The AI answering service for HVAC companies that books the call while you're on a roof.
Callsy answers every call in one ring, captures the address and the fault, books the visit into your diary, and texts a confirmation. On a job, after hours, and on weekends. So the next no-heat or no-cool call becomes a booked job, not a missed call.
What your hvac answering service does
Answers every call, on the job
You can't answer on a rooftop or mid-install. Callsy picks up on the first ring, so the no-heat call you'd have missed becomes a booked job.
Captures the fault and address
It gets the address, the system, and the symptom, and asks your triage questions so you know if it's a dead furnace or a routine service before you drive out.
Books into your diary
It offers real slots, books the visit on the call, and texts a confirmation with your details. No callback tag, no lost lead.
Handles emergency triage
It flags true emergencies (no heat in winter, no cool in a heatwave, gas smell) and warm-transfers or escalates them to you, while booking routine work for the next slot.
Covers peak-season overflow
The first cold snap and the first heatwave bury the phones. That's exactly when Callsy answers and books every call instead of letting them ring out.
Speaks like your firm
A friendly, local-sounding greeting trained on your services and areas. Callers reach a helpful person, not a generic message service.
The basics
What is an HVAC answering service?
An HVAC answering service answers your calls when you're on a job, driving, or asleep, so a customer with no heat or no cooling always reaches someone. An AI answering service like Callsy does more than take a message: it captures the address and the fault, triages the urgency, and books the visit into your diary on the call, 24/7.
Around a third of calls to small trades go unanswered, and most callers won't leave a voicemail, they just call the next company. A human answering service charges per minute to take a message you still have to action. Callsy is a flat monthly fee, works around the clock, and turns the call into a booked job, so it usually pays for itself with a single recovered emergency call in peak season.
Why HVAC firms lose jobs on the phone
You can't answer on a job
On a roof, in an attic, mid-install. The call rings out, the customer calls the next number, and the job is gone before you've seen the missed call.
Breakdowns spike with the weather
The first freeze and the first heatwave send calls through the roof. Whoever answers gets the emergency-rate job. Voicemail gets nothing.
Callers don't leave voicemails
Most people who reach a voicemail hang up and dial the next result. A message service you check later has already lost the job.
A message isn't a booking
Even when a service takes a message, you still have to call back and book. Callsy books the visit into your diary on the first call.
HVAC answering service FAQ
What is an HVAC answering service?+
It's a service that answers your calls when you can't, so customers with no heat or no cooling always reach someone. Callsy is an AI answering service: it answers 24/7, captures the address and fault, triages urgency, and books the visit into your diary on the call, instead of just taking a message you have to action later.
Can it book jobs into my calendar or field-service software?+
Yes. Callsy offers real slots from your calendar and books on the call, then texts a confirmation. It integrates with job-management tools like ServiceTitan, Housecall Pro, Jobber, Commusoft, and ServiceM8, so the job lands where you already work.
Does it handle emergency calls?+
Yes. You set the triage rules. Callsy flags true emergencies (no heat in winter, no cool in a heatwave, gas smell) and warm-transfers or escalates them to you straight away, while booking routine work into your next available slot.
How much does it cost?+
Human answering services charge per minute or per call, so a busy season gets expensive. Callsy is a flat monthly fee for 24/7 cover, so a single recovered emergency job usually pays for the whole month. There's a free trial, and if it doesn't pay for itself in 30 days you don't pay.
