100 Free HVAC Leads in 10 Minutes Using OpenClaw and Apify
An OpenClaw agent scraped 100 HVAC leads from Google Maps, scored each one for AI opportunity, and auto drafted personalized outreach emails in Gmail from a single voice command in under 10 minutes.
The Strategy
Most AI agency owners spend money on ads or hours on manual prospecting to find clients. There is a faster way. An OpenClaw agent connected to Apify's Google Maps scraper can generate 100 targeted leads in under 10 minutes with emails, phone numbers, opportunity scores, and personalized outreach drafts ready to send, all completely free. The system works by scraping businesses from Google Maps in a specific niche and location, then using web fetch to crawl each company's website and analyze their current tech stack and AI readiness. Zach Babiarz built this for his AI automation agency targeting HVAC companies in Phoenix, Arizona, but the same flow works for any industry and any geography. What makes this powerful is the end to end automation. The agent does not just find leads. It scores each one on a scale of 1 to 10 based on how much they would benefit from AI services, drafts personalized emails referencing specific details from their website, and saves everything as ready to send drafts in Gmail using Google's Himalaya CLI. For businesses without a listed email, it generates custom contact form messages as a backup outreach strategy. The entire stack is free to start. Apify gives $5 of scraping credit per month, which covers roughly 250 leads at two cents each. OpenClaw is open source. Claude writes the outreach emails. Gmail handles delivery. The only ongoing cost is the LLM tokens for analysis and copywriting.
How It Works
Create a free Apify account, navigate to integrations, and copy the API key. Give this key to your OpenClaw agent so it can access the Google Maps scraper programmatically.
Configure the OpenClaw agent with a lead generation skill that defines your target niche, geographic area, and the data fields to collect: business name, phone number, email, website URL, and physical address.
Issue a single command to the agent specifying the number of leads and target market. For example: "Get me 100 HVAC leads in Phoenix, Arizona." The Apify Google Maps scraper pulls matching business listings and returns structured data.
The agent automatically uses web fetch to crawl each lead's website, analyzing their online presence, existing tools, and gaps where AI services could add value.
Claude AI scores each lead on a 1 to 10 scale for AI opportunity based on the website analysis. A 9 or 10 indicates clear gaps that your services could fill immediately.
All lead data is written to a Google Sheet or Apple Numbers spreadsheet including business name, phone, email, website, opportunity score, and a personalized note about what specific AI services they need.
For leads with a publicly listed email address, the agent uses Google's Himalaya Gmail CLI to draft personalized outreach emails and save them as labeled drafts in Gmail, ready for review.
For leads without email addresses, the agent generates custom contact form messages referencing specific details from their website as a backup outreach channel.
Review all drafts as the human in the loop. Edit subject lines and copy as needed, then send. The free Apify tier covers approximately 250 leads per month and additional leads cost roughly two cents each.
Results
The system generated 100 HVAC leads in Phoenix in approximately 5 to 10 minutes from a single voice command. Roughly half of the leads had email addresses publicly listed on their websites. All 100 leads received AI opportunity scores and personalized outreach messages. Gmail drafts were auto created and organized with labels, ready for manual review and sending. The entire run used only free tier Apify credits with no ad spend.
Our Take
We think this is the most practical OpenClaw use case we have covered so far. Lead generation is the one thing every agency needs and most people still do manually or pay for through ads. Automating the entire pipeline from scraping to scoring to drafting outreach into a single voice command is a genuine competitive advantage, not a parlor trick. The AI opportunity scoring is a smart detail that prioritizes outreach by actual likelihood of conversion instead of blasting everyone equally. The free economics make it accessible to anyone just getting started. The limitation is that this produces cold outreach, not warm inbound leads, so conversion rates will depend entirely on the quality of the emails and follow up cadence. Legal compliance around mass outreach also requires attention depending on your jurisdiction. Best suited for AI automation agency owners who need a steady pipeline of local business prospects without spending on ads.
