I would think it is, First off, they have to remove the refrigerant in the system. fit new compressor, it should then be vacuumed for a time , to get rid of any moisture in the system, Then it has to be regassed, to correct level. They should be able to reuse the refrigerant. Oil also needs to be added, Just looked up the price of a similar type compressor, as I do not have your model No. £132 plus delivery. So with that and all the work. Would not think you would be able to get much cheaper. To do it yourself, Add about £2000 minimum, for the equipment. Then add another £4000-5000 for the training to F-gas cat1, Which you must be by law to work on the refrigerant side of them. I know, I have just done it myself, But I am self employed engineer.
