If the problem goes all the way back to the electric company's
transformer, then that means that other houses' lights are
dimming every time this guy's air conditioner comes on (since
electric company transformers usually feed more than one
house), which is unacceptable.
In fact, it doesn't require a "jumbo transformer" to feed
enough power to a house that has an air conditioner, it simply
requires a sufficiently large transformer to handle the load.
There are plenty of perfectly normal houses with perfectly
normal transformers and whole-house air conditioners which do
not cause all the lights to dim every time they come on.
It's possible that the developer didn't install enough or
powerful enough transformers. It's also possible that the
developer didn't install a large enough service into the
house. Both of these would be not-surprising ways for the
developer to cut corners to save money, something which
developers love to do. But, as I said before, the OP should
call the developer and tell him to come back and fix it, even
if that means putting in a larger transformer or a larger
