The short answer
HVAC ads pay off when each campaign sells one kind of job.
Google Ads works for HVAC companies that run separate campaigns for repair, replacement and maintenance, raise and lower budgets with the weather, and measure booked jobs instead of clicks. HVAC demand is driven by temperature. The first hot week of summer floods the phones with no-cool calls, and the first cold snap does the same for furnaces. A good account is ready for both.
The three kinds of HVAC work behave like three different businesses. A repair caller wants someone today and picks whoever answers. A replacement buyer may get three quotes and take two weeks to decide, but the job is worth far more. A maintenance customer is price-aware and books ahead. One campaign can’t speak to all three, and one budget can’t tell which one is paying the bills.
Start by listing the work you want more of, the systems you service, the areas your techs cover and the hours someone answers the phone. Lithium’s HVAC marketing page shows how ads fit with your website and SEO.
Campaign structure
Four campaigns most HVAC accounts need.
Cooling repair
AC not cooling, AC repair near me, heat pump not working. Peak demand in hot weather. Push phone calls and run it during hours you can dispatch.
Heating repair
Furnace repair, no heat, furnace not turning on. The mirror of cooling repair for cold weather, with the same urgency and the same need for fast answers.
Replacement and installation
New AC, furnace replacement, heat pump installation, ductless mini split. Highest value per job and the longest decision. Give it its own budget so repair clicks can’t eat it.
Maintenance and tune-ups
AC tune-up, furnace inspection, maintenance plans. Lower cost per click and perfect for spring and fall, when repair demand drops.
If you do commercial HVAC, give it a separate campaign as well. A property manager searching for rooftop unit service reads different ads and fills out a different form than a homeowner with a broken furnace.
Inside each campaign, keep ad groups tight. “Heat pump installation” and “central air replacement” each deserve their own ads and their own landing page, because each searcher wants to see their exact job named back to them.
Weather and capacity
Move the budget with the thermometer and the schedule.
When a heat wave hits, repair searches spike and so do click costs, because every HVAC company in town is bidding. That is when your repair campaigns most need room in the budget. If they cap out by mid-morning, you disappear for the rest of the day. Watch the forecast and raise repair budgets before the spike, not after.
The other side of a spike is capacity. If your techs are booked out a week, a click from someone who needs cooling today is a click you can’t serve. Tell your ad manager when the board fills. Trim repair spend, shorten the ad schedule or switch the ad text to the first open day, and keep replacement and maintenance campaigns running, since those buyers can wait.
In spring and fall, shift money into tune-ups, maintenance plans and planned replacements. That keeps your techs busy between peaks and keeps the account’s conversion history alive. Our seasonal ad spend guide covers how to plan the year.
Keywords and negatives
Block the searches that will never book.
Start with phrase and exact match on the services you sell. Add broad match only after conversion tracking is feeding the account real booked-job data, because HVAC terms attract a lot of searches from people who will never hire a contractor. Read the search terms report every week for the first few months and add negatives as you go.
Searches worth paying for
- AC repair, AC not cooling, no heat
- Furnace or AC replacement, new HVAC system
- Heat pump or ductless installation
- HVAC company near me, HVAC in your town
- AC tune-up, furnace maintenance plan
Common negatives to block
- Car AC, auto AC, RV and window units you do not service
- Jobs, salary, HVAC school, certification
- DIY, how to, manual, reset, video
- Filters, parts, thermostats for sale
- Towns outside your service area
Location settings matter as much as keywords. Target the towns or ZIP codes your vans cover and show ads only to people in or regularly in that area. Check the addresses on booked jobs every month and pull the map in if out-of-area calls keep appearing.
Ads and landing pages
A repair click should land on a repair page.
Write each ad for the exact search. “AC not cooling? Same-day repair in Gresham” speaks to a sweating homeowner. “Heat pump installation with financing” speaks to a buyer comparing quotes. Add a call asset so mobile users can call from the ad, sitelinks to your main services, and callouts for things you deliver, such as upfront pricing, financing or a workmanship warranty.
Each ad group should send people to a page about that job. Google’s landing page guidance makes the same point: the ad text, keywords and page should match, and the call to action should be obvious.
A repair page needs a big tap-to-call button at the top, an honest service window, your service area and photos of your own techs and vans. A replacement page has to do more selling: the brands and system types you install, how your estimates work, financing if you offer it, warranty details and photos of finished installs. Review the service-business landing page guide for a full checklist.
Then answer the phone. Run repair campaigns only during hours someone picks up, or have after-hours calls covered. Lithium’s AI receptionist answers every call 24/7 for $179 a month with no contract, books appointments and can transfer a caller to a real person.
Budget and measurement
Judge the account by cost per booked job.
HVAC click costs depend on the season, how many competitors bid in your market, how urgent the search is and how well your ads match your landing pages. Repair clicks during a heat wave usually cost the most, and maintenance clicks in the shoulder seasons cost less. Replacement clicks are worth the most when they close.
A typical Lithium client spends $2,000 to $5,000 a month on ads, with management from $500 a month plus ad spend. Those are two separate bills: ad spend goes to Google, and management pays for the work on the account. The Google Ads cost guide shows how to set your number.
Track calls from ads, calls from the website and form fills from day one. Then go further: import booked and sold jobs from your field service software so Google can see which searches led to a small repair and which led to a full system install. Each month, compare spend with booked jobs and revenue by campaign. Add budget where the cost per booked job is lowest, and fix or cut the campaign where it’s highest.
