📞 (650) 789-8801 — Call NowWater damage doesn't wait for business hours. When a customer's basement is flooding, they call the first plumber who picks up. If it's not you, it's your competitor.
Burst pipes, sewer backups, no hot water — AI answers every call, day or night.
Job type, location, urgency, callback number — on your phone in about 30 seconds.
A single after-hours emergency AC repair pays for months of Call Den.
The AI knows the difference between a dripping faucet and a flooded basement — and flags priorities accordingly.
Flagged as high priority. AI asks what the symptoms are, whether it's cooling at all, and how urgent it is.
Gas or electric? How old is the unit? How many square feet?? AI qualifies so you show up with the right parts.
AI detects urgency from keywords like "carbon monoxide," "no heat," "elderly in home" — instant priority flag.
Non-emergency jobs captured and sent anyway — thermostat upgrades, filter changes, seasonal tune-ups. A lead is a lead.
From the moment you miss a HVAC call to the moment you call back.
You're under a sink, up to your elbows in a rough-in, or asleep at 3 AM. The call goes to Call Den instead of voicemail.
"Thanks for calling [your company]. How can I help?" The voice handles panic, interruptions, and follow-up questions like a real dispatcher.
What's happening? Where's the property? Is water still running? How soon do you need someone? Emergency keywords like "no heat" or "AC out" trigger an instant high-priority flag.
Name, job, location, urgency, phone number — on your phone before the caller finishes leaving a message. Scannable. No app.
You know exactly who called, what's broken, and how bad it is. Dial the number while they're still standing in front of the problem.
