When Are Energy Audits Really Needed?

energy auditEnergy audits help you root out inefficiencies in your home so you can enjoy greater comfort for less money. While you might think little inefficiencies don’t matter much in the mild Los Angeles area climate, acting on the information you get from an energy audit can cut your heating and cooling bills by 10 to 30 percent.

Track Down Wasteful Leaks

Even if you’ve applied caulk and installed weathersealing to seal the air leaks around your home, chances are you’ve missed many smaller leaks. The average home has so many air leaks it’s like leaving an average-sized window open all year. Even if you cut that in half, that’s still a lot of unwanted air loss wasting your cooled and heated air. What’s more, most air leaks develop around the floors, walls, and ceilings, where they’re hard to find without special equipment.

During an energy audit, your technician will perform a blower door test using a large fan set up in an exterior doorway. This depressurizes the house, temporarily exaggerating air leaks so they’re easy to find. Many energy audits also include a Duct Blaster test, which measures air duct leaks. Leaks can waste up to 30 percent of the air traveling through the ducts.

Find Weak Points in Your Insulation

The right amount of insulation throughout your home keep your rooms cooler in summer and warmer in winter. Many homes, however, were built with just enough insulation to meet building code minimums, but too little for optimal energy efficiency.

Your energy audit technician will use an infrared camera to spot where your home is losing or gaining excessive amounts of heat. This shows you where insulation is lacking, so you can add more. Loose-fill (blown-in) insulation makes it possible to add insulation to walls and floors with tearing them out.

Energy audits make use of specialized equipment and professional expertise to find points of energy loss you’d otherwise overlook. With the information they provide, you’ll know exactly which home upgrades to invest in for the greatest improvements in comfort and savings.
