We Help HVAC Pros
Capture Every Opportunity.
CallLock was built with a single goal: to end the missed call graveyard for home services. We believe no job should be lost because you were busy doing the work.
Why We Built CallLock
We saw a pattern in the HVAC industry: great technicians were losing thousands in revenue every month because they couldn't answer the phone while on a job.
Existing solutions like answering services were slow, expensive, and often just took messages. Customers don't want to leave a message—they want to book a job.
So we built CallLock. An AI that doesn't just take notes, but actually qualifies leads and books jobs directly into your calendar.
Speed to Lead
In HVAC, the first person to answer wins the job. We make sure that person is always you.
Reliability
Our AI doesn't have bad days, sick leave, or holidays. It's your most reliable employee.
Builder Focused
Every feature we build is designed to make life easier for field service professionals.
