Old Nj Powergrid
Comment:
We live at the end of a power-grid. After the freak snowstorm in Oct 2011 we were out for 6 days. We live in an area where wells for water are common. House was completely unlivable. We ordered the Kohler 20kw after a lot of research. My dad has had a Kohler 12kw for over 10 years without issue. He does the maintenance himself. We had it installed by a local electrician who was also a Kohler distributor.<br />When Sandy hit NJ in Oct 2012 this Kohler powered our entire home for 8 days. We had a dozen friends and relatives moved in here and except for giving the generator a rest and checking the oil every 36 hours, it ran flawlessly the entire time. Powered the furnace, well, washer, dryer and every light in the house. We had a steady stream of friends from all over town stopping by to charge their phones and grab a hot shower. Best improvement we've ever made to our home! And I'm sure my neighbors agree.

Comment:
We bought our Kohler 14kw LPG standby unit on line in 2012 and did a major portion of the installation ourselves. The critical electrical hook up was performed by a master electrician. The unit has performed without a hitch since September 2012. This includes starting in subzero weather, although I'm installing the recommended carburetor heater this spring based on OEM feedback. As with most items of this kind, once you install them you don't have an emergency to prove their worth. The once a week exercise, however, lets you know the functionality of the system is performing as designed or not, and it's fully automatic. I highly recommend the Kohler systems to anyone in remote areas, where you might be without power for extended periods.

HIGH QUALITY AND EXPENSIVE MAINTENANCE

Comment:
Kohler is high quality and the buyer pays for that. Remember these are standby generators for safe use in an emergency, for basics. <br /><br />When shopping for a generator it was difficult getting concise info upfront about the Kohler warranty's interplay with Kohler's annual $325, 40 step, one hour service call (i.e., for a 20 KW gas unit). The Kohler dealer/installer will do it at 6 months, then annually thereafter, and charge the expensive fee each time. <br /><br />A routine, annual 40 step inspection suggests a lot of things can go wrong, but how likely? we don't know. And there is a black box in the unit which reports to the servicer's computer software during inspection. Can any of this data be monitored by the owner, instead, and would that satisfy warranty requirements? Can the owner do any other maintenance (eg., oil change, air filter, etc.)? Are there warranty-accepted servicers nearby other than the dealer/installer, and which may be less expensive? <br /><br />Compare these costs with other manufacturers and the quality of their units. During a 5 year Kohler warranty (20 KW unit) the annual inspections would total about $1600 -- of course, an owner would continue inspections therefter regardless. What about such costs at the other brands?<br /><br />The best measure of whatever maintenance any unit really needs would be what's required by the warranty, since then the manufacturer is on the hook for repairs.
