Although I have most of the house on the system, I bought this unit primarily because winter ice issue to deal with almost every year. Prior to getting the generator, I have had varying degrees of sucess with portable generators, with a few times our generator did not even start, and the amount of anxiety wondering what the power out game plan was going to look like in action.

As far as installation goes, most electricians are going to charge anywhere from $500 to $1000 for transfer box, and then the plumber to hook up the gas line. Gas has to be ran to the unit, so unless you have an existing gas line already in place, the plumber has to lay pipe and your natural gas. Total cost for install was just under $1500.

The unit looks great, self tests every week, and providing I maintain the unit, it should last many years

Since it is powered by natural gas, it is relatively quiet to the gasoline powered generators in the neighborhood. It was trouble free and gave very even output no matter what the load was on the unit with its 20 circuits. For a 3000 square foot home, including the pool house / equipment, it powers about 65% of the devices (lights, water pump, heat pump, electronics / tv / satellite ) and makes staying in the home easy while my neighbors either went to hotels or struggled with their portables, refilling their tanks every 6 to 12 hours of use.

I can't give it a five star review yet, as we have just had it installed Nov 11th. It was done by a local electrical company. Installation took all day and they knew what they were doing. First they had to float a serious reinforced concrete slab. .Install a new second electrical box. This had to be outside because our laundry room was too small to accommodate both boxes. They re plumed our gas to the generator. It was running and powering almost the entire house by 6PM. This was on Saturday and on Monday we got our inspections. We started to have a major wind storm
so the electrical company sent someone out that night to turn it on for us and make sure our other pilot lights were lit.
Everyone around us lost power but our little town was spared. The lights flickered but no outage. Wouldn't you know it!
Anyway. The price that you see here, double it. Ours came in at just over $6,000. We now no longer panic when the wind starts to blow.
We live in WA state and are always loosing power. It's well worth the price for the piece of mind.
By the way they will maintain it for you once a year for $275.00. We have a guarantee of five years if we have problems we call them.
That's what I want because I have no idea how to do this. My husband says it's like maintaining a car engine but he said let the expects do it.

As to the generator and the automatic transfer switch which I have received in before the time expected , I feel these will be fine and I will get exactly what I expected. However I feel that you did not complete the order based on information from the advertisement. I have sent you a section of this advertisement so you can better understand why I feel this order is not complete. I believe you need to modify the advertisement so as not to mislead the Amazon customers.
