Performance Max: Atlanta HVAC Leads in 2026

As a performance marketing specialist, I’ve seen countless campaigns struggle with fragmented strategies and inefficient spend. However, integrating Performance Max with agent traffic has fundamentally altered how we approach lead generation, especially for service-based businesses. Can a unified, AI-driven approach truly deliver superior results when human interaction remains paramount?

Campaign Teardown: “Local Services Connect”

I want to walk you through a recent campaign we executed for a regional home services provider, let’s call them “Local Services Connect.” Their primary goal was to increase qualified service calls for HVAC repair and installation, specifically targeting homeowners in the greater Atlanta metropolitan area. They had a robust in-house sales team (the “agents”) who converted inbound calls. The challenge was integrating the highly automated Performance Max campaign structure with their agent-driven conversion path.

Strategy: Bridging AI Automation with Human Touchpoints

Our core strategy revolved around leveraging Performance Max’s broad reach and automation while meticulously tracking and optimizing for the specific, agent-handled phone calls. We knew that simply driving traffic wouldn’t cut it; the traffic had to be highly qualified and ready to engage with a live person. This meant a heavy emphasis on call extensions, call-only ads, and landing page designs optimized for immediate phone contact.

• Budget: $15,000 per month
• Duration: 3 months (Q1 2026)
• Primary Goal: Increase qualified inbound service calls by 25%
• Secondary Goal: Achieve a Cost Per Qualified Lead (CPQL) under $75

Creative Approach: Hyper-Local and Problem/Solution Focused

For creative assets, we focused on two main pillars: hyper-local specificity and a clear problem-solution framework. We created distinct asset groups for key Atlanta neighborhoods like Buckhead, Midtown, and Alpharetta, using images and headlines that resonated with local landmarks or common issues in those areas (e.g., “Buckhead AC failing? Get same-day repair!”).

Our headlines addressed immediate pain points: “Furnace Broken? Get it Fixed Today!” or “New HVAC System Installation: Free Quote.” Descriptions highlighted urgency, local expertise, and special offers. Video assets were short (15-30 seconds), featuring local technicians speaking directly to the camera, emphasizing reliability and quick response times. Frankly, many clients underinvest in video for Performance Max, and that’s a mistake. A recent Statista report from 2025 indicated that video content drives significantly higher engagement rates across digital platforms, and we saw that play out here.

Targeting: Layering Signals for Precision

Performance Max’s strength lies in its ability to find conversions across Google’s entire ecosystem. Our targeting wasn’t about restricting reach, but rather providing the strongest possible signals. We uploaded several key audience signals:

• Customer Match Lists: Existing customer lists, segmented by service history (e.g., HVAC maintenance customers). This was our strongest signal.
• Website Visitor Lists: Retargeting users who had visited specific service pages but hadn’t converted.
• Custom Segments: Based on search terms like “HVAC repair Atlanta,” “furnace replacement Alpharetta,” and “AC installation cost.”
• Demographics: Homeowners, age 35+, within specific income brackets.

We also implemented location targeting for the entire Atlanta DMA, with bid adjustments for specific, high-value zip codes known for higher average order values. Critically, we configured our call extensions to use a third-party call tracking system, CallRail, which integrated seamlessly with Google Ads. This allowed us to attribute calls directly to the campaign and even tag them based on duration and agent feedback (e.g., “qualified lead,” “unqualified,” “spam”). Without this, Performance Max is blind to the quality of your phone leads, and that’s a recipe for disaster.

What Worked: Unpacking the Wins

The campaign delivered some impressive results. Over the three-month period, we saw:

• Impressions: 3.8 million
• Clicks: 58,000
• CTR: 1.53%
• Conversions (Qualified Calls): 205
• Cost Per Qualified Conversion (CPQL): $73.17
• ROAS (Return on Ad Spend): 4.2x (based on average service value)

The call-only ads within Performance Max were particularly effective, generating a lower CPQL ($65.20) compared to landing page conversions ($81.50). This validated our hypothesis that for urgent home services, people prefer to speak to an agent immediately. The machine learning model, given the strong conversion signals from CallRail, quickly learned to prioritize placements and creatives that drove these direct calls.

Our hyper-local creative assets also saw significantly higher CTRs (up to 2.1%) in their respective targeted neighborhoods, indicating strong message-market fit. For instance, the “Alpharetta furnace repair” asset group consistently outperformed generic “Atlanta HVAC” ads in the Alpharetta area.

What Didn’t Work: Learning from the Lapses

No campaign is perfect, and we certainly had our share of learning experiences.

• Initial Broad Keywords: We initially included some broader keywords in our custom segments like “home repair” or “plumbing services.” While Performance Max is designed to cast a wide net, these terms led to a noticeable increase in unqualified calls and irrelevant impressions in the first two weeks. Our agents reported a higher percentage of calls asking for services Local Services Connect didn’t provide.
• Generic Video Assets: A few generic, stock-footage-heavy video assets performed poorly. Their low engagement metrics (view-through rates under 10%) signaled to Google that they weren’t resonating, and their delivery was quickly throttled. I’ve always maintained that authenticity trumps polish, and this campaign was a prime example.
• Lack of Negative Keywords: My team initially relied too heavily on Performance Max’s automation without proactively adding negative keywords at the account level. This led to wasted spend on searches like “HVAC training courses” or “DIY furnace repair.” We quickly rectified this, adding over 100 negative keywords related to DIY, careers, and unrelated services. This is a common oversight; many marketers assume PMax handles everything, but you still need to guide it away from obvious irrelevance.

Optimization Steps Taken: Sharpening the Edge

Based on our findings, we implemented several key optimizations:

1. Refined Audience Signals: We removed the broader custom segments and focused exclusively on high-intent search terms and highly qualified first-party data. We also created a new custom segment based on users who had previously converted on competitor sites (using competitive search terms).
2. Enhanced Call Tracking Integration: We worked with Local Services Connect’s team to ensure their agents were consistently tagging call outcomes in CallRail. This provided even richer data for Google’s machine learning, allowing it to optimize for truly “qualified” calls, not just any inbound ring.
3. Aggressive Negative Keyword Management: We established a weekly review process for search terms (available through the “Insights” report in Google Ads) and continuously added irrelevant terms to our account-level negative keyword list. This alone reduced unqualified calls by nearly 15% in the second month.
4. Creative Refresh & A/B Testing: We paused all underperforming video assets and commissioned new, short-form videos featuring more authentic testimonials and behind-the-scenes glimpses of technicians. We also started A/B testing headlines and descriptions monthly, focusing on different value propositions (e.g., “speed” vs. “affordability” vs. “expertise”). This keeps the campaign fresh and prevents creative fatigue. According to Google Ads’ own best practices, regular creative refreshes are vital for Performance Max longevity.
5. Bid Strategy Adjustment: After collecting sufficient conversion data, we transitioned from “Maximize Conversions” to “Target CPA” with a target of $70 per qualified call. This allowed the system to more aggressively pursue our cost-per-acquisition goal.

Performance Metrics After Optimization (Month 3)

The optimizations paid off, particularly in the final month of the campaign teardown period:

The improvements were substantial. We not only exceeded the initial goal of a 25% increase in qualified calls but also significantly reduced the cost per qualified lead, demonstrating the power of continuous optimization within Performance Max. It’s not a “set it and forget it” solution, despite what some might claim. My experience tells me that without ongoing human oversight, even the smartest AI will eventually drift.

The key lesson here is that Performance Max, especially with agent traffic, demands a sophisticated blend of automation and human intelligence. You must feed it the right signals, monitor its outputs, and be prepared to intervene with strategic adjustments. It’s a powerful engine, but you’re still the driver, and you need to know how to read the dashboard and adjust the steering. Don’t be afraid to challenge the system; it learns from your feedback.

For any business relying on sales agents, integrating Performance Max effectively requires meticulous conversion tracking, continuous creative testing, and a proactive approach to audience signals. It’s a powerful tool, but its true potential is unlocked only when paired with strategic human input and a deep understanding of your customer journey.
