Modern inverter systems cool in summer and can also run as an efficient air-to-air heat pump in winter. Who it's for Homeowners with rooms that overheat, such as loft conversions, south-facing bedrooms, conservatories and garden offices. It also suits home workers and small businesses that need a comfortable, steady temperature. When you need it Ideally before summer arrives, when installers get booked up. It is also worth doing during a loft conversion, extension or refurbishment, when pipe runs can be hidden easily. Why professional matters UK summers are getting hotter, and many homes are built to hold heat. A properly sized inverter system cools a room in minutes, runs quietly and uses far less energy than portable units. What it costs to delay ## The real consequences of putting it off Air conditioning only works well when it is sized and fitted properly. Here is what goes wrong when corners are cut: ### Wrong size unit An undersized unit runs flat out without cooling the room. An oversized one keeps switching on and off, which wastes energy and wears it out. ### Poor positioning If the indoor unit blows straight onto a bed or desk, the room feels uncomfortable. A badly placed outdoor unit can annoy neighbours. ### Messy pipework Untidy trunking and badly sealed wall cores look poor and can let in draughts and damp. ### Common mistakes we fix Relying on portable unitsPortable units are noisy and inefficient, and they vent heat through a window gap. They are a stop-gap, not a fix. Choosing on price aloneCheaper non-inverter units cost more to run and are usually louder.

The Engineering Detail ## Under the bonnet What you should know before choosing a system: ### Split vs multi-split A single split has one indoor unit and one outdoor unit. A multi-split runs two to five indoor units from a single outdoor unit, which is ideal when you want to cool several rooms. ### Sizing We size each unit to the room's volume, glazing and sun exposure, so it is neither underpowered nor oversized. ### Outdoor unit placement We place outdoor units on brackets or a ground plinth, away from boundaries where possible, to keep noise down and allow easy servicing. ### Maintenance Clean the filters regularly and have the system serviced every year. This keeps it efficient and protects the manufacturer warranty.
