AI Answering Service for HVAC Companies

Boiler breakdowns don't wait for business hours. Neither should your phone answering. OnCallClerk picks up every HVAC call, day and night.

Sound Familiar?

These are the phone challenges hvac businesses face every day.

Seasonal Call Floods

First cold snap of winter or first heatwave of summer, your phone explodes. You physically can't answer every call, and each missed one is a lost job.

On-Site All Day

Installing a boiler or servicing an AC unit takes hours. You're crawling through lofts and working in plant rooms. The phone isn't getting answered.

Emergency Calls at Night

No heating in January. AC failure during a heatwave. These callers are desperate and willing to pay premium rates, but only if someone picks up.

Annual Service Reminders

Customers calling to book their annual boiler service or AC check clutter your phone line, taking time away from more complex enquiries.

How OnCallClerk Solves This

AI phone answering built specifically for hvac businesses.

24/7 Availability

Every call answered instantly, including overnight emergencies, weekend breakdowns, and the seasonal rush periods that overwhelm your lines.

Emergency Triage

The AI identifies genuine emergencies (no heating with vulnerable residents, gas smells, CO alarm activation) and routes them to you immediately.

Handles the Seasonal Spike

When 20 people call in one morning because their boilers have packed in, the AI handles them all simultaneously. No engaged tones, no voicemail.

Service Booking

Annual service calls, routine maintenance, and system checks can be booked directly through the AI without tying up your time.

Accurate Job Capture

The AI collects the make and model of the system, the fault description, the property type, and the customer's availability. You get a complete brief.

Frequently Asked Questions

Can the AI handle the seasonal call spike?

Yes. The AI handles unlimited concurrent calls. When 15 people call at once on the first cold day, all 15 get answered immediately.

How does emergency routing work for HVAC?

You define your emergencies: no heating with elderly or children, gas smell, CO alarm, complete system failure. The AI spots these and transfers or alerts you right away.

Can it book boiler service appointments?

Yes. The AI checks your availability and books routine service appointments, or captures preferred dates for your team to confirm.

Does it know about different boiler brands and systems?

It knows whatever you tell it. Add your specialisms, the brands you work on, and common fault descriptions during setup.

How much does it cost?

From $30/month. The same price whether you get 10 calls or 200. No per-call charges that spike during your busiest season.
