Why Swansea homes get uncomfortable
Swansea doesn't do scorching summers often — the climate is mild, damp and maritime. But the housing stock does a lot of the work. The Victorian and Edwardian terraces of Uplands, Brynmill and St Thomas were built to hold heat, and once a warm spell arrives they hold it stubbornly, especially in loft conversions and rear extensions. Newer flats around SA1 and the marina have the opposite problem: big glazing, sealed windows and nowhere for the heat to go. Add the muggy air that rolls in off Swansea Bay and even a modestly warm day can feel heavy indoors.
The stronger argument here, though, is winter. A modern split system is a reversible air-to-air heat pump: the same unit that cools in July heats in January, and it puts out several units of heat for each unit of electricity it uses. In a mild coastal climate like Swansea's, that efficiency holds up well through most of the winter — often a better reason to fit one than the handful of hot weeks each year.
Salt air, old wiring and permissions
Living near the coast — Mumbles, the seafront terraces, anywhere with a westerly view — means salt-laden air blowing over the outdoor unit. It isn't a dealbreaker, but it is worth choosing kit with anti-corrosion protection and siting the unit somewhere sheltered; a good installer will factor this in from the start. A few other things to check before you get quotes:
- Prices vary a lot with the size of the system and the state of the house, so treat any figure quoted sight-unseen with suspicion. Our guide to air conditioning costs in the UK explains what actually drives the price.
- Older terraces often need an electrical check first, and some need a consumer unit upgrade before anything else. Our guide on whether your electrics can handle it covers what to look for.
- If you're in a conservation area — parts of Mumbles, or out towards Gower — check with the council before fixing anything to an outside wall. Flats and leasehold homes usually need the freeholder's consent too.
- Air-to-air systems aren't covered by the Boiler Upgrade Scheme, which only funds air-to-water heat pumps, so don't budget around a grant.
Where Coolhouse is up to in Swansea
Honestly: we're not here yet. Our vetted installers are currently in Hertfordshire, and Swansea is one of the areas where we want to build the network next. If you leave your details through our estimate tool, we'll tell you straight where we've got to and get in touch as local installers come on board. We'd rather be upfront now and earn the job when we can actually do it well.
