What's the best window AC for your buck?

SAN ANTONIO – Just in time for the long, hot dog days of summer, Consumer Reports is out with recommendations for some of the top window air conditioners.
 
A window unit can be a cool solution to make a room more livable. 
 
Consumer Reports put several to a tough test: Cooling a room that's 90 degrees, with nearly 60 percent humidity, down to a much more comfortable 75 degrees.
 
The best, Consumer Reports said, can cool a room within 15 minutes, keep the temperature consistent and not break the bank. 
 
Here are some top models, according to their tests:
 

• For a small room between 100 and 300 square feet: Amana model AMAPO61BW for about $200.
•  
• For a medium room between 250 and 400 square feet: Kenmore Elite model 77087 for about $310.
•  
• For a large room between 350 and 650 square feet: LG model LW1216ER for about $350.

 
To keep an air conditioner cooling efficiently, clean the filter at least once a month during the summer.
