Reliable electrician, hvac and flooring contractors Northern NJ

Hi, 

I am looking for references on this board for quality contractors in northern nj (I live in Bayonne, but near Jersey City). Anyone have solid, reliable contractors they are willing to recommend? Here is some of the initial work I want to do :

* install central ac

* replace basement flooring 

* reglaze wood flooring 

* replace doors

* remove trash

* general handyman work 

Thanks!
