In 2013, you can make the choice to be more energy efficient with your HVAC unit. It doesn’t take much work, just these three easy things, and you will be seeing lowered utility bills and know you are more eco-friendly. Giving back to the environment doesn’t have to involve large costly endeavors, they can be small things that, when in the habit, aren’t even thought about.Adjust Thermostat TemperatureIf you don’t have a programmable thermostat, get one. These can save you money in energy costs and they are convenient. When you are away from your home, set the controls to be higher/lower than needed (depending on season). Heating and cooling your home or office when you aren’t there is an energy waste that drives up your electricity bill. With a programmable thermostat you can have the unit turn on a bit before you get home, so that you are comfortable without having it stay on that thermostat setting the entire time you aren’t home. Try to keep the thermostat off when you are sleeping, adjust bedding and clothing as needed because of this. Also, try to pick a temperature and stick with it, adjusting back and forth loses energy efficiency and also makes your bill higher.Don’t Forget MaintenanceA yearly or bi-yearly maintenance can seem like a costly endeavor, but it is just the opposite. Getting everything checked out, typically in the spring and fall, is a good way to see faulty items before they become big problems. Also, cleaning the unit and lubricating all the parts keeps the HVAC system working well and efficient, with less of a struggle. A qualified HVAC technician can put you on a maintenance plan that is convenient for you and give you piece of mind for the entire year.Change Out Your FiltersFilters should always be changed at least every three months, but every month is the best way to be energy efficient. Dirty filters work harder and will slow down air flow. This makes the system work harder to do the same job, and taxing the system defeats energy efficiency. The longer your HVAC unit works harder than it has to, the quicker you’ll need costly repairs or suffer a complete system breakdown. This easy and simple way to be more energy efficient and lower your heating and cooling bills should be the main thing you remember to do in 2013. Pick a day and have that be your monthly day to change the filter out on the system.
