It can be hard to track down all the ways in which you can save money by insulating your home, so it’s a smart move to sign up for a home energy audit. Many utility companies will conduct one for you, sometimes for free. They’ll pinpoint many ways that you can increase your home’s energy efficiency and save money on your annual energy bills — such as by having insulation blown into your walls and sealing certain cracks and gaps. In addition, they may offer information on available tax credits or other incentive programs you might take advantage of. A particularly nice aspect of this is that you’ll likely be able to see which fixes will save you the most, so that you can be strategic in the actions you take.
