"Kope Electric just finished installing a Generac generator at my house and their work was top notch. They actually got me in their schedule 1 week early and finished as timely as they said they would. I highly recommend them to anyone interested in a generator."

"Cynthia and the team at Ryland were fantastic to work with. I called them the morning after losing power in a snowstorm to see if they could install a 30AMP/240VAC inlet plug on my house to run the generator through. Not only did they take the job, but Cynthia spent the next day trying to help me find the very hard to find parts I needed during the storm. She really went above and beyond for a customer she has never met and has never worked with before. Once I had everything I needed, they were at my house within a couple of hours and had me set up and power back on in my house. The work was done quickly and professional and the price was great. Jay and Carlos were friendly, walked me through what they had done and how everything worked. I will definitely be using Ryland again. Great experience all the way around in a difficult situation."

"We live in areas where power outages happens a few times a year. Last one lasted 3 days and we had to to stay in hotels. We all thought getting power generators and hooking up is one of the toughest project for home. Brian and Ryan made it so easy for us. First Brian came to our house at 8am before I head to work, he examined our electrical system and explained to us what need to be done and what we need to get. Then we picked the generator, ordered from amazon and delivered to our house. Lastly Brian’s team took care the rest with reasonable rate and walk through everything with us thoroughly after installation. Awesome service and from now on we will call B-Tec for all our electrical need. Thanks Brian and Ryan."
