Here’s how to keep your cool

Dear Heloise: Here are some hints for staying comfy and cool this summer while saving money:

■ Maintaining the air conditioner is critical. Schedule yearly maintenance to be sure everything is working properly.

■ Consider adding window treatments to keep heat out — awnings outside, blinds and curtains inside.

■ A “smart” thermostat can maintain an appropriate temperature for your home. Some can be controlled through an app on your phone.

■ Check windows and doors for leaks, and seal any you find. Additional attic insulation also might be called for.

■ Finally, as simple as it sounds, a cool evening breeze can replace the air conditioning. So, open a window! — Barry in Missouri

Tech Tuesday

Dear Readers: If you have an issue with a company, they may offer a live chat forum on their website where you can chat (message) with a representative who can help resolve the problem or direct you to someone who can.

The best part of the chat is that you’ll have the conversation in writing, so you can save the transcript for future reference. — Heloise

Never Have I Ever

Dear Heloise: I NEVER open my door to a stranger, even if it’s a kindly lady poised at the peephole. A team of bad men could be crouched down out of sight. — Hilda in Alabama

Hilda, sad but true. These people often work in teams, and although Southern hospitality is a wonderful thing, it’s always important to put safety first. — Heloise
