Marine Climate Control Systems

Onboard climate control and water systems play a critical role in comfort and reliability. Over time, these systems require adjustment, upgrades, and component replacement to continue performing as intended. When issues arise, they rarely improve on their own—they escalate.

At HarbourFront Marine, we service and support a wide range of marine HVAC systems and their supporting water systems, including Marine Air Systems & Dometic. From diagnosing faults and interpreting control panel error codes to adjusting system programming and restoring proper operation, we focus on resolving issues at their source.

We service and replace aging air conditioning units, upgrade outdated control panels, and repair or replace critical components including relays, seawater pumps, hoses, and sea strainers. Because these systems rely on consistent water flow and properly functioning controls, even minor issues can quickly affect overall performance.

Service Areas:

We proudly service marinas along Lake Ontario, from Hamilton to Whitby, as well as Lake Simcoe, providing both on-site and mobile support tailored to the needs of each vessel and owner.

Don’t wait for a failure to disrupt your time on the water. HarbourFront Marine delivers the experience and technical capability to complete the work properly—so your systems are ready when you need them.
