How the top home service pros compare
The same ServiceAgent Score components that drive the ranking, scored side by side — so you can see at a glance where each provider is strongest.
The criteria we scored against
- 1. Trust (data & verification). Owner-verification, completeness of contact info, and review-volume credibility.
- 2. Recommendation (rating). The Google star rating, Bayesian-shrunk toward the category mean so a few 5-star reviews can't dominate.
- 3. Review depth. How many public reviews back the rating — more reviews, more reliable the signal.
- 4. Score confidence. How much data stands behind the composite score for this provider.
| Provider | Trust (data & verification) | Recommendation (rating) | Review depth | Score confidence |
|---|---|---|---|---|
| Cardinal Heating, Cooling, Plumbing & Electric | Strong | Strong | Strong | Strong |
| RQ Roofing LLC | Moderate | Strong | Moderate | Strong |
| Mr. Electric of Madison | Moderate | Strong | Moderate | Strong |
| Action Plumbing, Heating, Air Conditioning and Electric, Inc. | Strong | Strong | Strong | Strong |
| Four of Six Landscape | Moderate | Strong | Limited | Limited |
| Jacksons Yard Care LLC | Moderate | Strong | Moderate | Strong |
How we chose these
We rank every active provider in every active home-service business in Sun Prairie by a composite ServiceAgent Score (0-10) made up of two components:
Trust Score (40%) - rewards owner-verified status, completeness of contact info, presence of hours/coordinates/photos, and review-volume credibility.
Recommendation Score (60%) - Google rating Bayesian-shrunk toward the category mean using a 25-review prior so high-volume providers can't be dethroned by 5-star outliers.
Composite ServiceAgent Score = 0.6 × Recommendation + 0.4 × Trust. We re-compute as new reviews land and as providers claim their listings. The "Last updated" date at the top of this page reflects the most recent data refresh.
What we deliberately don't do: pay-to-rank, sponsored slots that masquerade as editorial picks, or hide our formula. Sponsored slots (if/when introduced) will be clearly labeled and won't affect editorial ranking.

How to choose a home service pro
The ranking does the research; these five checks help you turn the shortlist into the right hire.
- 1
Start with the top of the ranking, not an ad
The providers ranked highest in Sun Prairie earned it on review depth, rating, and data completeness — not on ad spend. Shortlist two or three from the top before you start calling.
- 2
Get two or three quotes in writing
Pricing for home service work varies by scope and local market. Written quotes from a few shortlisted pros let you compare apples to apples and spot an outlier before you commit.
- 3
Read the most recent reviews, not just the average
A strong average can hide a recent slide in quality. Sort reviews by newest and look for how the business handles problems — a thoughtful reply to a bad review often tells you more than the star count.
- 4
Confirm licensing, insurance, and scope before work starts
Ask for the license number and proof of insurance, and get the full scope of work plus any parts/labor warranty in writing before any home service job begins. Verify the license on your state board if the work is significant.
- 5
Match the provider to your actual job
A high-volume operator is great for a routine job; a smaller specialist may be a better fit for an unusual one. Use the scorecard above to pick for your situation, not just the overall rank.
