FWIW, three neighbors have whole house generac installations and have had no problems. I get by with a portable 5500W and it's the second generac I've owned and have nothing but good things to say about their smaller units. One thing I always look at with any "small engine" purchase, is there "reputable" service and parts locally? You don't want to be waiting for service in an ice storm, etc. if it's a two hour drive and they have lots of closer service calls. One "subtlety" of Generac is every small engine shop I've ever seen has a Generac sign up, that only means they can order parts, have they ever worked on one?
