Wall-mounted air conditioning in Plymstock
Where a home in Plymstock faces the street, the outdoor unit usually goes at the rear, out of sight. Coastal breezes help, but inland South West towns and glazed rooms still see uncomfortable peaks.
In a semi or terrace in Plymstock, the indoor unit often goes on a back bedroom wall with the outdoor unit on a bracket below. Plymstock sits around 2 miles from Plymouth, inside our Devon area. Postcode districts we cover here include PL9.

Planning and permissions
Since 29 May 2025, England's permitted development rules allow larger outdoor units (up to 1.5 m³) and no longer require a 1 m gap to the boundary, provided the MCS 020(a) noise check is met. Listed buildings and pitched-roof installs still need permission.
