Rated 5 out of 5 by from Great Install and Product Excellent experience with Specialized Power Service, Inc.. We shopped around for estimates for Generators. SPS provided a detailed estimate vs an invoice with one final estimate price with competitive pricing. It was nice to see how the entire cost of the estimate adds up. The communication was the best that I have had from any contractor. Nikki at the office will send out a detailed time line for install, including the pad or base for the generator, gas lines and then install of the generator itself. She also schedules the inspections and informs the home owner of the inspection schedule. I have never had anything run as smooth as this install. Scott the owner is very professional and informative and answered all our questions along the way. I wish all contractors were this easy to work with. We now have the peace of mind that in a power outage we have a full house generator. No more running around buying ice and putting everything in coolers or worse having to stay at a hotel during a several day outage. We took the leap and so happy we did.

Rated 5 out of 5 by from Thankful for my Stand y Generator Chief’s Electrical Plus did a great job with the installation in spite of our county’s issues with the installation process. He/they did a good job with the install and it looks amazing. We highly recommend this company. Mr Love communicated with us every step of the way so we were kept informed during the process. We have had it work while power was out and we’re cozy during the cold weather!

Rated 5 out of 5 by from Top notch This generator and transfer switch are great. I purchased and installed myself. The guidance in the manuals is great. Granted, you do need to know how to do electrical work and gas piping correctly and safely. I called for assistance getting it connected to wifi and the representative was very helpful and polite. The system then started up and functions perfectly. Very satisfied.

Rated 5 out of 5 by from This product is well worth the money Mine was just installed today and so far the entire process was great. The staff at Absolute Sola & Energy Solutions in Hummelstown PA are the best. They were quick to respond and when speaking to the office staff on the phone they are very helpful and pleasant. The installation was a breeze, the installers were very professional and did a great job at explaining everything to me. I highly recommend this team and unit for peace of mind. David

Rated 3 out of 5 by from Good generator but disappointed in quality The purchase, installation and certified startup went very well. The first year of service with five hours of run time required three warranty visits by the certified startup company. The first warranty call was due to the generator over cranking and loose bolts on the frame. The certified startup company addressed these issues quickly. The second warranty call was due to an oil leak. The certified startup company found loose hose connections around the engine and cooler. They replaced the factory clamps with adjustable clamps. Once again they did a great job. The third warranty call was due to another oil leak. This time the certified startup company found the front engine seal leaking. This was a major repair as they had to remove the entire end of the generator. Once again, they did a great job. At this point, I started asking questions about the warranty and extended warranties. I was given the warranty registration details from the certified startup company and was told to call Generac. I called the main number and was told to call the power group as they handled extended warranties. I called the power group and was told my generator was not registered to call the main number again. I called the main number again and they stated the generator was registered and to call the power group again. Well after many calls I realized I could not fix their departmental communication problem and gave up. I do believe Generac is a good company which is why I still recommended the product. However, I would highly recommend reviewing other manufacturers offers, as I unfortunately found afterwards that they have better warranties and very good reviews as well.

Rated 5 out of 5 by from Great product & service! We chose Generac because our research told us that their generators were the best in the business. We chose Oklahoma Generator & Larrison Electric because our research told us that they were the best installers in our area. From start to finish we were totally satisfied with both the product & the installation! I would highly recommend Generac generators, Oklahoma Generator & Larrison to anyone wanting the best in home generators.

Rated 5 out of 5 by from The 24kw generator The most prominent feature of our 24kw generator is the peace of mind that it carries. Had ours installed by Mr. Watts Electrical following the recent cold snap here in North Texas. They had units in stock where other installers were 4-7 months out. The installation was done by one of Mr. Watts Electrical team of professional plumbers and electricians. Both my wife and I are pleased and highly recommend this product.
