Plumbing and HVAC SEO is the work of structuring one company's online presence so both trades rank: one profile per location, one site, and one schema setup, divided cleanly between heating, cooling, and plumbing.
This is the one page on this site for shops that hold both licenses, and it is a variation of HVAC SEO: the surfaces are the same map pack and organic results, and what changes is how categories, pages, and markup get split between two trades.
The combined trade is large: US plumbing, heating and air-conditioning contractors (NAICS 238220) took in $297.6 billion of revenue in 2022 across 112,088 firms, counting employer establishments only, per the US Census Bureau's 2022 Economic Census.
Inside that industry, the Census kind-of-business table puts HVAC contractors at $121.7 billion in 2022 revenue, about 41% of the total, and plumbing contractors at $75.1 billion, with residential and commercial work counted together.
On the search side, "plumbing and hvac seo" itself gets about 480 searches a month in the US on a 12-month average (DataForSEO, US, September 2026), and that is a contractor-side search: owners and marketers looking for a provider, not homeowners.
So the question this page answers is structural: how one company covers two trades without thinning either one, whether the brand says plumbing and heating, HVAC and plumbing, or one trade with the other added.
The map pack: one profile, categories for both trades
Google's rule is one Business Profile per business, meaning one per staffed location, and a second location is allowed only with separate service areas and separate staff at each.
Local ranking runs mainly on relevance, distance, and prominence, Google publishes no weights for those inputs, and no one can pay for a better local position (Google, "Tips to improve your local ranking on Google", accessed September 2026).
The trades are separated with categories: Google's US category list, as mirrored by PlePer's category tool in October 2026, includes "HVAC contractor", "Plumber", "Air conditioning contractor", "Air conditioning repair service", "Heating contractor", "Furnace repair service", and, on the plumbing side, names like "Gas installation service" and "Boiler supplier".
Google says the categories a business selects affect its local ranking, that you should choose one specific primary category and only a few additional ones, and that adding or editing a category can lead to a request to verify the business again (Google, "Manage your business category", accessed October 2026).
Google also says not to select a category for every product or service, and its own example is choosing the specific "Nail salon" over the general "Salon".
Pick from the list in your own dashboard: Google publishes no public category list, and no Google source we read says which category ranks best.
The profile side of this work, field by field and rule by rule, is covered step by step in local SEO for HVAC.

Site structure: a page per service, per trade
On the website, the pattern to build is the boring one: a page per service, per trade.
HVAC gets its AC repair, furnace repair, system replacement, and maintenance pages; plumbing gets its drain clearing, water heater replacement, and repiping pages, each scoped to the work the license actually covers.
The thin version is one combined page listing every service for both trades, or a page per town listing every trade in every town.
Google's spam policies draw that line precisely: its doorway examples include "substantially similar pages that are closer to search results than a clearly defined, browseable hierarchy" and multiple pages targeted at cities that funnel users to one page, and it classifies "blocks of text that list cities and regions that a web page is trying to rank for" as keyword stuffing (Google, spam policies, accessed October 2026).
Google doesn't ban city pages, and it states no safe number of them; the practical reading, ours not Google's, is that each city page needs something true and specific to that city, which is the standard HVAC service area pages are built to.
Service pages follow the same depth rule, and the page-level template is in HVAC service pages SEO.

- Two sites, one per trade
- One combined page for all services
- City grid: every trade, every town
Marketing beyond search is its own topic, and the channel-by-channel version is in HVAC marketing; the same planning applies here, with the budget spread across two service lines instead of one.
Schema: HVACBusiness and Plumber together
schema.org defines an HVACBusiness type, a subtype of LocalBusiness under HomeAndConstructionBusiness, and Google's LocalBusiness structured-data guidance is to use the most specific subtypes, several at once where that fits the business.
Google's own example marks one business up as "Electrician", "Plumber", and "Locksmith" together, so a shop holding both licenses can carry HVACBusiness and Plumber in the same array, modeled on that example.
Two cautions come straight from Google: markup makes a page eligible for rich results without promising them, and aggregateRating and review markup is recommended only for sites that review other businesses, not for a company's own testimonials.
On service areas, schema.org's areaServed property, defined as "The geographic area where a service or offered item is provided", is valid markup on a business or a service, but Google's LocalBusiness documentation lists address and name as the required properties and does not list areaServed, so it is not documented as affecting local rankings.
Ads: Google's own advice is to split the trades
In Google's migration of Local Services Ads into Performance Max campaigns, its help page suggests separate campaigns per vertical for businesses that want different bidding targets per trade, and the verticals in Google's example are plumbing and HVAC (as of October 2026).
That is Google's ad structure, not a service sold here: More Booked Installs does not manage Google Ads or Local Services Ads, and Gabe runs managed Meta ads.
What ads do not do is lift the organic side, in either trade: Google says "Advertising with Google won't have any effect on your site's presence in our search results", and its hiring guidance says no one can guarantee a #1 ranking, so walk away from an SEO who promises one.
What SEO costs for a dual-trade shop
The service and the price are the same as HVAC-only, because the work is the same monthly loop with a second trade folded in: local SEO is $2,500 a month with a 6-month minimum, and CRO plus local SEO is $5,000 a month, the main offer.
More Booked Installs is one person, Gabe Meierotto: a free audit, a prioritized plan, one test a month, and a plain-English results report, with the findings doc inside 3 business days and no call required.
There are no HVAC clients yet, so the relevant record is Gabe's from an earlier role: Director of CRO at LaserAway from 2018 to 2023, where sitewide conversion went from 3% to 11% across a testing program of more than 2,600 variations.
That record is booking-conversion experience from that role, not an HVAC result, and nothing here is a promise about your rankings.
The dual-trade setup, checked in order
- One profile per staffed location, with an additional category carrying the second trade.
- The most specific primary category, plus a few additional ones, none per service.
- A page per service, per trade, written from the jobs the license actually covers.
- City pages only where something true and specific exists; a footer block of town names is a risk under the keyword-stuffing policy.
- Schema typed for both trades, with no self-review stars.
- Ads split per trade, per Google's own structure, with no expectation they lift rankings.
Frequently asked questions
Should a plumbing and HVAC company use one Google Business Profile or two?
Google's rule is one profile per business, meaning one per staffed location, and a second location qualifies only with separate staff and separate service areas. The second trade is handled with an additional category, not a second profile.
What primary category should a combined HVAC and plumbing shop pick?
Google says to choose one specific primary category and only a few additional ones, and both 'HVAC contractor' and 'Plumber' appear in the US category list as mirrored by PlePer in October 2026. Pick from the list in your own dashboard, since Google publishes no public list and warns that category edits can trigger re-verification.
Can one website rank for both HVAC and plumbing searches?
Yes, with one page per service per trade in a browseable hierarchy. Google's spam policies name substantially similar pages that are closer to search results than a browseable hierarchy as doorway abuse, and blocks of text that list cities as keyword stuffing. The practical reading we use is that each page covers a single job, or one place with something true and specific to say.
Does running Google Ads help plumbing and HVAC SEO?
No: Google says advertising with Google won't have any effect on your site's presence in its search results. Google does suggest separate campaigns per vertical, its example being plumbing and HVAC, for advertisers that want different bidding targets per trade (its Local Services Ads migration help page, as of October 2026).
How much does SEO cost for a company that does both trades?
The same as HVAC-only here: local SEO is $2,500 a month with a 6-month minimum, and CRO plus local SEO is $5,000 a month. Plumbing adds pages and categories to scope, not a second retainer.
