"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."
