Case Study: How ProComfort HVAC Cut Cost-Per-Lead 38% Without Cutting Ad Spend
ProComfort HVAC runs a 14-technician operation across three metros and spends $12,400/month on paid search, Facebook lead ads, and Yelp. Their cost-per-booked-service call had crept up to $187 over 18 months — a familiar squeeze in HVAC as bid competition rose. Instead of raising budget, they attacked the leak: after-hours leads dying in the inbox. Here's what changed.
The diagnostic
Pulled 90 days of lead timestamps. 41% of leads arrived between 6 PM and 8 AM.
Of those after-hours leads, only 22% converted to booked service calls (vs. 51% for business-hours leads).
Root cause: next-morning callbacks. By 8 AM, the homeowner had usually booked someone else or the emergency was resolved.
The fix
Deployed a 24/7 AI chat widget on the main site and all landing pages. Widget qualifies (system type, symptom, urgency), quotes the service-call fee ($119), and books straight into ServiceTitan.
Facebook lead ads routed through Zapier into the same widget qualification flow before hitting the CRM.
SMS to on-call dispatcher for anything flagged 'no heat' or 'no AC' in extreme weather.
60-day results
After-hours lead-to-booking rate: 22% → 58%.
Total booked service tickets/month: 68 → 92 (+35%).
Cost per booked service call: $187 → $115 (-38%).
Ad spend: unchanged at $12,400/month.
Install lead volume up 22% because service techs upsold visits that were only booked because of after-hours capture.
What the owner said
'We assumed we needed more ad budget. We actually needed to stop wasting the leads we already paid for. The widget captures the 2 AM AC-out call that used to go to voicemail. That's a $6,500 install we would have missed every week.' — Dana R., Owner.
