Customer Stories: The Switch from VAPI
Real HVAC companies who migrated to Kestrel
"Spent 60 hours building with VAPI. Kestrel was better in 48 hours."
"I'm technical, so I thought VAPI would be perfect. But after 60 hours of setup, I still didn't have my CRM integration working properly. Switched to Kestrel and they had everything running in 2 days. Plus, their HVAC-specific features are way better than what I built."
"VAPI was cheap until I calculated my time investment."
"VAPI looked cheaper at $800/month vs. Kestrel's $499. But I was spending 8-10 hours every month maintaining it, fixing bugs, and updating prompts. That's $1,000+ in my time. Kestrel saves me money AND time, plus it works better with zero maintenance."
