How we chose these

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

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