Cost of AC

[Phasma2128]

I just received a quote to replace two of my three AC units. One is for the bow cabin which is a 6000 unit and the other is a 24000 unit for the salon. $23,000. Unbelievable

I assume they re splits and that includes both air handlers and condensers?

Prices have been spinning out controls over the last few years. I just paid $1900 for Headhunter Mach 5 240v water pump which 4 years ago was $975…. It s nuts.

Went to west marine yeasterday to get 4’ of 5/8 heater hose for my gen along with 7 hose clamps. $100.88 for the lot with the pro discount. Would have been $140 otherwise.

Anyway back to your issue, I wonder if a chiller and 2 air handlers wouldn’t be cheaper. Yes you d have to run insulated hoses but could be worth it. Then when the other 2 or 3 original fail you re half way there and put a second chiller.

To think that 7 years ago I paid about $24k for two 36k chillers and 5 AH!!

from who and what units? 10/2022 (2)9000 ((1)12k (1)24K from Oceanbreeze installed was $30k. Industry is out of control. I will endorse their units but DO NOT LET THEIR CREWS INSTALL!!!!!!

I did single-piece units in each stateroom, and the V-berth also cooled the galley. I did the installs myself, I probably spent less than $15K. Yes I had to work thru all the installation issues, but I learned a lot. I'd be glad to talk thru what I did.

Just installed 16,000btu in Master vented to midship vip and 13,000btu in forward crew quarters vented to forward stateroom bunk room. Went with Webasto Blue Cool Series S and spent just under $5,000, buddy and I did the installation. Purchased through Citimarine. Pulled 2 splits from engine room and an air handler from each stateroom. Put out a YouTube video overviewing the installation of the 16,000 btu unit.

Look at flow marine systems. I’m able to re use my handlers and just replace my compressors on my 38c. Compressors were only about 4200 each for 16k btu units

I have had just the compressors changed for like $1600 each I think. Requiries a guy who can weld/solder or whatever it is called to the original HX chassis. Make a deal with the devil to get ahold of R-22 or use the drop in but why reinvent the wheel when the new wheel won't last long before problems?

I've replaced just the compressor unit as a whole. Screw on the lines, hook up the wiring, evac the system and charge it up. No special tools required except a vacuum pump and a set of gauges.

Retail on new 24k btu DQX condenser with titanium coils is about $6k. 2 12k evaporators about $3k for the pair. Compared to lesser brands I didn't see a big delta in price. Maybe the evil empire isn't so bad.

Service and support from a great vendor I work with often is worth it too.

I am going to do the same. The midcabin AC compressor croaked. It handles not only the mid cabin, but also the V berth. 12000 BTU. Going to get 2 6000 BTU self contained units. about $ 1800 ea from Citimarine. Already had the Freon evacuated from the old unit. Take the old stuff out, put in the new ones, wire up 120VAC and thermostats. Midcabin unit is directly aft of the compressors in the port engine room. A few feet of hose for water supply and return.

The V berth will probably require an additional raw water pump. Still evaluating that. Can use one of the abandoned through hulls originally intended for dumping black water overboard so don't have to drill through the hull.

Will probably do the midcabin yet this summer and the V berth this fall after the boat is hauled.

I used the 230vac - note the seawater pump should be strong enough if you drill out a discharge above the water line near the new A/C unit. If you try to push the water from the units back to the engine room you’ll likely not have enough water flow. I’m running all systems off the original water pump. I spoke with someone on this site who actually put in a manifold near the pump so they could adjust the flow to each unit. They said it works fine.

I wanted to share this link. I keep a R22, 10 pounder on board for use as needed. I have found this vendor to be very reliable and shipping is free. Eventually we may not be able to buy R22 this easily.

Hello Phasma,
I have been in process of replacing ac aboard the Hatt na Mara 56 MY. The first step was to replace the port pump and add a second March TE5.5C-MD, 115/230 for the starboard side. The cost was about $2,200 from Steve at Flagship Marine. That included a thru hull and an 1 1/2 groco strainer. That was a significant amount of work and time to install.
The next step was to remove compressor from generator room under galley that serviced the aft cabin. This unit was not working anymore. There were two air handlers in the bed side tables. The space is very limited. The only self contains that would fit were the FCF Platinum 6k btu 230 R410a - 5011395A. I got two of those from Steve at Flagship. The cost was under 4k and the service is outstanding. The installation was long and slow. I did run separate 5/8 raw water hoses (4 lines) from generator room to the aft cabin AND BACK. This is about 100ft round trip. THE FLOW WAS INADEQUATE. A week or two later i added two bronze though hulls about 4 inches above the waterline on the side. (at same level as some other discharges). This is working great! I can see the flow from each unit separately with i find very helpful. I have also fabricated a set of crossover valves so that either pump can service either side or both at same time. It also works for back flushing.

Here are a few pics from aft cabin install. 56 MY

Great info! Thank you all for replying. Sky I will be down to
pick your brain if that’s ok
