In Kariega's summer heat, an aircon breakdown at home is uncomfortable and at work it can stop the day. Regular servicing is the cheapest way to avoid both. Here is how often to service, what a proper service includes and what your staff can do between visits.

Quick answer

Service home aircons in Kariega once a year before summer, and office, practice and workshop units every six months because they run all day. Clean filters monthly in summer, keep outdoor units clear and shaded, and log faults and error codes so technicians can spot patterns. Server-room units should be checked more often.

The cost of a summer breakdown

When an aircon fails on a 38-degree day in Kariega, the cost is more than the repair bill. At home, it means sleepless nights and uncomfortable children. In an office, staff lose concentration, computers run hot and clients notice. In a medical or dental practice, it affects patient comfort. In a server room, it can mean equipment failure and downtime.

Most of these breakdowns are not sudden. Filters clog gradually, coils get dirty, gas leaks out slowly and capacitors weaken over months. A service catches these problems before the heat pushes the unit past its limit.

How often to service

Homes

Once a year is enough for most homes, ideally in October or November before the summer heat. If your unit also heats through winter, consider a second service in autumn.

Offices and practices

Every six months. Office units typically run eight to ten hours a day, five days a week, plus extra heat from people and equipment.

Workshops and industrial units

Every six months, sometimes every three or four months in very dusty environments. Dust from roads, yards and processes clogs coils quickly.

Server and comms rooms

Every three to six months, plus regular visual checks. These units often run 24 hours a day.

What a proper service includes

A quick filter clean is not a service. A thorough service should cover:

Indoor unit

  • Remove and clean filters
  • Clean the evaporator coil
  • Clean the blower wheel, which collects dust and mould
  • Flush and treat the drain tray and line
  • Check the louvre motor and display
  • Check the unit is level and secure

Outdoor unit

  • Clean the condenser coil
  • Remove debris from the fan and casing
  • Check the fan motor and blade
  • Check refrigerant pressures and temperatures
  • Test capacitors and contactor
  • Check electrical connections for tightness and heat damage
  • Check brackets, base and anti-vibration mounts

System

  • Measure supply air temperature
  • Check operation in cooling and heating
  • Note any error codes in the unit's history
  • Report anything that needs attention

What your staff can do between services

A few simple habits make a big difference:

  • Clean filters monthly in summer. It takes five minutes per unit and can be done by an office manager or facilities person.
  • Keep doors and windows closed when the aircon is on.
  • Set sensible temperatures. Around 23 to 24 degrees is comfortable for most offices. Setting units to 16 degrees does not cool faster and makes them work much harder.
  • Keep outdoor units clear. Do not store pallets, boxes or bins against them.
  • Report changes early. If a unit starts dripping, smells, makes noise or cools less, report it before it fails completely.
  • Log error codes. Take a photo of any code on the display and note the date. Patterns help technicians diagnose intermittent faults.

Shade and airflow for outdoor units

Many Kariega business premises have outdoor units on west-facing walls in full afternoon sun, or squeezed into narrow passages between buildings. Both reduce efficiency. A simple shade roof placed well above the unit, or relocating it to a better position during a future upgrade, can improve performance and reduce running costs.

Keeping records

For businesses with several units, keep a simple register: unit location, brand and model, installation date, service dates and any repairs. It makes budgeting easier and helps you decide when replacing a unit makes more sense than repairing it again.

When to replace instead of repair

Consider replacement if:

  • The unit is an older fixed-speed model with a failed compressor
  • It has needed several repairs in the past year
  • It uses an older refrigerant that is becoming hard to source
  • It has never cooled the space properly
  • Electricity costs are a concern, since modern inverter units are much more efficient

Homes in Fairbridge Heights, Vanes Estate and Despatch

For home aircons, the same principles apply at a smaller scale. Clean the filters monthly in summer, keep the outdoor unit clear and book an annual service before the heat. If your unit sits in the afternoon sun, shade helps.

Frequently asked questions

How long does a service take?

Usually 45 minutes to an hour per unit, depending on access and how dirty it is. For offices with several units, we plan the schedule to minimise disruption.

Can my staff clean the filters themselves?

Yes. Filters slide out easily and can be rinsed under a tap and dried. Coils, drains, gas and electrical checks should be left to a technician.

Does servicing really reduce electricity costs?

Yes. Clean filters and coils let the unit move heat efficiently, so it runs for shorter periods and the compressor works less hard.
