The Bureau of Labor Statistics' Occupational Outlook Handbook says plumbers are often on call to handle emergencies, and that HVAC technicians may be on call for emergencies and work overtime or irregular schedules during peak heating and cooling seasons. The trade is set up for the night call.
The phone is a different story. ServiceTitan looked at call booking by time of day across more than 3,000 trade businesses on its platform in 2022. Mornings had the highest booking rates. Large shops booked 61 percent of call leads at the peak and 21 percent after 6 PM. Small shops booked 26 percent at the peak and 9 percent after 6 PM.
- Large shops: 61 percent at the peak, 21 percent after 6 PM
- Small shops: 26 percent at the peak, 9 percent after 6 PM
- At both sizes, the evening rate is about a third of the peak
ServiceTitan's data is from 2022 and covers its own US and Canadian customers, not Colorado, and this note does not claim the emergencies arrive after 6 PM. It sets two facts side by side: the on-call schedule exists, and the evening call is the one least likely to turn into a job.
Try it tonight. At 6:30, call your own shop number from your cell phone and listen to what a customer hears, and how long it takes a person to pick up.
What ProxMedia does about it: an AI receptionist for plumbers and for HVAC companies that takes the 6:30 call, books the visit under your emergency rule, and reaches the on-call tech with the details instead of a voicemail.
