Yes, all portable air conditioners must vent hot air out of the room. This is usually done through a window using a supplied venting kit. We set this up as part of our service.

Only if there is another way to vent hot air, such as a door or wall vent. A room with no external access is not suitable for most portable AC units without proper ventilation.

Portable units do produce more sound than split systems. Most range between 50 to 65 decibels, similar to a fan or quiet conversation. We can recommend quieter models if noise is a concern.

Many units have a self-evaporating function, so you rarely need to empty water manually. In high humidity or older models, the tank may need to be emptied every few hours or daily.

Some models include a built-in heat pump, allowing them to provide heating as well as cooling. Ask us about dual-function portable units when requesting your quote.

Yes. All our portable units come on wheels and are lightweight enough to move between rooms. Just ensure there’s a venting option in each room for proper use.

They are less efficient than fixed systems but still cost-effective for short-term or room-specific use. Units with A or A+ energy ratings and eco modes help reduce running costs.

Some high-output models are suitable for equipment rooms, but it depends on the size and heat load. We can advise based on your technical setup.

It depends on the size of your room and insulation. As a rough guide:
• Up to 20m² = 7,000 BTU
• 20–30m² = 9,000–12,000 BTU
• Over 30m² = 14,000 BTU+
We’ll confirm the right size during your consultation.

Yes, most units have sleep or timer modes to run quietly and efficiently at night. We’ll show you how to adjust settings during setup.
