My Model 260 KZ Spree Connect's A/C would not keep up during the 95 degree weather this past weekend. According to my inside thermometer it climbed to 88 degrees during that time.
Any ideas? I have blown out the radiator part of the A/C and I don't have any problem of it recovering as the sun goes down.
Would blocking the two sky lights make a big difference? |

There are a lot of unknowns here. Do you have your window shades up? Is your entry door open? Was your camping site in full sun? Was your awning out to help create some shade? Were the skylights hot to the touch?
I know my mother-in-law has plexiglass on her screen door, leaves the entry door open and always has all the shades open... but always mentions that her air conditioner doesn't cool the camper. Conversely, I keep mine shut up tight as a drum when it gets hot and my air keeps up for the most part.

Blocking the sun from the sky lights will help some. I had 3 in my old KZ trailer and I kept one of the foam vent cushions in each one. The less sun and heat that gets in, the better off you will be.

My shades were always down, my door closed and we were in partial shade to mostly shade in the afternoon, and my awning shaded the one side in the morning.

If you could measure the temperature of the air going into and out of the AC that will tell you the condition of the unit. Many use the figure of 20 degrees difference.
A cheap digital thermometer from Harbor Freight would be useful to detect warm spots on walls and ceilings and check the AC output. It will double as a tool to check for hot tires, brakes and hubs.
You should look for air leaks inside the ceiling and air leaks between the input and output of the AC.

Lynnmor is correct. The range is 17 to 20 degrees difference from return air to supply air. Also if your unit has the dump dampers to bypass the ducted system open them and leave them open. Airflow is key to any unit working properly and the ductwork in most rv's is not adaquite.

I had the same problem with the AC in my Spree. I took the cover off of the ceiling and found that the divider that separates the return air from the supply air had fallen over. That lets the supply air suck right up into the return. I straightened up the divider and installed a couple of screws and some tape and it worked like it should. It might be worth checking out.

I have an 03 new vision and it needs something, wondering about a small shot of Freon, do they make Freon shot cans like for autos, only for RV'S?

You likely have no ports to attach a can, they would need to be added. Usually if refrigerant leaked out the unit is replaced. Clean the outdoor condenser first, it might have considerable blockage after 15 years. |

There are no ports on an RV A/C because the amount of Freon in there is so small a tiny leak from a typical schrader valve (and they all leak) would empty the system in short order. |

lynnmoore, your right on the money no air was getting thru THAT condenser, no light could be seen thru it either, made a good 5-10 degree difference!

Lynnmoore isn't wrong very often.

I found that covering my skylights on very hot days 90+ makes a huge difference. Middle of the day under full sun you can really feel the heat coming in through them. Did a test on a day that hit 95 with trailer in full sun sitting in my driveway. I got on the roof and set a Rubbermaid tub over them and inside temp dropped 8-9 deg. Test done with all shades and doors closed on my KZ Connect 241RLK with the stock ac unit Awning rolled out also
