Can air conditioning be used for heating as well as cooling?

Yes. Many modern air conditioning systems can provide both cooling and heating, making them useful throughout the year, not just during warmer months.

How do I know what size air conditioning unit I need?

The correct unit size depends on the room size, layout, insulation, window positions and how the space is used. We carry out a site survey and recommend a suitable system based on your property.

Do air conditioning systems need servicing?

Yes. Regular servicing helps keep the system running efficiently, improves performance and can help prevent faults. It also keeps filters, coils and key components clean and working properly.

How long does air conditioning installation take?

Most standard single-room installations can usually be completed within a day, depending on the property, system type and installation requirements. Larger or multi-room systems may take longer.
