I need to remove the old air conditioner to make room for a new one. The old unit is mounted below the floor in front of the galley, below the seat that faces forward. I worked on it once and the hardest part was access. There is cabinetry and partitions everywhere. Since the old one is trashed, I don't care how I get it out as long as I don't hurt the boat. I can dismantle it into smaller pieces if needed or whatever. Any tips on how to remove it? Also, anyone have a new AC in their H49 who likes it? Which brand/ model? Thanks to all in advance. Bernie
Need tips for removal of main cabin AC in 2007 Hunter 49

Sorry to here your 2007 AC is trash and hope mine last many more years on my 2007 h-36,maybe to make things easy cut and remove the compressor to make removal lighter,I would try to remove the whole thing so when adding the new one it will go back in easy,maybe try removing some screws that hold furniture and than remove some of the wood just so the new one can slide in easy.
Do some research here and on the internet for best reviews and the new one should be better built to prevent rust,I opened a second drain to help remove water from sitting in pan and my compressor bolt down feet are rusting for sure.

This is simple
Remove the salon table.
There is a floor panel with a bunch of Philips head screws
Remove this floor panel
You will now have full access to the airco unit.
Note that there is a relay box in the same compartment as the hot water heater.
Basically, this has 3 relays in it which control the sea water pump. So, if any of the airco units turn on, the pump actuates.
The pump runs water through all 3 airco units, irrespective of whether they are on or not.
You will see that the airco has a large hose adapter connected to the fan. This hose goes to the vertical plenum which takes air up into the overhead vents.
Good luck!

You amaze me it seems you have taken everything apart on our boats. I also have a question concerning the middle AC unit ... some where the AC raw water intake or exit to the thru hall is leaking water. I think it is right after the three way split after the pump that sends the water to all three units. I can't see the 3 way split ... is it under the same floor section you are describing above .... Thanks for any help.

That's a really good question.
Obviously I know where the pump is, but I've never seen a 3-way splitter.
It would be hard to see, as the pump hose goes under the sink area.
Now that you've got me thinking about this, I'll track it down.

My compressor seized after a couple of years of service. I replaced mine with a Mermaid 16 instead of 18k BTU. The main reason for selecting the 16 was that it had a similar footprint as the Marvair. The orther reason was cost of the unit. I wish I purchased an 18 because the 16 is on all the time and I ended up redisigning the connection to the ducting on the boat anyway. I did take my old one appart because it did not fit in the car, but I was surprised when I took the parts to the recycler and got 135 for the compressor and 20 for the copper lines. If you still have refrigerant in the unit take it to an AC repair shop and you may get a few bucks for the refrigerant. I removed the factory plywood piece under the AC, installed a 3/4 marine grade plywood with a few coats of epoxy paint and added a little giant 230 volt drain pump to keep the bilge dry. If I remeber The challenge of replacing it with a different brand was the hight and the interphase with the boat duckting.

pulled the floor section up over the weekend and the three split wasn't there but I found my leak a crack in the hose which I replaced ... while working to replace the hose I hung my head upside down into the bilge area and low and behold the split is in the bilge above the pump right under the floor .. I must have been blind when I was looking for it before. All's well that ends well the leak was found and is now fixed so I am no longer pumping water into my boat.

the a/c unit as artboas says is easily accessed after you take up the floor it is only six screws so it comes up easy ... in the process I found lots of left over factory junk such as old used tubes of 5200, drilled out bung holes pieces and left over wire sections etc left behind in the nucks and cranies all of which are now in the trash.

Yes, I agree that pulling up floor panels reveals tons of leftover bits that nobody spent the effort to vacuum out.
I did review the hunter documentation, and the split is right at the pump (as you found)
On a slightly different point, a good friend with a current beneteau asked me to help troubleshoot an electrical issue. There is no question that Hunter's wiring practices are some of the best in the industry.
