Although this is a RV forum I would look for information on this type of problem on a HVAC forum where you are likely to find the professionals who can provide assistance with troubleshooting your unit.
The AC units for RV's are designed in the same manner as the ones made for home use and to run on 110 volts regardless of where the source of the power.
AC units require a lot more power when they first start so extra amps are needed and capacitors are used to partially compensate by storing power to feed in an initial burst to the compressor motor. You will find lots of related posts on these forums covering this in depth with regard to RV's.

There is enough expertise on this forum to solve just about any air conditioner proble that you can think of including Doug Rainer who is a certified RV tech with 30-something years of experience. There are also others of us who have been in the AC business for some time. The problem is that when someone does post accurate information that would resolve issues, some armchair technician or retired engineer wants to argue us down and give his take on the subject after going into great detail about how wrong we are. As a result, many of us have stopped posting and turned it over to the people who know everything about everything and we just sit back read, and chuckle before going to get another cup of coffee.

Turned on the a/c and although at first it felt like cold air was coming out it just didnt cool enough, and after a little while the air didnt seem cold anymore. The boyfriend hooked it up with a 'regular' extension cord and we figured that it probably wasnt getting enough power. So boyfriend bought the big fat extension cord from an RV place and plugged it into a regular outlet at home last night. again, it started cooling, and then just petered off. I stated that i thought you werent supposed to hook it into a normal wall socket, that it needed more power. He disagrees. Who is right and could that be the problem with my a/c or do i need to look further? Thanks!
I know the AC is on a horse trailer. I know you just bought it. When did you buy it? Has it ever worked since you owned it? Horse trailer sticks out here. Horse trailer was on a horse farm? There are more creatures on a farm, than a subdivision. Although a long shot certainly worth a try. Was the AC covered during the winter months? What was it covered with? The creatures I refer to used the inside lining of my winter AC cover to build a nest and jammed the compressor on my fiver! Worth a try, you do not want to pay someone for putting blinker fluid in!

I work with HVAC professionals and get three different industry publications and participate on HVAC forums, both professional and home owner oriented. No way is the same level of knowledge present on any RV site.
A RV technician is going to know how to replace not repair items. And what is a RV certified technician certified in and by whom? By Coleman or some other AC manufacturer? When the AC on my truck or other vehicle is not working properly I take it to a auto AC repair shop, not the car dealer's service center. The GM technicians are good at what they do but it is ludicrous to think of them as experts in anything.
As the great Yogi said it is not what you know but what you know that ain't so that gets you into trouble.

Feel free to ignore anything I write- I insist. I have made a fair amount of money replacing roof top air conditioners that have been "repaired" by "real" HVAC technicians (even more money repairing rigs fried by "real" electricians installing 30 amp outlets)

It's almost impossible to help someone who knows almost nothing about the problem.
I run out of patience with anyone who doesn't give year, make, and model right off the bat. Also, the history and general condition of the equipment is helpful.
Then, if they don't reply to a question, you can just "forget about it....."
For those who disrespect Doug and Chris,......shut up!

As the great Yogi said it is not what you know but what you know that ain't so that gets you into trouble.
1. I am factory trained by both RVP (Coleman) and Dometic
2. HOME HVAC techs have NO IDEA how to fix RV AC unit sas from their posts on these forums with a lot of lack of knowledge AND I repair a lot of RV AC units that have been "repaired" by Home HVAC techs. They are knowledgable about home systems but NOT RV systems.
3. As a tech who worked for both a GM dealer and was an RV tech at the same dealer. ALL OEM Service techs are required to go thru ALL technical schools put on the GM and Ford and such. This excludes BODY schools as Service techs at a GM dealership do not work on body damage. FYI, when we were a GM dealer I was trained at the GM tech school for Cruise controls/AC repair and you HAD to pass the test to get your certificate.
4. A GOOD RV tech DOES repair far more than you would ever know. The fact you would make such a statement shows YOUR total ignorance on how the world works. As I told another poster months ago, you think you know so much?? Come be beside me for just 1 week and you will NEVER make such idiotic statements again. Are there BAD RV techs? Sure, just as there are BAD Doctors/Lawyers/Engineers and so on.
5. Quick question for YOU since you partcipate on HVAC forums. What is the ONLY way to test for correct charge in a RV AC unit? Doug
