I replaced the original 60 amp service in 2008 with a 200, and brought
this grandfathered 2970 house service up to code, doing all the internal
work myself. I have a big ups running everything but the lights and
printers in this room, got rid of the copper telephone because the cable
was 70 years old, 50 pair paper insulated cable they would not keep
working for a week at a time, so after 5 months of that I voted with my
wallet and hooked all that up to the cable system. I must have done
something right, I have not even blown a ccfl light bulb since and it
all runs 24/7/365.25.
You can have incoming-mains overvoltage protection installed to
provide a base level of protection for everything electrical against a
mains overvoltage (but generally not other types of power
fluctuations). It's not even all that expensive, or at least wasn't
some years ago. Consider asking your electrician what options would be
available in your particular situation and for a cost estimate or
quote.
Especially if you are in an area that frequently gets lightning, it
_might_ help the UPS last longer, too, since its protective circuitry
then doesn't need to take the brunt of the voltage spike after that is
already well inside your home with all the associated risks.
It's worth mentioning that with a good UPS you get power-conditioning,
not just filtering and over/under-voltage protection. That can extend
the lifetime of any electric motor or other device using the conditioned
power. The UPS emits a controlled waveform beyond what your utility can
provide.
And numerous datacenters have begun using DC-powered racks. Less power
loss in the individual transformers and motors in each racked server,
less heat to be expelled.
