Hello Terry... Camper A/C's are not rechargeable. They are a sealed system from the manufacturer and although people do find someone to recharge them they will definitely leak back down... Generally by the next season. For this reason we as a service center never offer that option because we have to stand behind and warranty the work we perform. We do do A/C repairs as necessary other than the freon

Wash your roof with mild detergent and soft brush. Apply a UV protectant afterwards. Check for cracks in caulking. If necessary clean debris and dirt from old sealant and apply dicor lap sealant over old sealant. This is ok once or so but if it is in really bad shape it must be peeled up completely and recaulked. Hope this helps. We have everything you'll need in the shop. Thanks for contacting us.
