Factory Assembly Issues

My Guardian 22 KW Standby Generator is deficient in the manufacturing process and Quality Control Inspection and acceptance testing. After installation by a Licensed Electrical and Generac approved installer upon initial startup and testing process the electrical Contractor was unable to get the unit to operate properly. Engine started within seconds of turning on however during the testing process numerous issues occurred resulting in a lengthy run times consuming LP fuel due to numerous electrical connections not being able to remain in place (spade type fitting being the biggest issue resulting in repeated protective covering having to be removed and again excessive time spent as well as excessive fuel burn to identify the issue and multiple locations. Recommend that these spade connections be crimped a bit more to preclude the inadvertent disconnection during shipping and or startup and test in place situations. Other than this inconvenience all went well after corrective action taken and the unit work very well. Just hoping that we will never have to use it...But it is there in case.

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! :)

Great Generator

I bought my Generac in the fall planning for next years hurricane season. But to my surprise, shortly after purchasing, we had an ice storm that knocked out power for days. This kept our house warm, power to our refrigerators/freezers and was very thankful that we purchased when we did. The generator performed flawlessly and have since needed it for 2 other storms that also knocked our power for a few days.

This is a fantastic product!

After considering purchasing a stand-by generator for several years, my research led me to Generac. It is a quality product that requires minimal routine maintenance and provides great peace of mind. I will definitely recommend Generac to my friends and relatives.

Great peace of mind for hurricane seasons as well as ice storms

We had our 22Kw generator installed last fall just in time for hurricane season. The Carolina's get a lot of hurricanes that affect the inland areas as well as the coast. Plus our ice storms cause a lot of power outages. It is really reassuring having the Generac. We can stay cool in the heat and warm when cold.

Tested by Mid Atlantic snow storm of 1/3/2022

Brandon at Powertech in Hollywood MD did our install and he has been great to work with. Two close calls with ice storms last February and the disaster in Texas got our attention and we decided to install backup power. At 76 with COPD I no longer feel up to dragging the 50 year old 4 kW portable Coleman and cables the 100 feet from the shed to the house, opening the breaker to the utility, running the cable through the garage and up the steps to the dryer outlet, and keeping the generator fueled (I did this for a week in the 1990s). Brandon did our install the last week in March. We had a few very short weather related outages over the summer but the Generac didn't have a chance to demonstrate itself until 1/3/2022. We got a bit over a foot of wet heavy snow. It started about 4:30 am. The local utility started to experience outages about 5 am and by 2 pm over 45000 (about 25%) of customers were without power. We lost utility power at 10:52 am. The generator came right up and ran like a champ for the next 23 hours and 57 minutes when we got power back. We didn't realize we were back on the utility power until we got the text message from Generac that our unit was "ready to run" Coincidentally, 10 minutes after that the generator did it's weekly 5 minute exercise run. We lived normally during the outage, were the only house, other than our Amish neighbors, who heat with wood and light with kerosene, with lights. The peak load on the 24 kW Generac was about 16 kW when the outside temperature was about 19 degrees, the water heater was running due to my wife's nightly bath, and the upstairs heatpump came on in resistance heating mode. I have yet to trudge the 100 feet through the snow to the generator to check the oil (the manual specifies doing this daily when the unit is running). BTW, two days after we were restored about 4500 customers of our utility remain to have power restored. The utility is dealing with a herculean task with all the trees, poles, and lines down. We are grateful for the tireless efforts of their crews and their contractors and the crews they have brought in from other nearby utilities to help with restoration. This will be a storm to remember. Getting the Generac was the right thing for us.

Peace of mind!

I decided to get a generator after my husband passed away. We had a gas powered one, but knew I couldn’t start it. Best decision! I was worried about the winter & being in a cold house with my old dog. Possibly snowed in. Well worth it for peace of mind. Installation by Corbin Electric was quick and efficient. Wonderful experience, everyone was so helpful.

No Outage Yet, But Waiting

I live in Texas, and I am sure a lot of you heard about the snow and hard freeze that crippled our power grid. that storm made me, and my wife realize we needed a generator. I had my 24kw installed this past July and I haven't had to use just yet but knowing and having that piece of mind that when an outage does occur, my lights will be on when others won't. And today I just had the GenMon installed today. Having this generator installed was and is a good investment.

Put the test!

We have had our generator for 2 years now. Installed when we built our 5200 sq ft house. It's only been needed for a few small outages lasting no more than an hour. Well, far East TX here had a massive wind storm rip through our area overnight, causing over 200k people to be without electricity for days. A good portion have been restored. We haven't been so lucky because we are so rural. Not to mention upper 90 degree temps, with 99% humidity, and feels like temps over 110 daily! With that being said, we are on day 6 (of many more) of running our Generac. Only shutting it down every 24 hours to cool and check fluids. Now for the goods! It is running 2 HVAC systems, sub zero double fridge, 4 chest freezers, 2 stand up freezers, and 6 ceiling fans consistantly. Not only that, but we can use the microwave, blow dryer, water heater, dishwasher, washer, dryer, ceiling lights, and many more things without it bogging down. Of the two years we have owned this, I am more than impressed, and very thankful we chose to install this on our home. Thank you for creating such a wonderful product!

Peace of mind.

It is a nice feeling now not to have to worry about outages. just too old to fight portable generators and have to find fuel for them. a very nice looking unit, quieter than my old unit. installation was very professional. would highly recommend to anyone.
