Excellent performance but uses A LOT of oil

Had unit installed May 2018 so we would have A/C in the event of a hurricane related power outage similar to outage during Hurricane Irma in 2017 when we were 5 days without power. As of June 2022 annual service the unit had only 25.5 hrs on meter. So until September 28, 2022 when Hurricane Ian hit and we lost power we had no experience with extended run time. Owner's manual indicated need to check oil frequently as it might need oil added. I had assumed after June 2022 service the unit would have enough oil to run safely for a minimum of 24 hours without getting a low oil warning. Due to the rain and wind it was not possible check the oil and at 27 hrs (9/29/22) the unit stopped under low oil warning. I had only 2 quarts of the required oil. A check 12 hrs later indicated it had gone through a quart so I had to reduce load until I could get more oil on 9/30/22. I was not pleased that after 39 hr run time I had to severely reduce the load and go without A/C- the main reason I bought the unit for. The owner's manual NEEDS to indicate the potential amount the generator may use during 12 hr continuous usage so people have an appropriate amount of oil on hand. I had no idea the unit would use 2 quarts a day. In the future I will have at least 10 quarts of oil on hand. Other than this annoying lesson learned I am happy with the unit.

Great purchase!!

If you’ve been thinking about purchasing a Generac for your home, I would highly recommend it! The first time we lost power, I knew then, that my families comfort was worth every penny that my Generac cost! We still had satellite service and internet! Heat, hot water.......

Love the cold weather option and sleek look of the unit.

The Spring City Electric installation crew did an outstanding job. They were very professional in their approach and kept me informed throughout the installation process. The entire process took less than a day to install. Now I'm ready to tackle my first power outage! :)

Game Changer

Had this generator installed in September, and it has already provided power to our home during 2 brief blackouts. No more stress about not being able to get water from our well or the furnace not heating our home when it's cold! Generator starts within 5 seconds of the power going out, and is providing power to the entire house within 20 seconds. Glad we purchased it.

Peace of Mind

My Generac was just installed on 1/13/2022. I have not had a power outage since then. It has run its Self Test as scheduled. I now have peace of mind. I live in a suburb of New Orleans and lose power due to hurricanes and other storms. Just lately, we had to evacuate for Hurricane Ida. We were away from home for a week hoping that we would see power restored. When we returned home we did not have power yet. The house was very hot and it was another ten days before power was restored. It would have been great to have my Generac at that time. Hopefully future hurricanes will be easier to deal with.

Pleased with New Unit Based on Initial Performance/Quality

Based on power outage testing performed after installation by our installer I was impressed by what the unit does, but more impressed with how quickly it does it. Initial quality seems very good, and the unit design is attractive. I'm almost excited for our first real power outage.

Great installation

Fine crew installed my generac today. Tapped into a natural gas line, put in the transfer panel, put the unit on the pad and hooked it up. Tested fine! Almost looking forward to a power outage. Real peace of mind, winter or summer, We will have heat in the cold up here in upstate NY and AC in the summer. No worry about food spoiling and having to light candles and sitting around unable to even read a book. We opted to have the whole house and out buildings covered. I can even go out to my garage to work!

Dissatisfied

It is hard to review a product that was installed on April 4, 2023 and still not operational. There have been multiple delays (installation, correcting gas line, failing electrical inspection and a faulty part). In addition, they get in no hurry to address these problems with 2 to 3 weeks in between each issue. 2 1/2 months later we have what is essentially a very expensive lawn ornament. I am hoping that we might have a working generator by no later than fall at this rate. Very frustrated and completely unsatisfied with not only Generac themselves, but their approved installer as well

Warranty Issues

Bought our 16kw natural gas unit six years back. The only times it ran was during short power outages lasting a few days and weekly runs. Hurricane Ida hit and we thought things were under control. Six hours into the storm and it shut down permanently. The next day I found the cover missing which allowed rain to get into the generator itself shorting everything out. Calling Generac we were told it was an act of God and our extended warranty would NOT cover it. Upon further evaluation we determined it was what I consider a manufacturers defective method of bonding the top to the subframe. The top or rather frame while locked on both sides, remained in place while the lid, held in place with sticky foam tape flew off. The tape didn't even leave residue on the lid. We just got the insurance company to agree on replacing it since Generac stands by their decision. We had to go with Generac again, but I will drill holes and bolt the lid in place this time. So a word of caution to everyone, BOLT THOSE LIDS TO THE SUBFRAME. I hope the business that installed the new unit can file a claim for the techs time to install it since insurance merely paid for the new generator but not installation. The techs did awesome work and even corrected a few issues from the first install.

Peace of Mind / Quality / Convenience

Living in the heartland, "...where the wind comes sweeping down the plain...", and the ever present possibility of bitter cold and ice storms in the winter, the threat of power outages is high. We experience a mean average of 5-7 outages a year. Those outages can last minutes to days, anecdotally, 2-4 hours in my experience. No more portable gensets, no more stored gasoline, no more extension cords and inlet boxes, no more breakers and interlocks. No more fighting the elements to get the power back on. Generac does all that automatically and in about 15-20 seconds. That friends, is peace of mind!
