I agree that Honda is the best. Would suggest getting one in the 5000v - 10,000v range since refrig. and freezers use alot of juice and you would still have enough for water pump, some lights, TV, computer, etc. You may also want to look into something called a "transfer switch" that will allow you to connect your generator into the circuits of your house thus avoiding the use of dangerous extension cords.
