Question:
Is my Coleman Mach AC compatible with any of your rooftop ACs. Model 48254a866 I think mine is 15k btu, but Id probably be fine with 13,5k btu.

Hi Charles,
If you're wanting to replace just your Coleman rooftop air conditioner unit and keep the air distribution box and thermostat you currently have then I recommend going with a Furrion AC unit like the # FR42PV (white) or # FR32PV (black). Your current system has a 15,000btu rating so you'd want to stay with that for the new unit as well. These replacements will come with an adapter cable to plug into your Coleman controller for an easy installation.
