Stop newspaper delivery – check. Shut off the water supply to prevent flooding – check. Have a neighbor keep an eye on your house and water your plants – check.

While there is no doubt plenty of other pre-vacation planning and preparation measures on your list, have you decided what to do about your central AC system while you’re gone? Hopefully, the following advice will help.

 

Don’t turn your AC system off

One way an AC system does its job is by removing humidity. So, turning it off not only keeps the cool air away, but allows indoor humidity to build up without necessary restraints.

For optimum comfort and proper home care, keep indoor levels between 30 – 50% relative humidity. A simple hygrometer available at local home centers will help you keep track.

Without humidity control, you’re likely to face these and other problems:

  • Mold build-up on surfaces and in the air

  • Musty smells and odors

  • Peeling paint

  • Warped wood furniture (floors, cabinets, etc.)

Turning off the AC system during your vacation also can lead to:

  • Refrigerator damage from added stress

  • Food spoilage in your pantry

  • Damage to sensitive electronics

So, what’s a careful homeowner to do here in the Eagan, MN area?

Keep your AC system on, and turn your thermostat up

Keeping your AC system on doesn’t mean maintaining “cool and comfortable” temperatures.  You just want the interior to be cool enough to prevent damage from high heat and humidity. A setting of 83-86 degrees should be adequate, which means you’ll also see a nice reduction on your next electricity bill.

For greater peace of mind, consider replacing your main thermostat with a programmable model that also includes a Wi-Fi accessible app. That way, you can keep track of your AC system’s performance during your absence and contact a professional should you detect a problem. After all, who wants to come down to zero air conditioning? No one we know!
