"Hired “Power Up” to refit our electrical panel and install an outside connecting plug to run a new portable electric generator. Jeff came out and spent time to evaluate and discuss our needs. He was consultative throughout the whole process. Lisa was responsible for arranging installation and paperwork and was very responsive to inquiries as well as reaching out to confirm things were moving forward. Justin was our installer and he knew his stuff. Very friendly and completed the work on time and as expected. Great experience working with “Power Up.”"
