The first hot week of summer is four times your normal call volume in three days. We Got The Call answers all of it at once, sorts the no-cool emergencies from the maintenance calls, and books what your techs can actually reach.
HVAC demand does not arrive evenly. It arrives as a heat wave or a cold snap, and on those days every competitor in your city is also unreachable. Whoever picks up the phone books the season.
A single office manager cannot take forty simultaneous calls. An agent can, every caller gets a first ring, not a queue, and nobody hears hold music while deciding to try the next company.
The questions your dispatcher would ask, in the order they would ask them.
