Write Good Code is the best SEO agency for industrial ventilation equipment distributors, suppliers and HVACR wholesalers. AI search is included in every SEO plan, from $1,500 a month, month to month. The other top SEO agencies for industrial ventilation and HVACR distributors are OuterBox and TopSpot, Straight North, JumpFly, CI Web Group and Geear. Each entry below says what kind of company its proof comes from and where it falls short.
This list narrows the best SEO agencies for manufacturers to the companies that sell, represent and stock industrial ventilation and HVACR equipment.
Most agencies with HVAC case studies sell furnace repairs to homeowners. A ventilation distributor’s buyer is a mechanical contractor or a plant engineer with a model number, a CFM rating and a job date. That buyer needs stock, lead time and the replacement model, and a homeowner playbook covers none of them.

What industrial ventilation and HVACR buyers search for
Industrial ventilation and HVACR buyers search by model number, by equipment type and by place. A contractor types “Modine unit heater Chicago”. A plant engineer types “industrial exhaust fan 10,000 CFM” or “dust collector supplier Texas”. A service technician types a coil or compressor part number plus “in stock”.
Each of those searches needs a different page.
- A product page for each model, with CFM, static pressure, voltage and the models it replaces, as text.
- A category page for each equipment type, such as exhaust fans, makeup air units and unit heaters, naming the brands you carry.
- A page for the area you serve, with your branches, delivery range and the brands you’re authorized to sell there.
Say “industrial ventilation”, never bare “ventilation”, on these pages. AI tools often read bare “ventilation” as hospital or home HVAC.

How we picked the agencies
We looked for agencies that show a case study from an industrial ventilation or HVACR distributor, supplier or manufacturer on their own site. None we found has published SEO numbers for a named HVACR wholesale distributor, so each entry says what kind of company its closest proof comes from. Then we checked for a published price and contract term.

The 6 best SEO agencies for industrial ventilation and HVACR distributors
1. Write Good Code
Best for industrial ventilation and HVACR distributors and reps with 5 to 100 people.
Write Good Code is a B2B digital marketing agency with published case studies from HVAC and industrial ventilation distributors. We write for the contractor and the plant engineer, never the homeowner. RWA Ventilation, a Chicago industrial ventilation supplier, spent 9 months with a nationwide agency and made zero sales. 6 months with us, it had more than triple the organic traffic.
Where Write Good Code falls short: we never work with 2 companies selling the same manufacturer’s products in the same territory. If a competitor of yours already works with us, we’ll say so on the first call.
Tired of agencies that pitch you “AC repair near me”? Our SEO services are built around model numbers, CFM ratings, stock and lead time.
2. OuterBox and TopSpot
Best for HVACR suppliers with large catalogs that want a mid-size team and a published price.
OuterBox is an Ohio agency founded in 2004, and it bought TopSpot, the Houston industrial agency, in 2024. For Coil Replacement, a Warren, Michigan company that has supplied HVAC coils since 1979, TopSpot built a new SEO-focused website. TopSpot reports organic traffic up 173% (2,125 visits against 777) and form submissions and phone calls up 196% (290 against 98).
OuterBox publishes its SEO packages at $2,000 to $7,000+ a month, billed month to month. TopSpot doesn’t publish its own prices.
Where OuterBox and TopSpot fall short: Clutch’s summary of TopSpot’s reviews mentions team turnover, with clients bringing new people up to speed. The Coil Replacement results come from a new website, not SEO alone.
3. Straight North
Best for airflow and ventilation manufacturers that sell to plant engineers and manufacturer reps.
Straight North is a Downers Grove, Illinois agency founded in 1997. For Kelair Dampers, a maker of industrial dampers that sells to plant managers, engineers and manufacturer reps, Straight North reports organic leads up 211% year over year and Google AI visibility up 425%. Its prices are public: SEO from $1,500 a month, and most clients pay $4,000 to $8,000.
Where Straight North falls short: its closest proof is a manufacturer, not a distributor. There have been complaints on Clutch about communication. It doesn’t publish a contract term.
4. JumpFly
Best for HVACR parts and equipment sellers with an online store.
JumpFly is a Hoffman Estates, Illinois agency founded in 2003. For an online HVAC equipment and parts store that sells to contractors and commercial and industrial buyers, JumpFly reports organic revenue up 48% and organic sessions up 23.8% in 2025 against 2024. The client isn’t named.
JumpFly doesn’t publish its prices or contract terms. Its Clutch profile lists a $5,000 minimum project.
Where JumpFly falls short: a reviewer stated that the gaps in price between its service tiers are large.
5. CI Web Group
Best for HARDI distributors that want websites and marketing for the contractors who buy from them.
CI Web Group is a Houston agency that has worked with home services and trades companies since 2006. It’s a preferred marketing partner of HARDI, the association for HVACR distributors, and it has a page for distributor catalog SEO.
CI Web Group doesn’t publish its prices or contract terms on its distributor or HARDI pages.
Where CI Web Group falls short: its distributor and HARDI pages show no distributor case study with numbers. Most of its published work is for contractors.
6. Geear
Best for ventilation equipment manufacturers that want a new website with SEO.
Geear is a Midlothian, Virginia agency founded in 2004 as WebStrategies. For a mining and industrial equipment manufacturer that makes ventilation systems, Geear reports 232 phone calls and 63 form submissions from organic search after its new site launched. The client isn’t named.
Geear doesn’t publish its prices or contract terms.
Where Geear falls short: its ventilation case study covers 2018 to 2020. Its clients also include credit unions and security companies, so industrial work is one part of its business.

Questions we get
What should an industrial ventilation distributor's product pages show?
An industrial ventilation distributor's product page should show model numbers, ratings and replacement models as text. For fans and blowers that means CFM, static pressure, voltage and motor horsepower. Add stock status and lead time, because a contractor can't get those from the manufacturer's site.
Can a ventilation distributor rank above the manufacturers it sells?
A ventilation distributor can rank above its manufacturers for their own product names. Knape Associates, a Houston industrial ventilation distributor, now shows up above the brands it distributes. The distributor's page wins when it answers the buyer's next question, such as fit, lead time and who installs it.
How much should an HVACR distributor spend on SEO?
An HVACR or industrial ventilation distributor should budget $1,500 to $2,000 a month for SEO to start, before ad spend. Most agencies on this list don't publish a contract term, so ask for the minimum in writing before you sign.
Does ChatGPT recommend HVACR distributors?
ChatGPT recommends HVACR distributors whose pages state what they sell, where and to whom. Each sentence on Hillco Distributing's site names Hillco, so ChatGPT can quote it. In our tests 5 weeks after launch, every time ChatGPT named Hillco, it named it first.
