BOSTON ( MainStreet) -- "Green" technology can turn the hot weather baking much of America this summer from a drag on your home's air-conditioning bill to a source of free solar energy -- if you know what improvements to make.
Sachs estimates homeowners can recoup the costs of carefully chosen energy improvements over five years -- and enjoy a much more comfortable indoor climate in the meantime.
"By bringing your home's energy systems under control, you'll get rid of drafts, kill a lot of equipment noise and eliminate rooms that are too hot or too cold," he says. "That's worth a lot right there."Here's a look at five high-tech moves the expert believes every homeowner should consider this summer to maximize their property's energy efficiency: Cost figures are estimates for a typical four-bedroom home and were provided by Complete Home Evaluation Services, a Maine energy-efficiency consultancy. Get a home energy audit
Cost: $200 to $750
Sachs recommends getting a "Home Energy Rating System" review or other comprehensive audit of your property's fuel efficiency before even thinking about installing a solar panel or new air conditioner. "Instead of just blindly throwing money at energy efficiency, you want to invest in a consultant with the right tools and get the right 'road map' of what to do," he says. Home-energy audits typically take around a half-day and involve checking your home's heating and cooling systems, as well as using high-tech infrared heat detectors and negative-air-pressure machines to find gaps in your property's insulation. Audits typically cost a few hundred dollars, but your local utility or state energy commission will sometimes offer them for free or at a reduced cost. Fix your home's "envelope"
Cost: $4,000 to $5,500
Once you've done an energy audit, you should fix any gaps the review has uncovered in your home's "envelope" -- the insulation that separates heated or cooled living spaces from unheated attics or the outdoors.
