One of the easiest ways to lower your energy bills is to improve the efficiency of your home. Many upgrades, like adding insulation or sealing air leaks, are projects you can do yourself. Here are some effective upgrades you can tackle to save energy and money.
Adding weatherstripping around doors and windows is an inexpensive way to improve the energy efficiency of your home. Weatherstripping seals gaps and cracks to reduce drafts and prevent heat loss. You can find weatherstripping kits for around $30 at your local hardware store. Installation only takes a few hours and can lower your heating and cooling costs by up to 20 percent.
Insulating your attic is another useful upgrade. Heat rises, so much of the warmth in your home escapes through the attic. Adding insulation, especially in older homes, can significantly improve the energy efficiency of your space. For around $20, you can get a bag of loose-fill cellulose insulation to add to your attic. Properly insulating your attic can lower heating costs by up to 30 percent.
Replacing incandescent light bulbs with LEDs or CFLs is an easy way to start saving energy. LEDs and CFLs use at least 75 percent less energy than incandescent bulbs and last up to 25 times longer. Make the switch to energy-efficient lighting and you’ll notice lower electricity bills right away.
Installing a programmable thermostat allows you to more efficiently control the temperature in your home. A programmable thermostat can automatically adjust the temperature for maximum energy savings when you are away or sleeping. Smart thermostats, like the Nest Learning Thermostat, can learn your habits and preferences to optimize energy usage. Installing a programmable thermostat typically costs between $50 to $250 and can lower both heating and cooling costs by up to 10 percent.
Sealing and insulating your ductwork prevents heat loss as warm air circulates through your HVAC system. Sealing leaks and holes in your ducts with mastic sealant or metal tape can improve the efficiency of your heating and cooling by up to 20 percent. Insulating ducts that run through unheated areas like the attic or basement keeps heat from escaping. Sealing and insulating ductwork typically costs between $50 to $200, depending on the size of your system.
