Started out great, not so good now

Had been in the process to get a 22KW installed and then Ida hit. Power went out Sunday evening about 5:30 on 8/29. We were running the house on a 17.5 KW portable Generac but getting fuel had become an issue. Our dealer texted me the following Thursday AM about 6:30 and asked if we were still without power. I replied yes and they showed up a couple of hours later to install the unit. 5 hours later we were up and running. Everything went well until Sat AM when the unit shut down. I went to check it and the enclosure was full of oil that had leaked out of somewhere. I refilled it and got it running but it continued loosing oil. We got power back on Sunday evening. Unit now goes into over start shut down. Dealer came and did the first service but the unit still will not start and run. We suspect it has a bad circuit board so am waiting on that so we can get it started to find out where the oil is coming from. We suspect it is a rear seal since oil is coming from the exhaust end. Service tech also noted metal shavings in the oil. Bottom line is we are still without standby protection.

Great product and installation

Our installer was Lawrence Levy (A Wiring Man) and he did a very professional and high-quality job. He integrated the equipment with our existing wiring and panels and fixed anticipated future problems. It was all done and tested in 1 day. He answered all our questions and is quite a personable guy. The gear all has a clean look and looks like it came with house. We installed the Generac app and it works well. I especially like the regular automatic maintenance testing. We are quite happy and now do not have to worry about highly likely multiple summer blackouts.

This product provides full coverage for senior citizens and great peace of mind

The system was installed very professionally, and at a pretty reasonable price. As a senior couple, my wife and I wanted safety and quick response in the event of a power outage. My wife is on oxygen and I have limited mobility in my 80’s. The system provided great peace of mind and no complicated process to learn. It does everything automatically. I have had the system 2 months and have already been needed twice. The system kicked on quickly and shut off without any work for me to do.

I feel so much more secure with my Generac

I hate losing electrical power — no heat or cooling, no lights, no Internet. In the past, I’ve lived in areas where power could go off for days. No more! I had a 22 kw Generac installed a year ago. The peace of mind it provides is priceless. When the lights go out, I count to 6, and I hear the generator start. Then I count to 15, and the lights come on. During the last year, we’ve had four multi-hour power outages. The Generac has never failed: Within 25 seconds, power is back on every time. I will never live without a whole home generator again.

Power outtage answer

My house is all electric and for several years I've gotten by with a portable generator, but it couldn't power my entire house. The Generac Guardian 22kw is just the thing for whole house electric power. Installation took place over 5 days, pour the pad (over weekend to set) place generator & 250 gallon tank, then transfer switch install. Finally the battery was installed and unit started. My Heat Pump was turned on then; both heat & air, worked perfectly. Electric hot water tank operates normally under the generator power along with all my other appliances. Weekly 5 minute test run was then programmed; the generator started & stopped on time. Completely satisfied .

22kW is very noisy

At maximum load, the unit is very noisy. In side the house -- not problem. Outside -- big problem. We are sure I will get complaints. A fence company will be contacted with sound controlling elements to direct the noise upward to the sky, if possible. Otherwise the unit works correctly. The voltage is not at 120 VAC, but does get to 117VAC. I am not sure if that will be a problem. We can not run our electric wall oven or cloths dryer. The 5 ton AC will run with no problem, all light (all plugs), on-demand hot water heater and the two refrigerators work well. We have not tested our furnace yet. Transfer switch works quickly and power is back on in about a minute. I suggest dedicated, non-GFI for freezers and refrigerator -- when they trip, the Generac can not provide power to GFIs.

22kw Generator

Spring Generator did an excellent job installing our 22kw whole house Generac generator. We were pleased with their company. However, when they first started the generator, the engine malfunctioned and blew a hole in the case blowing out the oil. The unit had to be removed and taken back to the shop. Generac took a few weeks to supply another engine to Spring Generator so they could re-assemble it. It is working fine now but will need to watch over time.

Installed by Longs Airconditioning Company of Avon Park Florida. I couldn’t be happier.

Four words to describe Kenney Long: Honest, professional, personable, competent. His crew is well trained, friendly and hardworking men. Except for the beautiful Generac Generator, You would never know they were here. I highly recommend Long’s Air Conditioning of Avon Park Florida and Generac whole home generators.

We love love love our Generac

We live near the Gulf of Mexico & now have peace of mind that we will not have to leave our home during a power outage. Hurricane season is no longer a deep concern. Wish more people knew about this wonderful produce with all its features. Thank You Generac!!!
