PPC for HVAC: Ads That Book Service Calls, Not Clicks
Updated: Sep 28
3 searches, typed by 3 homeowners in the same Central Florida town:
July, 4 p.m.: "ac not cooling"
A Saturday morning in March: "ac replacement cost"
An October evening: "ac tune up near me"
The first person needs a truck today. The second is weeks away from a decision worth far more than a repair. The third wants to book a slot and forget about it. One campaign can't serve all 3 well, and that's where most HVAC ad budgets leak.
PPC for HVAC works when you split Google Ads into 3 lanes by what the searcher needs: repair now, replace soon, and maintain on a schedule. Give each lane its own campaign, budget, hours, keywords, and landing page, move money ahead of Central Florida heat instead of chasing it, and judge every lane by booked calls and sold jobs, not clicks. Local Services Ads fit the repair lane in your core ZIP codes, and search campaigns give you control over replacements.
The Short Version: Our Verdict
Verdict: split repair, replacement, and maintenance into separate campaigns, budget by the heat calendar, and measure booked calls and sold replacements, not clicks.
Build 3 lanes. Repair, replace, and maintain each get their own campaign, budget, schedule, and landing page.
Move budget before the heat. Fund the repair lane ahead of a forecast heat wave, not after the phones light up.
Block the waste HVAC attracts. Job seekers, car AC searches, and parts shoppers burn budget fast.
Tell the truth about refrigerant. EPA's May 2026 change makes "replace now or else" ads misleading.
Count what pays. Track booked calls, booked estimates, and sold replacements as separate conversions.
Key Takeaways
Quick answer: HVAC clicks cost close to $10, Central Florida cooling demand dwarfs heating, and Google's tools reward planning ahead of heat waves.
Clicks and leads cost more than average. LocaliQ's 2025 benchmark puts Air Conditioning Installation and Repair at a $9.68 median cost per click and $127.74 per lead, against $90.92 per lead for home services overall.
Cooling is the whole game here. NWS Melbourne's 1991 to 2020 normals for Orlando show 3,452 cooling degree days a year and 525 heating degree days.
Heat waves are short events, and Google has a tool for them. Seasonality adjustments tell Smart Bidding about expected conversion rate changes, and Google says they work best for events of 1 to 7 days.
Your member list has limits. Any policy-compliant account can use Customer Match lists for exclusions and observation, but targeting a list requires 90 days of history and more than $50,000 in lifetime spend.
The refrigerant story changed in 2026. On May 21, 2026, EPA removed the January 1, 2026 installation deadline for R-410A equipment made or imported before 2025.
What Does HVAC PPC Cost in 2026?
Expect about $9 to $10 per click and $128 to $129 per lead at the median, then divide by the share of leads you book.
These are the most recent HVAC figures from LocaliQ's published table:
Category (LocaliQ, 2025) | Median cost per click | Median conversion rate | Median cost per lead |
Air Conditioning Installation and Repair | $9.68 | 6.56% | $127.74 |
Heating and Furnaces | $9.30 | 7.48% | $129.02 |
All home services | $7.85 | 7.33% | $90.92 |
Be careful with HVAC cost figures you find elsewhere. Pages ranking for this topic quote HVAC cost per lead anywhere from about $35 to $180, and several figures attributed to LocaliQ don't match its table. Treat any benchmark as a starting point and your own account data as the truth.
A lead still isn't a booked call. Divide cost per lead by the share of leads your office books. At $127.74 per lead, booking 60% of leads means about $213 per booked call, and booking 30% means about $426. Same ads, double the cost, decided entirely on the phone.
Why Should Repair, Replacement, and Maintenance Run Separately?
The 3 HVAC lanes differ in urgency, ticket size, sales cycle, and who takes the call, so shared budgets starve the most valuable work.
We call this the Three-Lane Account:
Setting | Repair lane | Replace lane | Maintain lane |
Searcher's mindset | "It's hot and it's broken. Who can come today?" | "My system is old. What will a new one cost?" | "I should get this checked before summer." |
Example searches | ac not cooling, ac repair near me, heat pump repair | ac replacement, new ac unit, heat pump installation | ac tune up, ac maintenance, hvac maintenance plan |
When ads run | Only when someone answers live and a tech can go out | All day for forms and estimate requests, with calls during office hours | Office hours, plus online booking around the clock |
Where to target | Your core drive-time ZIP codes | Your full service area | Your full service area |
Landing page | Call-first page with hours, diagnostic fee, and license number | Replacement page with system options, financing if offered, and an estimate request | Tune-up and plan page with what's included and online booking |
Who handles the lead | Dispatcher | Comfort advisor or estimator | Office scheduler |
Main conversion | Booked service call | Booked in-home estimate, then a sold replacement imported with its value | Booked tune-up or plan signup |
Conversion window | Default 30 days is fine | Longest available, up to 90 days | Default 30 days is fine |
Budget rule | Tech capacity this week | Open estimate slots and install crew capacity | Slow-week capacity |
Success metric | Cost per booked call | Cost per sold replacement | Cost per plan member |
Mixing the lanes causes 2 predictable problems. On the first hot afternoon, repair clicks drain a shared budget by lunch, and the replacement shopper who searches that evening never sees you. And Smart Bidding learns from whatever converts most often. Repair calls are fast and plentiful, so a blended campaign drifts toward them and away from the slower, bigger replacement sale.
How Should You Budget HVAC Ads Around Central Florida Heat?
Budget by the cooling calendar: build maintenance demand in spring, fund repair heavily from May to September, and push planned replacements in shoulder months.
Northern HVAC guides split the year between a cooling season and a heating season. Central Florida mostly has a cooling season and a shorter cooling season. NWS Melbourne's 1991 to 2020 normals for Orlando show 3,452 cooling degree days against 525 heating degree days a year, a normal July high of 92.0°F, and a normal December high of 73.8°F. That's why the budget calendar leans on cooling all year:
Period | What the weather is doing | Lane emphasis | Budget moves |
January to February | Mildest months, with occasional cold snaps | Maintain, Replace | Short heating and heat pump repair pushes on cold-snap days, plan renewals, and replacement estimates while crews have openings |
March to April | Warming ahead of peak heat | Maintain, Replace | Tune-up campaign at full budget, and planned replacements before the rush |
May to September | Peak heat and humidity | Repair first | Repair lane at full budget during staffed hours, with replacement ads focused on failed systems |
October to November | Still warm, easing off | Replace, Maintain | Shoulder-season replacement push, fall tune-ups, and plan signups |
December | Holiday slowdown | Maintain | Small budgets, plan renewals, and next year's planning |
Summer still produces replacements, mostly from failed systems found on repair calls. The shoulder months are when you can sell planned replacements while install crews have room.
The Heat-Week Playbook
When the forecast shows a heat wave coming, run this before the first hot day:
Confirm who's answering. Extend live phone coverage before you extend ad hours. An ad that rings voicemail pays for a customer your competitor keeps.
Raise the repair lane's budget first. Leave the replace and maintain lanes where they are.
Schedule a seasonality adjustment if you use Target CPA or Target ROAS. Google designed seasonality adjustments for expected conversion rate changes, recommends them for events of 1 to 7 days, and advises against using them for more than 14 days.
Pause tune-up promotions for the week. They compete for the same tech time as paying repair calls.
Check lost impression share (budget) every day. If the repair campaign is losing impressions to budget in the afternoon, it's out of money when demand peaks.
Update ad copy with real availability. "Next opening tomorrow morning" beats "same-day service" you can't deliver.
When ads hit their limits, your Business Profile still catches calls from the map results. Our guide to ranking in the Google Map Pack covers that side.
The Cool-Week Playbook
When a front cools things off, reverse it. Lower the repair lane's budget, turn tune-up campaigns back on, and follow up on replacement estimates while homeowners have time to decide. A cool week is the best time to book the maintenance visits that fill slow days and surface next year's replacements.
Which Keywords and Negatives Fit Each HVAC Lane?
Keep urgent repair phrases, replacement and install phrases, and maintenance phrases in separate campaigns, then block job seekers, car AC searches, DIY, and parts shoppers.
Lane | Keyword themes |
Repair | ac repair, ac not cooling, ac blowing warm air, air conditioner repair near me, emergency ac repair, heat pump repair, ac making noise |
Replace | ac replacement, new ac unit, hvac system replacement, heat pump installation, ac installation, ac replacement cost (a research-stage search, so bid lower) |
Maintain | ac tune up, ac maintenance, hvac maintenance plan, ac inspection |
HVAC terms attract a lot of searches that will never book. This starter list covers the ones that waste the most:
Negative theme | Examples to add |
Job seekers and training | hvac jobs, hvac technician salary, hvac school, hvac certification, epa 608 exam, apprenticeship |
Car air conditioning | car ac, auto ac, car ac recharge, car air conditioning |
Do-it-yourselfers | how to, diy, youtube, video |
Parts shoppers | parts, supply house, wholesale, capacitor price |
Equipment you don't service | window unit, portable ac, and commercial chillers if you're residential only |
Places you don't serve | cities outside your drive-time area |
Google's help pages note that negative keywords don't match close variants, so add plurals and synonyms yourself: "job" and "jobs," "school" and "schools." Then read the search terms report every week during peak heat, when new waste shows up fastest.
What Should HVAC Ads Say in 2026?
Each lane's ad should promise only what that lane delivers: a live answer for repairs, written options for replacements, and easy booking for tune-ups.
Responsive search ads take headlines of up to 30 characters and descriptions of up to 90. Here are starting points to adapt. Use only claims that are true for your company:
Repair lane | Replace lane | Maintain lane | |
Headline 1 | AC Repair in Orlando (20) | AC Replacement Estimates (24) | AC Tune-Up and Inspection (25) |
Headline 2 | Live Answer Until 10 PM (23) | Financing Options Available (27) | Join Our Maintenance Plan (25) |
Headline 3 | Licensed Local AC Techs (23) | Good, Better, Best Quotes (25) | Book Your Tune-Up Online (24) |
Headline 4 | FL Lic. CAC1234567 (18) | Heat Pump and AC Installs (25) | Priority Service for Members (28) |
Description 1 | AC not cooling? Call now. A licensed tech answers live and can dispatch today. (78) | Get a written replacement quote with system options, financing, and install dates. (82) | Beat the summer rush. Book a tune-up online and pick a time that works for you. (79) |
Description 2 | Diagnostic fee shown before we start. Serving \[area\]. FL License \[number\]. (74) | Ask how the refrigerant change affects your options. FL License \[number\]. (73) | Members get priority scheduling when the heat hits. See what the plan includes. (79) |
Put Your License Number in the Ad
Florida licenses air-conditioning contractors under Chapter 489 of the Florida Statutes, the same chapter that covers plumbers. Section 489.119(5)(b) requires the contractor's certification or registration number to appear in each advertisement, in any medium, as defined by board rule. In Google Ads, the simplest fix is a description line, a callout asset, or both, plus the number on every landing page. This is general information, not legal advice, so confirm the details with your attorney or the Construction Industry Licensing Board.
Handle the Refrigerant Question Honestly
Homeowners are hearing about refrigerant changes, and some ads use that to push panic replacements. Here's where things stand. EPA's 2023 Technology Transitions rule set a limit of 700 global warming potential for refrigerants in new residential air conditioning and heat pump systems starting January 1, 2025, which rules out R-410A in newly made systems. On May 21, 2026, EPA finalized a change removing the January 1, 2026 installation deadline for equipment made or imported before 2025, so that inventory can be installed until it runs out. HARDI, the HVACR distributors' association, notes that installed equipment can still be repaired.
So write ads and pages that inform instead of scare:
Don't write | Write instead |
"R-410A is banned. Replace your AC now." | "Ask how the refrigerant change affects your repair or replacement options." |
"Your old AC is about to become illegal." | "New systems use lower-impact refrigerants. We'll explain your choices." |
"Last chance before prices double." | "Get a written quote with repair and replacement options side by side." |
Honest copy also protects you. A homeowner who later learns the facts remembers who scared them.
How Do You Turn Maintenance Plan Members Into Ad Fuel?
Use your member list to exclude members from new-customer ads and observe how they perform, then reach them for upgrades by email and text.
Maintenance plan members are your best source of future replacements. Google's Customer Match lets you upload their contact details, but what you can do with the list depends on your account:
Customer Match feature | All policy-compliant accounts | Accounts with 90 days of history and more than $50,000 lifetime spend |
Exclusions | Yes | Yes |
Observation | Yes | Yes |
Targeting | No | Yes |
Manual bid adjustments | No | Yes |
Most small and mid-size HVAC companies land in the first column. That still gives you 4 useful plays:
Exclude members from your plan-signup and tune-up ads. There's no reason to pay a click to sell a plan someone already has.
Observe members in the repair lane. If members keep clicking your repair ads, they may not have your number handy. Put a service sticker on every air handler you maintain.
Remarket to replacement page visitors. People who viewed your replacement page but didn't request an estimate are worth a reminder about financing or a written quote.
Reach members through channels you own. Use tune-up notes, such as system age and condition, to decide who gets a replacement conversation by email or text. Upload to Customer Match only customers who gave you their contact details, as Google's policy requires.
Once your account meets the targeting threshold, you can show replacement offers to members whose systems are near the end of their life.
Where Do Local Services Ads Fit for HVAC?
Local Services Ads suit repair calls in your core ZIP codes, while search campaigns give you more control over replacements, schedules, and landing pages.
Google lists HVAC among the home services eligible for Local Services Ads, which charge per lead instead of per click and appear at the top of many local searches. Google announced that its Google Verified badge would replace older badges, including Google Guaranteed and Google Screened, starting in October 2025. Responsiveness affects where you appear, so the Heat-Week rule about live answers applies here too.
For HVAC, the fit is simple. LSAs catch urgent, nearby repair calls. Search campaigns let you choose keywords, hours, ZIP codes, and a dedicated replacement page with an estimate form. We've compared cost, control, and fit for trades in our guide to Local Services Ads vs Google Ads for contractors.
How Do You Track Booked Calls and Sold Replacements?
Track a separate conversion for each lane, import sold replacements with their value, and give replacement conversions a longer window than repair calls.
The tracking stack itself, including call reporting, minimum call length, enhanced conversions for leads, and importing booked jobs from your field service software, is the same one we laid out in our guide to PPC for plumbers. What changes for HVAC is how you set up the conversion actions:
Conversion action | Lane | Primary or secondary | Window |
Booked service call | Repair | Primary for the repair campaign | 30 days (default) |
Booked in-home estimate | Replace | Primary until sold data flows reliably | 30 days or longer |
Sold replacement, with revenue value | Replace | Primary once you import it consistently | Longest available, up to 90 days |
Booked tune-up | Maintain | Primary for the maintenance campaign | 30 days (default) |
Plan signup, with value | Maintain | Primary or secondary | 30 days (default) |
The window matters because Google's default click-through conversion window is 30 days, and Google lets you set it from 1 to 90 days depending on the conversion source. A replacement decision can stretch past a month between the first click, the estimate, and a financing approval. With a 30-day window, those sales never get credited to the ad that started them, and your replacement lane looks worse than it is.
Review 3 numbers for each lane every week in peak season: the share of leads booked, cost per booked call or estimate, and lost impression share from budget.
Frequently Asked Questions
Quick answer: set budgets from capacity by lane, pay for after-hours clicks only when staffed, and treat Facebook and Performance Max as supporting tools.
How much should an HVAC company spend on Google Ads each month?
Work backward from capacity, one lane at a time. Estimate how many extra repair calls, estimates, or tune-ups your team can handle, then multiply by your cost per booked call for that lane. Start with the lane that has the most open capacity, measure your real costs across a full heat cycle, and move money toward the lane with the lowest cost per sold job.
Is it worth paying for after-hours AC repair clicks?
Only if a live person answers and someone can go out or book a first-thing appointment. An after-hours click that reaches voicemail pays for a customer who calls the next company on the list. If you can't staff nights, stop the repair lane at closing time and let the replacement and maintenance lanes keep collecting online requests overnight.
Do Facebook ads work for HVAC companies?
They work better for planned work than for emergencies. Use them for tune-up offers, plan signups, and replacement financing, shown to homeowners in your service ZIP codes. Nobody scrolls social media hoping to find AC repair while sweating. LocaliQ reports that home services businesses running both Facebook and search ads saw cost per lead drop 3% to 29%, so treat Facebook as support for search.
Should an HVAC company use Performance Max?
Start with Search campaigns, where you choose keywords, see search terms, and keep the 3 lanes separate. Performance Max spreads ads across Google's channels with less direct control over where they appear. It works best once booked calls and sold replacements import reliably, because it optimizes toward whatever you tell it counts. Add it later as a test, not as your foundation.
Is heating worth advertising in Central Florida?
A little, at the right moments. Orlando's normals show 525 heating degree days a year against 3,452 cooling degree days, so heating demand is small and arrives in short cold snaps. Keep heat pump and heating repair keywords in the repair lane, raise budgets for the few cold days that bring calls, and don't run a year-round heating campaign at summer weight.
How long does HVAC PPC take to pay off?
The repair lane can bring calls within days of launch if phones are staffed. The replacement lane takes longer, because estimates turn into sales over weeks and Smart Bidding needs conversion data to learn. Judge each lane over a full heat cycle, not a single hot or cool week, and use the longer conversion window so replacement sales get credited correctly.

Sources and Methodology
This playbook draws on LocaliQ benchmarks, Google Ads documentation, NWS climate normals, EPA rule coverage, and Florida statutes, all checked September 29, 2026.
How We Researched This
Reviewed the top results for "ppc for hvac" and "google ads for hvac companies 2026" on September 29, 2026. Page one was HVAC and home services agencies, ad tools, and a field service software vendor. Cost-per-lead claims across those pages ranged from about $35 to $180, several without a primary source. We went to LocaliQ's published table directly.
None of the ranking pages tied budgets to a warm-climate cooling calendar, explained Customer Match limits for maintenance lists, set a longer conversion window for replacements, covered EPA's May 2026 refrigerant change, or applied Florida's license number rule to AC contractors.
Opened each cited source the same day. Benchmarks are medians across many advertisers, so your market will differ.
The Three-Lane Account, the heat budget calendar, the Heat-Week and Cool-Week playbooks, the ad examples, the refrigerant copy table, and the conversion action table are RedFork frameworks and illustrations, not Partner results. Company figures (500+ websites, 800+ businesses helped, 4.9-star Google rating, Wix Certified, founded 2014) are RedFork-reported.
This page covers paid search for HVAC. The shared tracking stack, the full Local Services Ads comparison, and Map Pack rankings each have their own RedFork guide, linked where each topic comes up. Nothing here is legal advice.
