Dael.ai is an artificial intelligence answering service designed specifically for HVAC and plumbing businesses. Its primary function is to answer every call that a shop’s team cannot take, call new leads back within 60 seconds, and book appointments directly onto the business’s calendar. The service operates on a flat monthly fee of $297, with the option to cancel after two months. Dael.ai is trained on each shop’s specific services, pricing, service area, and hours, and it identifies itself as an AI during calls. The tool includes five core capabilities. It answers all calls missed by the team, day and night. It responds to every new lead by calling back in under 60 seconds. It books jobs by asking the right questions for HVAC and plumbing work and placing the appointment on the calendar. A forthcoming feature, Revive, will automatically follow up with old estimates and customers who went quiet, looping back to the booking process. Finally, Dael.ai provides a monthly one-page report detailing calls answered, jobs booked, and revenue recovered. The system also hands off emergency calls to the shop’s on-call technician. Typical use cases include handling after-hours calls when systems break and callers are ready to book, preventing slow callbacks that let paid leads go cold, and managing busy seasons such as heat waves when phone volume exceeds team capacity. The service is intended to recover revenue from missed calls; the website illustrates that a single recovered job per month can cover the subscription cost. Dael.ai is also listed as serving real estate businesses, though the primary focus is on HVAC and plumbing shops. The service uses a zero-miss protocol and references a vendor figure from ServiceTitan indicating that AI voice agents book 70 percent of calls they handle, though this is not a measure of missed callers.
