What HVAC contractors use today.
And where Riley fits.

Four ways the phone gets answered, what each one costs, and the dispatch software you can keep.

You, between jobs

You can’t pick up with both hands on the work, and calling back later gives the customer time to call someone else.

Costs you the calls you can’t take

Voicemail

It takes a message. It can’t book the service call, give your hours or tell an emergency from a question.

Free, and it books nothing

An answering service

A live service is priced by the minute or by the call, so a busy month costs more. Ruby charges $3.45–$5.00 a minute; Smith.ai starts at $150 a month for 75 calls, then $2+ a call.

From $150 a month, then per call

Riley, on ThreeDay

Answers every call, 24/7, in 30+ languages. Books the service call, texts the confirmation and puts urgent calls through.

The dispatch software you already run? Keep it.

Riley doesn’t replace it. She answers the phone and books into your ThreeDay calendar with the hours and services you set, and you’re alerted for every booking, so your team adds it to your system the way they add any phone booking today. If you’d rather run the schedule in ThreeDay, it’s included.

Questions from HVAC contractors

How does she know what’s an emergency?+
You tell her. No heat in winter, no cooling in a heat wave, a gas smell, water on the floor: she puts those through to your on-call number and books everything else.
What does my tech get?+
A text with the address, the unit, what it’s doing and when the customer is home.
We already use ServiceTitan (or Jobber, or Housecall Pro). Do we have to switch?+
No. Riley books into your ThreeDay calendar with the hours and job types you set and alerts you for every booking. Your team adds it to your system the way they add any phone booking today, so nothing about it changes. If you’d rather run the schedule in ThreeDay, it’s included.
Can we keep our number?+
Yes. We port your number over, or you keep it and forward calls to her: all day, only after hours, or only when you can’t pick up.
How long does it take to set up?+
About three minutes for the self-serve plans: sign up, answer a few questions about your business, and your number is live. With Concierge we set it up for you and tune it on your real calls.
What does it cost?+
Front Desk is $149 a month with 300 minutes, and extra minutes are $0.35 each. It’s month to month, with 14 days free and no card to start. Concierge, where we set it up and run it with you, is $997 a month plus a one-time $1,500 setup.
