Clean the Filters
Summer is the time when all sorts of things will get caught in your air conditioner’s filter. When the filter is blocked by debris, the flow of air will be reduced substantially and thus lower the unit’s cooling ability. Have a trusted Edmonton air conditioning contractor like one from Capital Plumbing clean your filters regularly, or replace them if need be.
Plant a Tree
While this might not exactly be a “simple solution”, it does help cool your home significantly. If you do decide to plan a tree, try to plant it so that the shade it produces during the early afternoon covers the condenser of your unit. This way, it keeps the condenser cool, resulting in a more efficient and longer-lasting unit.
