2019 Georgetown GT7 dash a/c

We just purchased a new 2019 Georgetown GT7. The dash a/c blows slightly cool air but not cold. Took it to the Ford dealer for repairs. After having it for 8 weeks and replacing multiple Part and consulting with Evans Tempcon they told us it is within factory specifications of 65deg. When driving it home it is more like 70-75 degrees blowing from the vent. It is 70 when setting still and 75 while moving. Has anyone else experienced this problem? We have owned a number of class A motor homes and realize the dash a/c will not cool the cab but the air coming out should be cooler than 70. Btw we live in Florida and the outside temp was 88.

Ours is the same way. When we are heading west in the later afternoon when it's 90 I'm usually sweating my butt off. I don't know if it's because the air return has to travel so far to get to the vent. My experiences the longer we have been driving(hotter theengine gets) the warmer the air.

Inefficient dash AC has always been a problem with F53 / E450 by Ford... We run the Coach AC if we are expecting higher temperatures...

I have spent a lot of time trying to get the dash air colder. But after recharging my system several times and insulating the evaporater coil compartment which is located in the engine compartment (most cars and trucks the evaporator coil is located in the cabin)the lowest temperature I was able to get was 56 degrees. As the outside temperature increased so would the temperature of the vents. I have concluded the ford dash AC is a very poor design. On the ford f53 the condensor coil is located behind the transmission coils so this reduces the amount of heat removal from the system. There is not much that can be done to get colder air without installing a larger condensor coil. Now I run the generator and roof top AC unit when its neccessary.

Yeah....
Ive conceded the A/C efficiency in these Ford F53 motorhomes is pretty poor...and other brands of motorhomes (Thor, Winnebago, Coachmen etc) all report the same.

Aside from running the roof air conditioners when really needed, here was my solution for getting bettter results from the dash air.

Dash AC Problems

Wow, I,ve been fighting this very problem for 3 years. I just had my 2015 Georgetown to the factory in Elkhart, ID . There is another posting on this site with all my complaints. I don't know how to direct you there however. Sorry.

However: here is what they did. Evacuated the system of 134a, all the oil and held a vacuum on it for a time. They then replaced the oil and freon to 2.75 LBS as required by the EvensTemp Con Bulletin. Improvement over the old charge was about zero (0) after driving a few miles. Go figure.

Please look up my other posts and send me a reply. I'll be glad to converse further as this issue really TICKS me off.

Thanks for all the information from everyone. I absolutely love this coach but the dash a/c is unbearable and according to the Ford dealer it is operating within Evans Tempcon's specification. 65 degrees from the vent is sad. I do not believe it is a Ford problem. The dash a/c components are from Forest River and Ford. It becomes tricky when it comes to warranty repairs. Some parts are covered under Forest River warranty and some parts come under Ford warranty. The Ford dealer had our motorhome for 8 WEEKS and the sad thing is ....it is no better. I think it is a defective design form either Evans Tempcon or Forest River. We had a Newmar Scotsdale previously on the same Ford chassis and the dash a/c worked beautifully. Maybe techs from Forest River should visit Newmar to learn how to design a proper ac system. Sorry for the rant I am just really frustrated with the situation. We have owned several class A motorhomes and have never encountered this problem. But from the posts here and researching the problem apparently it is a common problem. I guess we have been lucky in the past.

You had a Newmar -- but was it a pusher or Gas? That is a big difference.

I know the Newmar my sister had -- it was just as bad as my Georgetown in regards to the dash air (same F53 chassis).

It really is hard to believe that there is this much of an issue with getting these things to blow cold air, i really think they just figure out the most simple excuse and give it.

I end up running the generator and aim one of the roof A/C vents down on me -- not a huge amount of cool, but that combined with the "cool" (okay, being nice with that word) air from the dash, i don't sweat too bad. Running both A/C's of the genny is about the only way I have found to keep the coach reasonable -- well, at least keep the passengers from #$$@% the whole time.

Someday Ford or someone will belly up and take responsibility for a very poorly engineered system and maybe, just maybe fix it.

It was a gas 2005 Newmar Scottsdale on a F53 Ford chassis. I don’t know what the temp of the air coming from the vent was... but it was cool enough to be comfortable. Maybe it is more of an issue on newer motor homes than old. Maybe mfg are cutting corners on newer models. Wold not surprise me.
