Persistent musty odours
Odour can follow damp surfaces, obstructed drainage or dirty filter and coil areas. The remedy depends on what is causing moisture to remain. Perfume sprays are not a replacement for finding and correcting the source.
An unpleasant odour during the first minutes of operation can follow retained moisture, fouled filters or contamination around accessible indoor components. A burnt-plastic smell is different and demands an immediate shutdown.
We ask what the smell resembles and whether it disappears, grows stronger or occurs only after a period of non-use. Masking a persistent odour with perfume does not address the source.

The visit looks at filter condition, condensate handling, the accessible coil and whether the fan runs long enough to dry surfaces between cooling cycles. We consider the unit and nearby room conditions without making a health diagnosis.

Poor drainage can leave standing water after cooling stops. When checking an odour, we examine accessible pan and drain condition and consider whether water can leave as designed without backing up.
A hot-plastic or electrical burning smell requires the unit to be switched off where safe. This is not an ordinary cleaning request: electrical safety and possible damaged components must be addressed before operation resumes.
Separate a stale or damp odour from an acrid smell with electrical characteristics. The first may lead to investigating moisture retention and drainage; the latter requires shutdown and electrical assessment. The timing after starting or stopping the indoor fan helps locate what changes when the smell becomes noticeable.
Cleaning or correcting condensate problems may help where moisture is the cause. If wiring or components show heat damage, safety takes priority over deodorising; the affected circuit needs appropriate electrical assessment.
Record whether the odour is musty, chemical or burning and if anyone recently applied sprays to the unit. Switch it off and seek urgent attention for smoke or electrical burning.
Follow manufacturer cleaning guidance and monitor for recurring moisture rather than spraying disinfectant into a live indoor unit.
Stop using the unit if the odour resembles overheated plastic or insulation. Do not spray scented chemicals into the running intake to cover it.
Yes. Describe the sequence, error indications and system type when booking. The inspection determines whether the trouble is with settings, airflow, electrical controls or cooling equipment before a repair is recommended.
Appointment availability depends on the address, technician schedule and access to the equipment. We confirm the visit after reviewing your enquiry; the site does not promise a specific arrival time.
Not automatically. Poor cooling has several causes, and a sealed circuit should not need routine refrigerant topping up. A suspected loss needs appropriate leak investigation by qualified personnel.
The indoor unit brand or model, approximate age, symptoms, displayed fault code and safe access arrangements are useful. Describe what happens first rather than guessing which part has failed.
