Finally a quiet AC
I replace the Dometic AC on our 2018 Bigfoot 25RQ with a Houghton AC3400, a 13,500 BTU model with heat pump. Easy install, and it is whisper quiet. We can listen to music, talk, watch a movie, etc when we have shore power while the AC or heat is on high. It really is that quiet.

Sounds like a nice alternative. We have a 2015 Bigfoot 25RQ as well, and the factory 11000 BTU a/c is adequate but it sounds like you are standing next to a Boeing 737 when it is running! Don't have any experience with a heat pump. Let me know how it works out for you.

We had a heat pump with the ducted Dometic AC in our AirStream Flying Cloud. We used it a lot more than cooling with AC. The only problem was hot air rises and the source of heat was in the ceiling.

Nice! I've been considering that myself, more for the heat pump and power efficiency improvements than anything. Did you run across any problems or challenges with the install? Clearance or fitment either on the outside or inside? Or was it just a matter of unscrewing the old and installing the new, plus a bit of wire splicing?

Easy install. I have a small front end loader that really helped getting the units off and on. Just waited until my wife was out. Took about an hour total. Well engineered. We’ll be camping with it in a few weeks, so will test hot and cold in “real life.” Pleased so far. Much much quieter.

Thankyou for your post. Will have to look into them. Hate the noise.

How is it for current draw? Any chance it would be low enough current to run off batteries easier than the ole Dometics?

From the website,
https://www.recpro.com/rv-air-condit...te-non-ducted/
When running on 120 Volts ac:
Running Watts for Cooling : 1550W
Running Watts for Heating : 1100W
Rated current for cooling: 14A
Rated current for heating: 10A
Maximum power input: 1700W
Maximum current: 15.5A
So, for a 12Volt-DC-to-120Volt-AC inverter running at 80% efficiency, I would expect a draw of about 150 Amps from your battery.
So, what, maybe 30 minutes run-time from a 100 Amp-hour battery?
Also, US$1,500 plus shipping is <almost> what I paid for my 1977 13' ten years ago. :-)

There are some Oliver owners replacing the Dometic with a Houghton unit and are very happy. When my Dometic AC bites the dust that’s what I will do. Maybe sooner, we can’t stand the noise machine we currently have.

A question I’m asking Oliver
I asked Josh about this the other day and all he said is that Oliver is “evaluating “ other units. This may be the deal breaker that forces me to a Big Foot as I can order without Ac and put in what I want.

Just make sure that they prep it for AC!

AC units have many components that can contact one another, producing vibration and noise. For example, belts, hoses, and AC housing can vibrate and create sound. It would be best to cover the hoses and pipes to prevent them from rubbing against one another. You can also insert foam or rubber cushions between the RV AC unit and the RV rooftop. Adding foam around hoses and pipes also helps when making RV Air conditioners quieter.

Regular AC unit maintenance can help you reduce noise and achieve a quiet air conditioner. You can also reduce the noise from your motorhome air conditioner by tightening bolts, adding insulation, and installing a silencer.

This is a fairly popular conversion on the Escape models. This is a long thread on the conversion of two trailers.
https://www.escapeforum.org/forums/f...all-21313.html
I think the heat pump is only available on the largest model, 15K BTU. The problem is that small trailers don't need 15K BTU (unless operated in the south west in the summer) and running a large unit will cause it to short cycle and not remove humidity properly, nor cool properly. Unless your A/C was clearly undersized to start with, you don't want to oversize it unless you have good reason to and realize the issues that can crop up with short cycling.

I camped next to a fellow who had installed a small "mini split" unit on his non-fiberglass trailer. The outside unit mounted on the tongue and the much smaller inside unit was mounted in a cabinet. Super quiet, super efficient and provides both heat and air.
