How we chose these

Same scoring engine as the main Scottsdale hvac ranking, with an additional filter step: we look for Maintenance signals in each provider's business categories, service tags, and recent review text.

When the Maintenance filter would surface fewer than five providers, we fall back to showing top-rated hvac pros generally - they are far more likely to handle maintenance work than an unrated provider would be.
