Best insurance you can have

We live in rural Iowa and have lost power several times in the cold winter. If I was home I would drag out the portable generator and after getting it started I plugged in a long drop cord and ran it inside the house and then decided what we needed to run and what we could do without. When it is -10 degrees we need the furnace to run as well as the freezer, refrigerator, TV for updates on the weather etc. That got old after doing it a few times and even worse was if I was not home my wife really had a hard time getting the generator started and everything put together. I saw the commercial on Generac and decided to call. It was the best money I have spent on our home. We had our generator installed last winter. Since then it has been in use several times and just as you are told- the generator comes on automatically after a few seconds and once the power is back on the generator stops. I can't tell you how much this means to my wife when I am not at home. She has nothing to worry about. Everything is done and the generator runs everything in the house. We no longer have to pick what we want to power up and if I am not at home there is peace of mind that everything is ok. When the power goes off in the warmer months we still have air-conditioning and everything else we need. If I had it to do over again the only thing I would change would be to have the generator installed years earlier.

Quick response, noise level could be better

Works excellent! Had two power outages in my new construction home in a remote area of town. Soon as the power went out the generator kicked in without a pause. Our washing machine was running at the time and it didnt even reset itself. Well-built machine and easy enough to maintain. Worked well with my propane energy source. Only wish it could be much quieter.

Reliable and Ready

A boom in the middle of the night signaled that Hurricane Isaac had arrived. Our utility power went out and within 20 seconds my year old generator came on and I smiled. For six days it ran quietly and did the job keeping 9 adults, 4 kids and 7 dogs happy and cool. It ran 4 central A/C units which were electronically controlled so as not to have more than two start up at the same time. Since it is air cooled I shut it down twice for a cool off period. Very pleased.

Well Built, Great Features!!!!!!

After Hurricane Irma, it was time to get stand-by power for our house. The Generac 20 kw unit looks great and looking inside it also looks very well made. We went with the 20 kw unit, the whole house power transfer switch, and the skirt that covers the base of the unit. After the install and operational tests, our generator provider went over it's many features that make it easier to operate and maintain. I can see that the designers at Generac put a lot of thought into their products. Very Impressed!!!!!!

peace of mind

This summer, the weather has been horrendous. Lightning has been a constant threat. Although, we have not had to rely on our generator yet, the knowledge that it will be there for us guarantees much needed peace of mind. Each week, when the ten minute test cuts on, it is music to our ears. After having been without electricity for two weeks during the aftermath of hurricane Sandy, we look at our generator as a life saver.

Peace of mind is priceless

Metro Electric installed our new Generac home generator. After losing power for 8 days over a 90 day period I wanted the peace of mind in knowing I can reliably work from home with power to my entire house. Our generator can handle our 4 bedroom, 4 bathroom, 2 kitchen, 2 laundry room home and detached garage at the flip of a switch and automatically fails over in 45 seconds or less. Living in a rural area means needing electricity for everything: water, light, heat, internet access, etc. I'm very happy with the product, ease of use, value, and our experience with Metro Electric was excellent!

Excellent Product

Although my generator is only a week old, it was called into action during another South Carolina thunderstorm. As the lights flickered, my wife and daughter both asked: Will that generator work???? In just a few seconds, all was well and we were thanking our great provider for doing such a wonderful job for us. As the texts from neighbors rolled in, I was happy to tell them that we were COOL and safe!!!!! The generator is pretty quiet and looks great with its low profile. We are ready for hurricane and thunderstorm season!!!!!

Excellent product for the price.

Purchased this unit to help with winter power outages. Live in a rural area that sometimes takes hours to get electricity up and running. This will ensure heat in the winter and cooling for freezers in the winter. Installation was done in a few hours by and excellent crew and the test run was great. No more blackouts for us.

worry free connectivity

I've had my generator now for over a year and am very satisfied. Although we have not had any significant power losses, the power has gone out several times for a few hours at a time and the generator has performed well. I work shift work and the power losses were at night, so my wife was very happy that she didn't have to lift a finger to get the power back on; the generator auto started and auto transferred to power the whole house. Very satisfied.

I no longer worry about power outages. In fact, I can't wait until we have one.

First of all, the unit looks good. I don't mind having it sitting next to the house. Inside the cabinet, the layout of the engine is well thought out. Maintenance points are convenient. I am quite pleasantly surprised at how quietly it runs. After installation, I forgot to listen for it to see if was "exercising" at the programed time. I had to go outside and feel it to see if it was warm. We decided on the 20kw unit so we could power the entire house without any concerns. I've been without power several times over the last few years, once in the dead of winter, and they were not pleasant experiences. Having this Generac at the ready is a relief.
