The Challenge: Historic Winter Storm

February 2024 - Phoenix's coldest temperatures in 30 years

The Perfect Storm

On February 22, 2024, Phoenix experienced its coldest temperatures in three decades. Overnight lows dropped to 28°F, causing widespread heating system failures across the metro area. What made this particularly challenging was that most Phoenix residents rarely use their heating systems, meaning many units failed when suddenly needed.

Phoenix HVAC's owner, Mike Chen, knew this would be their biggest test. In previous cold snaps, they had struggled with call volume, missing emergency calls and losing revenue to competitors who answered faster.

But this time was different. They had implemented Kestrel AI just 6 weeks earlier, specifically to handle after-hours and overflow calls. They were about to find out if it could handle the most extreme scenario possible.

Owner's Perspective

Mike Chen, Owner of Phoenix HVAC

"

I'll be honest—I was skeptical about AI handling emergency calls. But during that winter storm, Kestrel proved itself beyond any doubt. We handled 847 calls in 72 hours with ZERO missed calls. Our previous record was 180 calls in a week, and we missed about 30% of them.

What really impressed me was the consistency. At 3 AM on Friday, when we had 47 simultaneous calls, Kestrel handled every single one with the same quality as the first call of the day. A human receptionist would have been completely overwhelmed.

We generated $287,450 in revenue over those 72 hours. Without Kestrel, we would have captured maybe $37,000 based on our previous performance. That's $250,000 in revenue we would have lost to competitors.

The ROI was immediate and undeniable. Kestrel paid for itself 10x over in just one weekend.

Key Takeaways

Lessons learned from handling extreme call volume

AI Scales Instantly

Human receptionists can only handle 1 call at a time. During peak hours, Kestrel handled 47 simultaneous calls without any degradation in quality or response time. This scalability is impossible with human staff.

Consistency Under Pressure

The 847th call received the same quality service as the 1st call. AI doesn't get tired, stressed, or overwhelmed. This consistency is critical during emergency situations when customer anxiety is high.

After-Hours = Opportunity

287 of the 847 calls (34%) came during after-hours when a human receptionist wouldn't have been available. These after-hours calls generated $110,495 in revenue that would have been completely lost.

ROI in Extreme Scenarios

While day-to-day ROI is strong, extreme scenarios like winter storms prove the true value. The $250,000 in recovered revenue during one weekend paid for Kestrel for 10+ years.

Ready for Your Next Emergency?
