Are there replacement options for the basement units in these coaches built in 1994? Basement replacements, roof mounts, mini splits?

I think these are Dometic, but I am not positive.

Any thoughts are appreciated.]]>

Please note that this is a review of an installation and rebuild of the drivers side AC basement; also this is a 2T system using, the now outdated, 410A refrigerant. The air handler was the controlling device as it had to fit the space, i.e. had to fit in the basement height and also had to be oriented to have a return utilizing the plenum (air return) cavity that is already in place and in addition have the ability to connect the discharge to the internal air duct. We chose a Goodman AWST air handler, however it required substantial modification to fit in the basement; it also required modification of the plenum. Once the Coleman AC unit was removed it was decided to rebuild the entire basement since it was apparent that modification and rebuilding/strengthening the plenum box was necessary. The air handler was cut down to a height of 29 inches to accommodate the height restriction and the blower was replaced so it could be reconfigured to accommodate a side discharge towards the duct that runs down the spine of the coach. As previously stated the condenser that was installed was mis-matched (this was a Goodman GSXS with a Goodman GTST thermostat) and therefore the system would not work. Again, another learning curve to ascertain what type condenser would work with the AWST air handler (changing the air handler was not an option as no other air handler that was researched could be cut down as described above). During this phase of research and learning a contractor friend recommended a HVAC mechanical contractor and this proved to be invaluable. Mechanical contractors by their nature are accustomed to building and modifying custom HVAC systems; this particular HVAC mechanical contractor actually enjoyed the challenge, which facilitated completion of this project. We ended up using a thru-the-wall condenser, a NCP 4244. This also had the advantage of improving our design as it could be bolted to a Morryde sliding shelf thus allowing access to the air handler, 220v wiring and the plenum itself for maintenance and repair ( a feature that originally had been desired but could not be accommodated due to height restrictions). In addition we used no kink flexible refrigerant lines to facilitate the movement of the condenser as it is pulled out on the sliding tray. To finish the set up a standard Nest thermostat (not the leaning thermostat) was used as we could employ it to not only control the AC but also use the same thermostat to control the Aqua Hot heat (note that the AC power to the thermostat is 24v ac and therefore a transformer changing to 12v dc was added to the Aqua Hot boiler at the relay) in the bedroom where this thermostat is located. The system now blows cold strong air thru all the wall ducts which the Coleman did not and the split system should ensure many years of reliable air conditioning. Note that the one remaining phase of the project is to open up the basement door with a larger cut out for air flow so the condenser can draw in cool air and discharge hot air.

We are doing a conversion on our 40 xl, it has 3 cruise air units which we will be replacing with a single LG 24k btu 3 zone heat pump compressor using 12k btu LG Art evaporator in the rear and a 12k btu LG Art Mirror evaporator in the front using two zones to start with. In our Newell we have the art up front and the mirror in the back plus a duct unit over the refrigerator. We normally only run the 12k art and the 12k duct unit for the whole coach.

This motor from Grainger works. https://www.grainger.com/product/3RCX4?c...ad2d102e99

The belly band fits around the body, the shaft is the right length and diameter. You will have to saw/grind the mounting screws off both ends. You will also have to demount the included start cap. You have two equal choices then, use the included start cap 5MFD, or use the original fan portion of the original start cap.]]>

The original valve is obsolete and was a custom OE made for SCS. Lovely, now it's made of unobtanium.

I ended up using a type of TXV that uses a Sporlan EQBODY 3812 OD STR, a QC2 168074 cartridge, and KT NGA 43 Power Element.

Huh? The reason for so many part numbers it the valve I used can be configured in many different ways. All that sounds like goobly gook, but your AC tech can use that info at the local AC supply place to get a replacement valve.

What you are looking for is a one ton, internally equalized valve, sweat fittings for R 22.

The above configuration worked great with the unit specified charge of 36 OZ of R22. It produced 10 degrees of supercool (perfect).

I had to do a bit of plumbing work to fit it in the unit because the configuration of the inlet and outlet plus the size of the outlet is different than the original.
