Hi, my built-in fridge-freezer is beyond repair and I was told that this was because there was no ventilation installed. I am looking for a replacement now and I am wondering if there are any retailers that will provide full installation service if I buy the fridge-freezer from them? (i.e. install ventilation, fix the appliance doors to the built-in unit etc.). Or do retailers tend not to provide such extra services? Is the only option to buy a fridge-freezer first and then contact an electrical appliance engineer separately to sort out the installation? Any advice or suggestions would be appreciated. Thanks.
