Straight Talk on Your Summer Electric Bill

Where the money goes

Every July the electric bill jumps, and the AC gets the blame. It’s usually right. In a Colorado summer, cooling is the biggest swing in a home’s energy use, and small choices about how you run the system add up to real money over a season.

The good news is that the cheapest improvements are also the easiest. You don’t need new equipment to shave a summer bill. You need to run what you have a little smarter.

The changes that actually pay

Start with the thermostat. Every degree you raise the setpoint saves roughly 2 to 3 percent on cooling. Set it to 78 when you’re home and let it drift to 82 or higher when you’re out, and the savings compound across a hot month. A programmable or smart thermostat does this for you so you don’t have to remember.

Change the filter. A clogged filter makes the blower work harder and cuts efficiency, and it’s the single most-neglected maintenance item in most homes. A clean one is a few dollars.

Close the blinds on the sunny side. Solar heat pouring through west and south windows in the afternoon is heat your AC has to remove. Shading those windows cuts the load before it starts.

What helps less than you’d think

Some savings ideas sound good and deliver little. Closing vents in unused rooms doesn’t help the way people expect; it throws off the system’s designed airflow and can raise pressure enough to hurt efficiency. Leave them mostly open.

Turning the AC off entirely while you’re at work, then blasting it cold when you get home, saves less than a modest setback. The system runs flat out to recover, and in a well-shaded house the difference is small. A steady, moderate setpoint usually beats big swings.

And chasing a colder-than-needed house is just paying more. Every degree below 78 is roughly another 2 to 3 percent, night after night.

The bigger picture

If your bills are high despite doing all this, the equipment itself may be the story: an aging, low-efficiency AC, leaky ducts bleeding cooled air into the attic, or a system that was oversized and short-cycles. Those are worth a look, because they cost you every summer.
