Just had a combi "serviced" but all the Engineer did was take readings from the flue etc, only part removed was front cover - didnt take anything off or look inside the burner, replace seals or any consumable parts, or vaccuum it out etc which I was under the impression would be done in a service. When I asked about this he said they only need to do that if the readings are out of spec which mine wasnt, told him it had not been looked at for a good while but he wasnt bothered about that.
Is this correct? Seems to me its like taking your car for a service and them just doing an MOT without changing anything such as oil and filters as "its running ok so doesent need it"?
Thanks for your advice - 1st post but been a visitor to the forum for many years
