Where an older house meets a glazed extension, first identify which room is uncomfortable and at what time of day. Check wall construction and routes for pipes and drainage before settling on an indoor unit position.
Follow the temperature difference across the extension
Compare the original room and the glazed addition at the time overheating is worst. Note whether the connecting opening is full width or a conventional doorway. The cooling design should address those different loads and airflow paths instead of selecting a unit that merely fits neatly on the nearest external wall.
Check the wall and drainage route together
A proposed pipe route through an older wall may need a different approach from a newer extension wall. Show retained finishes and any concealed services that are known. Agree how condensate will leave the room and which surfaces need making good, so an attractive indoor position does not depend on an unresolved route through the building.
What the service involves
Start with the rooms that overheat. A survey considers glazing, occupancy, equipment, shading and airflow to specify quiet summer cooling, with reverse-cycle heating available when needed.
- Survey cooling demand and agree indoor and outdoor positions.
- Confirm capacity, electrical provision, pipework and condensate routes in the quotation.
- Install, commission and demonstrate the controls, with maintenance access built in.

Questions about air conditioning installation in Christchurch
Will opening the extension doors spread cooling through the house?
Some air may move, but reliable comfort in other rooms cannot be assumed. Their heat gains and the available air path need assessment before treating one extension unit as a whole-house solution.
Can the pipe route be decided on installation day?
It is better to resolve the main route during the survey and quotation. Late decisions can affect drainage, appearance and the amount of making good required.
