Key takeaways
- Search ads earn their keep when you need control: specific services, hours, areas and replacement campaigns that LSA cannot target.
- Repair and replacement belong in separate campaigns, with separate budgets and separate landing pages.
- Budgets should follow the weather and your capacity, not a flat monthly number.
- Track every call and form to a booked service call in your field service software.
Google Ads for an HVAC company work when each campaign is built around one kind of job, shown only in the areas and hours you can serve, and measured on booked service calls rather than clicks. Done that way, search ads cover the gaps that Local Services Ads and SEO leave, especially high-ticket replacements and the first days of a heat wave.
When Google Ads pay off for HVAC companies
Search ads pay off when you need to control what you pay for. Here is how they compare with the other two ways HVAC companies get found on Google:
| Situation | Search ads | Local Services Ads | SEO and Maps |
|---|---|---|---|
| Heat wave or cold snap, schedule has gaps | Strong: turn up budget the same day | Strong, if you answer every lead | Helps, but you cannot speed it up |
| Selling replacements, heat pumps or ductless | Strong: separate campaigns and pages | Limited control over job mix | Strong over time, with pages built for them |
| New service area you want to grow into | Good: target by ZIP code | Depends on your settings and eligibility | Slow to build far from your address |
| Schedule full for the week | Pause or cut, instantly | Lower the budget | Keeps running at no media cost |
| Shoulder season, tune-ups and memberships | Works for maintenance offers | Fewer urgent leads | Strong for plan and tune-up searches |
Search ads are weaker when your phones are not covered, when you have no page for the service you are advertising, or when you cannot see which clicks became jobs. Fix those first, or the budget leaks no matter how good the campaign is.
The LSA column in that table is changing for HVAC. Google has started to run Local Services Ads from inside Google Ads, as pay-per-lead Performance Max campaigns, and HVAC is one of the trades in the first phase (Google's transition notice). Once both sit in one account, comparing them on cost per booked call gets easier. The Local Services Ads guide for HVAC companies covers that side.

Campaign setup we use
- Separate campaigns for repair and replacement. Repair searches are urgent and high volume. Replacement searches are fewer and worth far more. Mixed together, repair clicks eat the budget.
- Ad groups by service: AC repair, furnace repair, heat pumps, ductless, system replacement, maintenance plans and indoor air quality, each pointing at its own landing page.
- Call-first ads for emergencies, with call assets, scheduled to the hours someone answers.
- Targeting by ZIP code from your dispatch history, not a radius drawn around the shop.
- Negative keyword lists from day one (negative keywords): HVAC jobs and training, DIY and parts searches, manufacturer support lines, and services you do not run.
- Seasonal switching prepared in advance: heating ads ready before the first cold night, cooling ads ready before the first hot week.
- Landing pages matched to each ad group, built for a phone. See Google Ads landing pages for HVAC companies.
Budget and tracking
Set the budget by the season and your capacity, and judge it by cost per booked service call.
Budget. Spend follows the weather. Peak summer and winter days can absorb far more budget than a mild week in April, and a full schedule makes extra clicks worthless. Set a base budget, a heat-wave plan and a rule for pausing when the board is full. Replacement campaigns run steadier through the year, because aging systems get replaced in every season.
Tracking. Before spend goes up, every call path needs a counter: call assets and a forwarding number on the site (call tracking), and booking and form completions set up as conversion actions (conversion tracking). The last step happens in ServiceTitan, Housecall Pro or Jobber, where each tracked lead is marked booked, run or sold. Report repair and replacement separately: a campaign with a higher cost per lead can still win if it sells systems.
How it works
- Assess. We audit your current account, or your search demand if you have none, and look at how calls are answered and tracked today.
- Prioritize. We decide which campaigns to run first, usually emergency repair in the coming season and a replacement campaign alongside it.
- Execute. We build the campaigns and landing pages in accounts you own, and get tracking working before spend increases.
- Measure. We report booked service calls, replacements sold and cost per booked call, then move budget to what produces jobs.
How VETS Growth Marketing helps
We run Google Ads for HVAC companies in an ads account in your name, scoped as a project with dates and a target cost per booked call. There is no long-term contract, and reporting comes from your own job data, not from click counts. Book a growth consultation and bring access to your account. We will show you where the spend is leaking.
