How Does Air Conditioning Work for Heating and Cooling?
A modern air conditioning unit is essentially a heat pump. In summer it moves heat from inside your room to the outside, cooling the space. In winter, it reverses the process, drawing heat from outside and pumping it indoors.
This makes air conditioning remarkably efficient. For every 1 kW of electricity a heat-pump unit uses, it can deliver 3 to 5 kW of heating or cooling energy. Compared with a plug-in electric heater (which delivers just 1 kW of heat per 1 kW of electricity), air conditioning can cut your running costs significantly for the rooms where it is installed.
It is worth noting that air conditioning is not a replacement for your central heating system in most UK homes, but it is an excellent supplement, particularly for rooms that are hard to heat: home offices, conservatories, extensions and bedrooms where you want precise temperature control.

FAQs
Frequently Asked Questions
We install and service air conditioning systems across Norwich, Hethersett, Wymondham, Cringleford, Costessey, Attleborough, Long Stratton and surrounding areas in Norfolk. For commercial projects, we cover the whole of Norfolk and parts of Suffolk.
How much does air conditioning cost to install?ShowHide
Most domestic single-room (single-split) installations start from around £1,800 to £2,500 including the unit, fitting and certification. The final price depends on the system size, the number of rooms, pipe runs and any electrical work needed. We always provide a clear written fixed quote after a free survey, so there are no surprises.
Is air conditioning expensive to run?ShowHide
No. Because a modern unit is a heat pump, it delivers three to five times more heating or cooling energy than the electricity it uses, making it very efficient. Running costs depend on how often you use it and your electricity tariff, but cooling a typical room costs only a few pence per hour.
Do I need planning permission for air conditioning?ShowHide
In most cases no. For the majority of houses, air conditioning falls under permitted development provided the outdoor unit is sited sensibly and within size limits. Listed buildings, flats and conservation areas can have additional restrictions, and we will advise you on this during the survey.
How noisy is a modern air conditioning unit?ShowHide
Modern systems are very quiet. Indoor units typically run at around 19 to 30 decibels on low fan speed, quieter than a library, and outdoor units are designed to keep noise to a minimum. We position both units carefully to keep any sound well away from living spaces and neighbours.
Can air conditioning help with allergies and air quality?ShowHide
Yes. Most systems include washable filters that capture dust, pollen and other airborne particles as they circulate the air, and many offer additional filtration options. Keeping the filters clean with regular servicing helps maintain healthier, fresher air indoors.
What maintenance does air conditioning need?ShowHide
Very little day to day, beyond rinsing the indoor filters every few weeks. We recommend an annual service to clean the system, check refrigerant levels and keep it running efficiently. Regular servicing also protects your manufacturer's warranty and extends the lifespan of the system.
Can you install air conditioning in a garden room or garden office?ShowHide
Absolutely. Garden rooms and garden offices are one of our most common installation settings. They often overheat in summer and can be difficult to heat in winter. A compact wall-mounted air conditioning unit solves both problems in one.
