When an HVAC company tells me it generated 150 leads last month, the total number only tells me so much. I want to know how many were repair calls, how many were maintenance opportunities, and how many were homeowners actively considering a system replacement.
That distinction becomes especially important when the company’s goal is growing installation revenue. I regularly see HVAC companies combine repair and replacement opportunities into one lead total, then evaluate their marketing primarily through overall lead volume and cost per lead. A campaign can look great on paper because it produces inexpensive leads while generating very little of the work the company actually wants.
Repair and replacement customers are both valuable, but they represent different customer journeys, different economics, and often different sales processes. HVAC companies should market and track them separately while still building a system that allows repair customers to become maintenance and replacement customers over time.
The Short Version
If you own or manage an HVAC company, these are the four distinctions I would start with:
- Separate repair and replacement campaigns whenever possible. Search intent and acceptable acquisition costs are different.
- Stop judging performance only by cost per lead. A more expensive replacement opportunity can be much more valuable than a cheaper repair inquiry.
- Track leads through booked jobs and revenue. Knowing that Google Ads generated a lead is not enough.
- Do not abandon repair marketing just because you want installations. Repair customers can become recurring customers and future replacement opportunities.
The objective is not to decide whether repair or replacement is “better.” It is to understand what each part of the business contributes and make sure your marketing supports the revenue mix you are trying to build.
Repair and Replacement Customers Are Not Searching for the Same Thing
A homeowner whose air conditioner stops cooling during a hot afternoon usually has an immediate problem. They may search for AC repair, look at reviews, confirm that a company serves their area, and call whoever appears capable of getting someone to the house quickly.
A replacement customer can enter the buying process differently. Their system may still be operating, but it could be aging, breaking down repeatedly, becoming expensive to repair, or struggling to keep the home comfortable. That homeowner may spend more time researching contractors, equipment, warranties, financing, efficiency, installation quality, and total cost before requesting an estimate.
Those differences should influence how the customer is marketed to.
A repair campaign might focus heavily on high-intent searches involving specific problems and immediate service needs. Replacement campaigns should be built around homeowners showing clear installation or replacement intent, such as searches involving AC replacement, HVAC installation, furnace replacement, heat pump installation, or a new HVAC system.
There is also an important overlap between these two groups. A repair customer can become a replacement customer. That happens every day in the HVAC business. A technician arrives for what the homeowner believes is another repair and determines that the age, condition, or cost of repairing the equipment makes replacement worth discussing. ServiceTitan’s HVAC contractor benchmarks actually include generating replacement opportunities from service calls as a technician performance metric.
This is one reason I would never advise an HVAC company to view repair and replacement as completely isolated businesses. They need separate marketing and reporting, but there should also be a clear path between them.
Build Campaigns Around Intent, Not Just "HVAC"
One of the more common problems I find when reviewing HVAC advertising accounts is campaign structure that is too broad. A company creates an HVAC campaign, builds a handful of ad groups, adds a large list of keywords, and sends most of the traffic to the same general landing page.
That structure can generate leads, but it makes it much harder to control what type of work the advertising is producing.
I prefer separating repair and replacement campaigns because doing so gives us more control over budget, keywords, ad messaging, landing pages, conversion data, and acceptable cost per lead. A replacement campaign should be allowed to tolerate a different acquisition cost than a repair campaign if the economics justify it.
Keyword structure should also get more specific than many HVAC accounts I review.
Instead of putting AC repair, furnace repair, HVAC replacement, heat pump installation, and general HVAC terms together, group searches around closely related customer intentions. Google’s own Search keyword guidance recommends grouping keywords by themes and making sure the ads within each group are relevant to those searches. Google also recommends reviewing the actual search terms triggering ads and using negative keywords when the traffic does not match what the advertiser wants.
That is particularly important in HVAC because one broad keyword can represent several very different customers.
The landing page should continue that same thought. Someone searching for an emergency repair should not necessarily receive the same message as someone researching a $10,000 or $20,000 system replacement. Repair customers generally need fast confirmation that you can solve their problem, while replacement customers may need more information about installation, financing, warranties, equipment, reviews, and what to expect during an estimate.
The search, ad, landing page, and desired job should all make sense together.
A Higher Cost Per Lead Is Not Necessarily a Worse Lead
Cost per lead is one of the first numbers most business owners ask about, and I understand why. It is simple, easy to compare, and appears in almost every marketing report. The problem is that CPL does not tell you what was purchased.
Imagine that one campaign generates repair leads for $100 while another generates replacement opportunities for $300. If you only look at lead cost, the repair campaign appears to be three times more efficient.
That may be completely wrong from a business standpoint.
A $300 lead for a homeowner considering a full HVAC replacement can be a reasonable investment if the company has the sales process and margins to support it. ServiceTitan’s contractor KPI framework uses a 25% to 35% closing range for marketing-generated replacement opportunities as a performance benchmark for comfort advisers. The same framework puts technician-generated replacement opportunities much higher, at 75% to 85%, which also demonstrates how much the source and quality of an opportunity can affect sales performance.
Using the lower end of that marketing-generated benchmark, four $300 replacement leads would cost $1,200 and statistically represent roughly one sale. That does not mean every HVAC company should happily pay $300 per replacement lead. Margins, sales performance, market conditions, competition, capacity, and the actual quality of the opportunities still matter.
It does show why calling a $300 lead “too expensive” without knowing what happened after the lead came in is not useful analysis.
The job values are also fundamentally different. ServiceTitan’s contractor benchmarks use an HVAC service ticket target of at least $375 and a replacement installation target above $7,700. More recent ServiceTitan analysis of completed 2025 residential installations found an average invoiced amount of $17,040 among qualifying residential HVAC installations processed through participating customers on its platform. ServiceTitan notes that this dataset is not nationally representative and that project values vary substantially by location and scope.
That is exactly why I do not want an HVAC owner choosing campaigns based on which column has the lowest CPL.
Repair and Replacement Leads Should Be Evaluated Differently
The goal is not to assign one universal value to every repair or replacement lead. It is to build reporting that reflects how the business actually makes money.
| What to Measure | Repair / Service | Replacement |
|---|---|---|
| Primary customer need | Diagnose or restore heating and cooling | Replace aging, failed, or inefficient equipment |
| Typical sales cycle | Often shorter | Often requires consultation, estimate, and follow-up |
| Lead value | Lower immediate ticket in most cases | Higher potential immediate revenue |
| Marketing goal | Book and complete profitable service calls | Generate qualified replacement appointments |
| Useful KPIs | Booked calls, completed jobs, ticket value, acquisition cost | Qualified leads, estimates, close rate, sold revenue, acquisition cost |
| Long-term opportunity | Maintenance, repeat service, reviews, future replacement | Installation revenue plus future service relationship |
Track Leads Through Revenue, Not Just the Form Submission
The best HVAC campaign analysis happens when marketing data and sales data can be looked at together.
A report saying Google Ads generated 80 leads gives me a starting point. A report saying those 80 leads included 50 repair opportunities, 20 replacement opportunities, five maintenance inquiries, and five unqualified leads gives me substantially more information.
Now take it one step further.
How many repair calls were booked? How many jobs were completed? What revenue came from them? Did any generate maintenance agreements or replacement opportunities? For replacement leads, how many were qualified? How many estimates were scheduled? How many appointments were completed? What was the closing rate? How much sold revenue came from that campaign?
That is where marketing performance starts becoming useful to a business owner.
Unfortunately, attribution is an area where I see many HVAC companies struggle. Phone calls may not be categorized correctly, CRM records can be incomplete, form submissions get counted as leads before anyone determines whether they were legitimate, and marketing reports sometimes tell a completely different story than the company’s actual sales numbers.
Fixing attribution is often more valuable than adding another campaign.
Google Ads provides tools specifically for moving beyond the initial web lead. Google’s qualified lead and converted lead goals allow businesses to send deeper funnel information from a CRM or internal sales system back into Google Ads. Google describes qualified leads as inquiries that have been further qualified offline and converted leads as leads that reached a defined later-stage conversion, such as a sale or closed deal.
That gives the advertising system better information than simply telling it that a phone call or form submission occurred.
For an HVAC company, the tracking might eventually look something like this:
| Marketing Data | Sales Data |
|---|---|
| Google Ads | Repair or Replacement |
| Campaign | Qualified or Unqualified |
| Keyword / Search Theme | Appointment Booked |
| Landing Page | Estimate Completed |
| Call or Form | Sold or Lost |
| Cost | Revenue |
Not every contractor needs that entire system on day one. Even consistently classifying incoming opportunities as repair, maintenance, or replacement is a major improvement over putting every call into a single lead total.
Repair Calls Can Become Some of Your Best Replacement Opportunities
There is a temptation to focus almost entirely on replacements because the revenue numbers are larger. If an HVAC owner tells me they only want replacement leads, I usually push back on that idea. A healthy HVAC company needs a complete customer system.
Repair customers create immediate service revenue, but they also create relationships. A homeowner who has already allowed your technician into their home knows your company, has experienced your service, and may already trust your recommendation when the system eventually needs to be replaced.
This does not mean I would use vague lifetime-value projections to justify a repair campaign that is losing money. Customer lifetime value matters, but I consider it a supporting metric rather than the first number I use to determine whether the marketing is working.
What matters is creating a system for keeping good customers.
A homeowner who received a repair should not disappear from the marketing database until the next emergency. That person can enter appropriate maintenance reminders, seasonal service campaigns, email follow-up, service agreement marketing, and other retention programs.
This is an area where I think many HVAC marketing plans are incomplete. Agencies know business owners want new leads, so the natural recommendation is another campaign with another monthly advertising budget. There is often far less attention paid to building a repeat-service system around customers the company already spent money to acquire. That can leave a lot of value sitting in the database.
Not Every Marketing Solution Needs Another Monthly Ad Budget
Digital advertising, SEO, email automation, CRM integrations, and remarketing can all play useful roles in an HVAC marketing strategy. They should not make us forget simple ways to keep the company visible to an existing customer.
A service sticker is a good example. A large, readable company sticker placed appropriately on the HVAC system gives the homeowner a phone number to call the next time there is a problem. It may sit there for years, and the business does not have to pay for another Google click simply to remind an existing customer who serviced the equipment.
The same thinking can apply to maintenance reminders, leave-behind materials, refrigerator magnets, direct mail to existing customers, and properly timed email or text communication. The right mix will vary by company, but the principle is the same.
HVAC marketing should include customer acquisition and customer retention.
If you continually pay to acquire customers but have no meaningful system for staying in front of them afterward, you are forcing the marketing department to replace customers the business already earned.
What I Would Review Before Increasing an HVAC Marketing Budget
Before an HVAC company spends more money trying to generate leads, I would look at the previous 60 to 90 days and separate the numbers by service category.
Start with these questions:
- How many repair, maintenance, and replacement leads did we actually generate?
- Which marketing sources produced each type?
- What percentage of those leads became booked appointments?
- How many completed jobs or estimates resulted?
- What was the close rate for replacement opportunities?
- How much sold revenue came from each lead category and source?
- Are repair customers entering a maintenance or follow-up system?
- Are technicians consistently identifying legitimate replacement opportunities?
That exercise usually tells you far more than another report showing impressions, clicks, and an overall CPL.
If replacement revenue is behind target, the answer may be more replacement advertising. It may also be poor campaign structure, broad keywords, weak landing pages, bad attribution, low booking rates, insufficient sales follow-up, or a comfort adviser who is struggling to close marketing-generated opportunities.
If service technicians have open capacity, the problem may be on the repair side instead.
Marketing should follow the needs of the business rather than forcing every part of the business into one lead-generation strategy.
Build the Marketing Around the HVAC Company You Want to Become
Repair leads and replacement leads are both valuable, but they should not disappear into the same spreadsheet column.
Separate the campaigns where it makes sense. Separate the reporting. Track what happens after the lead comes in. Pay attention to booked jobs, closing rates, sold revenue, and customer retention instead of automatically rewarding whichever campaign generates the cheapest form submissions.
At the same time, keep the connection between service and replacement intact. Some of the best future installation opportunities are already inside the homes of your repair customers.
If you are trying to decide where to put the next dollar of your HVAC marketing budget, start by determining exactly what the last dollar produced.
At Nuvo Agency, that is how I prefer to evaluate home-service marketing. The website, paid advertising, SEO, CRM, lead tracking, sales process, and follow-up should give the business owner a clearer picture of where revenue is actually coming from.
If your current reporting stops at “we generated 150 leads,” there is probably more to the story.
