Repair or Replace?

As long as you've got electronics and appliances in your home, you're inevitably going to be faced with a choice: Something breaks. Now what?

According to a 2005 Consumer Reports survey, Americans are repairing 16 percent fewer products—including high-cost items like television sets and refrigerators—than in 1997. The number of appliance-repairs shops has declined roughly 37 percent in 15 years while the number of electronics-repair shops has plummeted by 64 percent. So-called "e-waste"--computer monitors, televisions and other electronic waste—is the fastest growing portion of the U.S. waste stream. In 2005, electronics accounted for 2.63 million tons of waste—only 12.5 percent of which was recycled.

If you're lucky enough to find a repair shop, it may seem that the best environmental option would be to hang on to old appliances and electronics for as long as possible. Along with the environmental impact of new-product production, there's another concern: Many electronics contain heavy metals (such as lead and mercury), flame retardants and other toxic chemicals that can wash into waterways and pollute groundwater if sent to a landfill. But older products can be a big drain of household energy. "You need to consider buying a new product—which must be manufactured—or fixing your existing product, which may not be up to the latest energy standards," says Greg Keoleian, Ph.D., co-director of the Center for Sustainable Systems at the University of Michigan.

From a price perspective, if the cost to repair a household appliance is more than half the price of a new product, advances in energy efficiency will generally make buying a newer model the cheaper choice. Based on these numbers and considering today's more environmentally friendly technologies, here's a guide to when you should repair or replace.

Washers

* Replace all top loaders.

When Keoleian and his colleagues compared the average lifecycle of a washing machine (14 years) with the amount of water and emissions that could be saved by a newer model, they determined that even replacing a 2005 machine could have water-saving benefits. The reason: Water- and energy-saving technology continues to evolve as companies push beyond standards. It's most important to replace top loaders with Energy Star-labeled new front loaders as soon as possible; although they're generally more expensive, these models circulate clothes in a shallower pool of water, using less water and heat, and saving money in the long run. (Getting rid of a pre-1994 washer, for example, can save a family $110 a year on utility bills.) For models, see our Washing Machine Product Report.

Clothes Dryer

* Repair if possible, but line dry clothing whenever you can.

As long as your dryer has a moisture sensor (nearly all models in operation today should), it functions at about the same efficiency as current models, according to the American Council for an Energy-Efficient Economy. A dryer's average life cycle is about 13 years, so if it's possible to fix it during this time, try that first. When it is time to buy a new dryer, look for one with the sensor in the drum, as opposed to in the exhaust vent; it will shut off a little sooner and save slightly more energy. However, since dryers consume large amounts of energy, line drying or hanging your clothes on a rack is a better option. For dryers and drying racks, see Virtuous Cycles.

Refrigerators

* Replace all models manufactured before 2001.

New refrigerators consume 75 percent less energy than those produced in the late 1970s, and are even more efficient than models just six years old, Keoleian's research has found. The newest federal standards went into effect in 2001—so if you need to make repairs on an older fridge, it's worth getting a new one instead. When replacing your refrigerator, opt for a top-freezer configuration rather than a side-by-side, and make sure it's Energy Star-certified. A new refrigerator should then last you about 14 years. And resist the urge to hold on to your old fridge or give it away, since inefficient old models can cost over $100 a year to run. Most communities have specific requirements for disposing of refrigerators and other large appliances; visit www.earth911.org for information in your area. For models, see our Refrigerator Product Report.

Dishwasher

* Replace non-Energy Star models.

Newer, more efficient dishwashers use less hot water, have energy-efficient motors and use sensors to determine the length of the wash cycle—making Energy Star models 25 percent more efficient than the minimum federal standards. This can mean a savings of $25 a year if you replace a pre-1994 machine. When shopping for a new dishwasher, choose one with a "light wash" or "energy saving" cycle—and expect to hang onto it for about 9 years, suggests the National Association of Home Builders. And remember that handwashing dishes is an inefficient alternative, generally wasting more water than dishwashers. For models, see our Dishwasher Product Report.

Air conditioners

* Replace window units older than 10 years and central-air systems older than 10, but consider alternative cooling methods.

Upgrading your window units to a more efficient model can cut energy bills by an average of $14 a year, estimates the Energy Star program. The most efficient room air conditioners have higher-efficiency compressors, fan motors and heat-transfer surfaces than previous models. Central ACs are rated according to their seasonal energy efficiency ratio (SEER)—for which most 1992 to 2005 models score about a 10; older ACs have ratings of only 6 or 7. New minimum standards set in 2006 require current central-air units to have a SEER of at least 13. Because of the coolants used, old room-AC units need to be disposed of in hazardous waste facilities; old central units are usually disposed of by the contractor hired to install the new unit, but always ask ahead of time to ensure proper disposal.

Before you buy, however, consider alternatives such as ceiling fans, evaporative coolers (if you live in a dry climate), whole-house fans and landscaping or decorating changes, all of which can keep your home comfortable for a fraction of the cost (see Keep Your Cool With Less AC). For models, see our Air Conditioner Product Report.

Water heaters

* Replace all electric heaters, and any gas heaters older than 10 years.

If you have an electric heating system, you can achieve a 50 percent energy savings used by switching to a high-efficiency gas model. Gas heating systems can last for about 25 years but will operate for years at very low efficiency before they finally fail [but do they operate at low efficiency because of something that can be repaired?] ; if yours is more than 10 years old, it probably operates at less than 50 percent efficiency and deserves to be replaced. Consider a "demand," or tankless, system, in which water is circulated through a large coil and heated only when needed. Although EnergyStar doesn't certify these models, the government estimates that they can save between 45 and 60 percent of water heating energy and up to $1,800 a year when compared to standard, minimum-efficiency heaters.

Computers

* Repair as long as you can.

"The manufacture of brand new computer models uses more than four times the energy and resources it would take to extend the life of an older machine for another few years, says Sheila Davis, executive director of the Silicon Valley Toxics Coalition—so it's best to always repair it yours if possible. Memory can be added to slow computers (1-gig will run about $100 and you can install it yourself). But it's important to consider the repair process, says Davis: Name brand computers often have proprietary parts and need to be shipped back to the manufacturer—or sometimes even overseas—to be fixed. "White box" computers, that is, generic models without name brand parts, can easily be upgraded at local computer stores, but warranties for them can be tricky. They come without software, and finding technical support may be difficult. White box models are available online or at large computer chains.

If you prefer a name-brand item, choose one with a strong takeback program that will guarantee your computer won't end up in a landfill. Dell takes back all branded products for free; others accept new models or charge a small fee. Visit www.computertakeback.com/docUploads/Using_takeback_programsv7a.pdf for a comparison of most popular brands. As far as desktops versus laptops, it's a toss-up: "Even though laptops are smaller, they often have just as many chemicals to dispose of," says Davis. If you still have a large cathode-ray tube (CRT) monitor, replace it with a flat-panel liquid crystal display: A 15-inch LCD screen uses about 18 watts of energy, as opposed to about 200 for CRT's. For models, see our Computers Product Report.

Smaller electronics

* Replace, but recycle.

It's probably not financially practical to repair electronics such as printers, televisions, and digital cameras, but it's best to keep them out of landfills. Before ditching them, always consult the instruction manual and consider contacting the manufacturer; sometimes they'll provide repairs for a small fee. When they do need to be disposed of, visit www.greenerchoices.org for recycling options that won't put toxic chemicals back into the environment. Cell phones, for example, are often reprogrammed and donated to women facing domestic violence (as a 911 lifeline), and chains such as Best Buy and Staples often sponsor collection drives for other broken electronics (see also www.eco-cell.org). Apple will take back iPods (as well as cellphones), offering a 10 percent discount towards your next purchase.
