Domestic units that are not in constant use and are used for cooling only generally require one service per year. Units that are in offices should be maintained at least twice per year to keep them running at their optimum level. For server rooms, we recommend at least three service visits per annum. For areas with high levels of pollution or contaminants in the air such as kitchens, hairdressers or workshops, additional service visits are carried out.

There are various reasons why your system is leaking water.

The condensate that is produced in the coils on the indoor part of your system should fall into a drip tray which is either drained away by gravity or pumped outside.

If excess water is finding its way down your wall then it’s more than safe to assume that much or all of the condensate is not being drained away.

Sometimes the drain hole might clog up with dirt, so the water obviously finds the easiest route to drain away which can’t be anything other than down your wall! However, if the condensate is being drained away with help from a pump, then there is every probability that the pump may have failed and this will obviously need replacing quickly. So often we find that the coils in the system have been so caked up with dirt that it has ended up blocking the unit drainage system.

A leak can be caused by something as simple as a dislodged drainage pipe, making the water drain upwards, which, of course, eventually flows back into the unit and down your wall. In this case, it’s a simple matter of correcting the angle of the drainage pipe.

Finally, and in more serious cases, should the system have leaked a large quantity of refrigerant, this will cause the coils on the indoor unit to “ice up” which will also result in leakage when the ice melts. If you do see ice on the coils, it is vital to switch the unit off immediately and call your air conditioning engineer.

Many of these problems can be avoided by regularly maintaining your unit.

To install an air conditioner, you must be a qualified air conditioning engineer with an F-Gas certificate. We are often called out to sites to fix units that have been incorrectly installed. DIY installations or even installations by qualified builders without the necessary expertise in air conditioning invariably end up costing much more in the long run with wasted time and materials.

Regular servicing and maintenance keep your unit running at maximum efficiency, significantly extends the lifetime of a unit and reduces operating costs. In addition, routine maintenance will ensure that the unit qualifies for the full warranty of up to ten years rather than just the standard manufacturer’s one year warranty.

Mitsubishi Electric is usually acknowledged to be one of the market leaders and comes with a warranty of up to ten years. However, Gree air conditioners provide an equivalent level of reliability at a lower price.

An air conditioning unit is designed only to cool the room for which it has been specified; leaving inter-leading doors or windows open will reduce its effectiveness.
