Missed calls on a heating van in January
Quick summary
- You are in a basement with the burner open. The other person is bleeding a radiator. That is when the published number rings.
- A tenant with no heat hangs up. So does the person staring at a red light, asking which button to press.
- The voicemail holds annual services. The lockout and the first frost leave nothing.
- The first split is oil, gas or pellet. A lockout is a note. A service is a morning that is actually free.
- After the first frost, or on a Monday after a weekend of cold rooms, several people ring at once.
- It never tells them to press reset, bypass a switch, or keep trying a lockout.
TL;DR
You are in a basement with the burner open. Across town the other person is on a landing with a radiator key. The phone rings. The tenant whose flat went cold in the night will not leave a message. The person in the plant room with a red light will not leave one either. They hang up and dial the next van. An assistant answers, asks oil, gas or pellet, takes whether there is heat, a light or a smell, writes the address down, and books a morning only if that morning is free. It does not talk anyone through a reset. After the first frost, or on a Monday, it takes several conversations at once.
Key takeaways
- Pull unanswered calls by hour from the provider, and mark frost mornings and Mondays in January on their own.
- Do not judge the loss by the voicemail. A lockout and a first no-heat leave nothing.
- Forward after a short ring so a free pair of hands still takes the call. Shorten that after the first frost.
- Tag lockout and service separately. A red light is not an annual clean.
- Give it the sentence: the technician looks at the boiler. It does not tell them to override a lockout.
- Re-count unanswered calls after four weeks. If January mornings have not dropped, the ring-time is wrong, not the greeting.
In the basement, and the phone still ringing
The burner is open. Yesterday’s nozzle is still on the cloth. Across town the other person has a radiator key on a top-floor landing. The published number rings. You cannot let go of the gun. The colleague cannot leave the landing mid-bleed. There is no third pair of hands.
You let it go. A few seconds later the number is gone.
This happens in the hours the van says it is on the road. The listing says open. The card on the tank says open. The person calling already has another van on the same card. They wanted an answer. They hang up and dial that number.
You know which boilers you opened this morning and which radiators are on the pad. The number you usually do not have is how many people tried to reach you and could not. That number is in the provider’s log. Pull it. Mark the frost mornings. Mark the Mondays in January.
Those mornings are the ones you believe you are working and busy. One of you inside a jacket. The other on a landing. The number on the van is ringing. Nobody is free for a lockout, and nobody is free for a first service that should have been booked in October.
Who hangs up
Three things happen when nobody picks up. They do not cost the same.
Someone whose boiler you already service will often leave a message. They want the annual clean before the inspection. They want a date for the chimney sweep. They will still be there this afternoon. These are the voices you hear when you open the voicemail, so these are the voices that shape what you think the problem is.
Someone standing in a plant room with a red light will not leave a message. Someone whose flat went cold at six will not. A foreign owner who asked whether you work in English and heard a busy tone will not. They hang up. The provider’s log has a short ring. Your voicemail has nothing.
Someone who already tried twice after last year’s first frost, or whose neighbour told them you never pick up on a Monday, never rings again. That one is not in the log either.
The people who hang up are usually calling about a lockout or a first no-heat. Those are two different jobs. What they needed first was an answer. The reset, if any, is what you do when you are in front of the boiler.
Why the voicemail hides the new plant
In January you get two jobs on the same phone. When you open the voicemail you hear the wrong one.
The existing client has a boiler on your list and a reason to persist. They leave a message, or they wait for the annual letter. The person with the lockout, and the person who just moved into a cold flat, have neither. They cannot quote a contract number they have never been given. They cannot wait, because the house is cold now. The children are in jumpers. The shop cannot open the door.
So you finish the burner, you open the voicemail, and you hear a service and a chimney date. You do not hear the oil plant on Papanastasiou. You do not hear the gas wall unit that needed a look this afternoon. Those people never spoke into the box.
The calls also arrive together. The first frost is not one missed call an hour. It is five in twenty minutes, and both of you are already on a job. A second person on the van takes the first two. The third still hears a busy tone.
A caller rings about a lockout and also wants the annual service booked. That is a note and a morning. If the note says only “Mr Kostas, heating”, both wait, and the service half is the one that will go to another van.
Smell of gas, carbon monoxide alarm, water on the boiler floor: those cannot wait in the evening list. They also cannot be finished by an assistant reading a reset to keep the caller on the line. Take the request. Flag a phone. Say the technician looks at the boiler.
Frost, Monday, and a manager afternoon
These are not the same overflow. If you teach the assistant one generic “busy morning” label, it will treat a person in a plant room like a chimney booking.
Frost is lockouts and no heat. By eight, people have started ringing. You are already in the first basement. The pad is already a list of addresses. A lockout in that hour is a note. A service call in the same hour is a morning or a callback. If the assistant parks the person who wants the annual clean behind the tenth cold flat, that person rings the next van.
Monday is a smaller version of the same hour. People report the weekend of cold radiators. People who ignored the October letter ring about a service they now want today. Tag them separately. The lockout is the fuel, the light, the address. The service is a morning in the book. Mix them and you sit down at eleven with someone who only needed a note, while the person who needed the clean has already booked the other van.
A manager afternoon is three flats in the same block, all cold, all expecting you in twenty minutes, all describing the same plant from the stairwell. Shorten the ring-time before forwarding on those afternoons. The third caller should not hear a busy tone.
August needs its own dates. Some of you close for two weeks. Some of you leave one person on the books. The published number still rings. Set the closure dates. Do not let the assistant book a service into a week when the van is dark.
Lockout is a note. A service is a morning.
The first question on the overflow is not when they are free. The first question is oil, gas or pellet, then whether this is a lockout or a booking.
Lockout or no heat. Something already happened. A red light, a bang in the basement, a flat that went cold, a smell. The assistant asks for the fuel, then the light, then smell or no smell, then the address, then a name and a number. It writes that down. It does not open a reset. If they want a look booked, it checks the book and offers a morning that is free. If they smell gas, or a carbon monoxide alarm is sounding, it stops the intake and puts the caller through to a phone you actually hold.
Service. They want the annual clean, a chimney date, a summer check, a quote for a new boiler. The assistant asks which of those they mean, then looks at the book. It does not invent a boiler price from a photo of the plate. It does not pick oil or gas for them. If you have closed new plant this month, it says so on the first call, from the line you typed in.
A ten-minute thermostat look is not a plant-room morning. An annual clean is not a lockout. Mark them as different visits, or the overflow will fill Thursday with people who only needed a note, and the person who needed three hours on a communal plant will be given twenty minutes at the door.
People remember that it is cold. They do not remember the fuel. Ask the fuel first. If they offer the brand on the jacket, take that too. One fuel is enough to send the right van. None is still a note, not a guess from a picture.
Calls that cannot wait until you close the jacket
Four calls on this phone do not belong in a digest you read after the burner is back together.
Smell of gas, or a carbon monoxide alarm. That is a transfer. You give the assistant a short list. It collects a name and a number while it is connecting. It does not tell them which window to open. It does not tell them to press reset.
They are still in the plant room, with a red light, asking which button. The assistant takes the fuel, the light, the address. It refuses the sequence. Come-now or this-afternoon is yours, after you know where the van is.
Water on the boiler floor. Flag it. Do not invent a leak cause from a description. Do not tell them to mop and reset.
No heat in January with children in the flat, or a shop that cannot open. That is a same-day phone, not an evening list. The assistant takes the fuel and a number. It does not say you will be there in twenty minutes.
Everything else can wait for the transcript: a first look at a new boiler, a summer check, a chimney date for next week, a missing filter from last Wednesday.
What the assistant must do on the overflow
Answer. Nobody picked up. That is the loss. A person who would have hung up now has someone on the line.
Every answered call should already know the split: oil, gas or pellet; lockout or service; ordinary note or same-day flag. A loss that used to be invisible becomes a list you can work when you close the jacket.
It does not read a reset. “Which button?”, “hold it for three seconds?”, “my neighbour said to jumper the switch” are written down and refused. The technician looks at the boiler.
Fuel first. If every name lands in one column you have a heap, not a callback list. A caller who is both — a lockout and an annual clean — still gets two notes. Those are two conversations for you, even if they arrived as one call.
It books a morning you can actually keep, or it writes the request down. It checks the book before it offers a time. It never offers a plant-room morning in an hour you have closed for someone else’s burner. It confirms by SMS, in the language of the call — 70+ languages.
It does not invent an arrival, quote a boiler from a plate, or pick a fuel. If a caller asks for a round figure from a WhatsApp photo, the assistant records the question and says the technician will call back.
Gas, carbon monoxide, water on the floor, lockout-with-no-heat remain a flag to a phone. The assistant collects a name and a number. It does not fill the waiting with a reset sentence.
What you set first
- Pull the call log first. Unanswered calls per hour and per day, a month back, with frost mornings and January Mondays marked. If you skip this you will never know whether anything improved.
- Forward on no-answer, not always. A short ring in a quiet week. Shorter after the first frost, so overflow is caught while you stay in the basement. A call you pick up never leaves the van. See pricing.
- What you actually run, and whether you take communal plant this month. A van that is oil-only should say so on the first call, not after a booked morning at a gas wall unit.
- Require the fuel question on every new call, then lockout or service, then the address.
- Tag the categories you care about — lockout, no heat, noise, smell, annual service, new boiler, same-day flag — so the weekly summary is a decision aid rather than a pile.
- Route gas, carbon monoxide, water on the floor and lockout-with-no-heat to a phone, not into an email digest that gets read after the jacket is closed.
- Enter the two kinds of visit. A plant-room morning that needs you at the boiler, and a short radiator or thermostat look.
- Re-pull the call log after four weeks and compare unanswered calls, not “calls the assistant handled”.
A quiet April Tuesday is not the test
A Tuesday in April is useful for checking that the greeting is right and that the assistant asks oil, gas or pellet. It will not tell you whether you are still losing the lockout at seven in January.
The first frost, and the Monday after a cold weekend, are where the new-plant leak hides, because that is when you believe you are working. Set the forwarding rule so both windows are covered. Then look at them as two columns. If quiet weeks go to zero unanswered and frost mornings do not, you have a ring-time problem on the burst, not a greeting problem.
After hours still exist. People ring from a plant room at 21:40. Managers send tenants out after six. Measure those calls as their own column.
Do not put a reset diagram in the notes. It will read the diagram out.
How to read the provider’s log
Do this once, on paper, before you change the forwarding rule. Pull one January Monday and read it against the pad. Count three things.
Count the unanswered rings in the morning, when one of you is in a basement and the other is on a landing.
Count the messages that came from people you already know. Those are the annual services and the chimney dates. They will still be there this afternoon. They are the only missed calls you can name without the log, because they left a voice.
Count the numbers that appear once, for a few seconds, and never again. You cannot tell from the log what they wanted, because nobody answered. A lockout, a first no-heat, a foreign owner asking whether you work in English: all of those look the same when they hang up. The next Monday, if the assistant took the overflow, those lines have a transcript and either a lockout note or a service morning.
The log will also show a number that rang four times in six minutes. That is usually someone still in the plant room, or a manager with three cold flats, or a shop that cannot open. Send it to a phone.
After you have those three counts, look at the forwarding delay on a frost morning. A short ring is right when you can pick up. It is too long after the first frost, when the fourth caller is already gone.
What changes after it answers
A person who would have hung up now has a lockout note with a fuel and an address, or a service on a morning that is free, or your phone ringing because someone can smell gas.
It does not decide which button to press. It does not decide that the tank is empty. It does not invent a boiler price to be helpful. Fuel and lockout are labels on the note, so the right van sees them. They are not a reset.
It does not replace the callback. An existing client who asked whether the flue is due still needs you. The difference is that you now call back a number written down at 11:42, instead of discovering at 20:00 that someone rang and said “heating”.
Finish a no-heat request first. Treat a service as a morning in the book. A thermostat look is twenty minutes on a landing. A communal plant is you, the key, and three hours.
The value of a no-heat visit is yours to put in. The worked example above is arithmetic on stated assumptions. A van that lives on oil and a van that lives on heat pumps are not the same business. Put your own figure in.
Whoever takes the lockout often takes the contract. That is why a missed January call is not only a missed note.

What January's voicemail hid on a two-person heating van
Worked from these assumptions — change any of them and the answer changes:
- Two people, a January Monday after the first frost, roughly 16 inbound calls before early afternoon.
- About a third arrive while one of you is in a basement and the other is on a landing.
- Someone reaches 5 of those overflow calls. The other 6 ring out.
- Of the 6, 2 leave a message about an annual service. 4 leave nothing.
- A same-day no-heat visit that becomes work is worth about €120 — put your own call-out plus first hour in, this is the number to change first.
- This example treats 3 of those 4 silent calls as no-heat or lockout that then went to the next van.
- The voicemail after lunch shows 2 people. That is the number the van believes.
- The provider's log shows 6 unanswered. The other 4 never left a word.
- 3 of those 4 were no-heat. 3 × €120 = €360 of work, that Monday.
- Frost mornings, say 16 of them across January and February — 16 × €360. Put your own weeks in if you close in August.
About €5,760 from those two months, from the same Monday window repeating — and only if you accept the conversion above. Change it.

Frequently asked questions
How do I find out how many calls we are actually missing?
Ask the telephony provider for unanswered calls by hour and by day, before you buy anything, including this. Mark frost mornings and Mondays in January on that list. Then open the voicemail for the same days. The numbers that rang for a few seconds and left nothing are the lockout in the basement and the tenant who was cold at seven.
Would another person on the van not solve this?
The calls do not arrive evenly. Two people take the first two basements. The third still hears a busy tone if one of you is inside a jacket and the other is on a landing. Adding a person changes how many can pick up by one. It does not change the first frost, when five lockouts ring in the same twenty minutes.
Does voicemail not catch them?
It catches the boilers you already service. Someone whose plant you cleaned last October, calling about the annual letter, will often leave a message. Someone staring at a red light, and someone whose flat went cold in the night, will not. They hang up and dial the next van. So the voicemail under-reports the calls that open a new plant room.
What happens to the calls we do answer?
They stay with you. The forwarding rule only sends a call onward when it has rung unanswered for the number of seconds you choose. A call you pick up is never forwarded. See [pricing](/en/#pricing) for how that is treated.
Can it tell them which button to press?
It must not. It takes the fuel, whether there is a light, whether there is a smell, the address, and a number, and puts the note in front of you. A reset is work in front of the boiler. The assistant does not answer a lockout question to sound helpful.
How quickly can we tell whether it worked?
Four weeks, with the same call log you pulled at the start, split by frost mornings, January Mondays, and the rest. The measure is unanswered calls, not calls the assistant handled. A figure that only counts what the assistant did cannot tell you whether anyone is still ringing out while you are in a basement.
