Frequently Asked Questions

Marine AC Repair FAQ

How much does marine AC repair cost in Fort Myers?

Marine AC repair in Fort Myers starts at our $200 minimum service call, which includes diagnostics. Most repairs range from $350–$1,200 depending on the issue. Compressor replacements run $1,800–$3,500. We provide a written estimate before any work begins — no surprises. Call 239-323-9600 for a free phone consultation.

Why is my boat AC not blowing cold air?

The most common causes in Southwest Florida are: (1) Scale buildup in the heat exchanger from warm saltwater — this restricts water flow and kills cooling capacity. (2) Low refrigerant from a leak. (3) Failed seawater pump impeller. (4) Clogged raw water strainer. (5) Faulty thermostat or control board. A professional diagnostic identifies the exact cause before any repair.

Do you offer same-day marine AC repair?

Yes. We carry common parts (impellers, capacitors, thermostats, control boards) on our service vehicles for same-day repairs when possible. For compressor replacements or major component failures, we typically complete repairs within 24–48 hours. Emergency and after-hours service is available at $220/hr. Call 239-323-9600.

What marine AC brands do you repair in Southwest Florida?

We repair all marine AC brands: Dometic (formerly Cruisair), Webasto, Marine Air, Mabru, Flagship, Condaria, Marinaire, Mermaid, and custom installations. Our technicians are factory-trained on Dometic and Webasto systems. We also service legacy systems that other shops won't touch.

How often should I service my boat's air conditioning?

In Southwest Florida's warm saltwater, we recommend service twice per year — spring (before peak heat) and fall (after the season). This includes coil cleaning, descaling, impeller inspection, refrigerant check, and electrical testing. Annual maintenance prevents 73% of AC failures and extends system life by 5–10 years. Our maintenance programs start at $295/visit.

Can you flush my marine AC system?

Yes. AC system flushing is one of our most-requested services. Salt and mineral scale builds up in heat exchangers and seawater lines, reducing cooling efficiency by up to 40%. We use professional-grade descaling solutions and verify flow rates after every flush. Most boats in SWFL need a flush every 6–12 months.

What areas do you serve for marine AC repair?

We provide mobile marine AC repair throughout Southwest Florida: Fort Myers, Cape Coral, Naples, Marco Island, Bonita Springs, Estero, Sanibel, Pine Island, Punta Gorda, Port Charlotte, and Sarasota. We come to your dock, marina, or boatyard. Core service area is Lee and Collier County with no travel surcharge.

Do you install new marine AC systems?

Yes. We design and install complete marine AC systems — self-contained, split, and chilled water configurations. We size systems using BTU calculations based on your vessel's cabin volume, insulation, and window area. Try our free AC System Builder tool at accumarmarine.com/tools/ac-system-builder. Installation includes ducting, seawater plumbing, electrical, and commissioning.
