HVAC companies · Referral marketing

Get the builder and the society secretary to hand you the work.

Referrals for an HVAC company come from builders, interior contractors, electricians and society secretaries as much as from happy homeowners. GullySales works out which relationships are worth building, writes the introduction they can pass on, and sets what a fee looks like when one is fair.

What referral marketing means

Referral marketing is asking an existing customer to recommend you to someone they know, usually with a reward for both sides. It differs from a loyalty scheme because it brings in a new customer rather than a repeat purchase. GullySales builds the ask and the reward into a point where a customer is already satisfied.

For HVAC companies

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

  • “One society secretary is worth a hundred homeowners”

    An apartment block with two hundred flats has one person everybody asks who to call. Service that building well and the referrals arrive without any advertising.

  • “The interior contractor decides the AC before the owner does”

    By the time a homeowner thinks about cooling, the false ceiling is already drawn. The contractor and the electrician have an HVAC company they call.

  • “A facilities head's recommendation travels to other buildings”

    Facilities managers move jobs and talk to each other. One well-run contract in an office park gets mentioned at the next building's tender.

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 partner list of builders, contractors, electricians and societies

    The people asked about cooling in your service area, listed with the buildings they work on and who to speak to.

    Result: You know whose door to knock on this month.

  2. A capability note a contractor can forward

    One short document with the systems you install, the brands you work with, your service area and your response commitment, in a file that opens on a phone.

    Result: Your name reaches the homeowner through the person already on site.

  3. A written arrangement for trade referrals

    What you pay or discount for referred work, how it is invoiced and when it applies, agreed with each partner before the first job.

    Result: Nobody negotiates a commission after the installation is done.

  4. A homeowner ask at the end of a good job

    A short, specific request from the technician after a repair that went well, asking the customer to mention you in the building group.

    Result: Your name enters the chat where every breakdown is discussed.

  5. A society outreach round before the season

    An offer taken to the secretary covering common-area units, with a separate rate for individual flats in the block.

    Result: One conversation opens a whole building.

  6. Referral source recorded on every enquiry

    Each new job tagged with who sent it, and followed through to the value of the work.

    Result: You can see which partner is worth a visit and which is worth dropping.

  7. Referred work read against the baseline

    Referrals received, what share converted and what they were worth, set beside the baseline recorded before work started.

    Result: You can tell whether the partner round beats the advertising.

How the result is measured

  • Referrals received
  • Referral conversion rate
  • Cost per referred customer

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

How referrals reach an HVAC contractor

An HVAC job is passed on by builders, interior contractors, electricians and society secretaries before the owner calls.

Builders and project managers
Chiller and VRF capacity is fixed at the design stage. Send the project manager a note on the load calculations you check, the plant room space you need and the commissioning documents you hand over.
Interior contractors
A contractor building the false ceiling needs the ducting and refrigerant pipe route first. Send a layout sheet marking the indoor unit positions to leave open before the ceiling closes.
Electricians
An electrician fitting split ACs gets asked who can do the gas piping and service. Give the electrician a laminated card with your name, the brands you service and how to book a call-out.
Society secretaries
A secretary gets requests for a technician before summer. Offer a notice for the society board with AC service rates and visit dates, and ask permission to put it up.
Referrer on the job card
Write the referrer on the job card and again on the invoice. When an AMC is signed, note the source so the builder or electrician is thanked for the long relationship, not the first visit.
What never to do
Never cut corners on a referrer's job to protect the price. A poorly sized unit installed for a builder's client reaches the rest of the project before you hear about it.

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 not finished a job a builder or secretary can visit, so a request for an introduction has no proof behind it.
  • You plan to pay a commission to a builder or a contractor and have not checked the rules that apply to you and them.
  • A referred client expects a lower price than you quoted, and you have not decided whether you can give it.

How it works

How the referral 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 margin and the relationship

    We work out what a new customer is worth and what you can pay to get one, then check whether customers know others like themselves.

  2. 2

    Find the referrals you already get

    Your invoices, call notes and WhatsApp threads show who already sends people to you, and who they are. That sets the starting point and the first people to ask.

  3. 3

    Write the offer and the rules

    The reward, the definition of a valid referral and the payout steps are agreed in writing before anything is shown to customers.

  4. 4

    Build the share path and the record

    The message, the link or code and the referral sheet are built. Your team tests a referral end to end, from forward to reward.

  5. 5

    Start with your best customers, then widen

    The first asks go to people who have already praised you. What they say about the offer decides what changes before it reaches the wider base.

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
Is paying a commission to a builder or contractor acceptable?
It is common in construction and nothing stops you doing it, as long as the customer's price is not quietly inflated to pay for it. Agree it in writing, invoice it properly, and account for it. Your CA will tell you how to treat it.
How do we approach a society secretary without annoying them?
Go with something they need rather than a request. An inspection of the common-area units, or a written note on what the block's systems will cost to maintain, gives them something to take to the committee.
Who answers a warranty claim on a unit that a contractor installed and referred to us?
Write it down at the start: the installer handles faults that come from installation, and you handle those covered by your own warranty or the brand's. Give the customer one number to call, so the referrer is not blamed for a problem they did not cause.
A referred client wants a lower price than we quoted. What do we do?
Quote on the load calculation and the unit, not on who sent the client. If the client cuts the specification to cut the price, say so in writing. Tell the contractor too, so the contractor does not feel sold around, and keep the written scope the same for both.
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.
