Air conditioners have a sometimes bewildering array of options that are designed to increase the unit’s efficiency and performance. Here are some of the more important features to look for when you’re thinking about an upgrade.
- Efficiency: High-efficiency air conditioners provide excellent cooling while keeping your monthly utility bills low. Depending on the type of air conditioner you have now, a high-efficiency upgrade could cut your cooling bills almost in half. Look for models with an Energy Star label and a Seasonal Energy Efficiency Ratio of 13 or higher.
- Two-stages compressor: A unit with a two-stage compressor runs at a lower speed most of the time, ramping up only when you need maximum cooling. This feature can cut your cooling costs by more than 10 percent. And because your unit won’t be working more than it should, it will likely last longer than a unit that runs at top speed all of the time.
- Sound dampening: Look for insulation and vibration isolation. If noise is a particular concern for you, check out the decibel ratings on each unit you’re considering.
- Warranty: The compressor should have a 10-year warranty, and the parts should have a five-year warranty. Some units have better warranties. Also ask your contractor about his service plan — or plans — for air conditioners.
While you’re meeting with your contractor, ask him how he will size your unit. A unit that’s too small for your home won’t provide enough cooling and will work harder than it should. On the other hand, a unit that’s oversized will cycle on and off too frequently, providing insufficient dehumidification and poor home comfort. Make sure your contractor uses Manual J, the industry standard, when he sizes your new unit.
As a plus, your new unit will use a more environmentally friendly refrigerant that is replacing the R-22 refrigerant commonly used in older units. Along with improved efficiency, you’ll have the satisfaction of knowing that your new air conditioner is easier on the Earth’s ozone layer, and you’ve made your carbon footprint smaller.
