Eight agencies ranking for this question publish their prices. The range runs from $399 to $5,000 a month for work described in almost identical language. Here is what actually separates the ends of that range, and how to tell where your company sits.
We quote after the audit, because quoting before it would be a guess. The audit is free and yours either way.
HVAC SEO typically costs between $2,000 and $10,000 a month with an agency, with most residential contractors paying $3,000 to $7,000. Doing it yourself runs roughly $600 to $1,400 a month in tools and outsourced content, plus five to ten hours of your own time each week.
Those figures come from the agencies currently ranking for this question, who publish them on their own pages. The range is real, and so is the problem with it: the same monthly deliverables get described at $399 and at $4,500.
Three things move a quote inside that range. How many cities you serve, how competitive your metro is, and whether the agency is building anything or just reporting on it.
Before we give you our number, here is what the agencies ranking for this exact question publish about theirs.
Because "SEO" describes four different businesses.
You are buying software and reporting. Automated citation submissions, a rank tracking dashboard, maybe a monthly PDF. Nobody is writing anything or calling anyone. This tier can be worth it if you already have a strong profile and just want monitoring. It will not move map pack position, and the contractors who feel burned by SEO almost always bought here.
Profile management and a small content quota. Usually offshore writing to a template, usually four blog posts nobody reads. Better than nothing. It rarely reaches the towns at the edge of your service area, because that needs pages and links, and neither fits in this budget.
The work becomes real. Service-area pages built properly, technical fixes, link acquisition, review systems, and someone who knows your market. This is where most residential HVAC contractors should be, and it is where the market clusters for a reason.
You are usually paying for a team structure: an account manager, a strategist, a separate content department. Worth it for multi-location companies and franchises. For a single-location contractor it is mostly overhead.
The uncomfortable part: the deliverables lists at $399 and $4,500 read almost the same. Both say technical SEO, content, local SEO, reporting. The words do not distinguish them. What distinguishes them is how many hours a human spends on your account, and nobody puts that in the brochure.
Four questions decide where in the range you sit. Answer them here and the band moves.
One town needs a handful of pages. Four counties needs dozens, plus the link work to make them rank. Service area is the single biggest cost driver and it is why per-location pricing exists.
Phoenix and Dallas are not Sioux Falls. If four established contractors in your city are already running real campaigns, you are buying your way past them, and that costs more and takes longer.
A contractor with a fast, crawlable site and a clean profile starts from a different place than one carrying forty templated city pages and a suspended listing. The first three months of a campaign on a neglected site are largely repair.
This is the one contractors skip. If your average replacement is $9,400 and you close one in three quoted, a campaign producing four extra replacement quotes a month pays for itself several times over at any point in the range above. If you only do repairs at $340 a ticket, the maths is tighter and you should be at the lower end.
One town, a quiet market and a site in decent shape. Profile management and a small content quota will move you, and the free versions on our local SEO and profile pages will get you part of the way for nothing.
Get a Quote for My Actual Market →Illustrative. The real number comes out of the audit.
Ask any agency quoting you which of these four they used to reach their number. If the answer is none of them, the number came off a price list.
Our retainers run $2,500 to $7,500 a month. A contractor covering one metro sits at the bottom. A company with four locations across a major metro sits at the top.
We quote after the audit. Quoting before it would be a guess, and a quote produced without looking at your market is the thing this page has spent four sections warning you about.
Two things worth saying plainly.
We are small, and that shows up in the price. There is no account manager layer and no separate content department, which is part of why our range sits where it does. If you want the structure of a fifty-person agency, we are not that and you should expect to pay for it elsewhere.
We only work with HVAC contractors. That means the research does not start from a blank page and onboarding does not run on your retainer, which is worth more than it sounds when you are paying monthly.
Month to month after the first 90 days. The initial period exists because the first three months are mostly repair work, and nothing moves if it is stopped halfway.
The useful comparison is not agency against agency. It is organic against paid.
HVAC clicks in most markets we work in run $2,500 to $7,500, and the cost per click on HVAC service keywords is among the highest of any local trade. Work out what a booked job from Google Ads costs you today, including the clicks that never called.
Organic takes longer to start. It does not stop when you stop paying, and it does not charge you again for the same customer next season. Most published guidance puts the crossover somewhere between six and twelve months, and one of the agencies ranking for this question states it that way explicitly.
If you are currently spending $4,000 a month on paid search and nothing on organic, the question is not whether you can afford SEO. It is whether you can afford to keep renting every lead.
Sometimes no, and it is worth saying which cases.
If you serve one city, have a decent profile, and someone in your office will spend two hours a week on it, you can get a long way alone. Our local SEO and Google Business Profile pages both include the free version of the work, and we publish those knowing some readers will use them and never call.
More leads are not your constraint.
The timeline does not work.
Otherwise, the honest answer is that it depends on the four questions above, and any agency giving you a yes before asking them is selling.
For a local service business, $2,000 to $10,000 a month is the normal agency range, with most sitting between $3,000 and $7,000. HVAC sits at the higher end of local trades because the cost per click is high and the service areas are wide.
It depends on how many cities you serve, how competitive your metro is, what shape the site is in, and what a job is worth to you. The four questions above cover all of them. Our range is $2,500 to $7,500 and we quote after the audit.
For a residential HVAC contractor working a defined territory with capacity to fill, usually yes, because emergency demand goes to search first and the visibility compounds. It is a poor fit for commercial contractors winning work through bids, and for anyone already at capacity.
Below roughly $1,200 a month you are usually buying automated citation submissions and a reporting dashboard. Nobody is writing pages or acquiring links. It can be worth it as monitoring. It will not move map pack position.
Published guidance puts the crossover against paid search somewhere between six and twelve months. Map pack movement usually shows earlier. Anyone promising payback in 30 days is describing something else.
No. One retainer covers the whole territory, and additional locations move you up the range rather than adding a per-location fee.
Ninety days, then month to month. You keep every page, every listing and every link if you leave.
The audit shows your map pack visibility across your service area, what your competitors are capturing, and what is holding your site back. Then we quote. A day for us to build, 20 minutes to walk you through, and you keep it whether or not we work together.
No contract. No pitch deck.
