Three jobs to consider
Cooling controls temperature. Ventilation supplies and removes air. Filtration captures certain particles as air passes through a filter. A system may combine some of these functions, but a wall-mounted AC should not be assumed to provide all three. Check what your selected model and building system actually do.
Look for a fresh-air route
The US EPA notes that most home heating and cooling systems do not mechanically bring outdoor air inside. Air may enter through openings, natural ventilation or a designed mechanical system. The appropriate arrangement depends on the building and outdoor conditions.
Start with the room’s use
Tell us how many people use your space, how long it is occupied and whether it has windows or extraction. Mention persistent odours or stuffiness so we can discuss what needs checking alongside your cooling and ventilation requirements.
Discuss the whole air system
- Where does outdoor air enter, and where does indoor air leave?
- Are existing vents or grilles blocked?
- Who looks after filters, extraction and ventilation equipment?
- What maintenance access will a new system need?
Plan maintenance alongside equipment
The EPA recommends keeping spaces clean and dry and reporting ventilation concerns to the people responsible for the building. HydroKleen can help review your AC requirements and discuss ventilation products where appropriate. For a wider building issue, the design and operating arrangements need assessment as well as the equipment.
