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!
Dollar
Dollar (population 2,877) is a small town with a population of 2,800 people in Clackmannanshire, Scotland. It is 12 miles East of Stirling. Dollar was when an address of Mary, Queen of Scots. Possible analyses are that Dollar is originated from Doilleir, an Irish and also Scots Gaelic acceptation dark and also dismal, or from various words in Pictish: 'Dol' (field) + 'Ar' (cultivatable) or Dol (valley) + Ar (high). Another derivation is from Dolar, 'haugh location' (cf Welsh dôl 'meadow'. This word was obtained from British or Pictish right into Scottish Gaelic as dail 'water-meadow, haugh'). John Everett-Heath, in acquires it as 'Place of the Water Meadow' from the Celtic dôl 'water field' and ar 'area'. A more theory, linked to Castle Campbell's different name of Castle Gloom, is that it stems from Scots-French "Doleur", meaning despair.
