Jayco Pinnacle AC question

[CapeCodGuy]

We have a new 2017 Jayco Pinnacle! The temperature outside is 92-93 degrees and we have the AC on High cool inside the RV!
The AC is running but temp won't go below 83 degrees!

Any help is appreciated!!!

Do you have 2 units or just one?

[CapeCodGuy]

Two units

[CapeCodGuy]

One in Livingroom and one in bedroom

I am searching for the posts and can't locate them right now. But there have been some reports of a piece of the ducting that is not secured in place falling and blocking airflow from some of these units.

I'm not familiar with exactly what is on a pinnacle but I'd assume they are all similar units.

My dual units don't keep up like at home but they definately cool the rig better than what your getting.

Also we turn ours on and leave them on. It takes a long time for a HOT rig to cool down once it is heat soaked.

We keep the doors closed and windows closed as well.

If you put your hand up and the vents... does it feel cold?

And also sometimes we open up the quick cool vents and bypass the ducting that helps a lot as well especially for the initial cool down after travelling.

That's how our Pinnacle AC is also. I have not had time to check to see IF it is leaking in duct work, but plan to.

Ya'll, please keep us posted, we are one breath away from pulling the plug on a new 36FBTS Pinnacle and there is no way living and also primarily camping in Florida that we can deal with inadequate ac. Thanks all

I have a 2016 FBTS and ya u gotta run both ac units but I can cool mine down. I had a problem with the bedroom unit kicking out compressor. Remove the inside cowling and there is a fiberglass piece that separates the blower from blowing air back into the evap side. Mine was just laying in the cowling. Put back in place and taped real good with ac duct alum tape. Also make sure the temp sensor wire end is against the evap fins. Sometimes the sensor comes loose from the fins. On main unit u have to remove the top cowling and look down inside for the piece that separates the evap from condenser. I have not done that yet but another posted that it is real tight to get to. My bedroom unit would keep kicking off the comp on low fan because of the piece that was loose. It did not kick out in high fan but was not blowing as cool and like Grumpy said also was not blowing the air into the duct system but just a little.

It was so hot today...93-94 degrees with. No shade!! Today was day two of extreme heat! Both Units were doing the best they could...but inside the RV it was still 84-85 degrees with all shades shut!

We went out to dinner and when we came home the sun had set and inside the RV it was very comfortable and cool...perfect for sleeping!
I thinks it's just one of those things that will happen during a three day heat wave of 90 plus!

We just bought 2017 pinnacle 37MDQS. 2 AC units. It is set up permantly in leased campground spot with direct sun. I do not have any cooling issues. Matter of fact it gets down right cold. We traded a park model with only 1 ac because we were so hot. You may have an issue with flow. Only problem area in my MDQS is the mid office gets warm if you shut the door. I don't feel good flow from vents in this room but all other vents feel strong

There is a divider that separates the return air from the out going cool air. Check this to make sure it's in place. It's a good idea to get some foil tape to help reinforce it. I have had this come out of place on two different trailers.

Bed room air this divider was out of place.

I can not get to the living room air from the in side.
I did get on the roof and checked living room unit. Had to pull off covers to see inside. It looked ok. I did add some tape but it was very hard to get to without removing the whole A/C. Just did the best I could.

We do the same thing. Helps a lot but we have never had problems cooling. Can easily bring it down to 73 to 75.

[norty1]

are both units 15k btu? Mine are and we have never had any problems.

[Bauernfeind]

I too have had similar problems. My bedroom a/c was finally replaced b/c it kept tripping the circuit breaker. When it's above 95 I can usually get the inside temp to 78 - 80 degrees but no cooler. The bedroom divider was an issue on the original a/c unit but so far not on this one. Keep both a/c fans on high to prevent units from freezing as well. Buy vent pillows for the fan vents and insulation foil for the bathroom roof sky bubble things. Over 95 I often close the door to the main bathroom and put a fan on the floor from bedroom to blow into the living room.

Check the ceiling vents. I taped all of mine to keep cold air from going into the roof cavity. Also, check the dividers as mentioned above.

I have 2 ACs on my 355MBQS.
After checking the above, I am able to reach 73-74 degrees on a 95 degree day with one AC. With 2, I can get it downright cold....

Our dealer told us the AC units are engineered to cool the inside to 10 degrees cooler than the outside air. I don't know if I buy that, but that is what they said Coleman (manufacturer) states.

[Rock]

Here is real good advice, never believe a freakin thing the dealer tells you and take it as BS. I have been lied to my face and have returned and confronted several service managers who have done this to me. The best one was when I had him on my roof and confronted him to his face. I got my point across since he crawled on his hands and knees to the ladder. You know how slippery them roofs can be.

10 degrees below ambient is unacceptable IMO.

15 to 20 is what is expected. We have been hitting 95-100 here in Seguin TX last couple days and my 264bhw with 13.500btu has been maintaining 80 - 82 direct sun. have not done window insulation or skylite or fan yet.
