Air Conditioning for Loft Conversions
Loft conversions present one of the most extreme overheating challenges in domestic buildings. Heat rises — and in summer, a loft bedroom or office can reach temperatures 8–12°C higher than the ground floor. Opening a Velux window provides minimal relief. Air conditioning is the only reliable solution, and Forge Air specialises in loft installations.
Key considerations for air conditioning for loft conversions
Extreme heat gain
Lofts receive direct sun on the roof all day. We specify systems with sufficient capacity to overcome this — typically 30–40% more than a comparable ground-floor room.
Sloped ceilings
Unit positioning in lofts with sloped ceilings requires expertise. We identify the optimal location for both mounting practicality and airflow effectiveness.
Pipe routing to outdoor unit
In a loft installation, refrigerant pipes typically run down through the building to an outdoor unit at ground or first floor level. We plan this route carefully to minimise disruption.
Noise
Loft bedrooms benefit most from the quietest available systems. We recommend units with a sleep mode operating at 19–22dB.
Why air conditioning works here
- Solves overheating that no other solution can reliably address
- Transforms an unusable summer bedroom into a comfortable space
- Also heats efficiently in winter — lofts lose heat rapidly
- Sleep-mode operation as low as 19dB
- Significantly increases the usability of your loft investment
- Can be installed in occupied lofts with minimal disruption
System type
Loft installations are single-split systems. The outdoor unit is typically mounted at first floor or ground floor level, with pipes routed carefully through the building. We always survey loft installations before quoting.

My loft bedroom is unbearable in summer — what can I do?
Air conditioning is the most effective solution available. Insulation and ventilation help marginally, but only a properly sized air conditioning system can reliably maintain a comfortable loft temperature in British summer heat.
How do you route pipes in a loft conversion?
We survey the best route at the free home survey. Typically pipes run vertically down through the building, often concealed within an airing cupboard, wardrobe, or purpose-built boxing.
Is there a cassette option for a loft?
Ceiling cassette units are possible where ceiling height and joists allow. They offer a more discreet installation than a wall-mounted unit in a loft room. We'll advise at survey.
