What an AMC actually is
An annual maintenance contract is a fixed yearly price for a defined set of visits and a defined level of cover for things that go wrong.
It normally includes scheduled servicing, usually of the air conditioning and sometimes of other systems, plus a number of call outs for faults.
What is covered on those call outs varies. Labour is almost always included. Small parts often are. Large parts usually are not.
So the trade is straightforward. You pay a known amount instead of an unknown one, and in exchange the provider takes the risk of ordinary faults.
What it is not is insurance against everything. A compressor failing is generally outside any normal contract.
