Hi Pato,

Its not just a matter of cleaning and vacing the filters and evaportor.

1.Remove the Filters
2.Unclip the louvers
3. Unclips the slated fins
4.Vacuum the evaportor coil and machine
5.The evaportor coils to be sprayed with coil cleaner and bacteria remover, this should be sprayed on quite heavy.
6.A acid drain cleaner needs to be applied to the drain pan (250ml) and left for 10 mins and then flushed with clean water.
7.Spary the coil fan with plastic fan cleaner and wipe dry
8. Wash fiters and dry, refit filters and all other fittings.
9.Go to the outdoor compressor, connect up your manifold gauges to check working pressures.
10.Run machine on cooling for 15 mins
11. Your disharge pressure should be between 7-9 bar, this is for R410a refrigerant and you will have to check a comparter chart for different refrigerant.
12. Run the system on heat for 15 mins and the pressure should run on 31-35 bar.
13. if pressures are low refrigerant needs to be weighed in.

This 90% of the serice done

Agreed but do they do that? I have my doubts going on past experiences, Portuguese talk a good game and that's about it.
