Turning installed equipment into a contract

Maintenance doesn’t sell when the customer needs it — it sells on installation day, when they’re satisfied and the technician is still at their home.

What works, in order:

1. Explain at delivery that the equipment needs periodic cleaning, what happens if it’s not done — performance loss, higher consumption, bad odor, warranty risk — and when the first cleaning will be.
2. Set the date right then and there, not just promise to call later.
3. Offer the plan: two cleanings per year, priority service, and repair discounts, billed monthly.
4. Record everything in the customer’s profile, linked to the equipment.
5. Notify in advance, fifteen days before the date, with the suggested time.

The monthly plan converts much better than the annual package for the usual reason: a small charge on the card isn’t a decision, but a large one at once is.

PMOC: the obligation that becomes a sales argument

In Brazil, air-conditioned collective-use environments are subject to maintenance and air quality requirements, with a maintenance, operation, and control plan and a technical responsible person. Rules and scope vary by environment type and applicable standard, and it’s worth confirming each client’s classification with the company’s technical responsible.

For sales, the effect is huge: office, clinic, school, gym, restaurant, and commercial buildings aren’t buying comfort — they’re fulfilling an obligation. This changes the conversation completely. It stops being "want to clean the air?" and becomes "is your company’s maintenance plan up to date?"

What corporate clients need and almost no climate control company delivers organized: report of each visit, equipment-by-equipment record, report signed by the technical responsible, and a calendar they don’t have to remember. Those who deliver this aren’t compared by price — they’re compared by the risk of not having it.

Warranty, replaced parts, and the conversation that avoids rework

Much of the friction in climate control arises from an expectation no one aligned: the customer thinks everything that happens to the unit in the next months is covered by warranty, and the company thinks it was obvious it’s not.

What needs to be written at delivery and repeated by message:

• What the manufacturer’s warranty covers and for how long, which is the manufacturer’s matter, not yours.
• What your installation warranty covers — leaks in soldering, poorly sloped drainage, mounting — and for how long.
• What is not covered: accumulated dirt, lack of cleaning, power outages, use outside specifications, third-party damage.
• That lack of maintenance can affect the warranty of the equipment, which is true for many manufacturers and is the best honest argument for the contract.

On the operational side, every replaced part must be recorded with date and cost in that customer’s history. Without this, the company might replace the same capacitor twice in one year without realizing there’s a bigger problem, and argue with the customer about what was done last time without proof.

Before and after photos of each visit solve almost all such disputes, take thirty seconds, and become sales material for the next quote.

One year in numbers

Company with two technicians and one van, serving residential and small commercial clients.

• 214 installations in the year, average ticket R$ 780 = R$ 166,920
• Maintenance sold back to these clients: 11 — 5% of the installed base
• One-off maintenance from clients who called on their own: 148, ticket R$ 190 = R$ 28,120
• Emergencies and repairs: 96, ticket R$ 320 = R$ 30,720

Revenue: R$ 225,760, with 74% coming from installation — the most contested and lowest margin part.

The company started recording equipment and cleaning dates on every installation, scheduling the first maintenance at delivery, and notifying fifteen days before. The following year, with a similar number of installations:

• Maintenance: 331, with 189 from the installed base
• Active monthly contracts: 63, between residential and commercial, averaging R$ 95/month = R$ 71,820/year
• Repairs from maintenance clients, with better margin: R$ 41,600

Revenue: R$ 348,240 — R$ 122,480 more, without a new client or advertising. Most importantly: recurring revenue went from zero to 21% of turnover.

Summer can't last all year

Every climate control company knows the curve: November to March unable to serve everyone, June to August with the team idle. Maintenance is the only thing that solves this because it can be scheduled.

Three decisions flatten the curve:

• Schedule contract cleanings for the cold months. This fills exactly the empty weeks, and the customer accepts because they’re not using the unit.
• Sell pre-summer checkups in September and October, with the honest argument: those who check before don’t go without air in December waiting three weeks for service.
• Use winter to reactivate the old base, contacting those installed two or three years ago who never returned.

Companies that do this work year-round with the same team. Those that don’t hire in summer, fire in winter, and never build a team.

Emergency calls and their value

At the peak of heat, customers with broken units aren’t comparing prices — they’re calling until someone says they’ll come today. This is the highest margin revenue of the year and the one most lost due to disorganization.

What decides:

• Respond quickly, even outside business hours. Those who respond in minutes get the job.
• Give a realistic time window, and notify when the technician leaves.
• Know the customer’s history before responding. If they’re already in the base, the technician arrives knowing which unit it is, what was done last time, and what parts were replaced.
• Charge for urgent travel, which is standard in the sector and accepted by customers.

When the team grows, information gets lost

With one technician, everything fits in their head. With three, the customer calls and no one knows which unit it is, who installed it, what was done last visit, or what was agreed. This is when the company starts to seem disorganized just as it’s growing.

The minimum that needs to be in one place, accessible to anyone: customer profile with equipment, history of all visits with what was done, before and after photos, valid warranties with expiration, and pending items. Without this, each technician gives a different answer and the customer notices.

Five mistakes that cost contracts

• Not recording the equipment at installation. Without this, there’s no maintenance to sell later.
• Promising to call to schedule cleaning. Doesn’t call, and the customer looks elsewhere the next year.
• Giving installation price over the phone. Either lose the sale or lose margin.
• Treating commercial like residential. Companies buy compliance and reports, not comfort.
• Leaving winter to chance. Maintenance should be scheduled then.

Key metrics to track

• Percentage of installations with equipment and cleaning date recorded — below 90%, there’s no base to sell to.
• Maintenance sold to the installed base, versus those who came on their own.
• Active contracts and monthly recurring revenue.
• Revenue distribution by month, measuring if seasonality is being flattened.
• First response time on emergency calls.
• Customers who returned for a second unit, which is the cheapest sale there is.

Climate control is a sector where the hard sale is the first one and the easy sale is the one no one makes. Recording equipment, scheduling cleaning at delivery, and notifying before the heat turns a company that restarts every summer into one that works year-round with the base it already built.
