How the score works
Points per factor, out of the 75 we can measure in Cincinnati, scaled to 100.
- 30Rating
- 15Reviews
- 20Years
- 6Services
- 4Warranty
The full method
Google rating is blended toward 4.3 stars with 25 imaginary reviews (30 points), then Google review count (15), years in business (20), the water heater services it lists (6) and a published written warranty (4). A company with no Google listing gets 0 for both Google factors. A company is listed only if at least 90% of those points come from records we checked, it scores at least 60, and any plumbing license its state requires is confirmed on the public lookup. A factor we could not check after two tries is estimated at the 25th percentile for Cincinnati and marked as an estimate. BBB grades are not used. Google ratings were collected from Google search results on the date shown and will be re-checked.
Quote requests go to one company that pays Strive LeadGen per request, and only if this ranking already places it in the top 5 here. No company pays us for Cincinnati requests yet. We show an insurance record only where a public one exists; otherwise ask the company for a certificate.
