As i was researching various generators I cam to the conclusion that I should be buying the biggest generator at the best price. that is why I bought the Generac 7043. Essentially I got a 22kW with transfer switch at the same price of the competitors 20kW generators. Received great help on the phone making my selection. Shipped same day that I ordered it.

Enough is enough. Broke down and bought a home standby generator due to the frequent power outages in my neck of the woods. I did a ton of research and hands down Generac was the way to go. Great assistance from the call center at this website. Best price. I would use this website again.

Hurricane Harvey
Hurricane Harvey is on the way. Purchased my Generac 7043 in June. It will certainly be tested in the next few days. At least I prepared for the power outage of Harvey. Good luck fellow Texans.

Love it
First I have to say I had a lot of questions before my purchase of Generac's 22kw home standby generator. AP was very patient with and answered all my questions. I probably called 3 times over a 2 week period. Never a hard sell which I liked. I pulled the trigger and could not be happier that I purchased my generator from this outfit. Arrived in perfect condition and they had the best price I could find. I loved the free shipping and no sales tax aspect.

Great Service
I needed this generator in hurry. I live in Ohio. Ordered in the morning and had it 2 days later. Perfect transaction from my point of vies. Generator works great.

Excellent
Finally got fed up the power outages here in New York. Last outage cost me my finished basement as it flooded when the back up battery system on our sump pump died. I did a lot of research and talked to the people at AP Electric several times before my purchase. I selected the Generac 7043 because I wanted to power up my entire house. AP had the best price and threw in a free battery battery to boot. Arrived in 3 days. Install went off without a hitch. Sleeping better at night. I would recommend both this generator and AP Electric.
