Check simple restrictions safely
Confirm the selected fan setting and that the intake and outlet are not blocked by curtains, furniture or stored items. Compare the airflow at different fan speeds after the system has had time to respond.
Inspect only filters intended for homeowner access and follow the model instructions for cleaning and refitting them. Operating without the correct filters or reaching beyond the user-accessible area can damage equipment and expose moving or electrical parts.
Why airflow may remain weak
Internal dirt, a fan problem, icing, sensor or control issues, closed grilles on a ducted system or an unsuitable installation can all affect delivery. If only one area is weak, air distribution or a local restriction may be relevant.
Low airflow can also accompany poor cooling, water leakage or ice. Treat those linked symptoms as useful evidence rather than separate problems, and avoid repeatedly running an iced or leaking unit.
What servicing and fault finding cover
An engineer can inspect cleanliness and filters, assess fan operation, check temperatures and look for signs of icing, drainage or control faults. The correct remedy depends on measurements and access, not a universal cleaning product.
Top Local can service and investigate split systems across Kent. Tell us which unit is affected, whether the fan sound has changed and when the filters were last checked or serviced.
