The company that built/installed our central heating is offering a contract of yearly servicing for 233eur/yr. We live in a new built from 2019.
They're saying the obvious vendor things, the system will remain efficient saving you money long term, safety, blabla.
I'm all in favor of servicing staff before they break rather than after, but hey it seems overpriced, more than 40% of our yearly gas bill.
Opinions?
