2004 Land Yacht Dash Air Conditioner

I have a 2005 LY 30ft SO with cab AC that just does not want to produce enough cold air. Has anyone put a bigger unit in and if so what had to change? I live in AZ so I am dealing with over 100 deg all the time.

Is the air not cold enough, or is there not enough air flow?

C-21 -- In our 2004 Land Yacht, we installed a curtain behind the seats in the driving compartment and used it some. On our hot days, we ran the cab AC plus the gen set and both roof airs. I have read somewhere that the gen set uses about a gallon of gas per hour (have no idea if this is correct), but whatever the usage, I thought it was a small price for a comfortable coach.

If you have a 30 amp coach, have you added a means for a second 20 amp hook-up, so you can run both ACs while in campground?

Air not cold

The last time I had the AC checked they had the air at the dash outlet at 60 deg which I believe met spec. When it was at that temp the air flow was sufficient but marginal in terms of keeping the front seats cool (not cold but acceptable). Now the air temp is way above that so I think I might have a leak and will have it in the shop to test it this week. But overall, I am wondering if there is a way to change the cooling unit to get the cab area cooler? Maybe put in additional outlets (say under the dash on the feet) that could get more airflow in the cab area? I have got to get this better, AZ heat is not merciful.

Also, if someone has the plan for adding a 20amp circuit for the back AC for the campground to run both AC's at the same time I am very interested.
Thanks

Sounds like your cab AC needs professional service.

Take it to a shop that has the right equipment AND the right mechanic.

The dash air will not keep a coach cool while traveling.

As mentioned above, we also learned to keep a curtain of some kind just behind the captain's chairs. This kept the cockpit comfortable enough, although the rest of the coach got hot and took both roof ACs a while to cool after parking.

Genset and roof air is the only way to travel and be comfortable.



Regards,

JD

If you haven't done it yet take it in for service.60deg at the vent is not spec you are probably low on charge. When its real hot 100 or close I run the generator & the front roof air along with the curtain. I travel early if I can.

Just to update. I did take the unit in for AC shop and they have told me air flow is fine and that the cold at the outlet was ok. That was in July, I am going to take it back in to check charge to see if we have a leak since when I compare the feel at the dash to anywhere else it is lacking. I do need to run my ac off generator when on the move at above 100 deg out side. Does anyone have the actual spec on temp from air stream or the manufacture Specific Climate Systems Inc. at the dash?

If they are telling you temp at outlet is ok at 60deg you need better service. Put a reg thermometer in the dash vent.Should be in the 40's. on 100 deg days there still wont be enough flow to cool that much glass so use a drape on a spring rod behind the cab seats & run the front roof ac off the gen.

Agree with Garypk: you should have 40 degree air. step one is getting the dash air to run as good as possible. If you have a Workhorse factory resource or a really good HVAC repair place they can check coolant pressure and also inspect proper door operation. There is a vacuum line across the top of the engine compartment that operates the door and if it leaks or is cracked the door may not open all the way. My vacuum line crumbled in my hands and now I have cold air.

I did not install a curtain but did set up the front a/c to run when I turn the gen set on from the dash so I could turn that on and off as needed to trim down the heat. This has only been for about 85-90 degrees before I replaced the vacuum line.
