Local SEO operates on a different set of signals than standard organic search. For HVAC companies competing in the Map Pack — the three-business block that appears above organic results for searches like "AC repair near me" or "furnace installation [city]" — Google evaluates three broad categories: relevance, proximity, and prominence.
Reviews fall under prominence. Google's own documentation identifies review signals as a factor in local ranking, and in our experience working with local service businesses, review profile health consistently separates Map Pack incumbents from companies stuck in positions four through ten.
What Google appears to weight most heavily:
- Review velocity — are new reviews arriving regularly, or did activity stop eighteen months ago?
- Star rating average — not just the raw number, but whether it has held stable or trended in one direction
- Response rate — owner responses signal an active, managed business listing
- Review content — reviews that mention specific services ("AC tune-up," "heat pump replacement") reinforce your relevance for those queries
Industry benchmarks suggest that HVAC companies with fewer than ten recent reviews — meaning within the last ninety days — are at a structural disadvantage against competitors who have implemented a systematic review process. The gap compounds over time: a competitor generating eight reviews a month will have a dramatically stronger profile than a company relying on customers to volunteer reviews unprompted.
One important nuance: review signals influence Map Pack rankings, but they also influence click-through rates from the Map Pack itself. A 4.8-star rating with 200 reviews will draw more clicks than a 4.2-star rating with 30, even if both businesses appear in the same three-pack. Rankings and conversions are both at stake.
