Legacy Cruisair & Dometic Expertise

Many vessels are still equipped with older, battle-tested Cruisair systems. These units are the definition of 'built to last,' but even the most reliable gear needs a skilled hand. We're not just parts-swappers; we're seasoned technicians who understand the nuances of these legacy systems. From the classic SMX controls to the robust Emerald series, we have the diagnostic experience to keep your vintage system humming.

Don't let another shop tell you it's time for a costly replacement without a proper diagnosis. We have the know-how to source hard-to-find parts and perform repairs that other companies won't touch.

Deep System Knowledge

We troubleshoot refrigerant issues, electrical faults, and control board failures on systems that have been navigating the waters for decades. We respect the craftsmanship of these older units and strive to extend their service life.

Frequently Asked Questions

My older Cruisair system is acting up. Can you still fix it?
Absolutely. We're old salts when it comes to marine systems. We have deep expertise in legacy Cruisair and Dometic units, including the Emerald series. We can diagnose and repair most issues to get your climate control back on track, whether it's a simple fix or something requiring a bit more time on the hard.
What is a Cruisair Carry-On unit?
The Cruisair Carry-On is a portable, self-contained air conditioner perfect for smaller vessels or as a temporary solution during a turnaround day. It's a 7,000 BTU unit that sits on your deck or hatch and provides cooling without a permanent installation. It's a favorite bit of dock talk for its convenience and reliability.
Are you familiar with the Cruisair Emerald (DX) series?
Yes, we have extensive experience with the Cruisair Emerald series of direct expansion (DX) self-contained units. These have been workhorses in the industry for years. We can handle everything from routine maintenance to complex compressor or control board diagnostics.
Do you service Dometic-branded Cruisair systems?
We do. Since Dometic acquired Cruisair, many systems carry the Dometic name but are built on that same reliable Cruisair foundation. Our technicians are trained on both the classic and modern Dometic/Cruisair product lines.
What are common signs my Cruisair A/C needs service?
Common indicators include weak airflow, the unit tripping its breaker, strange noises from the compressor, or failure to cool. Don't be a bilge rat and ignore the signs! Proactive service prevents catastrophic failure when you need your A/C most. Check out our guide on Cruisair error codes for more specific troubleshooting.
