Why Devon homes get uncomfortable
The coast keeps Devon mild, but mild cuts both ways. Along the seafront in Torquay and Paignton, warm spells arrive with sea air that makes bedrooms feel closer than the weather forecast suggests, and the converted Victorian villas and loft rooms that make up so much of the Riviera's housing hold that stickiness well into the night. Exeter's terraces around St Leonard's and Heavitree have the familiar problem of south-facing bays and attic conversions trapping afternoon heat. Plymouth is a mix — pre-war terraces alongside the post-war rebuild of the city centre, much of it with modest ventilation.
Inland is a different story. Cob and solid-wall building is common across mid and rural Devon, and thick walls are slow to warm — but once a hot week has soaked in, they hold that heat, and there's no cavity to insulate. A stuffy spell can linger after the weather breaks.
The flip side of a mild climate: a split system is a reversible air-to-air heat pump, so the same unit heats in winter as well as cooling in summer — genuinely useful in a damp Devon winter, especially for the room the radiators never quite reach.
Planning, wiring and older buildings
A lot of Devon's housing is protected, or simply old, so a few checks come before anyone drills a wall:
- Conservation areas and listed buildings are common — towns like Topsham and Totnes, and parts of Exeter and the seaside resorts. Check with your local council before an external unit goes up rather than assuming either way. Homes in or around Dartmoor National Park come under the park's own planning authority.
- Flats and leasehold conversions — including many of Torquay's divided villas — usually need the freeholder's consent for an outdoor unit.
- Older wiring is worth checking early. Some homes need electrical work before an installation can go ahead — our guide to whether your home electrics can handle air conditioning covers what an installer will look for.
On price, we'd rather point you at honest numbers than quote a figure that turns out wrong for your house — costs depend on the property, the walls and how many rooms you're doing. Our guide to air conditioning costs in the UK sets out realistic ranges. One thing to know upfront: air-to-air systems aren't covered by the Boiler Upgrade Scheme, which applies to air-to-water heat pumps only, so plan without counting on a grant.
Where Coolhouse is up to in Devon
Straight answer: we're not live in Devon yet. Our vetted installers currently cover Hertfordshire, and we're working on building the network out to counties like Devon. If you leave your details, we won't pretend otherwise — we'll tell you plainly where we've got to, and you'll be first in line when a vetted installer comes on board in your area.
