Posted by: @editorAs part of your services, did they check the refrigerant levels?
I don't think that checking refrigerant levels is common practice for annual servicing but given how important it is to the heat pump, I wonder why it's not checked.
it’s very difficult to measure the charge, it is weighed in when filled at the factory. And there aren’t anywhere near enough f gas qualified technicians. That’s why everyone fits monoblocs.

I remember watching an American video some time ago, where the Technician measured either temperatures, pressures or both on the heat pump unit, that indicated if there was sufficient refrigerant gas in the system.
Well, these days practically any garage can fill air conditioners in cars. Therefore drain, measure and fill gas in them.
It's surely not that complicated.

Yea, you can do it by measuring the temps and pressures at certain points of the system. Then you calculate what the correct values would be for the factory gas charge. Or at least I think that’s what you do.

Hi,
Im looking to have my ASHP serviced and looking around for prices. Ive been quoted £250 (plus vat) for a service. Does that sound about average?
Also, how long are Mitsubishi ASHP parts warranty for? 5 years?
Thanks
@tufty, have a look above in this thread. Your price is about average for a one-off visit. Warranties on heat pumps aren’t clear - other Ecodan owners may have insights.

My standard Ecodan warranty was 3 years from commissioning date and installer suggested I buy extended warranty (which I did) to cover 7 years
@hughf refrigerant charge quantity is critical. The best place to charge the unit is in the factory when built, where equipment is calibrated and controlled and very thorough leak detection can be carried out prior to charging. Monoblocs have a very small refrigerant quantity requirement and, because they are outside, flammable refrigerants such as R290 propane can be used rather than R32. Many ASHP service engineers who have transitioned from the Gas Safe fired boiler side of the heating industry won't be F-Gas registered, so cannot touch a monobloc refrigeration circuit. Every time a refrigerant manifold is connected to the HP and LP sides, and then disconnected, there's a slight refrigerant vapour loss.
@allyfish your point being?

Completely different set of regulations covering the automotive application of F-gas…. So different that you don’t need to be f-gas registered to work on automotive AC systems.

Mine is 5 years if serviced every year.
@mjr I dont suppose you know if there is an online record anywhere of the service history? My (now ex!) partner was responsible for getting the ASHP serviced (while I focused on everything else involving a full property renovation).
I cant find a 'commissioning document', but I do have a Handover document, although no mention of service history.
I guess - if I cant find a record of annual services performed - it will void my Mitsubishi warrantee. Will it also impact on my RHI payments? Im really concerned now.
