We hired Mitch Mountney's firm Powerhouse Generators to install a whole home generator for us. His company's address was listed as being in Estero, FL (we live in Naples). We've done our best to hire locally for accountability, primarily, as well as supporting local businesses. The address was of his family member, so he was not actually here to personally account for his work (*note: make sure your "local" contractor is local, put eyes on their storefront*). We gave him $19000 for the job (*note : NEVER give any body more than half down*) - he hired subcontractors in the area, which was okay for the most part. However, for the last step of installation/activation, he hired a Generac tech (our box is a Kohler) who attempted to install an ill-fitting Generac battery into the generator, causing significant damage to the to the inner housing. THIS ACT VOIDED ANY WARRANTY TO WHICH WE WERE ENTITLED. The tech, not knowing Kohler products, also failed to install plugcaps on two small openings in the bottom rear of the generator; this allowed for palm rats to invade and chew up the bottom wiring and insulation in the box. When the tech left, he left copies of the operating manual along with an ethernet connector and the plugcaps which should've been installed. (*note: if the tech hands you "extra parts" not knowing what they're for, you might want to check - quickly). If the plugcaps had been properly installed, it may have been awhile before any other techs would've needed to open up the box to service - only then would the battery install damage would've been discovered, again, no warranty (*note: when I spoke with the tech on the phone, he said that Generacs were "easy" to service, and Kohlers weren"t - if someone is having difficulty with installation, you might want to find out why - quickly*). With 0.1 hours (yes, SIX WHOLE MINUTES) on our generator that we paid an additional fee on at the "end" of the job - total cost: $26,000, it was toast... We hired our local Kohler tech to remove the old box and install a new one; the added cost is another $9000. So, some times, with the best of intent, things go wrong. MITCH MOUNTNEY HAS NOT RETURNED ANY CALLS from me, nor has his operation director Amanda Jonatzke. Read that again: NO ACCOUNTABILITY, no responsibility taken, at all. His operation no longer lists a Florida address, and apparently Powerhouse is now "Oakland County Generators", just fyi. Our Kohler tech has serviced other generators down here that have had issues with the quality of Mitch's supervision and integrity. If I could give this clown zero stars, I would - HE DIDN"T FINISH THE JOB.
