What it does for hvac contractors
For HVAC contractors, AllDayDesk separates bookable requests, staff-review requests, and simple questions.

HVAC Contractors FAQ
What happens with a no-heat call overnight?
You define the urgent rule. AllDayDesk's AI receptionist can ask whether the home has any working heat, capture the address and occupant risk, flag the call as urgent, and offer the first available emergency slot or transfer when live transfer is configured.
Can it handle calls about a frozen AC coil?
Yes. AllDayDesk's AI receptionist can recognize frozen-coil wording, collect the visible symptom, system location, thermostat setting, and service address, then book a diagnostic visit. It should not tell the caller what repair is needed. This keeps the answer clear while still guiding the caller toward a real appointment or callback.
Can it book tune-ups and maintenance plan visits?
Yes. AllDayDesk's AI receptionist can book tune-ups, collect system count, and answer plan questions from the details you provide. If plan pricing or member discounts are missing, it offers a callback or appointment instead of inventing terms. This keeps the answer clear while still guiding the caller toward a real appointment or callback.
What details does the receptionist collect for HVAC contractors?
It asks for the caller's name, preferred time, and the details needed for a real service visit. For this page, that means asking about whether the system is cooling at all, what thermostat temperature is set, whether the outdoor unit is running before it books or prepares a staff note.
How does it handle urgent HVAC contractors calls?
The receptionist follows the urgent-call rules you approve. It can flag calls that mention air handler, condenser, frozen coil, capture the address and context, and either book the next available time or prepare the call for staff review based on your settings.
What calendar can it use for bookings?
It can place appointments on the built-in calendar. If connected calendar availability has been set up for the account, it can use those open times; otherwise it collects preferred times so staff can confirm the appointment. This keeps the answer clear while still guiding the caller toward a real appointment or callback.
