Marine Chiller System Service & Repair

Chilled-water yachts demand a different skill set than self-contained units — chillers, fan-coil units, seawater loops, glycol mix, and zone controls all have to work together. Maritime Air Co. services chilled-water HVAC from 60,000 to 240,000 BTU on Treasure Coast vessels.

Working with Devon on my HVAC system was a great experience from start to finish. Honest pricing, clean install, and the system has been running perfectly through Florida summer heat.
