THE AI SHORTLIST BLOG
17 guides for HVAC owners, built on 2026 data. What a lead actually costs, which numbers decide your job count, and how ChatGPT, Google AI Mode, Perplexity and Gemini choose which company to recommend. Every figure names its source so you can check it yourself.
Five numbers decide your job count: answer rate, booking rate, cost per booked job, lifetime value and shortlist share. Four of the five are free to fix, and the top quartile books roughly twice as many jobs from the same phone.
Four assistants, four completely different source lists. One cites Google 95.5% of the time. Another cites it 0.1% of the time. Here is what each one actually reads before it names a company.
The average HVAC shop answers 68% of calls and books 42% of those. The top quartile answers 91% and books 66%. Only 8% of average shops track booking rate per person, which is why the gap stays open.
Branded search $34. Local Service Ads $51. Performance Max $72. Non-branded search $149. Every HVAC channel in 2026, with the book rate that decides what a lead really costs you.
Cost per lead is the number the sales rep shows you. Cost per booked job is the number that pays your payroll. The spread between the best and worst channel is over three times.
The average HVAC customer is worth $15,340. On a maintenance plan, about $47,200. Top operators attach a plan to 30 to 50% of installs. Median shops attach under 10%.
Only 30% of homeowners schedule preventative maintenance, so 70% of your market is uncontracted. Plan members carry 2.4 to 3.1 times the lifetime value of a one-time customer.
Marketing to lapsed customers returns $8 to $12 per dollar. New customer acquisition returns $3 to $4. Most contractors still put 70 to 80% of the budget into strangers.
ACCA recommends about 10% of gross revenue for growth, and contractors spending 12% or more see net profit rise from 5% to 9%. The budget by stage, and the two things to fix before you raise it.
Google Business Profile signals are 32% of local pack weight, reviews 20%, on-page 15%. The strongest single factor is your primary category, and changing it takes five minutes.
Expertise.com showed up in 32.1% of ChatGPT home-services answers. Yelp showed up in 0.6%. If you are picking where to spend an afternoon, pick by the data, not by brand name.
When ChatGPT cited a contractor's own site it took the homepage 37.4% of the time and a blog post 1.2% of the time. That one gap should change what you build next.
An AI assistant matches the words in your reviews against the words in the question. “Fixed our AC the same day in Frisco” can be matched. “Great service!” cannot.
47% of consumers will not use a business with fewer than 20 reviews. 31% only use 4.5 stars or higher. 74% look for reviews from the last three months. Three numbers decide whether you are in the running.
Yelp is cited in the text of only 0.6% of ChatGPT home-services answers. But 34% of the rated business cards on ChatGPT's map linked to a Yelp page. Both numbers are true, and they mean different things.
45% of consumers ask AI. An answer names two or three companies. 72% of buyers look at three or fewer businesses before deciding. Run those three numbers together and the loss has a price tag.
Jobber's data puts HVAC last among the trades for response speed. Reply in five minutes and a lead is 21 times more likely to qualify. Winning the AI answer is only half the job.
