    Received but not installed

    Posted by Ward Dunscomb on Oct 30, 2020

    Ordered and received generator as advertised. Still in the box. Upon receipt of product I
    realized there was no switch box. I contacted AP Electric to ask which switch box would be best for my home. That was 10 days ago and have not heard a peep from anyone. I guess once they had my money, I no longer need their services

    Happy with Generator

    Posted by Brett A. on Oct 09, 2018

    We are pleased with our purchase of Generac's 7042 20kW from AP Electric & Generators. They were helpful in helping us decide what generator to purchase with no pressure. Arrvived quickly and undamaged. Would order from this site again. Local electrician said installation was a snap. Charged us about $2,000 to install and works perfectly in the one brief 2 hour power outage we experienced since it was installed.
