HVAC companies · Customer retention

Keep the AMC from lapsing quietly in March.

Retention for an HVAC company is the maintenance contract that renews and the past customer who calls you rather than searching again. GullySales builds the renewal list from your contract end dates and sets the pre-summer reminder that reaches every customer you have ever serviced.

What customer retention means

Customer retention is keeping an existing customer buying again rather than losing them to a competitor after the first purchase, usually cheaper than winning a new customer. GullySales sets a routine of check-ins and renewal reminders aimed at customers before they show signs of leaving.

For HVAC companies

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

  • “A lapsed AMC is not cancelled, it is forgotten”

    Almost nobody rings to end a contract. It simply runs out in March, nobody calls, and in June the customer finds a new company during a breakdown.

  • “The most valuable message of the year goes out before the first hot week”

    A service reminder read while the AC is still switched off reaches a customer with no emergency and no competitor on the phone. In June the same message is too late.

  • “Retention here is capacity, not loyalty”

    A renewed contract fills technician time in the quiet months, which is reason enough to discount it. A healthy AMC book is what carries a company through the monsoon.

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. A contract book sorted by end date

    Every AMC listed with its end date, value, site, units covered and the person who signs, pulled out of files and spreadsheets into one view.

    Result: You can see three months of renewals at a glance.

  2. A renewal call made before the contract ends

    A named person calling each customer ahead of the end date with the renewal amount and the service history to hand.

    Result: The contract is renewed while the customer still has cover.

  3. A pre-summer reminder to everyone you have serviced

    A message and a call list covering past customers with no live contract, offering a check before the season begins.

    Result: Quiet months turn into booked visits.

  4. Off-season work built for the monsoon

    Duct cleaning and preventive checks priced to keep technicians busy, offered to the customers already on your list.

    Result: Fewer idle weeks between the seasons.

  5. An AMC pitch handed over with every completed installation

    A written offer given at handover with the first year's cover priced and explained in plain terms.

    Result: The installation customer becomes a contract customer on the same day.

  6. A win-back round for contracts that already lapsed

    Customers whose cover ended last year contacted directly, with the units on record and a reason to come back.

    Result: Old customers return before they get used to somebody else.

  7. Renewal rate and repeat work read against the baseline

    Contracts renewed against contracts due, repeat work from past customers, and revenue from the contract book, measured against the baseline recorded before work started.

    Result: You can see whether the contract book is growing or leaking.

How the result is measured

  • Retention rate
  • Repeat purchase rate
  • Customers won back

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

Work it out from your records

Your contract book and job cards show which AMCs are due, which lapsed and which units are overdue.

AMC end dates in order
Sort every maintenance contract by end date and mark each as renewed, called, not yet called or lapsed. Start the calls well ahead of the date, not in the week the contract ends.
Last season's contracts: renewed, lapsed, cancelled
For contracts that ended last season count how many renewed, how many simply lapsed and how many were cancelled. Lapsed is the group to reach, since nobody refused them.
Installations with no AMC offered
List units you installed and note whether an AMC was offered at handover. Those without are customers whose first service call may well go to someone else.
Units by make and last service
Group units by make and capacity and record the last service date. A cassette unit and a split AC need different checks, so keep the lists apart before the pre-summer reminder.
Repeat callbacks for the same fault
Search job cards for the same unit coming back with the same fault. A callback rate on one technician or one make is more useful than a score on a review site.
Customers by building or locality
Group customers by apartment tower or locality. A cluster of past customers in one building is where a single visit or a neighbour's word can bring in several more.

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 have no AMC to offer, so there is nothing to renew when the installation guarantee ends.
  • The technician who knows each customer plans to start on their own, and you have not yet written down the book.
  • You plan to discount the AMC without knowing why the customer is leaving, which cuts the price and not the complaint.

How it works

How the customer retention 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 records

    Your sales and billing records are read for repeat purchase, the normal gap between orders and the customers who have gone quiet. The record-keeping gaps found here are listed.

  2. 2

    Ask why they stopped

    A small set of lapsed and current customers is called with your team's consent, and asked plainly what changed. The reasons are sorted into price, service, competitor and circumstance.

  3. 3

    Build the strategy

    The written plan sets priority groups, touchpoints, offers, owners, consent rules and a target.

  4. 4

    Align existing tactics

    Each retention activity you already run is mapped against the plan, then kept, changed or dropped.

  5. 5

    Start with one group

    The plan goes live for the most valuable at-risk group first, with a held-back comparison group, before it widens.

  6. 6

    Review against the baseline

    Retention is compared with the baseline recorded before work began. How often you are reported to is agreed in writing.

Where this fits

Three pieces of sales work, in this order.

This work sits inside sales process design, at stage 7, after the sale. 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 we discount to keep an AMC customer?
Sometimes, and it is often worth it. A renewed contract fills technician time you are paying for anyway and keeps the breakdown call coming to you. Work out what an idle week costs before deciding the discount is a loss.
How do we stop an AMC lapsing when the customer never answers?
Call before the end date rather than after, and try a different hour of the day. Record each attempt against the contract. If there is still no answer, send the renewal terms in writing so the lapse is at least their decision.
A customer wants to cancel the AMC after one breakdown. What should we do?
Visit and listen. Show what was found, what was done and why it happened. If the fault was ours, say so and put it right. Offer to review the contract terms, such as the visit schedule, rather than cutting the price. Record the reason either way.
Our technician knows every customer and may start on their own. How do we protect the book?
Keep each customer's unit details, history and contact in the company's records, not in a personal phone. Rotate who visits so that customers know the company. Check the technician's agreement on customer contact. Give customers a reason to stay: a clear record and a reminder.
How much does it cost?
There is no price list, because the work differs by business. The fee is scoped after we have read your brief and spoken to you, and put in writing before anything starts, split into our time, your media spend and production.
How long is the contract?
The term is agreed in writing after we have spoken, along with the fee and the reporting. It is never a default twelve months, and renewal is decided on the numbers against the baseline recorded at the start.
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.
