“My highest recommendations for Devon and the Maritime Air team — thorough, honest, and on time. They explained everything in plain language and didn't push any unnecessary upsells.”

Marine AC Refrigerant Recharge & Leak Detection
Marine AC that's low on refrigerant won't cool — and topping it off without finding the leak is throwing money over the side. We recover, leak-test, repair, evacuate, and recharge to factory spec on every marine refrigerant call.

FAQ
Marine Refrigerant Recharge Questions, Answered
Can you just top off my refrigerant?+
Only after finding and repairing the leak. Topping off without a leak repair is a federal violation and a waste of your money.
Do you still service R-22 systems?+
Yes — many legacy Cruisair units still run R-22. We stock it and can also discuss retrofit or replacement when it makes sense.
What affects refrigerant service cost?+
Refrigerant type and quantity, leak location and accessibility, and whether component replacement is required. We quote in writing before starting.
