Most of the time it is going to be Dometic brand, and a Penguin 13.5 or a 15 K AC unit and it probably has a heat pump in it, the Dometic Penguin is a low profile unit. You probably have a 4 button thermostat on the wall so you will have to order the correctcircuit board in AC for it to match thermostat on the wall.

Ron, are you currently having problems or just pre planning for failure ?

Most times just the starting capacitor can be the problem which is an easy fix.

Thanks, Art, and thanks, Steve.

1. Last summer, if I recall correctly, one or two of the units would blow cool, but not cold.

2. The middle unit does not produce good heat.

The living area unit has an digital thermostat. The kitchen and bedroom have the older manual thermostats.

These could be simple and straightforward issues for repair. I am not handy with HVAC in any way. I was thinking along the lines of bringing all three up-to-date with the latest available units. Important for the wife to be freezing in the summer, while I have to bundle up. We generally agree on heat, but then again, I am very cold natured and anything below 70 degrees can bring me a chill.

Ron,

A few years ago, I replaced all three Dometic 13,500 BTU units. I replaced them with 3, 15,000 BTU low profile Dometic Penguins. The 4 button duo therm thermostat is not compatible with the new units. I found it better to replace the thermostats than change out a control board. With the new thermostats, the wiring between the thermostat and air conditioner is compatible so this does not need need changed; simply plug it in.

could just need cleaned out. would spend $$ on service call before throwing new units at problem. Most will have r-22 on service truck,clean outside condenser ,and basic check out. hundreds instead of thousands of dollars. R422 is a direct drop in I’m told. Happy wife happy life!

[glen]

There is a misconception that R-22 is expensive or not available. It has actually got a reasonable price as demand drops, and it is readily available. There are drop in replacements,, but I know for a fact AAP has tested multiple refrigerants and the original R-22 still remains the most efficient and delivers the best performance.

Call AAP and get the information direct from the people that have produced Cruisairs for 40 years so they know the product.

See quote below. If you want is you probably need to buy it now.

The R22 phase out date means that after January 1, 2020, HVAC systems that use R22 will be obsolete. If the repair requires adding R22 refrigerant to the system, the only options will be reclaimed and previously-produced R22 refrigerant. … In the lead up to 2020, R22 can still be used in repairs and maintenance.Jan 26, 202

[Art]

And yet today R12 is available and being used. And it is not “legal”.

It is not likely R22 is suddenly going away, nor is it likely it will not be available. Speak to AAP because they are dealing with this and can provide advice regarding refrigerants.

[steve]

The only problem is the roof AC’s don’t have ports in them, If that is the problem you need to find some one that will get on the roof and solder in the correct ports.

You can still readily get R22.. I have a 25lb bottle and a couple 2.2lb bottles (that I carry with me). I only usually have to put gauges on and bring it to the correct psi once a year. ..

R12 is also available though more expensive. its take over a decade to get to this point, and yet its still available if you need it. Technicians are technically not allowed to work on/add them but you can do it quite easily with a set of gauges. You can have them work on removing leaks and actually working on the unit. They (or most) just cant add the actual refrigerant in to the system.
