Keep Your Cool: Air Conditioning 101

It's hot and it looks like temps are going to continue staying on the upper end of the thermometer for awhile. Using your air conditioner effectively, balancing comfortable temperature with energy use and effectiveness can be daunting, especially for those still wondering what type of AC unit is best for their room (size vs. power). We take a look at a few tips on how to beat the heat and discuss the different type of units worth considering...How To Use Your Air Conditioner Most Effectively
  1. Keep your thermostat between above 72º and below 82º to conserve energy. Setting the thermostat to 56º does not make your AC work faster or harder to cool you down, and is a waste of energy.
  2. Purchase a machine that is the right size for the space you want to cool. The bigger machine is not always the best. EnergyStar has this helpful chart for picking out a properly sized AC unit.
  3. Check filters monthly, replace when necessary to keep air flow at fullest.
  4. Check the coils of your indoor/outdoor unit, because they attract dust, and dust will lead to poor performance.
  5. Close off the rooms you are not using and close their ducts. The less room you have to cool, the better.
  6. Avoid using a humidifier while the AC is running. This just makes the AC work harder.
  7. Keep your thermostat away from high-energy appliances like TVs or computers, because the thermostat will pick up on their heat reading and run longer than necessary.
  8. if you're in the mood for some DIY, seal up all of the air leaks around the house, since this is a big waste of AC/heating energy in summer and winter.
