Fast installation timeframe
If maintenance person had reconnected 2 wires after cleaning the coil, my current air conditioner would have still been working and I would not have ordered a new one. (Found when installing the new one.) However, it was still leaking freon and would need replaced pretty soon anyway, so I am not TOO upset. Just out the $125 for cleaning the coil on the old one that was a useless expense since it never ran again and got replaced.
