Install ceiling fans in most rooms.
Ceiling Fans are a low-energy way to keep air moving in your home. Because of the air circulation effect, you can get away with keeping your thermostat a degree or two higher in summer and a degree or two lower in winter, netting a rather large savings. The most important thing to know is that the air directly below the fan should be blowing down on you in the summer and should be pulled upwards away from you in the winter — you can use the reversal switch on your fan to switch between the modes at the start of each season.
Install a programmable thermostat – and learn how to use it.
A programmable thermostat allows you to schedule automatic increases and decreases in your home’s temperature, saving money on cooling in the summer and heating in the winter.They’re easy to install and easy to use, especially if you keep a fairly routine schedule. Just program the thermostat to drop a few degrees at night while you’re sleeping or off at work during the day, and set it to return to your preferred temperature just before you wake up or return home from work. You won’t notice the difference — until you see your lower utility bill.
Replace your air filters.
When you first move in, you almost always need to replace the filter on your furnace or AC unit. Don’t worry, it’s easy to do – it takes about 10 seconds. An outdated filter not only doesn’t filter air as well, it also has a negative impact on air flow, meaning your air handling system or HVAC unit has to work harder — and use more energy — to pump out lower quality air.
Make sure the vents in all rooms are clear of dust and obstructions.
None of the vents in your home should be covered or blocked by anything – doing that makes your heating and cooling work overtime. You should also peek into all of your vents and make sure they’re as dust-free as possible, and brush them out if you see any dust bunnies. This improves air flow into the room, reducing the amount of blowing that needs to happen.
