Industry average
HVAC is brutally seasonal. The first day it hits 95, your phone explodes. You can't hire and train dispatchers fast enough, and temps don't know your business. Every unanswered call goes to a competitor who picked up.
Imagine the first 100-degree day hits and every single call gets answered, dispatched, or booked — without hiring a single temp.
What Phone Stack handles for you
Service call scheduling
Book appointments with urgency triage (no AC in August = same-day vs. routine maintenance).
Emergency dispatch
Route no-heat and no-AC emergencies to on-call technicians immediately.
Seasonal maintenance campaigns
Outbound calls for fall tune-ups, spring AC checks, filter replacements.
Estimate follow-up
AI calls back leads who received quotes but haven't committed. Close the gap.
After-hours routing
Emergencies dispatched immediately. Non-urgent calls logged for morning.
Customer satisfaction follow-up
Post-service calls to check satisfaction, upsell maintenance plans.
