Heat load surveys and system design in Prescot
For self-builds and extensions in Prescot, a standalone design pack can go straight to your builder. Damp North West weather makes the dehumidifying mode of a modern split system genuinely useful for much of the year.
No two rooms in Prescot gain or lose heat in quite the same way, which is exactly why rooms are measured before sizing. Prescot is about 7 miles from Liverpool and falls within our Merseyside coverage. Coverage includes L34.
