More than met our expectations
Small Footprint
Noisier Than I Thought
Best Uses
Backup Medical Devices
We purchased the 7KW model to back up medical devices needed in the home, to power refrigerator and microwave, to power central furnace, to power everything in master bedroom (including TV) and to power a portable air conditioner sized for MBR. (We live in Texas) We had an electrician install it and set it up with an automatic transfer switch. It self tests every week so we know it is working and when we have lost power the generator kicks on about 10 seconds later. It is a little noisier than I thought it would be although not objectionable. (We live in 50 foot lot patio home community) When we built the house we should have had the gas line sized for this extra capacity because every time the generator self tests the pilot light on our gas fireplace goes out. In all, we paid about $3700 for the whole thing including a portable air conditioner – for us an investment well worth it.

Works well, total cost to install high
Easy to use
Total Cost To Install
Best Uses
We were very fortunate to have our 20kw Generac installed about 2 months before Hurricane Sandy. It ran for 11 days straight while our power was out, and needed one oil change during that period. Operationally it was excellent. We found that the total installation cost for this, and any permanent generator in our area, was very high because of required ConEd processes, slab to mount it, etc. The total cost to install was over $20,000. Also, our electrician is a Generac dealer and essentially refused to install at Kohler unit, a situation that we gather is common in our area.
How long have you owned it:
One-to-three months
Bottom Line
Yes, I would recommend this to a friend.
