Residential HVAC
An AI receptionist for heating and cooling
The no-heat call at nine at night is answered by somebody within the hour, and it is rarely the company that missed it. What an assistant changes about that, and what it does not.

The short answer
An AI receptionist for a heating and cooling company answers the calls a cold snap produces when every engineer is already out, asks what is going on, and takes a name and a callback number. Where the business allows it, it books the visit against the real calendar. It is not a replacement for the text-back that already covers this trade: the text is what catches the calls the assistant did not take, and it is where an emergency word actually raises the lead.
What a recovered call is worth here
The jobs this trade quotes, with the value ranges the product uses when it estimates a pipeline. This is the only pack that carries them, and they decide whether any of this pays.

- Air qualitylow urgency
Why this trade specifically
- This is the only trade whose pack carries value ranges, and they are the argument for the whole thing: a system replacement is configured at six to eighteen thousand dollars against a maintenance call worth a fraction of it. The same answered phone catches both.
- Cold snaps and heat waves produce the calls and produce the reason nobody answers them. The busiest hour and the worst answer rate are the same hour, and seasonal hiring solves it for the season rather than for the call.
- A no-heat caller with a cold house is not leaving a voicemail. The company that picks up books the visit, and the two that did not receive a callback request that has already been answered elsewhere.
- When the assistant answers, what the caller said they need is matched against this trade's trigger list once the call ends, and a match raises the lead. Text replies are matched the same way, which is why the text that follows an unbooked call is not a formality: it is often where somebody first names the emergency.
- Recording is off. The carrier would record every call by default, and in a trade where the caller is often distressed and at home, that default is worth turning off rather than inheriting. A written record of what they said is kept instead.
What happens, in order
- A call arrives during a cold snap. Per number the business has chosen whether the assistant answers everything, only what it misses, or nothing at all.
- The assistant answers, says it is an assistant, and asks what is going on, which in this trade usually produces the words that matter in the first sentence.
- It takes a name and a number to call back on and reads them back before the call ends.
- Where the job is one the business marked bookable, it offers times that are genuinely free and books one for as long as that job is set to take.
- Where it is not, the caller's own description lands on the lead with their number, ready for whoever rings back.
- If nothing was booked, the text-back continues the conversation, and a reply naming an emergency word is escalated from there, including at two in the morning.
The call and the text do different jobs
Worth being precise about, because they are sold together and are not the same thing.
| The assistant on the call | The text that follows | |
|---|---|---|
| Who it reaches | Somebody who rang and waited | Somebody who rang and hung up, or was not booked |
| What it produces | A name, a number, what they need, and a booking if allowed | A reply in the caller's own words |
| Urgency flag | Raised when what they need matches this trade's words | Raised when a reply matches this trade's words |
| What it uses | Assistant minutes from the plan | A text from the plan's allowance |
The messages this trade sends
Real templates from the HVAC pack, with a business name filled in exactly as they would send.
missed call textback
This is Northgate Heating, sorry we missed your call. What is going on, and where are you? Reply here, or BOOK to book.
The same question the assistant asks out loud, in the channel that catches the calls it did not take. One segment, and no em dash: a single character outside ASCII would move the whole message into an alphabet where a segment holds 70 characters instead of 160.
emergency ack
Hi Dana, Northgate Heating has your message and is treating it as urgent. If this is a gas leak or emergency, call 911.
Sent when a reply matches an emergency word. It acknowledges and escalates and does not advise, because advising on a possible gas leak by text is not something software should do.
Questions
- Do I need this if I already have the missed-call text-back?
- Not necessarily. The text catches the caller who hung up; the assistant catches the caller who waited, and can book them. If your phone is answered most of the day and the problem is evenings and weekends, the text alone may be enough. The assistant is off until you switch it on either way.
- What happens on a no-heat call at two in the morning?
- The assistant answers if you have it switched on, asks what is happening, and takes a name and a number. If it is off, the caller gets a text inside about a minute instead. A reply naming an emergency word raises the lead immediately rather than waiting for opening time.
- Will it book a maintenance visit by itself?
- Only the jobs you marked bookable, and only with booking turned on. Maintenance is the usual first choice because it is routine and schedulable; a system replacement is usually left for a person, since it is a conversation rather than a slot.
- Is the call recorded?
- No audio is recorded. The carrier would do it by default and it is switched off deliberately, in a trade where callers are often distressed and at home. A written record of what the caller said is kept on the lead.
