ACs move heat, not “cold.”
Your unit absorbs heat indoors and releases it outside. Good airflow helps that heat transfer happen efficiently.
Did you know?
Small AC habits can make a big difference.
Air conditioners work hard in South African homes and businesses. A few simple checks can improve comfort, reduce strain and help you spot when professional service is needed.
Dirty filters make the unit work harder.
Clogged filters reduce airflow, lower efficiency and can allow dirt to build up where it should not.
Bigger is not always better.
An oversized unit can cool quickly but may not dehumidify properly, leaving the room less comfortable. Work out the right size.
Outdoor units need breathing room.
Leaves, dust and clutter around the condenser can restrict airflow and reduce performance.
How to take care of the unit
Simple care between professional services.
Keep airflow clear
Do not block indoor return air or supply airflow with curtains, furniture or stored items. Keep the outdoor unit clear of leaves, dust and plants.
Check filters often
Inspect filters monthly during heavy use. Some split-unit filters can be cleaned every two weeks, depending on dust levels and manufacturer guidance.
Book professional maintenance
Coils, drains, refrigerant checks and electrical connections should be inspected by a qualified technician as part of scheduled maintenance.
Cleaning
Clean your mid-wall split air conditioner filters.
Clean filters help improve airflow, cooling performance and indoor air quality. During heavy use, check the filters every 2-4 weeks, or at least once a month for general upkeep.
What you will need
Soft microfibre cloth, vacuum cleaner with brush attachment, mild detergent, lukewarm water, a bowl or basin, gloves and a step ladder if required.
- Switch off first. Turn the AC off with the remote, then switch off the power supply or unplug the unit where safe and practical.
- Open the front cover. Lift the front panel gently from the bottom edge until it locks open.
- Remove the filters. Slide or lift the mesh filters out carefully without bending the frame.
- Remove loose dust. Use a vacuum cleaner with a brush attachment, or gently tap the filters outside.
- Wash if needed. Rinse with lukewarm water. If heavily dirty, use a mild detergent. Avoid boiling water, harsh chemicals, abrasive brushes and pressure washers.
- Dry completely. Shake off excess water and leave the filters to air dry in shade. Do not expose them to direct sunlight or heat.
- Reinstall and close. Slide the filters back into position, close the front panel securely, then switch the unit back on.
Optimal performance
Get better comfort from the system you already have.
Close doors and windows
Air conditioners perform best when they are cooling a controlled space. Open windows and exterior doors let heat and humidity back in.
Use curtains and blinds
Blocking direct sun during hot parts of the day reduces heat gain and helps the unit maintain temperature more easily.
Set a sensible temperature
Choose a comfortable setting instead of forcing the lowest possible temperature. Small changes can reduce strain and energy use.
Use fan mode wisely
Auto fan settings usually help the system manage cooling cycles. Ceiling or room fans can help distribute cool air in occupied areas.
