There are many low-cost DIY projects homeowners can do to help improve the efficiency of their homes and save money. Replace old light bulbs with Energy Star LEDS which are up to 85% more efficient than traditional incandescent bulbs. Start with the most frequently used areas in your homes like the kitchen and bathrooms. You can install a smart thermostat to reduce energy costs and keep your home comfortable. And don’t forget to seal up air leaks. Add weather stripping to doors and windows, and caulk any holes around duct work, plumbing and fans, inside and outside the home to get the most out of your heating and cooling system.
