Worse case; back in the day, IBM evolved to board swapping until it was fixed. If it was really fubar, they replaced the whole unit.

It probably depends on what is failing. The circuit boards and communication links can be back doored, but there are also some dangerous high voltage connections, inverters, and transformers, cooling systems, etc. That would need actual electricians. These things are probably more complicated and dangerous than commercial HVAC systems.
