Maybe I should have answered your question with, I have experienced no issues with running the Houghton ac while driving. Had them for a couple years.

Jim
Just wanted to let you know that I moved the thermistor on my rear AC and placed it in front of the over head light so its blocked from the air flow and I like the cycling pattern much better now. Think I will do the same to the forward AC, not sure if the AC gets some air from the discharge vents back into return air but moving the thermistor is an improvement.

Engineerlt- I gather from your last post that there is a movable thermistor on the Houghton units. True? If so, what does it take to move it?

Lance: Thanks for that info! Will give it a try. I love the Houghton's but they do cycle a lot more that I would like.
Hope you are enjoying your PC! Any new projects?

Hey Jim
Sold our home in FL and bought one in TN. Got tired of dodging the hurricanes, and some of the political issues. So we were in the PC for 5 months while we were house hunting. I am glad to say that the PC was excellent. It never gave us a bit of problems and was just a good time... So I have been busy with the new house trying to get some things done before we go to Fl for a couple months during the winter. Not many mods since I sold our home in FL and there isn't many that I can think of doing, seems my imagination has dried up. 

I hope your PC is working well for you and you are getting out to use it.

Very Respectfully
Lance

Wow Lance, Congratulations on the new home! Glad your PC served you well during the search.
Have to ask, with all those added storage areas, were you able to remember where you packed everything?  roflol
We haven't used the PC much this season due to my wife's Moms health issues. We've needed to stay near home but hope to get a few local trips in soon.
Only projects I've done to the rig this year are a dual pane window repair, some waterproofing steps to my furnace which took in water that prevented the heat from working on our last trip and chased a couple of squeaks while driving. The one thing that is really bugging me now is the sound quality of the truck radio. I replaced the radio with a decent Sony unit and the speakers with Infinity coaxials but it still sounds like crap. Need to double check the wiring and maybe add a subwoofer.

Enjoy the rest of your summer!

I got tired of the extremely noisy Dometic AC unit in the front of my coach and replaced it with one of the Houghton quiet AC units from Recpro. Now I have two of the Houghton units. It's amazing the difference in noise level. We can now carry on a conversation without yelling and not have to turn the TV wide open to hear it when the AC is running. Camper's Inn painted it to match the original units just like they did the rear AC unit they installed before I picked up the coach.

One question I have for other owners of the Houghton units is how well does yours dehumidify the coach?

The compressor cycle is not very long and doesn't seem to run long enough to drag out the moisture like the noisy Dometic. There is a big reduction in the amount of condensate running off the roof. I have tried running them on the dehumidify setting with very little difference.

Kevin: I also have two Houghtons on my 2552 and have had similar experience as you describe.
They do cycle more than I think is ideal.
I attribute it to the confined spaces in our PCs. The Thermistor that senses room temperature is inside the return air duct in the middle of the AC unit.
Cold air from the discharge  vents get recirculated into the return air turning off the compressor prematurely.
I have confirmed this using an infrared thermometer aimed at the return grill and see that it cools much faster than the room itself.
For now, I have been compensating this by setting the units a few degrees colder than I want the room to be and it seems ok.
Forum member EngineerLT has done a couple of mods like putting an enclosure around the thermistor to slow the temperature change at the sensor and has reported good results.
He recently relocated the thermistor to outside the AC unit on the ceiling near the unit and  got even better results.
I plan to try relocating the thermistors to a wall near my heating thermostat but still waiting to get a "round toit"
When I ordered my 2552, Ed, the electrician at the factory said he usually runs extra wires between the ACs and that location but I have yet to verify.
All in all I am VERY happy with my Houghtons and they cool very well but due to this short cycling, the room never reaches setpoint. Setting it a few degrees lower gets you where you want to be.
BTW I generally do use the Dehumidify mode as it is even quieter and seems to cycle less. Still need to set it low though.

Are the Houghton a/c units capable of having an external thermostat like the Dometic a/c units, or your home central a/c units?  Or are they like window a/c units that just have a dial that essentially goes from Not so Cold to Colder... Not a set temperature.

The Houghton A/C's have a digital thermostat built into the unit. Set a temperature and let it run. In the event of power loss the unit will remember where it was last set and return to that setting.
