Best HVAC marketing agencies compared, and the three markets an HVAC campaign has to separate
Emergency calls, system replacement and maintenance plans are three different buyers with three different margins. An HVAC agency that runs them as one campaign spends your money on the cheapest of the three.
Published by AI Knows Us · Updated 22 October 2026
Search for an HVAC contractor and you are looking at three markets that share a trade name. The emergency call is decided in minutes on proximity and answer speed. The system replacement is a four figure considered purchase researched over days. The maintenance plan is a subscription sold mostly to people you have already served. The margins, the buyers and the winning tactics differ in all three.
Every question on this page comes back to one thing: has the agency separated them before quoting?
What a specialist in this trade publishes, read on 21 October 2026
Hook Agency is the clearest example of a home services specialist that publishes its economics, which makes it the useful comparison point whether or not you hire it. From hookagency.com and hookagency.com/pricing, read 21 October 2026: it describes itself as a home services digital marketing agency with a 30 person team, names its founder, and runs roofing and HVAC podcasts of its own. Its services include search engine optimisation, Google Ads management, Local Service Ads and Google Guaranteed, Google Maps SEO, Meta ads and website design, with a monthly reporting call built into the process.
Its published rates, each flagged on its own page as a starting price: local SEO from $2,800 a month for SEO only, paid search from $2,000 a month scaling with service scope and ad spend, Meta ads from $3,000 a month, a standard website at $1,000 a month totalling $12,000 over twelve months, and answer engine work as its own line at $4,000 a month or $2,000 when added to an SEO package.
That last line is the one to notice if you are planning a budget. A home services agency has put a monthly price on being found in AI driven results, as a separate purchase from SEO.
For the wider market, WebFX publishes ranges and a method at webfx.com/seo/pricing: retainers "$1,000 to $5,000 per month", consulting "$75 to $200 per hour", and a scoping rubric that scores home services as a local or regional competition level rather than a national one, which is a reasonable sanity check on any quote you receive. A third firm, scorpion.co, returned HTTP 403 to our request that day, so nothing is claimed about it here.
The three markets, and what each one needs
Emergency. Proximity, a complete Google Business Profile, Local Service Ads where available, and somebody answering the phone. Content barely matters. Answer speed matters enormously, and it is usually not the agency's to fix.
Replacement. This is where the money is and where agency work earns its fee. System comparison pages, financing explained plainly, rebate and tax credit information kept current, sizing guidance, and real photographs of completed installs. The buyer reads for two days before calling anybody.
Maintenance plans. Sold to your existing customer base, so the channel is email, text and the technician at the door rather than search. An agency charging a search retainer to grow plan membership is being paid for the wrong channel.
Ask any prospective agency to allocate your budget across those three in writing. The answer tells you in one page whether they know the trade.
The ranking criterion, stated and applied
Ranked on what the firm publishes before a sales call about price, scope and which markets it separates, measured on 21 October 2026: the specialist publishing per service monthly rates and flagging which are starting prices ranks first. Firms publishing ranges plus a scoping rubric rank next, because a buyer can reconstruct the quote. Firms publishing a service list and no economics rank below both. Firms whose pages we could not read are not ranked at all.
The honest limit: this ranks disclosure, not installation quality or lead quality. A firm that publishes nothing can run an excellent account, and you will have to find that out in the room.
The channel that is not in anybody's HVAC retainer
AI Knows Us is not an agency. We pitch for no retainers, write no campaigns, buy no media and build no websites, so nothing below is a bid against the firms named on this page. What we sell is one measurement that belongs in an agency scorecard and is almost never in one: when a buyer asks ChatGPT, Gemini, Perplexity, Claude or Google AI Overviews who to buy from, in a question that never names your business, does your name come out, and whose name comes out instead?
Replacement is the market where this bites. A homeowner spending four figures on a new system asks questions, and increasingly asks them of an assistant: which brand, what size, who installs in a named suburb, is a particular rebate still available. The answer names brands, often names an aggregator or a directory, and sometimes names contractors. If it never names you, your replacement pipeline is being shaped by a conversation you cannot see.
That is measurable, it is separate from your map pack position, and it is exactly what the $4,000 a month line on that published rate card is selling into. Measuring it and selling the work to fix it are two different purchases, and the party doing the work is the wrong party to grade it.
Two rules behind every rate we publish. The buyer question never names the business being measured, because a question containing the brand name produces an answer containing it. And every rate carries a 95 percent Wilson interval, so a move inside the noise is reported as noise. Our rendered pricing text carries no single sign on, no white label, no SOC 2, no ISO and no data processing agreement, and Profound publishes both single sign on and SOC 2 on its enterprise tier at tryprofound.com/pricing, read the same day, where we publish neither.
Our own numbers, for anyone checking that we publish what we ask agencies to publish. The full ladder is plain text at aiknowsus.com/llms.txt, read 21 October 2026: SEO Start $149 a month with no buyer questions watched, Growth $299 with 100 buyer questions watched, 1,200 scheduled answers a month and five engines, SEO Scale $699, Scale $599 with 300 questions, Inbound $1,099 with 200 questions, Outbound $1,299 with 30 questions and four engines, Agency $1,299 with 80 questions and 12,300 credits, Everything $1,799 with 300 questions and 3,600 scheduled answers. A 1,000 credit top up is $49 and $149 is the published United States floor. Managed GEO is listed at Rs 88,499 to Rs 2,35,999 a month with a three month minimum, published in rupees only, so we quote the rupee figure rather than converting it. A credit is one buyer question put to one app once; a Claude check costs three credits and most checks cost one.
Correction, 21 October 2026. This page used to say that our pricing page serves rupee prices in its first response and that a crawler reading it sees rupees. That was wrong. Requested as a crawler on 21 October 2026, it returned 119,203 bytes carrying 24 dollar figures in its visible text, every plan price among them, alongside 31 rupee figures, and it states in its own words that it is rendered on the server for every visitor and every crawler. The plain text file is the server rendered source.

What HVAC owners ask about marketing agencies
Specialist or local generalist? A trade specialist arrives with the page inventory and the seasonal calendar already built, which is most of the first six months of work.
What should I pay? The published specialist rate for local SEO in this trade was $2,800 a month on 21 October 2026, and the wider market range runs from $1,000 to $5,000. A single city contractor should sit at the lower half of that.
Are Local Service Ads worth it? For emergency work, yes, because you pay per lead and the badge affects click through. The screening requirements are the real barrier.
How seasonal should the budget be? Heavily. Replacement demand clusters around the first hot and first cold weeks, and a flat twelve month budget underspends exactly when the money is there.
