DO NOT USE THEM. I will keep this simple and give the facts: - installation has been delayed six months (because employees keep quitting or are fired and because they made mistakes with paperwork and permits) and still isn't complete - installer was a local person they hired with no oversight. I don't even know who they were or if they were qualified. - installation was done wrong with three different issues. Design was changed without authorization, system was not grounded which is a massive fire hazard and insurance liability - my project manager quit and they didn't even tell me - first inspection failed, was told it needs to be reinspected, then that it doesn't need to be reinspected because the county doesn't require it (which is completely wrong)
