FAQs
Why should I choose an energy-efficient air-conditioning unit for my home or business in Lancing?
Modern A++, inverter-driven systems use up to 40 % less electricity than older fixed-speed models, so you’ll notice immediate savings on your utility bills. They also modulate output to match the exact cooling or heating load, giving steadier temperatures, lower noise and longer equipment life. With Lancing’s mix of coastal humidity and occasional heat waves, an efficient system keeps indoor conditions comfortable year-round while reducing your carbon footprint.
How much can I save on running costs by upgrading to a high-efficiency unit?
Actual savings depend on the size of the space, insulation levels and how you currently heat or cool, but most customers see their annual energy use drop by 25–50 %. For example, replacing a 10-year-old 12 kW unit with an A++ 8.5 kW inverter model can cut electricity consumption by about 1,500 kWh per year—roughly £450 at current rates. Because the new system also provides economical heating down to –15 °C, you can reduce reliance on electric radiators or expensive gas boilers in spring and autumn.
Do I need planning permission to install air conditioning in Lancing?
In most cases, no. Domestic heat-pump-type air conditioning is classed as a ‘permitted development’ in West Sussex, provided the external condenser is below 0.6 m³, mounted at ground level or on a rear wall, and sited at least 1 m from the property boundary. Commercial properties or installations in conservation areas may require an application, and any unit over 12 kW will need a noise assessment. We’ll survey your site and advise you before work begins.
How long will installation take and will it disrupt my routine?
A single-room split system typically takes one day; a multi-room or ducted heat-pump installation may require two to three days. Our engineers schedule work around your timetable, use dust sheets and cordless vacuum tools, and remove all packaging and old equipment for recycling. Power and water are disrupted for only a few minutes during commissioning, so you can usually stay in the property while we work.
What maintenance does an energy-efficient unit need to stay at peak performance?
Basic upkeep is straightforward: clean or replace indoor filters every one to three months, keep the outdoor unit clear of leaves and debris, and check that condensate drains are free-flowing. We recommend an annual professional service, which includes refrigerant pressure tests, deep cleaning of coils, electrical safety checks and energy-efficiency recalibration. Regular servicing protects your warranty, maintains top performance and can prevent up to 15 % energy loss caused by dirty coils.
Are there any incentives or finance options available for energy-efficient heating and cooling in West Sussex?
Yes. Domestic customers can spread the cost over up to 36 months at 0 % APR through our FCA-regulated finance partners. Businesses may claim the 100 % Annual Investment Allowance on qualifying heat pumps and VRF systems. You may also be eligible for the Boiler Upgrade Scheme (BUS), which pays £5,000 toward an air-source heat pump that replaces a fossil-fuel boiler. We handle all paperwork, including MCS certification, to secure funding on your behalf.
