,500 to a 15,000.

I forgot to say. That I know that I will have to go up to a 50a service cord, and install a new C/B for the new A-C.

20 amp service for second AC

Check out my rebuild thread for the '78 Sovereign (below).


I installed a separate 20 amp hookup - more versatile and cost effective than a single 50 amp install.


With the second (20 amp) service I can selectively run the water heater on electric, or the second AC, or an additional heater.


I do not think that you will be satisfied by simply updating to a 15K BTU in place of your current 13.5K model.


Please post pictures of your solution.

Why do you think you need a larger air-conditioner?

With a new 110V 20a for the front A-C. Do you have two power cords?

As a registered engineer, allow me to convince you that it's always cheaper, easier, and more efficient to reduce the heat coming in than it is to put in a larger air-conditioner.

The best bet is to cover the windows on the outside, before the sun gets in.

Check out this awesome idea: http://www.airforums.com/forums/f44/...rs-119109.html
