What does an HVAC answering service do?

It answers the calls your team cannot get to: nights, weekends, and the hours when every tech is on a job. With KaiCalls, your cell rings first. If nobody picks up, Kai answers in your company name, asks your questions about the system and the problem, and texts you a summary when the call ends.

Will Kai send every 2am call to my on-call tech?

No. You decide what counts as urgent, such as no heat below a set temperature, a gas smell, or water near electrical. Those can be transferred to your on-call number. Everything else is written up for the morning.

Can Kai book tune-ups and estimates?

Yes. With Google Calendar connected, Kai books into the hours you allow. Without a calendar, he takes the caller details and preferred window so your office can confirm.

Does it work with Housecall Pro or Jobber?

Yes. Once connected, Kai can send the caller and job details to Housecall Pro, Jobber, Workiz and other supported tools, so the call becomes a job record instead of a voicemail.

Do I have to forward my business number?

No. Every plan includes a business phone number you can use as your main line. If customers already call an old number, forward only the calls you do not pick up. Forwarding all calls would stop your own phone from ringing.

HVAC Answering Service for Nights & Weekends

HVAC answering service

The calls an HVAC company gets when nobody can pick up

Most HVAC calls that go to voicemail are not routine. They come in at night, on weekends and on the hottest and coldest days of the year, when the caller will dial the next company on the list. These are the calls Kai is set up to sort.

No heat on a cold night

Kai asks whether the furnace runs at all, what the thermostat shows, whether the breaker was checked, and whether anyone at home is at risk from the cold. If it meets your urgent rule, it goes to your on-call tech.

No AC in a heat wave

Kai gets the address, whether the outdoor unit is running, if the unit is iced over, and how hot it is inside. You decide which of these wake someone up and which get the first slot in the morning.

Gas smell or a CO alarm

You can set Kai to tell the caller to leave the house and call 911 or the gas company first, then flag the call to you with the address and callback number.

Water leaking from the indoor unit

Kai asks where the water is, how much, and whether it is near anything electrical, so the tech knows if it is a clogged drain line tonight or a visit tomorrow.

Tune-ups and maintenance

Routine calls get booked on your Google Calendar inside the hours you allow, or Kai takes the preferred window so the office can confirm.

Replacement and new system quotes

Kai asks the age of the system, home size, fuel type and what is wrong with the current setup, then books or requests an estimate visit.

What happens to a call at 9pm

1
Your cell rings first
Calls ring your phone, or up to five phones in order. Pick up and it is a normal call.
2
Kai answers the ones you miss
If nobody picks up, or it is after hours, Kai answers in the name of your business. Callers reach an HVAC company that answers, not a voicemail beep.
3
He asks your questions
Name, callback number, address, what is wrong and how urgent it is. You decide what counts as urgent and who gets the call.
4
Urgent calls reach you
When a call meets your urgent rules, Kai can transfer it to your on-call number. Everything else waits for the morning with notes attached.
5
You get a text
Seconds after the call ends, you get a text summary: who called, what they need, and how to reach them. The recording and transcript are in the app.

What it costs

Plans start at $10/mo on Kai Backup (~20 Kai-answered calls/mo). Every plan, flat monthly: Kai Backup $10/mo, Kai Line $79/mo and Kai Office $349/mo.

There are no per-minute overage charges. Your plan includes an expected monthly call allowance. If your call volume stays higher, we recommend the next plan and notify you before anything changes. You can choose to keep your current plan, and we move you back down if volume drops.

Every plan includes a business phone number, so you can keep it as your main line or forward only the calls you miss from the number you have now.

FIELD GUIDE

How Kai Handles Calls for HVAC

Kai is trained around the actual calls that reach hvac teams: urgency, qualification, routing, booking, and follow-up.

Peak Routing

Kai Handles Peak Season Overflow Without a Phone Queue

01

HVAC call volume can jump during summer and winter peaks. Kai gives callers a consistent intake path and sorts the work by urgency.

Kai asks whether the caller has no heat, no AC, a gas smell, a frozen unit, water near the system, or a routine maintenance need.

Emergency calls get routed to the on-call tech. Tune-ups, filter questions, warranty calls, and replacement estimates get scheduled into normal capacity.

Qualification

Kai Captures System Details Before the Tech Calls Back

02

HVAC dispatch works better when the first summary includes the unit, symptoms, and property context.

Kai collects equipment type, brand or model when known, system age, thermostat behavior, breaker status, airflow symptoms, and warranty status.

For replacement leads, Kai asks about home size, current fuel source, comfort problems, and preferred estimate window.

Repair intake

No heat, no AC, noise, leak, short cycling, and airflow issues get clean symptom notes.

Install intake

New systems, heat pumps, ductwork, and efficiency upgrades get routed as sales opportunities.

Handoff

Jobs Move Into the Tools Your Dispatcher Already Uses

03

Kai does not require a new workflow just to answer the phone. It sends structured call data to the system your team already checks.

Google Calendar, GoHighLevel, Zapier, webhook, SMS, email, and supported CRM handoffs can include customer details, urgency, job type, and requested appointment window.

The result is a usable dispatch note, not a raw transcript your office has to decode during a heat wave.

Who Kai works for

Fix the calls that make customers call someone else

Kai is built for the messy, high-intent moments where speed, context, and calm follow-through decide who gets the job.

Peak Season Call Overflow

What breaks

When it's 105 degrees in July or the furnace dies in January, call volume can surge. Your team can be on jobs while new callers still need a useful response.

What Kai does

Kai collects service details during peak-season surges, triages emergencies, and routes routine appointment requests into your follow-up workflow

After-Hours Emergencies

What breaks

AC failures at midnight in summer and furnace breakdowns on freezing winter nights can't wait until morning. Customers need help now, not a voicemail.

What Kai does

24/7 emergency call handling captures system details, assesses urgency, and alerts your on-call path for true emergencies while collecting non-urgent scheduling details

Techs on Jobs Can't Answer Phones

What breaks

Your best technicians are on-site handling installs and repairs. They can't stop mid-job to answer the phone, and office staff gets overwhelmed.

Kai becomes an always-available intake path while your team focuses on the work that generates revenue
