Upgrade to an efficient central air conditioner

Why? You could save up to 50% on cooling costs by switching to a newer, more efficient air conditioner. When you decide to replace your old air conditioner, investing in an efficient, ENERGY STAR® certified unit will dramatically lower your cooling costs.
What to look for:
  • High energy efficiency ratings. A Seasonal Energy Efficiency Ratio (SEER) of 15 is the industry standard, but systems with higher SEERs cost less to run.
  • ENERGY STAR certified models. These are the most efficient air conditioners and cost the least over their lifetimes.
  • The yellow EnergyGuide label. This helps you compare specific models.

What to look for in a qualified contractor: Many problems that occur with a new air conditioner may be caused by improper sizing or installation. To choose the right size unit for your home, your contractor should consult current industry standards. Sizing should be determined by the square footage of your home or the size of your current unit. For advice on finding and choosing a contractor, visit www.energystar.gov.

Good to know: Before you replace your system, think about air sealing and improving insulation in your home. This will reduce your required cooling load and help any air conditioner run more efficiently.
