Bought 8 months ago. Equipment has not worked properly since day one. Four seasons is horrible company. They have very poor follow up. Horrible experience.

Had this installed a month ago. Have a big test coming up this weekend with a hurricane coming in. Keeping my fingers crossed that the generator will perform as it should.

I glad I bought this unit but when the weather got real cold it failed to start. It has run for a couple of days when hydro lines were down so it is very useful. We live in an area of the country where there are frequent power outages.

We no longer have to worry about how long the power goes out which has been happening more often over the past 2 years with more trees falling on the power lines.

The Generac has already run three times, and each time it worked exactly as expected. It gives our family peace of mind knowing we have reliable backup power whenever we need it. We are very satisfied with our purchase and the confidence it provides during power outages.

A little over a year and several long power outages, this thing has performed flawlessly. There are 2 homes in our area that stay lit up during an outage, my mom's and mine. It was comforting to see her Christmas lights on when the neighborhood was dark.

My new whole house generator was installed a month ago. After living with frequent power outage for years, we decided to invest in a new whole house generator to be able to stop rolling out the portable generator, extension cords, flashlights and worrying about food in refrigerator and freezer. All that concern was in the past now that we invested in our new generator. The generator performed properly on the power outage test after the installation though we have now discovered that the power outage test should have been run for a longer time period, The weekly 5 min tests performed since installation ran properly but on the first power outage, the generator would not operate properly to provide power for the house requiring immediate service. During this first power outage, the generator ran for 7-8 minutes and shut down. My installer came that evening, did some troubleshooting and eventually replaced the brand new Generac air filter with a new air filter (not Generac) as the generator would not run properly with the OEM supplied air filter. The engine would run ok for the first few minutes but then would begin to surge after 6-7 minutes and begin to exhaust what smelled like un-combusted natural gas. The exhaust pipe was getting hot enough to see the metal change temperature before the engine would shut down. The ecode was 5101 Engine speed. Its great that the design of the generator engine has the capability to protect itself and protect homeowners if the generator is exhausting un-combusted natural gas near your home. It is not great that Generac is selling generators with questionable quality air filters. Folks that I know who have owned Generac generators for years, all provide solid reports about the performance of the Generac brand. Keep the oil changed regularly with premium oil, use a premium oil filter, a premium air filter, verify oil level especially after or during extended power outages and check on the battery; by doing these things your generator will provide years of service for your home. Feedback is that Generac knows that there is a quality issue with their supplied air filter. If you purchased a new large whole house generator, mine is the 22KW model, check your air filter. If its a Generac brand air filter, model number 0J8478 with labeling indicating Flame Retardant, do yourself a favor and replace it with a premium air filter. This air filter may be or is starving the engine by not allowing sufficient air flow into the engine. My brand new generator with the factory installed air filter restricted air flow sufficiently to make the exhaust pipe hot enough to begin to glow and fortunately shut the engine down. If you have the above air filter, replace it with a quality air filter to help ensure your generator is operating properly. Will have to wait and experience the next months and years to see how my generator performs. Initial experience was not positive but Generac is known to be a good brand. Unfortunately, it seems that there is a quality control issue with this air filter. Hope that the remainder of the generator lives up to the solid Generac reputation.

Bought for insurance not truly figuring to need. Seriously, 29 days after installation a tornado goes through and breaks off power poles!!! Our home was a shining beacon in the neighborhood! So grateful to be able to care for others with lodging, food prep, electric charging and cooling in the terribly hot and humid days. Grateful beyond what we can express!!!! So glad we did this and just in the nick of time!!!!

Generac has reputation of general quality at reasonable price. I do not like the mobil app being only control you have of generator. Much more prefer the on unit control screen. Design and appearance is good, but wiring entry should have more options than the one entry point. One eyesore is the gas regulator having to be 5' from generator. This is requested by Generac not local jurisdiction inspection. This also adds to possibilities of damage to gas line which outweigh the gain of safety by placing that far away.

The unit was in the house I purchased and was less than five years old. Between years six and eight years old I've had to replace control board and the starter along with expected batteries. Working in Municipal Government for thirty five years responsible for maintaining fifteen generators of varying sizes I feel this is a high degree of failure
