Best practices

From savings to sustainability: practices we see paying off in the field. None require buying a product; most are changes of routine you can start today.

Energy savings

The biggest losses hide in the most ordinary places

The big difference usually comes from operating hours and setpoint discipline, not exotic technology. The order matters too: see first, then set rules, then measure.

01Measure the current state firstAny rule set without knowing which unit runs when is a guess. Start by recording operating status and, where possible, consumption.

02An end-of-day shutdown ruleDon't leave shutdown to whoever leaves last. Define schedules and bulk shutdown; notify someone about anything left on.

03Define a setpoint bandIn cooling, a 24–26 °C band protects comfort in most spaces. Limit settings outside the band; let users stay free within it.

04A separate programme for empty roomsMeeting rooms, storage and rarely used areas don't need the same programme as fully occupied space.

05Sun and door disciplineShading on sunlit façades, and care with open-door cooling at store entrances: consumption won't drop while the load doesn't.

06Clean filters, clean coilsA dirty filter delivers the same comfort by running longer. Maintenance is part of saving.

A savings figure is a calculation, not a promise

What the calculator gives is a potential based on assumptions. The real impact is measured after the rules go live, by comparing periods with similar weather and usage.

Maintenance

Get planned maintenance right

A mid-season breakdown is the most expensive kind: it arrives when service teams are busiest and stops the business on the hottest day. Maintenance exists to make that day never happen.

01Service before the seasonCooling maintenance in spring, heating checks in autumn; the system should enter its hardest day prepared.

02Set the filter rhythm by environmentIn offices a check every 2–3 months usually suffices; stores, restaurants and dusty spaces need monthly checks.

03Clean drains at the start of summerA blocked pan or drain line is the most common cause of indoor units dripping; clean before complaints start.

04Let the outdoor unit breatheKeep material away from it; have a fouled coil washed before the season.

05Have measured values recordedA visit closed without pressures, temperatures and currents written down burns the chance to compare next time.

06Don't settle for a reset on fault codesNote the code and unit number. A recurring code is the most valuable input to the service conversation.

Leak-check obligation

Systems holding 5 t CO₂e or more of refrigerant carry periodic leak-check and record obligations. You can calculate your system's CO₂ equivalent with the refrigerant tool.

Remote control & monitoring

Authority, limits and alarm discipline

The value of remote control is not sending commands but building order. In a well-set-up system, who may do what and which alarm reaches whom is decided up front.

01Separate authority from the startWho monitors, who changes setpoints, who manages schedules — write it down. Full rights for everyone is easy, and untraceable.

02Limit instead of lockingFully locking controllers breeds complaints. Define a setpoint band; users stay free inside it.

03Fewer alarms get seenDon't alarm every deviation. Build an alarm → owner → closure flow and prune false alarms regularly.

04Compare branchesWatch same-type branches side by side; the outlier reveals itself without touring sites.

05Enter the holiday calendar up frontPublic holidays are the most forgotten days of the year; load them into the annual schedule at setup.

06Know the limits of IR controlA split AC doesn't acknowledge commands; read "command sent" together with the room temperature.

Predictive maintenance

No prediction without data

Predictive maintenance isn't a feature you buy; it's a discipline you build. It starts with regular records and becomes trustworthy as rules are verified in the field.

01Start with recordsNo rule works until fault code history and operating status are recorded consistently. The first investment is always data.

02Watch trends, not just thresholdsThe fault code is the last step. Protection-trip frequency and pull-down time speak much earlier.

03Turn signals into casesRecord findings as observation, probable cause, recommended check and verification; a bare alarm produces no work in the field.

04Feed back false alarmsClose unverified cases with the reason noted. Rules only improve through this feedback.

05Resist automatic interventionAt first, the system proposes and the technical team decides. A system that changes settings by itself loses trust.

06Know what's unsupportedData your brand doesn't expose is "unknown", not "healthy". Ask for the monitorable signal list in writing.

Sustainability

Manage carbon with data too

In HVAC, sustainability hides in two places: the energy consumed and the refrigerant itself. Both can be measured; both can be managed.

01Treat leaks as a real costRefrigerant leakage is both a capacity and a carbon loss. Keep periodic leak checks recorded.

02Consider low-GWP refrigerantsOn new projects, weigh low-GWP options such as R32 together with their safety rules.

03Don't throw heat awayIn buildings that heat and cool at the same time, heat-recovery VRF moves heat from one zone to another.

04Size correctlyAn oversized system overconsumes for its whole life. "Let's go one size up" is not a sustainable decision.

05Extend equipment lifeRegular maintenance extends service life. Early scrappage throws away the carbon embodied in manufacturing.

06Base claims on measurementUse measured, not estimated, energy in carbon reporting; verify reduction claims under similar conditions.

The price of one kilogram of leakage

R410A's global warming potential is 2,088: one kilogram of leakage is roughly 2.1 t CO₂e. For R32 the figure is 675 (≈ 0.7 t). Leak prevention is the cheapest carbon abatement there is.
