HVAC companies · WhatsApp marketing

Take the photograph of the error code and book the visit in one chat.

WhatsApp is how an HVAC customer reports a fault, because photographing a blinking indoor unit is easier than describing it. GullySales sets up the business account, writes the replies that book a slot, and builds the service reminder that goes out before the season.

What WhatsApp marketing means

WhatsApp marketing is sending updates, offers and reminders to customers on the app most Indian buyers already check daily. GullySales sets up business WhatsApp, writes the message templates and keeps the list consented and current.

Sales and marketing for HVAC companies, the overview.

For HVAC companies

Where it usually goes wrong, and what we would do.

  • “The customer sends a picture of the error code”

    A blinking light on an indoor unit is easier to photograph than to explain. Your technician can often name the part before anyone drives anywhere.

  • “One reminder before summer beats a year of posting”

    A single message to your whole service list, sent before the first hot week, does more than any campaign. Send four and people leave the list.

  • “A commercial customer wants a group, not a broadcast”

    A facilities head wants the complaint, the technician's arrival and the closure in one thread with your supervisor in it. That is a service channel rather than a marketing one.

What we do

What we deliver for HVAC companies.

Every deliverable, what it covers for you, and the result it is there to produce. Nothing here is an extra.

  1. WhatsApp Business set up with services, areas and response detail

    Installation, repair and AMC listed with the localities you cover and how a visit is booked, on a number the company owns.

    Result: A caller knows what you do and where before anyone types.

  2. An away message that handles the out-of-hours breakdown

    An automatic reply asking for the address, the unit type and a photograph of the fault, with the hour the office opens.

    Result: The first call of the morning starts with the details already in hand.

  3. Ready replies that book a slot rather than promise a call

    Written messages offering a visit window, confirming the visit charge and capturing the address, used by whoever is holding the phone.

    Result: An enquiry becomes a booked job in the same conversation.

  4. A pre-summer service reminder to the consented list

    One message before the season to past customers offering a check and a slot, with AMC customers kept on a separate list.

    Result: Bookings arrive before the rush instead of during it.

  5. A site thread for each commercial account

    A group per building holding the facilities contact, your supervisor and the technician, used for complaints and closures.

    Result: A facilities head stops chasing your office for an update.

  6. Consent and opt-out recorded against the customer

    A recorded yes at the point of service and a simple way to stop, kept on the customer record rather than in someone's head.

    Result: The list stays clean and your number stays unblocked.

  7. Enquiries, reply time and jobs booked against the baseline

    How many enquiries arrived in the chat, how quickly they were answered and how many became visits, measured against the baseline recorded before work started.

    Result: You can see what the channel does in a peak week.

How the result is measured

  • Messages delivered
  • Reply rate
  • Enquiries from WhatsApp

Recorded as a baseline before work starts, so every later report has an honest comparison.

What must be in place first

Settle these before reminders go to the service list.

Consent on the service report
Add a line to the service report: may we message you the next service reminder on this number. Record it against the site and the unit, since the person who signs may not be the owner.
A unit register behind the reminder
Hold each customer's units with brand, capacity such as 1.5 ton, install date and AMC end date. A reminder for a unit that was removed or replaced damages trust.
What an error-code photo can answer
Give staff a short list of the models you service and the codes you will ask about. Say plainly what remote guidance cannot do, such as gas work, which needs a technician.
Reminders you start yourself
A service reminder sent when the customer has not written recently may need an approved template. Check WhatsApp's current business policy and pricing before planning a season message.
Commercial site threads with agreed rules
For a mall or hospital contract, agree who is in the thread, what counts as a breakdown report, and who logs it in the ticket system.

Who it is for

This is written for these HVAC companies.

  • Residential split AC installers
  • Commercial VRF and VRV contractors
  • Chiller plant and industrial cooling specialists
  • Cold storage and refrigeration contractors
  • Hospital and healthcare HVAC contractors
  • AMC-focused service companies

Not for

It is not the right fit if.

  • You plan to send offers to a service list that never asked, and you have not checked the platform's current rules.
  • Technicians use their own numbers, and a customer's chat and photographs would leave with them.
  • Nobody answers the number in the rush, so a photograph of an error code would sit unread.

How it works

How the whatsapp marketing work runs

The work itself, in order. How an engagement starts, from your brief to a written scope, is set out on our method page.

  1. 1

    Read the chats you already have

    We read how customers write to you, which questions repeat and where a chat goes quiet. The repeated questions decide what gets automated first.

  2. 2

    Sort the list and the permission

    Contacts who asked to hear from you are separated from numbers that only sit in a phone book. We agree the wording new contacts will see before they say yes.

  3. 3

    Choose the app or the API

    One phone and a small team can stay on the ordinary app. Several people on one number, templates or a CRM link need the API through a provider, which is its own piece of setup work.

  4. 4

    Write the replies and the plan

    The greeting, away message, saved replies and handover rule are written in your words and approved by you. The message plan and its templates follow.

  5. 5

    Connect the record and test

    Each link carries its source line and each chat lands in the CRM. We test on real phones, including a customer who asks for a person.

  6. 6

    Read the unanswered questions

    A question the first reply could not answer becomes a new saved reply or a fixed handover. Stop requests are watched too, with the number's quality rating where the API is used, since both show a message plan that has gone too far.

Proof

What happened when owners fixed this.

Real clients, the work we did, and the result as it was recorded. Where no number was recorded, none is claimed.

Where this fits

Three pieces of sales work, in this order.

This work sits inside sales process design, at stage 0, foundation. The audit comes before it, and sales management keeps it running.

  1. Step 1

    Sales audit

    Find where deals are being lost and what to fix first.

    Start here if you cannot say where orders are lost.

  2. Step 2 · you are here

    Sales process design

    One written way to sell, from first enquiry to repeat order.

    Start here if every salesperson sells differently.

  3. Step 3

    Sales management

    A target, a review routine and someone who owns the number.

    Start here if the team has targets and no routine.

FAQ

Questions owners ask before they call.

Not here? More answers, or ask on WhatsApp.

Tell us what you need
Should technicians use their own numbers with customers?
It is convenient, and it costs you the customer when they leave. Keep the company number as the channel of record, and add technicians to a site group where they need to be. The history stays with the business.
How often can we message our service list?
Rarely. A reminder before the season, a renewal note when a contract is ending, and something genuinely useful if there is one. Anything more and the list stops opening your messages, which is the only asset here.
A customer wants a price for a gas top-up from a photograph. What do we say?
A band is possible only for a standard job. A low gas level may mean a leak, and that needs a visit. Say so, give the visit charge if you have one, and record what was said before the technician goes.
How do we tell AMC customers a contract is due without it sounding like a sales push?
Send a plain notice with the contract end date and what it covers, and a way to ask questions. Send it only to AMC customers who agreed. Leave out urgency and discounts, which read as pressure.
How soon will we see results?
It depends on the trade, the channel and what is already in place. After we have read your brief and spoken to you, we say what we would expect to move first and how it will be measured against the baseline. Nothing here is guaranteed.
Who will actually do the work?
The person you speak to before anything starts. We work from one office in Nagarbhavi, Bengaluru, with no account managers in between.
What do you need from us?
Your brief, and a conversation. After that, access to whatever this work touches, such as your website, your accounts or your enquiry record, and time with the people who handle your enquiries.
What if we are not happy with the work?
Tell us and the plan changes. Everything is reported against the baseline, so a number that is not moving is visible to both sides. The term is in your written scope, and the refund and cancellation policy sets out the rest.
