Having an efficient furnace goes a long way toward cutting your heating costs, but if your home lacks adequate insulation, has heat losses through the windows, or substantial air leaks, you may not notice as much savings. One of the best ways to learn if you could achieve lower energy bills is with an energy audit that you or a professional can perform.
A professional audit will show you where you have air leaks throughout your home's exterior and detect any leaks in the ductwork that cause high energy consumption. The auditing team will also evaluate your attic insulation to see if and where you need more. The centerpiece of the audit is a blower door test that pulls the air from your home and pulls it inside anywhere you have leaks and gaps. The professionals pinpoint the locations using thermographic equipment that shows the temperature difference between the incoming air.
You can perform your own audit by closing up your home and turning on the kitchen and bathroom fans. As you walk through your home with a candle or incense stick, note where the smoke wavers, indicating a leak. Once finished, you can seal smaller air leaks with suitable caulk. Expanding foam will seal larger leaks around the foundation or in the attic. Weatherstripping around exterior door frames will tighten the seal.
The recommended level of insulation in attics in this region stands R-38 or 16 inches. Increasing it will quickly help your efficient furnace run less. Thermal losses from either the roof or the windows increase the need for heat substantially.
Windows are a bit more challenging to weatherize, but doing so will cut your heating costs. Options include replacement with Energy Star or thermal windows, but if those aren't in the budget, consider plastic window kits that stop some of the heat transfer. Heavy drapes will also stop the losses, especially when they lie close to the window.
