Heat leaks out of your home in some cases as fast as your furnace can produce it. The more heat that leaks out of your home, the harder and longer your furnace has to work to heat it back up again. Not only will helping your home retain heat help to keep your heating costs down, it will also help to reduce the need to repair or replace your furnace. Anything you can do to improve your home's insulation envelope can protect your wallet.
Use Window Film
Windows trap a layer of gas between the panes of glass to isolate the outside pane from the inside pane. When the outside wind cools your window, the gas in between will stop some of the heat from your home from passing through to the outside world, but it will not stop all of it. On the other hand, if you use a reflective window film, you can reflect some of the heat back into your home. In this way, you can reduce your heating costs by up to 25%. The same window film can also reduce your cooling costs by 23%.
Check Your Door Trim
Outside doors should have a lining of weather-stripping along the door trim. This weather stripping will prevent heat from leaking around the edges of the door. Unfortunately, daily use, changes in the temperature, or objects scraping across the door trim can damage the weather stripping. Run a stick of incense along your door when it is shut. If air leaking around the door disturbs the smoke from the incense, you need to replace your weather stripping.
Use an Area Rug
If you have a lot of wood or tile floors in your home, they will do little to insulate your home. Using area rugs will help to insulate your floor. Not only will this make it more comfortable to walk across the floors in your home, it will help to prevent cold air from your crawl space from leaking into your home.
The fixes described above are little things that can make a big difference in your home's insulation envelope. If you want to keep your cooling costs down but don't feel like you have the money available to make a big change, then you should start with at least one of the small changes described above. You can make the other changes as you have the money available to make them. Contact a heating service in your area for more information.
