Get a programmable thermostat and set the temperature right when going out. For example, if you are going to work, set the temperature lower during winter and higher in summer. It will help ensure that your home has a comfortable environment when you arrive back, and the same can be done before going to bed. A programmable thermostat can be a valuable investment. It can help improve the system’s efficiency, convenience and save you money.
Air leak through doors and windows can also be a big energy eater, so get your doors and windows checked once every 6 months for any cracks or damages. You can yourself caulk any gaps or cracks in the weather stripping or window frames. Leaks can also happen through the ductwork, so make sure to check them too for any gaps. Your heating and cooling services can also provide professional inspection for the ductwork.
