How to evaluate contractor reviews
- Read recent positive and critical reviews, not only the average rating.
- Look for comments about communication, scheduling, workmanship and follow-through.
- Check whether the contractor responds publicly and addresses problems specifically.
- Compare reviews for the exact service you need, such as HVAC, solar, roofing or battery work.
- Verify licenses, warranties and written scope separately; reviews are one part of due diligence.
| Review signal | What it can tell you | What it cannot prove by itself |
|---|---|---|
| Recent project detail | Current customer experience | Future project outcome |
| Company response | Communication style | Whether every dispute is resolved |
| Service-specific feedback | Relevant trade experience | Your exact scope or price |
Use reviews as one part of contractor due diligence
- Verify the contractor license separately from review sites.
- Read the written proposal before relying on a reviewer’s project price.
- Look for reviews involving the same trade and similar project size.
- Check how recent complaints were answered and whether responses are specific.
- Ask for warranty and permit responsibility in writing before signing.

How we handle feedback — including the critical kind
No contractor gets every job perfect. When something isn’t right, we respond on the platform, on the record, and fix what’s fixable. If you’re comparing contractors, we’d actually encourage you to read our critical reviews and our responses to them — how a company behaves when something goes sideways tells you more than its five-star quotes do.
What we don’t do: write our own reviews, pay for reviews, or ask customers to change a rating. Every review you’ll find is from a homeowner who chose to leave it.
Compare reviews by project type
The most useful review describes a project like yours. For HVAC, look for sizing, comfort and startup testing. For solar and battery, look for design communication, utility steps and backup-load planning. For roofing, look for waterproofing, cleanup and how changes were documented.
