If your air conditioner is over 30 years old, it needs replacing. Modern air conditioners and central Air Conditioning Sparks are far more energy efficient than older models. A new air conditioner will wind up paying for itself in reduced energy bills.

Make Your Home Cooler

Before you start shopping for a new air conditioner, check your home to see if you can make it more energy efficient and reduce your need to keep an air conditioner cranked to the max. Check for gaps in your windows and under doors where cool air can escape. How old is the insulation in your home? New insulation not only helps keep your home warmer in the winter, but cooler in the summer. Also make sure your windows have shades on them.

Get the Right Size

According to the Weather Channel, bigger is not better when it comes to air conditioners. Getting an air conditioner that is too large for your home is just as expensive in long-term costs as getting one that is too small for your home. Check the Air Conditioner Contractors of America’s website for a free calculator to determine just how large a unit you need. Size is measured by British Thermal Units or BTUs – even for American made air conditioners.

Energy Efficiency Ratio

Only select air conditioner units with a good energy efficiency ratio (EER) of 8.0 or more. Avoid used or air conditioners made before 1990 because they are not federally required to be energy efficient. If you are looking for an air conditioner to cool just one room and not a whole floor or home, the EER should be at least 10.0. Ratings for central air systems are called the seasonal energy efficiency ratio or SEER. Central air conditioning systems should have a rating of 10.0 or more.

Don’t Be Blinded By the Price Tag

Getting an air conditioner that fits your home is much better than getting the cheapest possible air conditioner. Choose a brand name that your local HVAC contractor is comfortable installing and repairing. Ask the contractor if the model for sale is still being made. If not, then getting replacement parts for it may be difficult.
