Tips for improving air conditioner efficiency

Summer is (nearly) upon us! After a wet, snowy, and cold winter — polar vortex, anyone? — a lot of people are welcoming warmer weather.

But the heat can also bring some high utility bills, as we crank air conditioners. So it's a good idea, whether for your wallet or for the environment, to consider tips for making your air conditioner work more efficiently.

First, check the seals. Check around window units to make sure they are sealed and that extra heat isn't getting into the house in the first place. Check also that your attic is properly insulated, which does just as much good in the summer as it can in the winter. Insulation prevents attic heat from leaking into your home and cool air from escaping.

Use blinds to keep the sun from baking your house's interior and consider architectural details that can further enhance the shade — and cooling effects. These include awnings or things like pergolas.

Keep your filter clean so the unit can operate better and keep vents clear. And consider ceiling fans to better circulate the air. If you have central air, make sure the ducts are checked regularly; not only do they accumulate allergens, but they work harder when they get clogged and dirty.

With air conditioning being more commonplace and less of a luxury, it's still important to remember that there is a lot we can do to maximize its effectiveness. In the end, both you and your bank account will feel more comfortable.
