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.
Scope, fee, reporting and term are agreed in writing after we have read your brief and spoken to you.
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.
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.
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.
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.
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.
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.
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.
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 him 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.

How it works
From your first message to the first report.
No open-ended retainer. Every step gives you something in writing.
First
Your brief
You tell us what you need in a few short steps: your business, what you want, where enquiries come from and how they are handled.
After the brief
A conversation and a written scope
We read it, then talk with whoever handles your enquiries. If you want our help, the scope, the fee and the reporting come in writing, and nothing starts before you have read them.
Before work starts
Baseline recorded
The numbers this work is meant to move, such as enquiries, quotations, orders, visits or renewals, written down so every later report has an honest comparison.
After the baseline
The first fix goes live
The fix we agreed to start with is put in place and measured against the baseline, whether that is a reply, a follow-up, a page, a listing or the handover between marketing and sales.
As agreed
Report against the baseline
What moved, what did not, and what changes next, in plain words. How often you get it is set in writing before work starts.
At renewal
Renew on the numbers
The term ends and you decide whether to continue from the results. The length is agreed in writing before anything starts.
How the referral marketing work runs
- 1
Understand your margin and customer relationship
We agree what reward is genuinely sustainable and appropriate for your business and customer type.
- 2
Audit existing informal referrals
We check how much word of mouth already happens, to size expectations for the formal programme realistically.
- 3
Design the offer and mechanism
A specific reward and an easy sharing method are built and tested.
- 4
Implement and promote
The programme is surfaced at the right moments in your customer journey.
- 5
Measure and adjust
We track referrals and conversions, adjusting the reward or promotion if uptake is low.

Why us
Why owners pick GullySales over an agency.
Marketing and sales, as one job
Most agencies stop at the enquiry. We also fix what happens after it: the reply, the follow-up, the quote and the CRM.
The person on the first call does the work
No account managers in between. You are never handed to someone you have not met.
A baseline before anything starts
Your numbers are written down on day one, so every later report compares against something honest.
The fee in writing, split three ways
Our time, your media spend and production on separate lines. You always see what goes to us.
No guarantees we cannot keep
The term is agreed in writing and never a default twelve months. We never promise a ranking or a lead count, because nobody controls those.
One office, and we say so
