Buyer Beware
A word of caution to Costco shoppers. Costco is selling a Honeywell generator and it seems like a good price, however the transfer switch that they sell with it will not work for 95% of the homes in our area. You would have to buy the correct transfer switch which will set you back almost another $1,000. Even then the generator is undersized for the application.
If you have questions about generators, ask us before you buy.
