How were these hvac companies chosen?
We rank every HVAC company we track in the Boise area using public customer review data — the average star rating weighted by how many customers have reviewed the company. A high rating across hundreds of reviews outranks a perfect score from a handful. No company can pay for a higher position.
Can a company pay to be on this list?
No. Editorial rankings are computed from review data and are never for sale. When a company partners with us to receive customer referrals, we label it clearly as a partner — and that partnership never changes its position in the ranked list.
