Why your aircon needs regular servicing
An air conditioner quietly collects dust, mould and grime inside — on the filters, coils, fan and drainage line. Left unserviced, it cools less effectively, uses more electricity, recirculates allergens and is far more likely to break down. A regular aircon service keeps it running efficiently, extends its lifespan and protects your warranty.
How often should you service your aircon?
- Once a year for a typical home unit — ideally in spring, before the cooling season.
- Twice a year for heavy domestic use or units that also heat in winter.
- Every 3–6 months for offices, shops and commercial units that run all day.
Cleaning the filter yourself every few weeks helps, but it doesn’t replace a full professional service.
What’s included in a professional aircon service?
A proper service goes well beyond a filter rinse. At Van Biljoens it includes:
- Filter clean or replace — restores airflow and air quality.
- Coil cleaning — evaporator and condenser coils cleaned for efficient heat transfer.
- Gas (refrigerant) check — levels tested and topped up if needed.
- Drainage check — clearing the condensate line to prevent leaks and mould.
- Electrical and component check — connections, fan and compressor inspected.
- Performance test — confirming the unit cools to spec.
Signs your aircon needs a service now
- Weak or warm airflow
- Higher electricity bills than usual
- Musty or unpleasant smells
- Water dripping from the indoor unit
- Unusual noises or short-cycling

Frequently asked questions
How often should an air conditioner be serviced?
Once a year for a typical home unit, twice a year for heavy use, and every 3–6 months for commercial units that run all day.
What does an aircon service include?
A full service covers filter cleaning, coil cleaning, a refrigerant (gas) check, drainage clearing, an electrical and component inspection, and a performance test.
How much does an aircon service cost?
It varies by unit type and location — contact us for a quote. Regular servicing is far cheaper than the repairs caused by neglect.
Can I service my aircon myself?
You can clean the filters yourself, but coil cleaning, gas checks and electrical inspections should be done by a qualified technician.
What happens if I never service my aircon?
It cools poorly, uses more power, can develop leaks and mould, and is far more likely to suffer an expensive compressor failure.
