Question.Does anybody know of Air-conditioning Engineers who are capable and willing to look at and get my Dometic 2200 airconditioner working.The unit is blowing and heating OK but not cooling.I assumed like earlier car AC,s it was a matter of recharging.However I now understand they are sealed units and that after 6 -7 years they should be replaced!.At £2,500 not too pleased at that thought,and does not seem very environmentally friendly .Ideally if there is anybody the Cheshire area would be good but I am beginning to realise I may have to travel.Strangly every Dometic installer I have contacted does not offer a servicing facility.The unit is 7 years old and hardly been used.
Any tips any body.

Does it heat by reversing the system or is it just a heating element in it?

They are sealed, like all air conditioners but they can all be regassed even if there is no gauge access point one can be fitted for a few quid. Whoever said they only last 6 years doesn't know what they're talking about. Car/van cab A/C sometimes needs regassing because the compressor drive shaft is driven from the engine and the seals round it can wear and leak, also stones and salt can attack the condenser. But the one on your roof has none of those problems and should last years.

Hi, these units are hermetically sealed for life.

As such, they don’t usually need re-gassing or as I like to state, re-charging. As this is the case, they don’t usually come with an access point or charging stub. That said, we can always braze one on.

If you say it’s not that old. I doubt it’s a compressor issue. As the compressors are pretty much bulletproof .self, lubricating and as they are sealed, not usually an issue .

Where are you based in the vast county of Cheshire? .

Send me a PM if you need more advice or assistance?

Hi, I have the same B2200 which doesn't produce any cold air. The Compressor runs as do all the fans and I can't find any evidence of oil/a leak in the system. High pressure side doesn't get hot either. I am in Burnley and happy to travel. (I tried to find DM but can't locate it)

I’m interested in this thread too as I have a Dometic air con on the roof and currently here in Spain (38degC) it’s blowing warm air.
I’m in a west Yorks so not too far from Burnley & Cheshire depending on where in Cheshire.

Maybe you can't send me a DM because you are not a subscriber ?

Roy Howland Have a look on the label, it's usually on exterior lhs, and / or inside cover.
It'll tell you what coolant gas is used, if it's a B2200, it'll probably be C407R which is now prohibited from use and I understand gases currently permitted are not suitable for use in this unit ☹️

BOC won't sell it to you unless you have an account. That and F-Gas

That and they are the most expensive in the business.

We used to use them for OFN and Oxygen, but the costs are eye watering. They charge you to collect the gas if you don't get it delivered which is also a rocking fortune. Then they charge you for the gases, fair enough. But their monthly bottle rentals are crazy.

We now use an alternative company that charge a one off bottle fee, plus the gas. No rental charges, keep as long as you like. take the empty back and simply pay for the gas.

My point was that the original poster said that R407c was now prohibited and could lead to someone making decisions based on this fact alone.

Loads of R407c gas on eBay and self refill kits. I’ve seen a video on YouTube showing you how to add taps to the system so it can be regassed.

Taps or LTV’s (line tap valves) are prone to leaking too. We don’t use them other than for gauge analytics.

Fine for DIY. But messing with refrigerant and getting it wrong, you could get your fingers burnt.

Yes correct but all in saying is they can be gassed back up if needs be and I’ll not be touching it that’s for sure.
