Upgrade Your Insulation
Using blown-in foam insulation in your attic and walls can help seal in the heat when it gets colder without the risk of altering your home’s structural stability. Depending on the age of your home, it may just have the minimum required insulation in place, which won’t be enough to help you save energy.
Instead of incandescent bulbs, use compact fluorescent lights, which use 75 percent less energy and last ten times as long! LED bulbs are also a great energy-efficient option, as they are mercury-free and can last up to 50 times as long as incandescent bulbs.
Seal windows and doors in order to retain heat by first making sure they are all properly hinged. Instead of metal window frames (which conduct heat), use insulated fiberglass or vinyl. Remove drying window caulk and replace it with a fresh seal to prevent excess heat from escaping, and install door sweeps on the bottom of your front and back doors.
Choose a Programmable Thermostat
Most hardware stores or supermarkets offer thermostats that can be set to automatically reduce heat or air at certain times. You could save a couple hundred dollars a year on your energy bill!
Many people aren’t aware that they should really be replacing furnace air filters every few months, not once a year or whenever you remember to get to it. Dirty air filters actually cause your furnace to use more energy.
