TL;DR
HVAC SEO retainers run from $350 a month to $5,000+ depending on the shop. The honest short list: Skill Mammoth (ours, published flat pricing from $350 with AI search built in), HVAC Webmasters (the pure HVAC specialist), Hook Agency (the big contractor-niche name, SEO from a published $2,800 a month), RYNO Strategic Solutions (the enterprise tier that absorbed Blue Corona), Built Right Digital (the value specialist), and Thrive (the full-service generalist). The match matters more than the badge count: a $2M residential shop and a $20M multi-market operation should not hire the same agency, and any salesperson who quotes you before asking your call volume is reading from a script.
Disclosure first, since we're on our own list: Skill Mammoth sells HVAC SEO, so read our entry with the same skepticism you'd read anyone's. The other five are real competitors we respect enough to name, link, and screenshot, the same way our HVAC PPC roundup and HVAC marketing agencies guide recommend shops we compete with. For each: who they fit, what they charge when it's public, and what we'd tell you privately.
1. Skill Mammoth (ours)
Published flat pricing, which is rarer in this industry than it should be: SEO support plans at $350, $750, and $1,500 a month, month-to-month, with AI search optimization included rather than sold as a $2,000 add-on. The wheelhouse is residential HVAC companies from owner-operator to about $5M who want local SEO, review engines, and a website built by the same team that ranks it. Honest limitation: we're a small team. If you want a 40-person account squad and quarterly business reviews in a conference room, two shops below do that better; you're paying for their conference room either way.
2. HVAC Webmasters
The pure specialist: HVAC contractors only, out of Texas, with their own DataPins local-SEO software and a "$99 to start" front door. Deep niche pattern-recognition from hundreds of HVAC accounts, and their sister shop Roofing Webmasters runs the same playbook for roofers. The tradeoff of any high-volume specialist is templating: your site and strategy will look like their other clients' sites and strategies, which works until you're competing against another one of their clients in your own metro.
3. Hook Agency
The biggest contractor-niche brand in the space, and one of the few that publishes pricing: Local SEO starts at $2,800 a month, AEO (their AI-search product) at $4,000 standalone or $2,000 added to an SEO package, and websites at $12,000 to $24,000. Strong content machine, real rankings of their own, contractor-only client list. If budget isn't the constraint and you want the name-brand shop, Hook is a legitimate pick; our side-by-side comparison covers where we differ, which is mostly price structure and the software we build in-house.
4. RYNO Strategic Solutions
The enterprise tier. Blue Corona merged into RYNO in October 2025, so the two biggest home-services SEO brands of the 2010s now operate as one shop with serious reporting infrastructure and HVAC depth. Best fit at $3M+ revenue, multi-truck, multi-market, where their minimums and processes make sense. Below that size their machinery is built for a company you aren't yet; our RYNO comparison covers the merged operation.
5. Built Right Digital
The value-tier home-services specialist, and a savvy operator: their agency roundups rank on this exact search, which tells you they understand SEO from the inside. Google Ads from around $999 a month, SEO priced custom but positioned under the big shops. A sensible pick when budget is the binding constraint and you still want a specialist; the fuller picture is in our Built Right comparison.
6. Thrive Internet Marketing Agency
The full-service generalist with an HVAC page and a deep bench across every channel. The trade is the same one from our Thrive comparison: HVAC is one vertical among dozens, and your results depend heavily on which team you land. Pick Thrive when you want every marketing channel under one large roof more than you want a trades specialist.
The comparison
| Company | Pricing signal | Best for |
|---|---|---|
| Skill Mammoth (ours) | $350 to $1,500/mo published, no contracts | Residential shops wanting flat fees + AI search included |
| HVAC Webmasters | "$99 to start," custom retainers | Owners who want a pure HVAC specialist |
| Hook Agency | SEO from $2,800/mo published | Bigger budgets wanting the name-brand contractor shop |
| RYNO (with Blue Corona) | Enterprise-level | $3M+ multi-market operations |
| Built Right Digital | Ads from ~$999/mo, SEO custom | Budget-first specialist work |
| Thrive | Custom | Everything under one large roof |
| Verdict | Match the agency to your size and ask every one of them the same question: which client of yours, in my revenue range, ranks today? Walk if they can't name one. | |
Want HVAC SEO with the price printed on the box?
Flat monthly plans from $350, no contracts, AI search included. We'll show you exactly what we'd do in the first 90 days before you pay anything.
How to actually choose
Three questions separate the contenders from the invoice factories. What happens in the first 90 days, specifically, and how much of it is setup theater? Who owns the website, content, and analytics when we part ways? And can I see your own rankings, since an SEO company that can't rank itself is telling you the plan for your money. Whoever you pick, make sure the channel order is right first: for most residential HVAC shops the sequence is Google Business Profile, then organic SEO, with paid search layered on top rather than substituting for the foundation.
Frequently asked questions
Who are the best HVAC SEO companies?
The strongest bench: Skill Mammoth for flat published pricing with AI search included, HVAC Webmasters as the pure HVAC specialist, Hook Agency for the name-brand contractor shop (SEO from $2,800 a month), RYNO for $3M+ enterprises after absorbing Blue Corona, Built Right Digital for budget-first specialist work, and Thrive as the full-service generalist.
How much does HVAC SEO cost?
Realistic 2026 range: $350 to $5,000+ a month. Skill Mammoth publishes plans at $350, $750, and $1,500; Hook publishes SEO from $2,800; most other shops quote custom retainers after a discovery call, commonly $1,500 to $3,500 for a single-market residential company. Under $300 a month buys reporting, not work.
How long does HVAC SEO take to work?
Meaningful movement in 90 to 120 days for map pack and service pages in a typical metro, with compounding gains through months 6 to 12. Anyone promising page one in 30 days is describing either a keyword nobody searches or a tactic that gets you burned. Seasonality matters too: work started in fall is positioned for the summer AC surge.
Should an HVAC company hire a niche agency or a generalist?
Niche shops (HVAC Webmasters, Hook, us) bring pattern recognition from hundreds of contractor accounts and win on speed to competence. Generalists like Thrive win when you want every channel managed under one roof. The failure mode of niche is templated sameness; the failure mode of generalist is being vertical number 37. Ask who specifically touches your account weekly.
What happened to Blue Corona for HVAC SEO?
Blue Corona merged into RYNO Strategic Solutions in October 2025, and the combined operation runs under the RYNO brand. Existing Blue Corona HVAC clients were folded in, and the merged shop remains the enterprise pick for $3M+ operations that want big-shop process and reporting.
