Anderson Power Services

★★★★★4.8(151 reviews)
92Score

Anderson Power Services has earned a strong 4.8-star rating from 151 reviews. Customers appreciate their competitive pricing and efficient installations. This company is ideal for budget-conscious homeowners wanting quality service. However, with fewer reviews than the top pick, some may find them less proven. That is a substantial body of feedback for a local operator, enough to trust the rating rather than credit a lucky streak. Most of what reviewers hire it for is budget-conscious homeowners. It serves Greenville, SC and nearby regions, with $1,500 to $4,000 pricing, and the honest trade-offs are smaller review base and limited brand selection compared to top competitor.

Pros

  • Competitive pricing
  • Efficient installation process
  • Friendly staff

Cons

  • Smaller review base
  • Limited brand selection compared to top competitor

89Score

Carolina Power Solutions, LLC holds a commendable 4.9-star rating from 14 reviews. Customers often highlight their personalized service and attention to detail. They are a good choice for those wanting a tailored installation experience. However, their limited number of reviews makes them promising but unproven. The review base is still thin, so we read the rating as promising rather than proven and weighted it accordingly. Most of what reviewers hire it for is customers seeking personalized service. It serves Greenville, SC, with $1,800 to $4,500 pricing, and the honest trade-offs are thin review base and limited operational history.
