Mounting one of our A/C systems in your camper, RV, semi truck, overlander or custom application leaves your roof aesthetically pleasing, compliant with HOA or open to an entire array of solar panels.

A full roof of solar means you can have endless A/C at your disposal as the wattage requirement of our A/C system would be offset by the output of the solar system. Net 0 comfort.

Our A/C systems are designed using the highest quality components we can source. UndermountAC is in touch with the community and we are constantly innovating and improving our products.
