Two homeowners own the same twelve-year-old central air conditioner. One of them, on a mild April evening, types "how long does an AC unit last" into Google and reads three articles with a glass of iced tea. The other types "AC replacement near me" on a July afternoon, after the unit groaned, rattled and quit with the thermostat reading 86.
Same equipment. Same street, for all we know. To an HVAC company, these are two different searches worth two very different amounts, and Google Ads will happily charge you for either one. This chapter lines up heating and cooling searches from browsing to buying, and argues that a new account's first dollars belong at the buying end, where people already have the phone in hand.
The numbers come from Google's Keyword Planner, pulled for the whole US, with a check against our example market, Indianapolis. Your city's volumes will be smaller or larger. The order they fall in is the same everywhere.
A Search About a High Electric Bill Is Four Stages Away From "AC Repair Near Me." Each Stage Needs a Different Ad.
Marketers describe a buyer's path in five stages of awareness. HVAC searches line up along it neatly, and the monthly US volumes show how many people stand at each step:
- Unaware. The homeowner has a symptom but hasn't connected it to the system. "Why is my electric bill so high" draws 6,600 searches a month. An aging air conditioner is one possible cause among several, which is exactly why this search sits at the top.
- Problem aware. They know something is wrong with the equipment. "Furnace making noise" draws 210. "Upstairs hotter than downstairs" draws 170.
- Solution aware. They are weighing fixes. "How long does an AC unit last" draws 8,100, "heat pump vs furnace" 6,600, and "new AC unit cost" 5,400.
- Service aware. They are pricing the job or comparing equipment. "AC replacement cost" draws 9,900, "best AC brand" 3,600, and "Carrier vs Trane" 1,300.
- Most aware. They want a company now. "AC repair near me" draws 201,000 a month, "HVAC near me" 165,000, "furnace repair near me" 74,000, and "AC replacement near me" 14,800.
At every rung, the ad has a different assignment. At the top you create awareness. One step down, you earn interest. In the middle, you help someone decide. At the bottom, you give a ready buyer a reason to call you instead of the next listing. An ad that tries to do all four jobs does none of them well, which is why the stages matter before a single keyword goes in.
In heating and cooling terms, the message changes like this:
- Unaware: a short video on what quietly drives a summer power bill up, with the AC as one suspect.
- Problem aware: a page that explains what a banging or squealing furnace usually means, and when it's a call instead of a wait.
- Solution aware: an honest repair-or-replace comparison that a homeowner can read without being sold.
- Service aware: replacement price ranges, financing terms and what's included in an install.
- Most aware: a same-day time window, a phone that gets answered, and the reviews to prove both.
Bidders Pay About 10 Times More for "AC Replacement Near Me" Than for "How Long Does an AC Unit Last?"
For every search, Keyword Planner gives a low and a high estimate of the bid it took to show above the organic results, based on past auctions. Look at how that range moves as the searches get closer to a purchase:
- "How long does an AC unit last": $0.25 to $7.36.
- "AC replacement cost": $3.31 to $20.10.
- "AC replacement near me": $15.51 to $84.33.
- "AC repair near me": $13.98 to $100.00.
The high end of the estimate climbs more than tenfold from the lifespan question to the replacement search. Nobody coordinated that. Thousands of HVAC advertisers, bidding against each other, simply learned which searches turn into invoices and which ones turn into reading.
One exception is worth a look. "Furnace making noise" is a problem-aware search, yet its top-of-page estimate reaches $74.62. A furnace that bangs at night tends to produce a phone call fast, and the auction knows it. Stages are a map, not a law. The bid data is how you check the map against what buyers actually do.
"AC Repair Near Me" Draws 201,000 Searches a Month. The Questions Above It Draw a Few Thousand.
In some industries the ready-to-buy searches are a thin sliver at the bottom of a giant pile of research. Heating and cooling flips that. The bottom of the funnel is also the biggest part of it.
Across the US, "AC repair near me" alone draws 201,000 searches a month, and "furnace repair near me" another 74,000. The lifespan, cost and comparison questions above them run from about 5,400 to 9,900 each. The same shape holds in our example market at a smaller scale: in Indianapolis, "AC repair near me" and "HVAC near me" each draw about 2,400 searches a month, while the question searches draw between 50 and 110.
That is good news for a new account. You do not have to choose between volume and intent. The searches with the most buyers in them are also the searches with the most people in them, so starting at the bottom does not starve the account of clicks.
Check it in your own market before you trust it. In Keyword Planner, set the location to your service area, enter one search from each stage, and read two columns: average monthly searches and the top-of-page bid range. If your near-me searches are the biggest and the most expensive, your market looks like ours. If a question search is unusually expensive, find out why before you write it off.
A Dead AC in July and a Planned Replacement in April Are Both Buyers. They Need Different Ads.
The most-aware stage holds two very different people.
The first has no cooling or no heat right now. Of the 221 low-star heating and cooling reviews we read for this guide, 42 came from homeowners who had lost AC in a heat spell or heat in a cold snap, many with a baby, an aging parent or a health condition at home. This person wants a time window and a phone that gets answered. A clever headline about efficiency ratings is noise to them.
The second is replacing a system on purpose, often after a tech told them the old one was done. That buyer is cautious, and with reason: 63 of those same 221 complaints described pressure to replace, and in 29 of them a second company fixed the problem for far less. This person wants options, a straight explanation and an estimate they can compare.
Both searches belong in a first campaign. They do not belong in the same ad, or on the same landing page. Chapter 4 builds the ad groups that keep them apart, and Chapter 14 deals with the fact that one of them peaks in July and the other in January.
Search Catches the Buyer. Demand Gen and Performance Max Wait Until Search Has Taught Google Who Buys.
Each Google channel fits a stage of the funnel, and the order you switch them on matters as much as the fit.
Search catches the bottom: someone typed exactly what they want. We call the opening campaign Isolation: buyer searches you already trust, on exact match, every bid set by you. Its partner, which we call Exploration, comes later. It opens up the match types after enough real calls and bookings have piled up for Google to study.
For an HVAC company, the first Isolation list is short and plain: AC repair, furnace repair and HVAC company searches with "near me" or your city attached, plus replacement searches if you install systems. Every one of them sits in the most-aware stage. Chapter 5 builds that list from real competitor sites and Keyword Planner data.
The map catches the same buyer in a different place. Your Business Profile and location assets put your address, hours and rating next to your ads. Local Services Ads show up on the map too; in this guide they wait their turn and arrive as a side-by-side test after Search is filling the schedule. Chapter 12 explains why.
Demand Gen reaches people higher up, before they search for a company, across YouTube, Discover and Gmail. Google is also moving its Display ads into Demand Gen. Google pegs a sensible Demand Gen budget to the bid: tenfold the target cost per acquisition, at minimum, for campaigns bidding that way. That rule alone says who the channel suits: an account that already knows what a new customer costs.
Performance Max runs across nearly all of Google's inventory at once. It waits until the account shows steady volume, about 30 quality conversions a month. For most accounts that means months six or seven. Bigger, higher-spend accounts get there sooner.
Research Searches Only Pay Off for Budgets Big Enough to Wait. Every Other HVAC Account Starts at "Near Me."
We open at the buying end of the funnel. An HVAC shop that can fund all five rungs at once may start higher; few can.
The reasoning is the same one Chapter 1 set up. Every later campaign learns from conversions. Bottom-of-funnel searches produce conversions fastest, because the person was already looking for a company. Spend the first months there, track every call and booking, and the account builds the history that Exploration, Demand Gen and Performance Max need to work.
Starting at the top on a small budget is like heating the attic first. It feels productive, the money disappears, and the living room is still cold.
Upper-funnel work is not useless. It just pays later. A homeowner who reads your article on AC lifespans this April may remember your name in July, and Chapters 10 and 11 build the campaigns that do that on purpose.
Next: An AC Repair Averages About $400. A New AC Averages Nearly $6,000.
You know which searches to buy first, and Chapter 1 set up the tracking that tells Google which of them paid. Chapter 3 puts a dollar figure on a click when one homeowner needs a $400 repair and the next one needs a new system.
Every chapter in the rollout, from the first tracked call to seasonal budgets and new-system ads, is on the guide's home page.
In the HVAC accounts we handle through our Google Ads management, month one's money goes to near-me searches and nothing above them. Building your own? Pull Keyword Planner's top-of-page estimates for five of your searches and see where the money already is.
