No Outside Box air conditioning
What a no outside box system looks like in a room, where it fits best and what we need to install it.
Strengths
Why customers choose this format.
- No outdoor unit — useful where one isn't permitted
Limitations
Worth knowing before you decide.
- Two wall cores needed
- Lower capacity and efficiency than a split
Installation prerequisites
An external wall for two vent cores and permission for external grilles.
Maintenance access
Filters and coils need regular cleaning, so we plan for safe access to the indoor unit from day one.
Estimate first, survey when needed
Our online estimate is free and indicative. Where a design needs confirming on site, we offer a paid technical survey at £395, credited in full against your installation if you go ahead.
