Servicing windows

Pre-monsoon tune-up windows are open through October. Weekday mornings fill first.

Cooling care that comes with readings, not guesswork

We service air conditioners for homes, studios and small premises — and we write the temperature and pressure readings down before and after, so you can see what the visit actually changed.

Book a service window Match a symptom first

Every visit ends with a short written note: what was cleaned, what was measured, and when the unit is due again.

Three service lanes

Pick the depth of work, not a package name

Most units need one of three things. Below is exactly what each lane includes, so you can tell whether a rinse will do or the coil genuinely needs to come apart.

Lane 01

Routine Service

The regular maintenance visit. Filters, fins, drainage and airflow, checked and cleaned before small problems turn into a repair bill.

Suits: units in normal use, serviced within the last year. Typical interval — every three months for a bedroom or living room, monthly for a room that runs all day.

Included in the visit

  • Filters removed, washed, dried and refitted
  • Evaporator fins vacuumed and combed straight
  • Drip tray wiped out and drain line flushed clear
  • Blower barrel brushed and checked for wobble
  • Supply and return air temperatures measured
  • Remote, thermostat and swing motor function tested
  • Outdoor unit fins rinsed and clearance checked

Lane 02

Deep Chemical Wash

A strip-down clean for units that smell, drip, or blow noticeably weaker than they used to. The barrel and coil come out so the grime behind them can actually be reached.

Suits: units that have gone two years or more without a deep clean, or any unit with a persistent musty smell. Typical interval — once every eighteen months to two years.

Included in the visit

  • Indoor casing opened and internals protected
  • Blower barrel removed and soaked
  • Coil treated with a non-acidic foaming cleaner
  • Drip tray and drain pan scrubbed and rinsed
  • Drain line pressure-flushed end to end
  • Fan bearing and motor mount inspected
  • Airflow and cooling delta re-measured after reassembly

Lane 03

Diagnostics & Repair

For units that cool poorly, cut out, trip the breaker or throw an error code. We find the cause first and tell you what it costs before anything is replaced.

Suits: any unit behaving differently to last month. Booked as a diagnostic visit; repair work is quoted on the spot and only carried out with your go-ahead.

Included in the visit

  • Manifold gauge reading on both service ports
  • Electronic leak trace along line set and joints
  • Capacitor, contactor and compressor draw tested
  • Sensor resistance and control board fault read-out
  • Refrigerant charge corrected with a logged pressure
  • Written fault note with the parts needed, if any

What the unit is doing, and which lane fixes it

Read down the left column for the behaviour you are seeing. If two rows sound familiar, book the deeper of the two lanes — it saves a second visit.

Common air conditioner symptoms, their likely cause, and the service lane that addresses them
What you notice Usual cause Book this
Weak airflow; the room takes hours to cool Loaded filters and a dust-caked blower barrel choking the air path Routine Service
Water dripping from the indoor unit Blocked drain line, or a bracket that has drifted out of level Routine Service
Musty smell for the first minutes after start-up Biofilm sitting on the coil and in the drip tray Deep Chemical Wash
Visible dirt or dark speckling on the coil fins Years of build-up behind the barrel, past the reach of a surface clean Deep Chemical Wash
Runs constantly but never reaches the set temperature Low refrigerant charge, usually from a slow leak at a flare joint Diagnostics & Repair
Rattling outdoor unit, or a remote showing an error code Loose fan mount, tired capacitor, or a sensor reporting out of range Diagnostics & Repair

How a visit runs

Six steps, every single call-out

Servicing happens above your furniture, so the order of work matters as much as the work itself. This is the sequence our technicians follow, without exception.

  1. Window confirmed the day before

    You get a two-hour arrival window and the name of the technician coming. If we are running late, you hear it from us first.

  2. Floor, wall and furniture covered

    Sheeting goes down and a catch bag goes up around the indoor unit before a single panel is opened.

  3. Readings taken before any work

    Supply air, return air and running pressure are recorded first. Without a starting number, nothing afterwards can be proven.

  4. The booked lane carried out

    Work stays inside the lane you booked. If we find something outside it, we stop, show you, and quote before continuing.

  5. Readings taken again and written down

    The same three measurements are repeated and added to your unit log alongside the first set, so the change is visible.

  6. Next service date agreed, not assumed

    Based on how the unit actually looked inside, we suggest an interval and leave it with you. No automatic renewals.

Readings are recorded at the unit as the work happens, not written up afterwards from memory.

Between visits

Four habits that stretch the interval

None of these replace a service, but together they keep a unit from arriving at its next visit in poor shape — and keep the running cost predictable.

  • Rinse the filters fortnightly

    Slide them out, rinse under a cool tap, shake off the water and let them dry fully before refitting. A damp filter is how a smell starts.

  • Keep the outdoor unit breathing

    Leave roughly half a metre of clear space around it and keep leaves, boxes and drying laundry away from the fan face. Restricted airflow shows up as high pressure and a higher bill.

  • Set it warmer than instinct says

    Twenty-four to twenty-five degrees with the fan on auto cools a room as effectively as a lower setting, and the compressor spends far less time at full load.

  • Run fan-only before you switch off

    Twenty minutes of fan-only dries the coil after a humid day. It is the single cheapest way to delay a chemical wash.

Questions

Asked before most first bookings

If your question is not here, add it to the booking notes and you will get a straight answer before we arrive.

How often does a home unit really need servicing?

A bedroom unit used at night is comfortable on a three-month routine service. A living room or studio unit running most of the day is better on a monthly filter visit with a quarterly full service. Units in dusty streets or near cooking areas load up faster and benefit from shorter intervals.

What is the actual difference between a routine service and a chemical wash?

A routine service cleans everything reachable with the casing open — filters, accessible fins, tray and drain. A chemical wash removes the blower barrel and treats the coil with a foaming cleaner, which reaches the grime packed behind the barrel that no surface clean can touch. Smell and weak airflow that survive a routine service are the signal to go deeper.

Do we need to move furniture before you arrive?

Clearing a metre of floor directly under the indoor unit is enough. We bring sheeting and a catch bag for everything else. If a wardrobe or shelving unit blocks access to the wall, tell us in the notes so the right ladder comes on the van.

How long does a visit take?

A routine service on a single split unit is usually inside an hour. A chemical wash on the same unit takes closer to two, because the barrel has to soak and the coil must be rinsed and dried properly before reassembly. Diagnostics depends entirely on the fault; we tell you as soon as we know.

Will you top up the gas as part of a routine service?

No, and you should be wary of anyone who offers to. A sealed system does not consume refrigerant. If pressure is low there is a leak, so we trace and fix it first and charge the system afterwards with the pressure recorded in your log.

Do you service units you did not install?

Yes — most of our work is on units installed by someone else. Any brand and model we can open, we will service. If a part is obsolete we will say so plainly rather than fitting a poor substitute.

What happens if you find a fault mid-visit?

We stop, show you what we have found, and give you the cost before touching it. Work outside the lane you booked never goes ahead on assumption. If you would rather think about it, we finish the booked work and leave the note with you.

Response
Enquiries sent before mid-afternoon are answered the same working day.

Monday to Saturday, morning and afternoon windows. Saturday mornings book out earliest.
Multiple units
List them in the notes. Servicing several units in one visit is quicker and quoted together.

We reply with a confirmed window and a price for the lane before scheduling anyone.
