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 £1,200 including installation. Multi-split systems for several rooms start from £3,000, while commercial VRF/VRV systems have a broader price range based on your specific requirements. 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. We always provide a specific timeframe for your project during the quotation process and work efficiently to minimize disruption.
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, particularly for listed buildings, conservation areas, or if the external unit would face a highway. Commercial installations may have different requirements. We can advise on planning regulations specific to your property and location in Sussex and handle any necessary permissions as part of our service.
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 adjusts power according to the required temperature rather than simply turning on and off. This can reduce energy consumption by up to 30-50% compared to older non-inverter units. Many systems also offer heat pump functionality, providing efficient heating in winter as well as cooling in summer.
How often should air conditioning be serviced in Sussex?
For optimal performance and longevity, we recommend servicing your air conditioning system at least once a year. In coastal areas of Sussex where salt air can accelerate wear, or in commercial environments with heavy usage, bi-annual servicing may be beneficial. Regular maintenance ensures energy efficiency, prevents costly breakdowns, and maintains healthy air quality. We offer comprehensive maintenance plans to keep your system running perfectly year-round.
