This is a question that gets asked a lot from people who are debating whether to replace their existing AC system.
While there are many variables that go into just how much electricity will be saved, on average based on other’s experiences, you can save 30% to 40% on your monthly bill. The older the system you replace, the more you will save.
New AC units are much more efficient at removing the heat from the air than a system that is 15 or more years old. Also, those older systems are more likely a 11 SEER or less since at that time that was all that was required. Now, the minimum SEER value is 14 for new installs.
To take advantage of a new ac system and really help reduce your power bill, you need to make sure your home is also adjusted to help keep the cool air in. This will keep the ac system from constantly running and require fewer startups during the day.
Here are some improvements you can perform that will help you get the most out of your new AC unit.
- Check all your doors for gaps. Most often, the door sweep on the bottom gets worn and no longer creates a good seal. If you can see daylight under your door during the day, then cool air is escaping. Replacing the door sweeps will fill that gap and help keep cool air in.
- If you have ceiling fans, make sure they are set for the summer. Ceiling fans can be set to either blow the air down or up depending on the season. For summer, you want the fan to be blowing the air up sense cold air sinks. This moves the cooler air more freely throughout the room.
- Consider putting UV film on your windows. This can be purchased on-line or at a Home Depot and can have a dramatic effect on keeping the room cooler.
- If you have solar shade screens that are more than 10 years old, it is time to replace the screen material. Over the years, the screens lose their ability to repel the solar rays. You will notice that older shade screens no longer look dark and if they are old, you can almost see into the home. Replacing the solar screens can help keep a room up to 10 degrees cooler that one without. This means, your AC doesn’t have to work as hard.
- Always replace your filter when they become dirty. Depending on the filter type you use, every 1 to 3 months is a good rule of thumb.
- Some thermostats allow you to set the swing value temperature. This is the number of degrees the temp must change before the system turns on to maintain the temperature set point. Most thermostats are set to 2 and some even 1 degree. This means, the AC system is going to start more times during the day. If you change the swing value to 3 degrees, the ac unit will not startup as often and will run longer when it is running. The startups use a lot of power so reducing the number of startups will help reduce the amount of electricity consumed throughout the day.
