AI Voice Agent for Heating & HVAC:
Every Breakdown Call Answered

Our AI voice agent works as an AI receptionist for HVAC services and heating engineers. It answers every customer call on the first ring, books breakdowns, boiler services and landlord gas safety certificates, and takes quote requests, even when the first cold snap hits. It never diagnoses a fault. We build it around your firm and manage it every month.

What is an AI receptionist for HVAC services and heating engineers?

An AI receptionist for HVAC services is software that answers and makes phone calls for your heating firm in natural, spoken conversation. Some firms call it an HVAC AI receptionist; we call it an AI voice agent, because on Growth and Scale it does more than answer the phone. It works out whether the caller has a breakdown, needs a service or a gas safety certificate, or wants a quote, answers from prices and information you have approved, books visits into your diary and passes anything technical to your team, with a summary of the call.

Callers don't press buttons or leave voicemails. They say what they need, and the agent responds the way a well-trained office manager would. The difference with OMH is that we set it up and run it for you: we write the script around your real calls, connect your diary and job software, and keep improving it. See our AI receptionist plan if you only need the phone answered.

How a call goes

Watch the phone. Each step lights up as the call reaches it.

  1. It listens.It hears whether it's a breakdown, a service, a landlord certificate or a quote as the customer speaks.
  2. It works out the answer.It matches the request to your diary, service areas and booking rules.
  3. It replies and acts.It answers in a natural voice, books the visit or puts the call through.
  4. It reports back.Your team gets a summary of every call. Callers can interrupt or change their mind at any point.

Megan, AI assistant

CallerOur boiler's stopped and we've got no heating or hot water. Can someone come out today?
MeganSorry to hear that. I've noted the fault code. An engineer can come today between 12 and 2. Shall I book it?

Breakdown booked: today 12:00 to 14:00

Summary sent to the office: no heat or hot water, make, model and fault code noted

A day at your firm

Calls don't arrive evenly.
Neither do the misses.

An illustrative winter weekday at a heating firm with one office and four engineers. Most missed calls land first thing, over lunch and after the office closes, which is exactly when nobody is free to pick up.

Calls by hour, one weekday

218 calls, 90 missed (41%). Hover or tap a bar for the hour.

Illustrative figures, not data from a real business. Your phone provider's call log shows your own pattern.

  1. 07:00No heat at breakfast

    Customers find the boiler has stopped when they get up. The office isn't open yet and the phone rings out.

  2. 12:30Lunch cover

    One person in the office, or nobody. The phone rings out while they chase a parts order.

  3. 18:00After the office closes

    Customers ring after work. Voicemail picks up and many hang up and try the next firm.

First-ring answering, 24/7

The agent

Every customer call answered straight away, from the first cold snap to evenings, weekends and bank holidays. No engaged tone and no hold music.

OMH, for you

We divert your office line, set your hours and agree what it picks up and when: overflow, out of hours or every call. Nothing goes live without your sign-off.

Your engineers stay in charge

You decide the rules before it answers a single call. Anyone who smells gas is told to call the National Gas Emergency Service on 0800 111 999. Out of hours, urgent breakdowns go to your on-call engineer or the top of the morning summary, never to a voicemail.

It handles

  • Bookings, moves and cancellations
  • Make, model and fault code details
  • Opening hours and the areas you cover
  • Call-out fees and service plan details you approve

It hands to your team

  • Fault questions or anything technical
  • Complaints and sensitive calls
  • Anyone who asks for a person
  • Questions it has no approved answer for

It never

  • Diagnoses a fault or suggests a fix
  • Gives gas safety advice beyond 0800 111 999
  • Pretends to be a person
  • Calls customers who have not agreed to it

Works alongside your job software

Bookings and notes go where your team already looks. We check your setup on the first call and tell you plainly what connects directly and what needs a workaround.

Use cases

Heating and HVAC use cases by type of call

A heating firm's office gets the same eight kinds of call, day in, day out, and any AI receptionist for HVAC companies has to handle all of them. We script your agent around each one. Pick a call to see how the agent handles it.

No heating or hot water01 / 08

Breakdowns: no heating or hot water put first

A breakdown is the call you can least afford to miss. The agent takes the make, model and any fault code on the display, asks whether anyone in the home is vulnerable and books by your priority rules. It never diagnoses the fault.

  • Takes the make, model and fault code shown
  • Books into the slots you hold back for breakdowns
  • Flags elderly customers and young children by your rules

No fault diagnosis given.

Not sure how your calls would fit?

Tell us who rings your firm and why. We'll map your calls and show you what the agent would handle and what it would pass to the office.

Showing all 20 questions

Will customers know they are talking to an AI?

Yes. Every agent says it is an AI assistant at the start of the call. Customers deserve to know, and anyone who would rather speak to a person can ask.

Does it diagnose faults or give gas safety advice?

No. The agent never diagnoses a fault, suggests a fix or tells anyone an appliance is safe to use. It takes the make, model and any fault code on the display, books an engineer by your rules and passes anything technical to your team.

What happens if a caller says they can smell gas?

The agent tells them to call the National Gas Emergency Service on 0800 111 999 straight away. It gives no other gas safety advice. The call is flagged for your team at once and sits at the top of the summary.

What happens if a caller thinks there is carbon monoxide?

The same as a smell of gas. The agent tells them to call the National Gas Emergency Service on 0800 111 999 straight away, and to call 999 if anyone feels unwell. It gives no other safety advice. The call is flagged for your team at once and sits at the top of the summary.

How does it handle breakdowns with no heating or hot water?

It follows the priority rules you set. It takes the make, model and fault code, asks whether anyone in the home is elderly, unwell or very young if you want it to, and books into the slots you hold back for breakdowns. Every breakdown is flagged in the summary.

Can it book landlord gas safety certificates?

Yes. Landlords and letting agents can book several properties on one call. The agent takes each address, the tenant's contact details for access and the date the current certificate runs out, then books CP12 visits into the slots you set.

Does it work for service plan and warranty customers?

Yes. It notes plan and warranty numbers, answers from the plan details you approve and books plan customers into the slots you set for them. Questions about what a manufacturer's warranty covers go to your team.

Can it book quotes for new boilers, heat pumps and air conditioning?

Yes. It takes the property type, the current system and what the customer wants, then books a survey visit with the right engineer. It never quotes a price you haven't approved.

How does it cope with the winter rush?

It answers every line at once, so nobody hears an engaged tone when the first cold snap hits. It books by your priority rules, breakdowns first, and gives you a list of every caller and what was booked.

Can the agent put a caller through to the office or an engineer?

Yes, on the Growth and Scale plans. You set the rules: urgent breakdowns, complaints, technical questions and anyone who asks for a person can be put through to the right phone, including your on-call engineer out of hours. On the Starter plan, the agent takes a detailed message and sends it to your team.

What happens when the agent doesn't know the answer?

It says so. The agent answers only from information you have approved, so when a question falls outside that, it offers to take a message or transfer the call. We review those moments and add the answers worth adding.

Does it work with our job management software?

It works with most diaries and job management systems. We check yours on the first call and tell you plainly what connects directly and what needs a workaround.

Can we keep our phone number, or get a local one?

You can keep your number and divert calls to the agent, either all of them or only the ones the office misses. If you want a local number for a new area you cover, we can set one up.

How long does setup take?

Starter goes live in 3 working days, Growth in 5 to 7 and Scale in 12 to 15. The clock starts once we have your price list, service areas, booking rules and diary access. If your firm is more complex than usual, we give you a realistic timeline after the discovery call, before you commit to anything.

Is customer data kept safe?

You remain the data controller and OMH acts as your processor under a written data processing agreement, in line with UK GDPR. We agree what is stored, where and for how long before go-live.

Are calls recorded?

Only if you want them to be. Customers are told at the start of the call, and recordings are deleted on the schedule you set.

Can it call customers when a service or certificate is due?

Only customers who have agreed to reminders. We follow the UK PECR rules and act on opt-outs straight away; opt-outs are removed the same day. We don't run cold calling campaigns.

Will it replace our office staff?

No. It takes the overflow and the routine calls, so your team can look after the jobs in front of them. You choose when it answers: only when the lines are busy, only out of hours, or first on every call. Anything technical, sensitive or complicated still goes to your team.

How much does an AI receptionist for HVAC services cost?

Our AI receptionist for HVAC services and heating engineers (the Starter plan) is £249 a month plus VAT with 300 minutes included, and a one-off setup fee from £795. Growth is £449 a month and Scale, for firms with several depots or teams, is £849 a month. Extra minutes cost 60p each on every plan.

Is there a minimum contract?

Plans are billed monthly with 30 days' notice. We set out the terms in writing before you start, including what's included each month and what counts as extra. Every invoice shows your included minutes and any overage.
