Frequently Asked Questions
Common questions about air conditioning installation and services in Sussex
How much does air conditioning installation cost in Sussex?
Air conditioning installation costs vary depending on the system type, number of units, and complexity of installation. For a single room split system, prices typically start from £1,599 including installation. We provide detailed, no-obligation quotes after assessing your space and needs.
How long does air conditioning installation take?
Installation timeframes vary by project scope. A standard single room split system typically takes 1 day to install. Multi-split systems serving 2–4 rooms usually take 1–2 days, while larger commercial installations may require 3–5 days or more.
Do I need planning permission for air conditioning in Sussex?
In most cases, domestic air conditioning installations don't require planning permission as they fall under permitted development. However, there are exceptions for listed buildings or conservation areas. We can advise on planning regulations specific to your property.
How energy efficient are modern air conditioning systems?
Modern air conditioning systems are highly energy efficient, with many units achieving A+++ energy ratings. The systems we install use inverter technology that can reduce energy consumption by up to 30–50% compared to older units.
