The AC quits at 9pm and the call goes to voicemail.
The fix →Missed-call text-back fires the second a call goes unanswered, so the homeowner sweating through a summer night hears from you in seconds instead of dialing the next company. Owners think they answer 97% of calls. They actually answer 66% (ServiceDirect). The system catches the ones you would have missed, day or night.
