01 — The Challenge

Feast or Famine in the Phoenix Desert

Precision Comfort HVAC had survived for years on referrals and a modest Google Ads budget that performed well in summer and died in winter. When summer AC season hit, they were overspending on broad keywords and still missing calls to faster-responding competitors. When temperatures dropped, budget sat largely unspent with no off-season strategy.

They had no call tracking in place, which meant they could not tell which campaigns were generating real booked appointments versus people who called, heard hold music, and hung up. Their campaigns counted every outbound call as a conversion, artificially inflating numbers and hiding the actual cost per booked job.

Emergency service searches like "AC not working" and "HVAC emergency near me" were lumped into the same ad groups as installation searches like "new AC unit cost." These two audiences have completely different purchase intent and require separate bidding logic, messaging, and landing pages to convert efficiently.

02 — Our Approach

Time-Smart, Caller-First Campaign Structure

We rebuilt the account around HVAC buyer behavior rather than keyword volume, creating distinct campaign types for each job category and deploying bidding logic calibrated to when Phoenix homeowners actually call for help.

Tactic 01

Dayparting for Emergency Calls

Analyzed call data to find peak emergency intent windows. Raised bids 45% during weekday mornings and evenings when AC failures spike. Reduced spend overnight when no one answers calls.

Tactic 02

Geo-Radius Bidding

Applied bid multipliers tied to drive time from dispatch. Higher bids within 15 miles where techs respond under an hour. Reduced bids at service area edges where response time hurt close rates.

Tactic 03

Call-Only Emergency Campaigns

Launched dedicated call-only campaigns for emergency keywords. Removed the landing page entirely, putting a tap-to-call button directly in search results. Required 60-second minimum call duration for conversion credit.

Tactic 04

Seasonal Budget Scaling

Built a 12-month budget calendar with pre-planned increases in March and August ahead of peak seasons. Shifted off-peak savings into maintenance plan awareness campaigns to smooth off-season revenue.

03 — The Results

Month-by-Month Performance Climb

Because HVAC results are tied to seasons, reporting tracked against the same month the prior year. Every month outperformed the prior year comparison from month two onward.

Month 1 — Foundation

Call Tracking Installed, True Baseline Established

Discovered that only 38% of counted conversions were actually booked jobs. Real cost per booked job was $89, not the $34 their previous reporting showed. Reset all benchmarks from verified data.

Month 2 — Restructure

Campaigns Split by Job Type

Emergency repair, installation, and maintenance tune-up campaigns each received separate budgets and ad groups. Dayparting activated on emergency campaigns. Cost per booked job dropped to $67 within 30 days.

Months 3 to 4 — Call-Only Launch

Emergency Call Volume Responds

Call-only campaign launched for emergency keywords. Emergency call volume increased 94% versus same period prior year. Cost per booked emergency job reached $44. Install inquiries up 18%.

Months 5 to 8 — Peak Season

Budget Scaled Into Phoenix Summer

Pre-planned budget increase executed in April. Emergency call volume hit 218% above prior year during peak summer months. Geo-radius bidding kept technician dispatch profitable at higher volume. Install jobs up 44%.

Month 14 — Sustained Performance

Cost Per Booked Job Holding at $31

Cost per booked job stable at $31 across all job types in the account second year. Maintenance plan campaign added a recurring revenue stream reducing off-season revenue volatility by 31%.

Frequently Asked Questions

HVAC campaigns need pre-planned seasonal scaling rather than reactive adjustments. In Phoenix, AC repair demand spikes from April through September. Pre-loading budget increases 4 to 6 weeks before peak season captures intent at lower CPCs before competitor bids escalate. During off-season months, shifting budget toward maintenance plan keywords smooths revenue and keeps campaign history active for the algorithm.

For emergency service calls, call-only campaigns outperform standard search ads because they remove the landing page step and put a dial button directly in front of someone whose AC is broken right now. For installation and maintenance bookings where the customer needs pricing before committing, standard search ads with dedicated landing pages produce better close rates and higher average job value.

HVAC companies waste budget on DIY intent keywords like how to fix AC, AC troubleshooting, and HVAC parts. Broad match terms like "air conditioner" or "heating system" pull in appliance shopping and informational searches with no service intent. Competitor brand names without a strong differentiating offer also produce low conversion rates. A thorough negative keyword list built before launch prevents this waste from day one.

Emergency HVAC calls cluster in predictable windows: weekday mornings when people wake to a broken system, and evenings when they come home to an overheated house. Raising bids 40 to 50% during these windows while reducing overnight spend, when calls go to voicemail anyway, improves efficiency without sacrificing overall call volume or reach.

Both matter, but calls must be the primary conversion event for emergency service campaigns. Set a minimum 60-second call duration filter to eliminate accidental dials and robocalls from your conversion count. For installation and maintenance campaigns, form submissions integrated with a CRM that records booked appointments provide the cleanest signal for Google to optimize toward actual revenue.
