When one leak turns into several...
This Frigibar condensing unit came in with multiple refrigerant leaks throughout the original stainless steel braided line set. After evaluating the system, the best long-term solution was to replace the condensing unit and remove as much of the problematic stainless line as possible.
We cut the existing line set back to sound tubing, replaced it with copper, pressure tested the repair, evacuated the system, and commissioned the new condensing unit.
Sometimes replacing a component isn't enough—the reliability of the entire refrigeration circuit has to be considered. Addressing the root cause helps prevent repeat failures and gives the customer a system they can depend on.

A clean installation is about more than appearance—it's about long-term reliability and serviceability.
This self-contained marine A/C system was upgraded by removing the original Dometic unit and installing a new CTM self-contained system. During every replacement, our goal is to leave the installation better than we found it, with attention to proper routing, secure wiring, and components that are accessible for future service.
Quality workmanship today helps reduce problems tomorrow.

When one leak turns into two...
This Frigibar 12V refrigeration system came in with a refrigerant leak in the original stainless steel flex line set.
After making the initial repair, we pressure tested the system and discovered a second leak further down the same line set. Rather than continue chasing multiple failures in aging tubing, we discussed the options with the owner and decided the best long-term solution was to replace the entire line set.
The connection at the box was located, the original line set was removed, and new copper tubing was installed from end to end. Once complete, the system was pressure tested, evacuated, charged, and returned to service.
Sometimes the most reliable repair isn't fixing the leak you found—it's addressing the underlying problem before it becomes another service call.

Mezzanine A/C Replacement – Viking 70
This Viking 70 came in with a failed condenser coil on the mezzanine air conditioning system.
To ensure a reliable repair, we removed the existing equipment, flushed the refrigerant lineset, and installed updated Dometic equipment throughout the system.
A proper replacement is more than simply swapping components. Flushing the lineset and preparing the system correctly helps protect the new equipment from contamination and gives the new installation the best opportunity for long-term reliability.
The finished installation provides improved serviceability, clean routing of refrigerant and condensate lines, and dependable cooling for the mezzanine area.
Quality installations today help prevent problems tomorrow.

Seawater Pump Replacement & Serviceability Upgrade
Customer reported excessive noise coming from the seawater pump. After inspection, we found the pump was beginning to fail and recommended replacement before it caused an unexpected loss of cooling.
While replacing the pump, we also took the opportunity to improve future serviceability by replacing the existing coupling with a union connection. This small change allows for easier pump removal and maintenance down the road, reducing labor time and making future repairs more straightforward.
Sometimes the biggest improvements aren't the most visible ones. Reliable cooling starts with dependable seawater flow, and thoughtful installation details can save significant time and expense in the future.

What a Dirty Air Filter Can Lead To
These air filters were heavily restricted with dust and debris, reducing airflow throughout the system.
When airflow is restricted, the problem doesn't stop at the filter. Over time, dirt and contaminants make their way deeper into the air handler and begin accumulating on the blower wheel.
In this case, the blower wheel had become heavily coated, reducing its ability to move air efficiently through the evaporator coil.
The result can be: • Reduced cooling performance • Increased system run time • Evaporator freeze-ups • Higher electrical consumption • Premature wear on system components
As part of this service, the blower wheel was thoroughly cleaned and airflow was restored.
Routine maintenance is one of the most cost-effective ways to keep marine A/C systems operating efficiently and avoid larger repairs down the road.

Flybridge Freezer Leak Repair & System Rework
Customer reported the flybridge freezer was no longer maintaining temperature.
During diagnostics, we found multiple refrigerant leaks around the expansion valve assembly. Over time, several repair fittings had been added, creating additional potential leak points and making future service more difficult.
Rather than continue patching the existing assembly, we removed the unnecessary fittings and fabricated a new valve assembly with fewer connections and a cleaner layout. The assembly was then insulated and reinstalled.
Reducing the number of joints in a refrigeration system not only helps eliminate current leaks but also improves long-term reliability.
Sometimes the best repair isn't adding another fitting—it's removing the ones that shouldn't be there.

Proper airflow starts with proper duct design.
Follow-up from last week’s 42’ HCB DC air conditioning replacement.
Along with replacing the failed unit, we redesigned the airflow distribution by fabricating a custom plenum box to better manage duct routing and improve air delivery throughout the cabin.
We also cleaned up wiring connections, remounted components properly, and improved overall service access to increase long-term reliability and future serviceability.
Small installation details make a big difference in how these systems perform over time.

When a DC air conditioning system stops working, proper diagnosis comes before replacement.
This 42’ HCB had a DC air conditioning unit that was not operating. After removing the unit, we completed a full bench test to evaluate system condition and determine whether repair or replacement made the most sense for the customer.
During inspection we also identified several installation concerns, including wiring issues and limited service access that would have affected long-term reliability.
Once testing confirmed the extent of the problems, the customer elected to replace the unit rather than continue investing in repairs.
Taking the time to properly diagnose and bench test equipment helps ensure customers can make informed decisions instead of guessing at the next step.
Follow-up photos of the new installation and airflow improvements coming next.

Chilled Water Loop Leak — Main Branch Repair
Customer reported their freshwater pump cycling unexpectedly and suspected water loss from the chilled water loop.
Inspection led us to a ruptured section of insulated hose located in a main branch of the chilled water system.
We removed the damaged section, installed a proper repair coupling, and restored the loop the same day.
Leaks in a main branch can affect system stability across multiple air handlers and introduce air into the loop if left unresolved. Catching and repairing issues like this early helps prevent larger performance problems down the line.
