What's Berthed at Harbortown Marina
Harbortown's mix of large sportfish, cruising trawlers, and refit projects means we see everything from single self-contained Cruisair units to multi-zone chilled-water systems with 4–8 air handlers. We also coordinate HVAC work during yard-side bottom jobs and refits.
Response Time to Harbortown Marina
Typical Harbortown response is 30–60 minutes from our Fort Pierce shop. We work with the Harbortown dockmaster and yard office for access coordination.
What We Do at Harbortown Marina
Multi-zone chilled-water diagnostics
Webasto, Cruisair, and Dometic chiller-loop troubleshooting — flow switches, pump cycling, expansion-tank pressure, and SeaProof line corrosion.
Yard-side AC work during refit
We coordinate with Harbortown's yard crew during haul-outs to perform line replacements, raw-water plumbing, and condenser swaps that aren't practical at the slip.
Cruisair / Dometic R-22 to R-410A conversions
Older Cruisair systems with R-22 charge can be retrofit or replaced with current R-410A equipment. We size, source, and install at the dock.
Sea-water strainer & through-hull service
Cleaning sea strainers, replacing through-hull check valves, and restoring proper raw-water flow through HVAC condensers.
New chiller / air-handler installs
Cruisair, Dometic, Mabru, Webasto — full system design, sizing, and installation for refits and new builds at Harbortown.
