HVAC companies · Email marketing
Remind a commercial client about their AMC renewal before they forget it exists.
Email marketing for an HVAC company is a short seasonal note about an AMC renewal or a pre-summer service, sent to commercial clients and past customers. It is not a newsletter. GullySales times it to the seasonal pattern this trade actually follows.
A 90-minute audit call and a written, scored report. Turnaround, reporting and term are agreed in writing after the audit.
What email marketing means
Email marketing is sending planned messages to a list of past and prospective customers who have agreed to hear from you. It suits offers, updates and staying in touch with someone who is not ready to buy yet. GullySales writes and schedules these emails and tracks who opens, clicks and enquires.

For HVAC companies
Where it usually goes wrong, and what we would do.
“Renewal reminders should arrive well before the deadline”
An email sent a month before an AMC lapses gives a facilities head time to process a renewal through their own approval process, which a last-week reminder does not.
“Commercial clients respond to documentation, not persuasion”
An email attaching last year's service record and response times supports a renewal decision better than a message that simply asks for one.
“Pre-summer maintenance tips build a reason to open the email”
A short, useful note on preparing an AC system before summer earns attention that a purely promotional email would not.
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.
Advance renewal reminder sequence
An email sent well ahead of an AMC's expiry, timed for a facilities head's own internal sign-off process.
Result: A renewal is processed before the contract lapses, not after.
Documentation-backed renewal emails
Past service visits and response records included with the renewal request, not just an ask.
Result: A facilities head gets the proof their approval process actually needs.
Pre-summer maintenance tip emails
A short, useful note on preparing a system before summer, sent ahead of the season.
Result: The email earns attention instead of being ignored as promotional.
Commercial client segment list
Past and current commercial clients organised separately from residential customers for relevant messaging.
Result: A commercial client receives documentation, not a residential-style offer.
Post-service follow-up email
A message sent after a completed job, closing the loop and setting up the next reminder.
Result: The client relationship continues past the single job.
How the result is measured
- Open rate
- Click rate
- Enquiries from email
Recorded as a baseline before work starts, so every later report has an honest comparison.
What must be in place first
What an HVAC company needs in place before it emails clients and past customers.
- A client record with equipment details
- List each site with the type of plant, tonnage, make, install date and AMC end. A pre-summer note that names the chiller or the split units is more likely to be read than a generic one.
- Commercial and residential on separate lists
- A facility manager wants AMC terms, response times and compliance. A homeowner wants a service slot. Keep two lists and two voices, and send the homeowner's slots by WhatsApp as well.
- A seasonal calendar in your own diary
- Mark when each client needs a pre-summer service, a pre-monsoon check or a winter shutdown, based on their own history. Write in time for them to plan the visit, not on the hot day itself.
- An AMC summary they can forward
- Prepare a one-page note listing equipment covered, visits, parts and breakdown terms, and exclusions. The facility head will pass it to purchase, so it must stand alone.
- A reply route that reaches the scheduler
- Use the company domain and route replies to the person who books technicians. A client who writes on a hot afternoon about a failing unit should reach a person, not a general inbox.
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 want a guaranteed Google ranking or a guaranteed number of leads. Nobody honest can promise either.
- You need enquiries by next week and have nobody to answer them.
- You want posts and reach reported, not enquiries and orders.
How it works
From your first message to the first report.
No open-ended retainer. Every step gives you something in writing.
First
Free audit call
90 minutes with whoever handles your enquiries: how they arrive, how fast they are answered, where they are lost.
After the call
Written, scored report
Six areas scored, fixes ranked by return and cost. If you want our help, the scope, the fee and the reporting come with it, in writing.
Before work starts
Baseline recorded
Enquiries by source, reply time, conversion and cost per order, written down so every later report has an honest comparison.
After the baseline
The first fix goes live
Usually the cheapest one on the report: reply time, a follow-up sequence or the marketing-to-sales handover.
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 work runs for HVAC companies
- 1
Assess
We look at how you show up in local search before summer and your reply time on calls and WhatsApp. We also count how many AMC customers are due for renewal.
- 2
Fix the profile and the reply
Google Business Profile completed with service areas and response time, and a routine so a summer breakdown call is answered the same day.
- 3
Build the AMC renewal system
Reminders sent to every customer before their contract lapses, so a renewal is not left to chance or a forgotten calendar entry.
- 4
Bring enquiries in ahead of season
Local search and advertising timed to start before the summer rush, not once it has already begun.
- 5
Win the commercial tender
Proposal and case-study material for office, mall and hospital tenders, built around energy efficiency and response time.
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.

- Result
- No numbers were recorded for this engagement. The work is described in full in the case study.

- The site rebuilt around booking
- Photography and one look
- Search work for destination searches
- Content a traveller reads
- Result
- Online bookings increased 35%
- Organic traffic increased 50% within six months

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
