Most air conditioning units will need yearly maintenance. This will involve a full service and cleaning of filters. In very dusty areas units may need more frequent maintenance. Regular servicing will extend the life of an air conditioning unit. Keep a record of when this is done so you know when to contact someone!
Isle Of Coll
Coll is an island situated west of the Isle of Mull in the Inner Hebrides of Scotland. Coll is known for its sandy beaches, which rise to create huge dune, for its corncrakes, as well as for Breacachadh Castle. It remains in the council location of Argyll and Bute. Coll is about 13 miles (20 kilometres) long by 3 miles (5 kilometres) large and has a population of around 150. Coll's sandy beaches rise to create huge dune. The acme on Coll is Ben Hogh in the mid west of the island, a ridge with two tops running NW/SE, which climbs at first to a height of 104 metres (341 feet) with a triangulation column, and also to 106 metres (348 feet) 450 metres (492 yd) to the southeast. In the 2011 census, the island's population was recorded as 195, standing for an increase over the previous years of virtually 19%.
