For independent HVAC service companies in Dallas–Fort Worth

Every call answered. Every lead captured.

Hartwell is an AI phone receptionist for residential and commercial HVAC companies. It answers your calls 24/7 — especially after hours and when your team is busy — gets the caller's details, and books or routes the job so no customer is left with voicemail.

What Hartwell does

Answers every call, 24/7

Nights, weekends, holidays, and overflow during busy hours. Callers reach a friendly receptionist instead of a voicemail box.

Captures the job details

The caller's name, service address, the issue (for example, no cooling or no heat), and their preferred appointment time.

Books or routes the job

Following your rules, Hartwell books the visit or routes the request to the right person on your team.

Emails you a call summary

After each call, the owner receives an email summary with the caller's details and what they need.

Follow-up texts, with consent

If the caller agrees during the call, Hartwell sends a follow-up text with next steps, a callback time, or a booking link. Message and data rates may apply. Message frequency varies. Reply STOP to opt out, HELP for help. See our SMS Terms and Privacy Policy.

Who it's for

Hartwell is built for small and mid-sized independent HVAC service companies in the Dallas–Fort Worth area that handle residential and commercial heating and cooling calls. If you're an owner-operator or a lean team that can't always get to the phone — on a job, after hours, or during a summer rush — Hartwell makes sure the call still gets answered and the lead gets to you.

How it works

  1. 1

    A customer calls your business

    When you can't pick up — after hours, overflow, or any time you choose — Hartwell answers the call.

  2. 2

    Hartwell takes the details

    It asks for the caller's name, address, the problem, and a preferred time, then books or routes the job according to your setup.

  3. 3

    You get the summary

    You receive an email call summary, and the caller can get a follow-up text if they said yes during the call.
