Excerpt from This Old House Magazine article on “Air Conditioners Really are Getting Better” by Max Alexander
All in the Sizing
No matter how efficient your air conditioner is, it needs to be sized correctly for maximum comfort and minimum energy expense. The key is proper balance between the condenser, where the refrigerant is pressurized and cooled, and the evaporator, where indoor air is cooled and dehumidified before being circulated through the house’s ductwork by the air handler.
Condensers are sized by the refrigeration ton, or “ton” for short. That’s the amount of refrigeration needed to freeze one ton of water in 24 hours — 12,000 Btus per hour. As a general rule, it takes a ton of air-conditioning to cool 1,000 square feet of well-insulated space. When recommending size, a savvy air-conditioning contractor will take into account the home’s layout, insulation levels, air leakage, sun exposure, and general climate.
Undersizing a system can overwork the condenser and clog it with frost, which shuts the system down (for a time). But according to Richard Trethewey, This Old House’s plumbing, heating, and cooling expert, oversizing is the more common problem because contractors tend to jack up the tonnage in hopes of avoiding future complaints. “More is not better,” Richard warns. The house cools down so quickly that the thermostat shuts off the air handler before it has a chance to fully circulate and dehumidify the inside air. “Your house ends up feeling cold and clammy,” he says. His advice: Tell your contractor that you intend to keep the summer thermostat at 75 degrees — perfectly comfortable if the inside air has been sufficiently dehumidified.
Richard also recommends investing in a two-stage compressor, which works at full power only on the hottest days. The rest of the time, it doesn’t compress (and, by extension, cool) the refrigerant as much, so the air handler operates longer and has more time to squeeze humidity out of the indoor air. “You save energy and you’re more comfortable,” he says. “How can you beat that?”
Still, before you run out and replace your old system with a new and improved one, do some homework. The amount you should invest depends on how many days you’re likely to run it and your cost of electricity. “You don’t want to spend $2,000 for a system that saves you $100 a year,” Richard says, especially since condensers last only about 15 years. And when it’s time for an upgrade, make sure to replace the evaporator at the same time. If you try mixing old and new components, you’ll probably end up with a ruined compressor and no AC when you need it most. And that’s definitely not cool.

Air conditioning your home makes up approximately 44% of your monthly utility bill, according to the U.S. Department of Energy. Here’s some ideas on how to reduce those costs during the summer time:
1) Plant leafy trees that will grow at least 15 feet around your home’s exterior to stop the sun from reaching inside. If the trees or shrubs shade your air conditioner, you could boost your AC’s efficiency by up to 10%.
2) Installing solar screens or mesh-like window screens can result in intercepting up to 70 % of solar energy before it gets into your house
3) Lower your air conditioners thermostat setting to 78 degrees Fahrenheit when you’re at home. But let that number rise to a warmer temperature at night or when you’re away from home. This trick will save you 5-15% percent on your air-conditioning bills.
4) Set you AC fan speed on high, except on very humid days where you should set the speed on low. The slower air movement through the air-condition unit removes moisture from the air and improves comfort in your home.
5) Use fans to circulate air inside the house while you are at home.
6) Skip the stove-top boiling and oven baking; summer is for grilling and keeping the kitchen cool!
7) Make sure your AC unit is running efficiently by keeping the filter clean to allow for good air movement and keep the unit level so the condensation drains properly
8) Replace your older air conditioner with a newer unit and you could cut your energy costs in half.
9) Call Family Air to for an air conditioner check and make sure everything is running properly!

Many people don’t realize the importance of maintaining a clean filter in there heater and ac units. Once your filter becomes clogged it lowers the air flow that you feel throughout your home. It as well makes your system work harder to maintain the temperature that is most comfortable for you. When your system has to work harder, that means your electric bill rises. There have been cases where a filter can get so clogged the system malfunctions and starts a house fire. So why not take the extra time to change your filter once a month. We recommend if you have multiple indoor pets to check it twice a week and give it a shake outside. You will notice you have better air flow and a more efficient working system. If you have any questions give Family Air LLC a call where “Your Comfort Is Our Responsibility”.
