1930s semi in Leeds — air-to-air across four rooms
Leeds, LS8
A family in a 1930s semi wanted cooler bedrooms in summer and warmth in a cold home office. We fitted a four-room air-to-air system with independent control for each space.

System: One outdoor unit, four wall-mounted indoor units
A typical inter-war semi: warm bedrooms under the roof in summer, a rear home office the central heating never reached, and a family working around both problems with fans and a plug-in heater.
We assessed the four rooms from photos and a short video, confirmed capacities, and agreed the outdoor unit position on the side return where it’s out of sight and away from bedroom windows. Installation took two days. Each room has its own thermostat and remote, so nothing runs unless it’s wanted.
The result
The bedrooms are usable on hot nights and the office is comfortable to work in year round. The owners run only the rooms they are using, when they are using them.
“They were clear about what it would and would not do. Two rooms we thought we needed, we did not — and they said so.”
