Better Ask Barry: Lowering summer energy costs

For many on the Central Coast, our air conditioning is free. The cool ocean air keeps things pretty moderate year-round.

But in the valleys and above the marine layer, it can get downright hot.

If you haven’t had you’re A/C system checked recently, it might be time.

“So many people are doing life, and the next thing you know, the A/C has stopped, and they check and se it’s been six years since we had anyone look at the thing,” said Clay Ewing, an A/C expert.

In simple terms, you need to allow your unit to breathe, inside and outside.

Homeowner Katie Andrews says she changes her home’s A/C filters once a month because she knows from past experience that clogged filters can cause expensive problems.

And when it comes to the unit itself, give it some space.

“You need to keep 36 inches of clearance around the unit if you can so it can breathe,” said Andrews. “That’s manufactures’ specifications.”

While it’s tempting to lower the thermostat to a cool 68, those lower temps can lead to a higher electric bill.

The U.S. Department of Energy says you’ll save 3% with every degree you raise the temperature setting.

And if you can, regulate the temperature by time of day.

“I have a nest system for my A/C, so during the day it will heat up when we’re not home, but in the evening it’s cold,” said Andrews.

The Energy Department recommends you use the following temperature settings for your A/C to save energy costs:

78 degrees when you’re home 82 degrees when you are sleeping 85 degrees when you are at work or away
