Can a power surge damage an AC compressor?
A weak surge can damage an air conditioner’s capacitor (inexpensive) which, if not replaced, will take out the compressor (very expensive) week or months later. For this reason, it’s important to have a tech check your HVAC system if you have any other damaged devices and suspect a power surge.
What do you do if your AC compressor stops working?

Why is my air conditioner compressor not working?
Dirty AC filters and coils are one of the main reasons why your AC compressor stops working. It is because the AC filters are required to pass clean and filtered air. However, if they are dirty, dust and other debris can get to the compressor coil and affect its functioning. Moreover, dirty AC filters also significantly affect the flow of air.

Why is my HVAC unit not turning on?
Your starter relay transfers power from your capacitors to your compressor. If your HVAC will not turn on, but you hear a humming sound from your outdoor unit, it is likely that this is the compressor attempting to access a non-functioning capacitor. Turn your unit off immediately. This can overheat your compressor, causing unit wide damage.
