When it comes to taxes, one of the last words you'd like to hear is "audit." When it comes to your energy bills, an audit is a great way to protect your pocketbook. If you want to know how much energy and money is flying out your window and doors, do your own audit. Grab a candle or a lighter and go on a draft hunt: check where walls meet ceilings and floors, around electrical outlets, windows, door frames and baseboards. Wherever you see or feel a draft, seal it. This can slash your utility bill by 30%. Not a do-it-yourselfer? Ask your utility company if they'll do an audit for you. "With the price of fuel going up and more people wanting to go green and help environment, it's become very popular to do home energy audits…" It takes more than two-hours of comprehensive tests to get the bottom line: "This is going to tell us, when we put the data in the computer, the overall leakiness of the house..." The auditor checks filters… intakes… and every single air duct in your home. "This is not good, this is a disconnected duct." Even your hot water's temperature is taken. Your auditor will tell you what to fix and mark leaks for a repair contractor. The repairs aren't free, but sometimes the utility company will help offset the cost with credits.
