A​re you interested in getting a larger output unit?

Customer: replied 2 months ago.
Maybe
Expert:  Randall replied 2 months ago.

S​ee the attached link for the replacement for this model. It is still a 13.5K unit. You can go to a 15K unit which is about the same, but more money. You may be able to see your old one and get some money back from that. Used A/C units are easy to sell, especially this time of year. http://www.americanrvcompany.com/Dometic-B57915-Brisk-II-RV-Air-Conditioner-13500-BTU-White

Does it come with a new control unit?
Expert:  Randall replied 2 months ago.

A 15K unit is about $200 more in a BriskAir II model and then on either one you have to upgrade the thermostat as well.

Customer: replied 2 months ago.
Ok. I will give it a try. Thanks

You would want one that comes equipped for a Dometic Single Zone thermostat. And you are most welcome! Please tell your friends about our service here at Just Answer. And I would appreciate you taking the time to enter in a Star Rating as that is the only way I get credit for the time spent assisting you on this question. Thanks!
