HVAC answering service

Every call answered. Every job booked.

Vallo is the AI answering service built for HVAC businesses. It answers your calls, handles your FAQs, and books jobs — even while you're on a roof.

Live in minutes. No credit card.

A missed HVAC call is a job your competitor booked.

When you're on a roof or under a unit, the phone rings and goes unanswered. Most callers don't wait. They move to the next HVAC number on their list. Whoever picks up gets the job. An HVAC answering service fixes that. Vallo answers every call in your name, handles the conversation the way you would, and books the job before the customer moves on.

After every call, a full summary lands in your inbox — recorded, transcribed, and ready to read — so nothing slips.

Common questions about HVAC answering services.

How is Vallo different from a traditional HVAC answering service?

Traditional answering services use human receptionists who follow a generic script. Vallo is trained specifically on your HVAC business — your services, your area, your pricing. It answers around the clock at a fraction of the cost of a human service, and it books jobs directly into your calendar instead of just taking messages.

Will my customers know it’s not me?

Most don’t notice. Vallo answers with your business name and handles calls naturally. For anything that needs a personal touch — complex estimates, existing customer issues — it transfers directly to you.

What if it books me for a job I can’t take?

Vallo only books based on your real availability. You control the calendar — it books into open slots, not over existing jobs.

How much does an HVAC answering service cost?

Vallo starts under $100 a month. One missed AC repair call during busy season covers months of Vallo. Most HVAC businesses see ROI in the first week.
