How Much Could You Really Expect to Save with New Windows in Your Toronto Home? February 11, 2015 Maybe you heard that you can save a lot of money by replacing the old, outdated windows in your Toronto home. That sure sounds like it could be a slick marketing campaign line, so what is the truth about how much you can really expect to save with new windows? That all depends on a number of factors. First and foremost, it depends on what temperature you set your thermostat at within your home. It also depends on the temperature outside. If you’re talking about winter time, one winter could be extremely cold and the next a bit more mild. A colder winter will cost you a lot more on heating expenses. It’s the same when you’re talking about summertime and air conditioning. Also, if you keep your thermostat set higher during the winter than your neighbor, you’re likely going to spend more money heating your home. Every degree increase in thermostat temperature setting will increase your home’s heating expenses. The next factor you need to consider has to do with the type of windows you have in place right now. If you have very old windows that don’t have any seal in place anymore, and you replace it with a double or triple glazed windows that are sealed with argon or krypton gas, you could increase the energy efficiency by up to 80 or 90 percent over those old windows. If you calculate that 40 percent of a home’s heat is lost through drafty windows and doors, you can begin to calculate just how much you may save on your heating expenses every month throughout winter and then cooling expenses during the summer. So, for example, if you spend $1,000 every month heating your home during the winter, 40% of that is $400. If you increase energy efficiency of your windows by 80%, that equals $320 a month in savings. Will you get that much by choosing replacement windows now? That all depends on the previously mentioned factors. However, it should give you a clear indication about just how much money you could save on heating, electric, and other utility bills throughout the year.
