Split System Cleaning · Coffs Harbour
Coffs Harbour homes losing cooling capacity in summer often turn out not to need a refrigerant top-up at all — the fan barrel and evaporator coil are caked with mould, dust and grime that restrict airflow through the system. A chemical bag deep clean restores capacity without touching the refrigerant circuit, and Coffs Harbour's coastal humidity makes contamination build faster here than in dry-inland positions.
Split system deep cleaning across Coffs Harbour
The Coffs Harbour humidity load — 2 to 3 km coastal band plus tropical summer conditions — drives faster indoor-unit contamination than dry positions produce. Fan barrel mould, evaporator coil grime and biofilm buildup all develop faster on Coffs Harbour installations, and the presenting symptom (reduced cooling capacity) often gets misdiagnosed as low refrigerant by contractors who skip proper inspection. FHC starts every cleaning call with actual behaviour observation before recommending the clean.
Chemical bag cleans on Coffs Harbour installations run $140 to $200 per unit depending on system type, and take 30 to 60 minutes for a standard split system — longer for heavily contaminated systems or unusual configurations. Multi-unit households can be quoted for bundled cleans on a single visit. Every clean is documented in a written service report on completion.
What FHC delivers on every split system cleaning
A comprehensive chemical bag clean is a full maintenance clean of a split system, not a basic general service. Where a general service checks filters, coils and refrigerant charge in a broad way, a chemical bag clean strips the indoor unit down to the fan barrel, uses a purpose-designed chemical process to remove mould, dust, grime and biofilm from the fan barrel and evaporator coil surfaces, cleans the filters, and includes drain and condensate checks, airflow verification and general operating checks. The distinction matters because a system that is failing to cool effectively is often not low on refrigerant — it is caked with contamination that restricts airflow through the evaporator.
Typical timeline is 30 to 60 minutes for a standard split system; heavily contaminated systems or unusual system types can take longer. Typical price is $140 to $200 per unit depending on the specific system type being cleaned. FHC recommends the chemical bag clean where the unit shows visible mould or dust build-up on the fan barrel or evaporator, where a customer reports musty smells, or where cooling capacity has dropped noticeably without a specific fault code.
The service is carried out by ARCtick-licensed technicians (RTA AU069269), and FHC also holds $5 million public liability insurance covering the work. Every clean is documented in a written service report on completion covering what was found and any recommendations. A 12-month workmanship warranty applies where conditions apply.

Frequently asked
How do I know if my Coffs Harbour split system needs a chemical bag clean or just a service?
Signs the unit needs a deep clean rather than a basic service: musty smells when running, visible mould or dust on the fan barrel or evaporator, noticeably reduced cooling output despite otherwise normal operation. If those signs are present, a chemical bag clean is typically the right recommendation. FHC assesses on inspection and recommends honestly.
How often should a Coffs Harbour split system need a chemical bag clean?
Depends on usage and exposure. Systems in humid, dust-heavy or high-use environments need cleaning more often than lightly used systems in dry positions. As a rule of thumb, if a system has not had a deep clean in three years and you're noticing musty smells or reduced capacity, it is probably due.
