The Core Research

The MIT study that started it all

The foundational study was conducted by Dr. James Oldroyd at MIT in partnership with InsideSales.com. Researchers examined more than 15,000 leads and over 100,000 call attempts. The results were extreme.

Contact rate

100x

Leads contacted within 5 minutes were 100 times more likely to be reached than those contacted after 30 minutes.

Qualification rate

21x

The same 5-minute window made companies 21 times more likely to qualify the lead. The odds dropped sharply after the first 5–10 minutes.

Later analyses and industry benchmarks continue to support the same pattern: the value of a new inquiry decays very quickly.

Try It Yourself

The research points to one clear operational priority: shrink the time between the customer's call and a competent response.

The pattern shows up everywhere

Sub-1-minute advantage

Responding within 1 minute has been linked to dramatically higher conversion rates compared to even a short delay (commonly cited Velocify research).

First responder wins

In multiple studies, a large share of buyers end up doing business with the first company that responds.

Most companies are slow

The majority of companies still take far longer than 5 minutes to reply — leaving a clear opening for anyone who answers quickly.

Why It Matters Here

Why this hits HVAC, Plumbing & Electrical especially hard

Home service calls are high-urgency by nature. Customers usually contact more than one company — and the first one that answers and can schedule a technician often wins the job.

HVAC

No AC in extreme heat — customers call the first company that picks up and can schedule a technician today.

Plumbing

Water spreading across the floor — they call multiple plumbers and book the first one who answers.

Electrical

Panel issues and outages create urgent calls that usually go to whoever responds first.

After-hours & weekends make the gap even larger.

Many contractors miss these calls entirely or return them the next day — long after the customer has already booked someone else. Missed or slow responses don't just reduce conversion — in many cases they eliminate the opportunity completely.

Bottom Line

The first few minutes after the phone rings decide who gets the work.

The studies are consistent across more than a decade of data. The companies that systematically answer faster convert a higher percentage of the opportunities they already generate. ConvoPal AI answers in under 3 seconds — 24/7.
