TL;DR
Ten companies sell HVAC SEO seriously, and as of October 15, 2026, seven of them publish a price. Skill Mammoth (ours) runs $750 and $1,500 a month, month to month, no setup fee. Built-Right Digital publishes flat tiers at $1,499, $2,499 and $4,999 sorted by your revenue. Hook Agency starts SEO at $2,800. Plumbing & HVAC SEO prints $2,495 a month plus a $5,000 setup on a 12-month term. 1Digital runs $899 to $4,499 on a six-month term, or a $499 to $999 local campaign on its own platform. CI Web Group starts its SEO agent at $1,000. Thrive says $500. HVAC Webmasters says "$99 to start" and names the rest on the phone, RYNO and LeadHub quote on the call, and Blue Corona, now inside RYNO, says $5,000 and up. A one-to-three-truck residential shop should expect $750 to $1,500 a month for a program with written pages, Google Business Profile work and review handling. A multi-truck company with a commercial division is a $2,500 to $5,000 problem. The table below has every number with its source.
Disclosure first: Skill Mammoth sells HVAC SEO and we are ranked first below, so read our entry with the same skepticism you bring to anyone's. Every other agency on this list is a real competitor, named, linked and screenshotted, with its price quoted from its own page. Two of them, Hook and Built-Right, publish lists like this one with themselves at number one, and both lists rank on the search you probably used to find this page. We do the same thing. The difference we can offer is that every row in the table carries a published number or the words "not published," and the "best for" column is the honest answer, which in four rows is not us.
If you want the strategy before the shortlist, the HVAC SEO guide covers the seasonal keyword map, the service and city pages, and the 90-day plan every agency here sells a version of. The wider agency picture, ads included, is in best HVAC marketing agencies. This page is for the owner who has decided to hire out the search work and wants to know what the money buys before the discovery call.
How we ranked them
Four things, in order. Whether the price is published, because an agency that prints its number is telling you how it sells. Whether the shop knows HVAC, meaning the seasonal swing between furnace searches in October and AC searches in June, the maintenance-agreement economics, and the difference between a replacement lead and a repair call. The contract, because a 12-month term on a plan under $2,000 should make you ask what happens at month four if nothing has moved. And the revenue band each agency is built for, which two of the ten state outright and the rest reveal in their prices. We did not rank on size of client list or number of awards, because neither predicts whether your map pack moves.
The ten HVAC SEO companies, compared
| Company | Published price (Oct 15, 2026) | Contract | Best for |
|---|---|---|---|
| Skill Mammoth (ours) | $750 or $1,500 a month with SEO; no contract | Month to month | Residential shops to about $5M that want a flat fee with AI search included |
| Built-Right Digital | $1,499 (new), $2,499 (to $1M revenue), $4,999 (to $5M), custom above | Not stated on the pricing page | Owners who want a flat tier matched to revenue and paid ads from the same team |
| Hook Agency | SEO from $2,800 a month; AEO $4,000 or $2,000 added; sites $12,000 to $24,000 | Not stated | Bigger budgets buying the name-brand contractor agency |
| Plumbing & HVAC SEO | $2,495 a month plus $5,000 setup; LSA management from $549; Google Ads $1,500 | 12 months | Established multi-truck shops in one metro |
| 1Digital Agency | Local SEO $899 to $4,499 a month; WorkspaceCMS local campaigns $499 to $999 plus site from $89 | Six-month initial term, then monthly | Owners who want a platform and a menu instead of a retainer |
| CI Web Group | SEO, AEO and GEO agent from $1,000 a month; websites $500 to $50,000; entry blogging tier $600 | No contracts, 30 days' notice | HVAC companies on manufacturer co-op programs, and owners who want AI tooling over a team |
| Thrive Internet Marketing | SEO "starting at $500 a month"; local SEO $500 to $1,500 | Month to month | Every channel under one large roof |
| HVAC Webmasters | "$99 to start," one-time setup fee, fixed monthly rate not published | No long-term contracts (per the sister site) | Owners who want an HVAC-only production shop |
| RYNO Strategic Solutions (with Blue Corona) | Not published; Blue Corona's page says "$5,000 per month and above" | No long-term contracts | $3M-plus, multi-market operations with a marketing hire |
| LeadHub | Not published | Not stated | Shops that want cost-per-lead management and SEO from one San Antonio team |
| Verdict | One to three trucks: us, Thrive's local tier or 1Digital's platform, and the program is the profile, the service pages, the reviews and a handful of city pages. Four to ten trucks: Built-Right's $2,499 tier, Plumbing & HVAC SEO or Hook, and ask what the setup fee buys. Multi-market: RYNO. Ask the three silent ones for the number in writing before the demo. | ||
1. Skill Mammoth (ours)
Ours, so weigh it. The SEO + AI Search program comes in three published tiers, all month to month with no setup fee. Local at $750 a month covers weekly Google Business Profile management, citations on Yelp, Angi, BBB and 20-plus local directories, LocalBusiness and Service schema, two answer-first posts a month, an automated post-job review request system with responses to every review, and a baseline ChatGPT, Perplexity and AI Overviews visibility setup. Authority at $1,500 adds up to five new city and neighborhood pages a month, curated authority placements, four to six posts, a competitor gap analysis and a monthly strategy call. Pro at $3,000 adds full topic clusters, original research and digital PR. Every line item is on the pricing page so you can hold any other quote against it, and the SEO packages guide explains what each band should contain.
The fit is a residential HVAC company from owner-operator to about $5 million that wants local SEO, a review engine and a website built by the same team that ranks it. The site is $3,000 (or $150 a month on Easy Start), owned outright and included with every plan, which runs from $350 a month. The honest limitation is size: we are a small team with a residential focus, and a $20 million multi-market operation with an in-house marketing director belongs with RYNO or Built-Right's Pro tier.
2. Built-Right Digital
A Chicago home-services agency that publishes the clearest tier ladder on this list and sorts it by your revenue, which is a smart piece of self-qualification. Essentials at $1,499 a month is "for new businesses" and covers listing management, core on-page and technical SEO, tracking and web management. Launch at $2,499 is "for up to $1M revenue businesses" and adds off-page SEO and a marketing support team. Scale at $4,999 is for companies up to $5 million and is the first tier with paid ads management and a monthly strategy review. Pro is custom for $5 million and up. The comparison grid underneath prints the blog output per tier, 500, 800, 3,200 and 6,400 words a month, which is the kind of specificity most agencies avoid. Stand-alone plans are printed too: SEO at $999 a month or $3,499 for SEO Plus, an SEO plus AEO package at $2,999, Google Ads management at $999, Meta at $1,999 and Local Services Ads at $299, with websites at $5,750, $9,590 or $14,390 one time or $599 to $1,499 a month over twelve payments.
Built-Right also runs the most aggressive content program in the category, with roughly 150 "best agency" lists and a page for nearly every trade-by-service combination, and their HVAC SEO list ranks first for the search that likely brought you here. That tells you they can rank a page. What the pricing page does not say is the contract term, and the $1,499 tier has no off-page work, so ask what moves a map pack at that price. Our Built-Right comparison has the fuller picture.
3. Hook Agency
The loudest brand in contractor marketing, Minneapolis-based, trades-only, and one of the few that prints a rate card. Local SEO starts at $2,800 a month. AEO, their AI-search product, is $4,000 standalone or $2,000 added to an SEO package. PPC starts at $2,000, Meta ads at $3,000, and websites run $12,000 for a standard build or $24,000 for custom, split over 12 months, with complex builds "up to 50k." The content team is large and their own HVAC roundups rank, which is the same signal Built-Right sends.
The fit is a contractor with the budget who wants the shop its competitors already know by name. The setup fee and contract term are not on the page, so ask. The structural differences between Hook and us are in our Hook comparison, and they mostly come down to price architecture and who builds your software.
4. Plumbing & HVAC SEO
The trades-only shop that publishes its whole rate card, fifteen years in one industry. The core program is $2,495 a month for one trade in one location, defined as your primary city plus ten surrounding towns, with a $5,000 one-time setup that covers competitive research, tooling, hosting and the website build. Add-ons are printed too: Local Services Ads management from $549 a month and Google Ads management at $1,500. The term is 12 months, which is the longest on this list and the thing to weigh against the transparency. For an established multi-truck shop in one metro that wants a specialist with a published menu, this is a strong fit. For a two-truck company, the setup fee alone is six months of a cheaper program.
5. 1Digital Agency
A different model, and the most detailed menu here. Standard local SEO retainers run Launch $899, Essential $1,599, Pro $2,499, Plus $3,299 and Premium $4,499 a month, with national versions from $1,499 to $5,999, on a six-month initial term that goes month to month afterward, with no setup fee. One-time on-site SEO comes in hour buckets at $1,699 for five hours, $3,199 for ten and $4,399 for fifteen. For local businesses on its own WorkspaceCMS platform, local campaigns run $499, $699 or $999 a month on top of a site plan from $89, also on a six-month commitment. The page states that out-of-scope work bills at $185 an hour.
The fit is an owner who wants to pick from a menu and pay a platform fee rather than negotiate a retainer, with HVAC as one of the trade verticals it has served for years. The trade-off is that the platform campaigns tie the site to the vendor, so ask what you take with you.
Want a number before the call?
Fifteen minutes on your trucks, your service area and your current rankings, and we will tell you which three of the ten above fit and what each should cost you, including when it is not us.
6. CI Web Group
An AI-first "marketing operating system" for the trades that has been building HVAC websites for a long time and now sells its work as agents on its own Hydra OS platform. The published numbers are scattered across the homepage rather than in a grid: websites "from as low as $500 up to $50,000," a $600-a-month entry tier for daily blogging, an SEO, AEO and GEO agent from $1,000 a month, and marketing that runs "up to about $3,000 per market and service category." No contracts, 30 days' notice, and no paid advertising, which is unusual for an HVAC agency. The distinctive fit is manufacturer co-op: CI Web Group builds large sites that follow co-op advertising rules while keeping local search presence, which matters if a Carrier or Lennox program is paying part of your marketing bill. The trade-off is that the service is tooling-heavy and the deliverables are described in platform terms, so ask who touches your account weekly.
7. Thrive Internet Marketing Agency
The full-service generalist, Arlington, Texas, since 2005, month to month with no long-term contracts. The pricing page says SEO costs "$500 to $10,000+ per month," small businesses start "at $500 a month," and local SEO runs $500 to $1,500 with Basic, Advanced and Premium plans that carry no printed price. HVAC is one of roughly a hundred verticals, and the person on your account may have learned the trade last quarter. The fit is an owner who wants every channel managed by one large vendor more than a trades specialist watching the map pack every morning. Our Thrive comparison covers the pattern.
8. HVAC Webmasters
The pure specialist out of Fort Worth, HVAC contractors only, with its own DataPins software posting geo-tagged job check-ins to your site, and a "$99 to Start! Call for Details" banner at the top of the page. The sister site, Plumbing Webmasters, fills in the structure the HVAC page leaves out: a one-time setup fee, a fixed monthly rate that "does not vary by market," no long-term contracts, and monthly billing that starts when the site goes live, typically two to three weeks after signup. Neither site prints the setup fee or the monthly figure. The depth is real after hundreds of HVAC accounts, and so is the production-line model: your site and strategy will look like other clients' sites, occasionally in your own metro. Ask about exclusivity by market and what the $99 covers.
9. RYNO Strategic Solutions, with Blue Corona
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 Phoenix-based shop with serious reporting infrastructure and a deep HVAC case history. RYNO does not publish a price; Blue Corona's surviving pages say services "can run anywhere from $5,000 per month and above," with no long-term contracts and full ownership of everything built. The fit is $3 million and up, multi-truck, multi-market, with someone in-house to read the reports. Below that size the machinery is built for a company you are not yet, and the RYNO comparison covers what the merged shop looks like from the client side.
10. LeadHub
A San Antonio home-services agency serving air conditioning, plumbing, electrical, roofing, pest control, windows, water softening and foundation repair, with SEO sitting next to a cost-per-lead management service, PPC, web development and CRM integration. The homepage leads with client results (+162 percent and +393 percent) and a free discovery call, and publishes no price, minimum or plan. The fit is a shop that wants one team managing SEO and paid leads against a cost-per-lead target. Ask for the number in writing before the demo, and ask which HVAC client in your revenue band ranks today.
Two more names come up in HVAC circles and are not ranked above because neither sells SEO as the core product. Lemon Seed Marketing works exclusively for the trades on branding, creative and marketing coaching, with no published price, and is the right call if the problem is the brand on the truck rather than the map pack. Scorpion is the large platform vendor with no published pricing, best suited to multi-location companies that want software and services bundled.
What HVAC SEO should cost by shop size
The published numbers above sort into three bands, and the band should match your competition, not your ambition. One to three trucks in one metro: $750 to $1,500 a month, and the program is a correct and complete Google Business Profile, a page per service including repair, replacement and maintenance agreements, pages for the suburbs you drive to, a review system that outpaces the two competitors above you, and schema. That band is us, Thrive's local tier, 1Digital's platform campaigns or Built-Right's Essentials, and at the top of it, Built-Right's Launch. Four to ten trucks with a commercial division: $2,500 to $5,000, which adds commercial pages, more cities, authority links and a monthly call, and that is Hook, Plumbing & HVAC SEO, Built-Right's Scale tier or our Pro tier. Multi-market with five figures a month to spend: RYNO, and the question becomes reporting and attribution rather than page count. Ahrefs' survey of 439 SEO providers puts the most common retainer at $501 to $1,000 a month, so most HVAC companies buy the first band, and how much SEO costs has the full market ranges to check any quote against.
Five questions that expose a weak proposal
Which suburb's map pack moves first, and by when. What the fee is, in writing, before the demo, including the setup fee that four of the ten above either charge or do not print. Who owns the website, the content and the analytics when you leave, because two platforms on this list tie the site to the vendor. What happens in the first 90 days specifically, and how much of it is setup theater. And what the agency does about AI search, because "AC repair near me" is increasingly answered by a paragraph naming three companies, and an agency with no answer is already behind. The HVAC PPC roundup covers the paid side of the same decision, and the HVAC website design guide shows what the site under the SEO should look like.
Frequently asked questions
How much does HVAC SEO cost?
Published prices on October 15, 2026 run from $500 a month at Thrive and $750 at Skill Mammoth, through $899 to $4,499 at 1Digital, $1,000 and up at CI Web Group, $1,499 to $4,999 at Built-Right Digital, $2,495 plus a $5,000 setup at Plumbing & HVAC SEO and $2,800 at Hook, to $5,000 and up at Blue Corona inside RYNO. HVAC Webmasters and LeadHub price on the call. A one-to-three-truck residential shop should expect $750 to $1,500 a month for a program with written pages and review handling.
Who are the best HVAC SEO companies?
For a residential shop that wants a flat published fee: Skill Mammoth, Built-Right Digital or 1Digital. For an established multi-truck company: Hook Agency, Plumbing & HVAC SEO or Built-Right's Scale tier. For an HVAC-only production shop: HVAC Webmasters. For manufacturer co-op programs: CI Web Group. For multi-market enterprises: RYNO with Blue Corona. For every channel under one roof: Thrive.
Should an HVAC company hire a niche agency or a generalist?
Niche shops bring pattern recognition from hundreds of contractor accounts and win on speed to competence; the failure mode is templated sameness, sometimes in your own metro. Generalists win when you want every channel managed by one vendor; the failure mode is being vertical number 37. Either way, ask who specifically touches your account weekly and which HVAC client in your revenue band ranks today.
How long does HVAC SEO take to work?
Map pack and service-page movement in 90 to 120 days in a typical metro, compounding through months six to twelve. Timing is seasonal: work started in late summer is positioned for furnace season, and work started in winter is positioned for the June AC surge. Anyone promising page one in 30 days is describing a keyword nobody searches.
Do HVAC SEO companies require contracts?
Plumbing & HVAC SEO requires 12 months and 1Digital six months. Skill Mammoth, Thrive, CI Web Group and RYNO state no long-term contracts, and HVAC Webmasters' sister site says the same. Built-Right, Hook and LeadHub do not state a term on their pricing pages, so ask before signing, and ask who owns the site and the Google Business Profile if you leave.
Is Skill Mammoth an HVAC SEO company?
Yes, among the home service trades we serve. The program is Growth at $750 or Authority at $1,500 a month, month to month with no contract, on a Smart Website we build ($3,000 or $150 a month on Easy Start), and includes the AI search work. The HVAC SEO guide on this site is the strategy we run, and the HVAC page shows the work.
