Weston Trawick's guys are awesome!
Bought my Generac from Weston Trawick and they set me up and tested it. 2 days later power went out for 6 hours. Cranked right up! Thank you, Weston Trawick,!
Bad Features I am an Electrical Contractor
I had Purchased This Unit From CED in Hudson on May 14th 2025. Brought it home Installed proper gas and oil Tried to start it it started for a few seconds so I called Generac They told me to take it to be serviced at MacDaddy's Small engine repair in Land O lakes. They still have it there, It had faulty Parts. Your Company would not replace it.
Super impressed
Was part of the "Bomb Cyclone" that hit the PNW on 11/19/24 and lost all power. After two days, we decided to invest in a generator knowing that this could happen again. The set-up was easy, the controls were well labeled, the starting process was explained with help from stickers located above the fuel line and choke lever (but make sure to read the manual first). The unit started with ease and ran for 4 days straight as we were out 6 days total. I was able to plug in the chest freezer, mini fridge, floor heater, lights, cable with TV, recliners, computer, and was also able to charge phones and flashlight batteries. This is my first generator ever and now wondering why we didn't purchase sooner. Would have made those first two days way more tolerabe! As a suggestion, even though the unit comes with a 20' heavy duty cord with 3-plug-in capabilities, I stronly suggest having a 50' or 100' equivalent heavy gauge (12g minimum suggested) to run from the unit into the house. If there was one thing I would try and change, it would be the noise output which I know accompanies all generators and just something you and the neighbors will have to deal with unless you devise something that dappens the noise without hindering the exhaust in any way. Overall, I'm super impressed and would recommend to family and friends without hesitation.
