The Phoenix, Arizona metro area has a well earned reputation for having some of the hottest days and highest temperatures in the country. Such extremely high temperatures can force many Phoenicians to run their air conditioners all day and night. This of course can take a toll on your AC unit, especially if your central air conditioner is just 10+ years old. Older AC units also tend to use much more electricity because they generally run at or below 10 SEER, or Seasonal Energy Efficiency Ratio….this is the amount of energy needed to provide an adequate amount of cooling. Prior to 2006, 10 SEER was the standard, however, since then, 13 SEER became the minimum allowed by federal law. This means that your electricity bill could be as much as 30% lower with an AC unit that has a 13 SEER rating. If you live in the Valley and are considering whether you need to replace your old central air conditioning unit with a new more energy efficient one, contact a professional HVAC company such as Hendel’s Air Conditioning of Chandler, Arizona. Hendel’s is located at 3434 N. Arizona Ave., Chandler AZ 85225 or you can call them at 480-813-1700.
