An AI receptionist for HVAC. Built for the first hot week.
HVAC calls arrive in waves. The first heatwave or cold snap fills the phone while every tech is already on a job. An AI receptionist can take the routine requests in that wave, ask the questions that sort urgent from not, and put the urgent ones in front of your on-call tech.
These are the calls a pilot is planned around. For each one: what the receptionist asks and records, and the point where a person takes over.
7:40 pm, office closed
No cooling, vulnerable occupant
The receptionist
Asks whether anyone at the property is elderly, unwell or very young, and confirms the address and callback number.
Then
Marked urgent and sent straight to the on-call tech, as in the sample call below.
Tuesday morning, both techs out
Spring tune-up request
The receptionist
Takes the equipment type, approximate age, address and preferred days for a maintenance visit.
Then
Lands in the office queue as a request. Nobody is promised a time until dispatch confirms one.
Saturday afternoon
Replacement quote
The receptionist
Notes the system age, the reason for replacing, the property type and whether the caller wants an in-home estimate.
Then
Goes to whoever runs estimates. Pricing questions are left for them.
During a busy week
Existing customer, repeat fault
The receptionist
Recognises the caller as existing if they say so, records which visit they are calling about and what has happened since.
Then
Flagged for the tech who did the last visit or the service manager.

Tether · AI receptionist
Thanks for calling. The team is out on jobs right now, so I'm taking calls for them. How can I help?
Caller
Our air conditioning stopped blowing cold this afternoon. It's really hot upstairs.
Tether · AI receptionist
Sorry to hear that. Is this your home or a business, and is anyone at the property who's vulnerable to the heat?
Caller
It's our home. My mom lives with us and she's eighty-two.

Thank you. I'm marking this as urgent and passing it to the on-call technician now. Can I confirm the best number to reach you?

Illustrative. In a pilot, what Tether records and who it alerts are agreed and tested with you first. It only books appointments where a tested booking connection is in place.
A pilot starts by writing these lists down with you. They are a starting point for HVAC companies, not a fixed product.

Answering service for contractors
An answering service, or an AI receptionist?
A staffed answering service suits HVAC companies whose after-hours calls are mostly emergencies that need a calm human voice. An AI receptionist suits the routine calls in between: it asks the same HVAC questions every time and sends a structured request to you or your office, and it hands the emergencies to a person. Many contractors use one for each. See the full comparison.

Common questions
HVAC AI receptionist, answered.
Can it dispatch a technician?
Not by itself. It can send an urgent request to the on-call tech by text or call, if that route is set up and tested in your pilot. A person decides who goes and when.
What about a gas smell or a carbon monoxide alarm?
The receptionist is set up to tell the caller to leave the building and contact the gas company or 911, then pass the call to a person. It does not try to troubleshoot.
Can it quote a price for a new system?
No. It collects what the estimator needs and leaves pricing to them. If you publish a diagnostic or call-out fee, it can repeat that approved figure.
How much does an AI receptionist cost for HVAC companies?
It is quoted per pilot. One-off setup covers the call flow, approved answers and handoff. Voice usage (telephone minutes, speech and model processing, number rental) is billed by use and priced separately, and depends on how many calls it takes and how long they last.
Is Tether available now?
Tether, the MoxiSync receptionist, is in development and offered through guided early-access pilots. There is no public live calling or self-service signup, and availability depends on your region and phone routing.
