The biggest thing you can do to save money is to change your air filter monthly. Writing the date
that you replace the filter on the edge of the air filter is a good way to remember whether you need
to change your filter or not.
For AC, the first thing to check is whether the thermostat is set to “Cool” and to “Auto”. If air is blowing, but it is hot, then go outside to see if the blades are moving on YOUR compressor unit (make sure you know which compressor is connected to your house). If the blades are not moving, then you need to arrange a service call. Make sure to switch your thermostat to the “Off” position. AC technicians can not work on a unit that is frozen, so if you leave your thermostat on
“Cool”, your unit will be frozen when they show up and you are just delaying the time before he can help you.
If no air is blowing in your house, check to see if the breaker is tripped in your fuse box. If it is
tripped, flip the breaker switch back on. If the switch is not tripped, you need to arrange a service
call.
Two final important tips:
1) If you want to minimize your electric bill, set your thermostat to 76 or 78 degrees during the day, then lower the temperature when you get home after work.
But don't turn the AC "Off" during the day. The reality is that it takes less electricity to keep the temperature withing a certain range all day than it does to turn the AC off,
then turn it back on when you get home to try and cool your house down during a short period of time.
2) Don't block the big air return grates with furniture, boxes or anything else. Free air flow is key for your AC to work efficiently.
