The HVAC five numbers
- Daily call volume by source during peak season — Google local pack, Google Ads, Facebook, referral, repeat, emergency directory. Hourly granularity matters during heat waves.
- Booking rate per source — emergency-directory calls book differently than referral calls; track separately
- Average ticket per source — emergency tickets run 3-5x higher than tune-up tickets; channel mix dictates revenue
- Maintenance program enrollment rate — what percent of new customers convert to members within 12 months; the single most predictive number for HVAC long-term health
- Member retention rate — annual; should run 70-85%; below 60% and the marketing focus needs to shift to retention work
What gets added for Houston HVAC specifically
- Weather correlation — Houston freeze events, heat waves, hard rain cause distinct call-spike patterns; data tells you when to spike staffing
- Insurance vs cash mix — major HVAC repairs (compressor, heat exchanger) sometimes run through insurance; track separately
- Tune-up to repair conversion rate — what percent of tune-up calls reveal a needed repair; healthy is 15-25%
What to skip
- Generic GA4 engagement metrics
- Social media follower counts
- Aggregate-only call volume (loses peak/off-peak signal)
Tools
- Call tracking with multiple Houston-area numbers (per channel, per service line)
- GA4 + Looker Studio with weather-overlay view
- Service-management software pulls (ServiceTitan, FieldEdge, Jobber) for booking and ticket data
- Quarterly member retention review
Investment
$1,500-$3,500/month. Setup $2,000-$6,000 depending on call volume and integration count.

Frequently Asked Questions
- Why track weather correlation for HVAC?
- Houston freeze events and heat waves cause 4-8x call volume spikes. Knowing the pattern lets you pre-stage techs, advance-order parts, and capture the high-margin emergency work.
- Is hourly tracking really useful?
- During peak season, yes. Heat-wave call volume concentrates 9am-2pm. Pre-staging techs to that window changes booking capture significantly.
- What is a healthy member retention rate?
- 70-85% annual. Below 60% means marketing focus should shift from member acquisition to member retention. We have seen HVAC programs improve retention 15-25 points inside a year of focused work.
- Should we run separate reports for emergency and tune-up customers?
- Yes. They have completely different economics — emergency tickets are 3-5x larger and have lower repeat rates. Mixing them obscures both.
