Conservatory air conditioning across Northamptonshire
In Northampton, the indoor unit usually goes on the original house wall inside the conservatory. Conservatories and orangeries in Northampton can swing from too hot in July to too cold in January. East Midlands summers bring dry, sunny spells, so glazing and orientation matter most when sizing a unit.
