We also want to know how to choose the size for a normal sized house with air conditioning running most of the time in summer.

There are many choices of generators that operate on Nat. Gas. First you must decide what appliances that must be on the generator. Add up all the nameplate ratings of these loads and any other lighting, computers etc. Motor loads generally draw up to 10 times the nameplate rating upon startup, so allow for this by doubling these loads and add to the total. Most generators in the 12KW range and up will have the transfer switch, time clock for exercise, auto start and other features. A weather proof enclosure or a fire proof shed is needed, along with two conduits from main panel to transfer switch. This generally is not something the average homeowner can do. Most electricians should be able to complete this for you.
