HVAC SEO pricing isn't arbitrary — it reflects the amount of work required to outrank your competitors in a specific market. Three factors account for most of the variation in quotes you'll receive.
1. Market Competition
Ranking for "AC repair" in a small rural county is a fundamentally different challenge than ranking for the same term in Phoenix or Atlanta. Competitive metro markets require more content, stronger backlink profiles, and faster technical execution. Agencies price accordingly.
2. Campaign Scope
A local SEO campaign focused on Google Business Profile optimization and map pack rankings costs less than a full campaign covering technical SEO, city-page content, link acquisition, and reputation management. Make sure any quote you receive specifies what's actually included — not just "monthly SEO."
3. Your Site's Starting Point
If your site has crawl errors, thin pages, or a history of spammy backlinks, the first few months of any engagement will include cleanup work before growth work begins. This is often invisible in proposals but has a real impact on how quickly you see results.
Secondary factors that influence cost include the number of service lines you're targeting (HVAC-only vs. HVAC + plumbing + electrical), whether you're operating across multiple locations, and how aggressively you want to acquire backlinks from local and industry sources.
When comparing quotes, ask each agency to break the cost down by category: technical SEO, content production, local SEO, and link building. A quote that doesn't specify these components is difficult to evaluate fairly.
