Adding Air Conditioning to Your Morgan 383: Options and Professional Installation
For a classic sailboat like your Morgan 383, adding an air conditioning system can transform your comfort on the water, especially during hot Texas summers. Because your boat does not have a factory-installed unit, a new installation is a project that requires careful planning and professional execution to ensure the system is properly sized, safely installed, and operates efficiently.
At Yes Centers, we specialize in a full range of marine HVAC services, from new installations to repairs and upgrades. We are here to help you understand your options and provide an approximate quotation for your project.
Understanding Your A/C Options
When adding an AC system to your boat, there are typically two main options to consider:
Self-Contained Unit: This is the most common choice for boats of your size. All components—the compressor, evaporator, and condenser—are housed in a single, compact unit that is typically installed under a bunk or in a locker. Self-contained units are simpler to install and are an excellent choice for cooling a single cabin or saloon.
Split System: A split system separates the components, with the compressor located in a machinery space like the lazarette or engine room and the air handler in the living area. This results in much quieter operation inside the cabin, but the installation is more complex as it requires running refrigerant lines between the two units.
Factors That Influence Price
The final cost of your AC installation depends on several key factors, so an in-person consultation is necessary for a precise quote. However, here are the main things that influence the price range:
The Unit: The size of the unit (measured in BTUs) and the manufacturer’s brand will affect the cost. For a boat your size, a 12,000 to 16,000 BTU unit is a common choice.
The Installation: Because your boat lacks an existing AC, the installation will require a complete setup, including:
Installing a new thru-hull and sea strainer for the raw water supply.
Mounting a raw water pump below the waterline.
Running new plumbing and electrical wiring.
Installing new air ducts and vents throughout the cabin.
Professional Installation is Key
A first-time AC installation is a complex job that requires specialized tools and expertise. It involves drilling a new hole in the hull below the waterline, managing high-voltage electrical connections, and handling refrigerants, all of which must be done according to ABYC standards for safety and reliability. Our certified technicians will ensure every component is correctly sized and safely installed.
