Stop losing HVAC jobs to missed calls.
Qasten builds a custom AI receptionist for HVAC companies that answers every call, reply to customer questions, and books an appointment on the right person's calendar while the customer is still on the line. Live in 48 hours.
7-Day Risk-Free Pilot • No payment required
You're losing money to missed calls.
In HVAC, speed wins. When a call hits voicemail during a heat wave, after hours, or while your team is on another line, customers don't wait. They call the next company until someone answers. Qasten fixes that by making sure every caller gets answers and a booked slot immediately.
Answers calls after-hours, weekends, and during peak-season spikes.
Pickup guarantee.
Answers questions and books the appointment in the same call - no phone tag.

Why use an AI voice agent in HVAC?
Because your best leads don't come in neatly - they call. And if you don't answer fast, you don't get the job.
- Answer common questions (service area, availability, pricing ranges, brands/equipment, warranties, membership plans - based on your rules)
- Collect the right details (issue description, urgency, address, access notes, equipment type)
- Route to the right person (service vs. maintenance vs. install/estimate - based on how you run your team)
- Book directly on the calendar so the customer leaves the call with a confirmed appointment
The first company that answers usually gets the job.

Your Questions, Answered
What exactly is the HVAC Voice Agent?
It's a custom AI phone agent built for HVAC companies. It answers inbound calls, responds to customer questions, gathers the right info, and books an appointment directly on the right calendar.
Do I need a CRM?
Not necessarily. If you have one we integrate seamlessly with it. If you don't have one, we can run everything from your calendars. If you want more visibility, we'll set up a lightweight call/lead log so you have a simple system without adopting a full CRM.
What if I already have a receptionist?
You can use it as a supplement to your existing receptionist. When the receptionist is not available, the AI voice agent can answer common questions, book appointments, and log calls/leads. Enabling and disabling the AI voice agent is easy and can be done in seconds based on your business needs.
Can it answer customer questions during the call?
Yes. We train it on your services, policies, coverage area, and FAQs so it can handle the full conversation - not just "take a message."
What if the agent isn't confident about something?
It's designed to know its limits. It escalates to your team with full context instead of guessing.
Can it book directly with the right person?
Yes. We configure routing rules so the agent schedules with the right calendar/person based on the request type (service vs. maintenance vs. estimate, etc.).
How fast can I get started?
Setup is typically 48 hours, and fully live in about 30 days depending on complexity. You can start with a 7-day pilot free of charges.
What's included in the 7-day risk-free pilot?
The agent handles an agreed slice of your inbound calls (for example: after-hours or overflow). If you're not satisfied within 7 days, you can opt out without paying - no contracts, no commitments.
How do you prevent double-booking or scheduling conflicts?
We use calendar checks and collision rules to avoid conflicts and book only valid slots.
Is my data secure?
Yes. You maintain ownership and control. We implement audit logs and privacy-first practices.
What guarantees do you offer?
• 7-Day Risk-Free Pilot: Opt out within 7 days if you're not satisfied.
• Response Time Guarantee: Pickup within 2 minutes, 24/7 (typically seconds).
• Integration Support: We handle setup and calendar integration; you don't lift a finger.
