When leaving for a vacation, it can be easy to overlook the steps needed to prepare your home for temporary vacancy. You might ask a neighbor to pick up your mail, water your plants, and walk your dog, but home maintenance can fall by the wayside. During the winter, it’s advisable to turn off your main water valve and maintain consistent heat indoors so that your water pipes don’t burst, but what about your air conditioning during the summer? Since you won’t be home to enjoy the cool air, it could see like a safe idea to turn it off. But to avoid damage to your home, you’ll still want to maintain a consistent indoor temperature during the summer as well. This article will evaluate the risks of turning off your air-conditioning while vacationing in the summer.

Rampant humidity

Air conditioning doesn’t just cool down your home. It also controls humidity levels. For optimum comfort and health, the humidity in your house should be no higher than 50%. More than that and you run into condensation and common humidity problems, such as:

  •         Mold
  •         Musty smells and odors
  •         Peeling paint
  •         Warped wood furniture (floors, cabinets, etc.)

Stress on appliances

Although refrigerators and freezers are made to produce maintain cold environments, they still have to function without a certain ambient temperature range. A temperate environment aids them in completing their tasks, while an environment that’s too hot will over work your large appliances. Turning off your air conditioning could:

  •         Place stress on your refrigerator/freezer
  •         Increasing energy bills
  •         Cause breakdowns
  •         Spoil food in your pantry

Damaged Electronics

Televisions, video game systems, alarm systems — most modern homes are full of electronics. Underneath the electronics’ casing or cabinets, are a configuration of sensitive circuits that have been soldered together. High temperatures can melt soldering and fry circuits, ruining electronics. Allowing your home to reach high temperatures can cause the following damage to electronics:

  •         Melted circuits
  •         Damaged motors
  •         Cracked screens


For most homeowners who are going on vacation for a week or two, it’s probably best to keep your air conditioner on. But there’s no need to cool your entire home the same way you normally do – so turn your thermostat up. Usually a setting it around 83-86 degrees is good. This should run your air conditioner enough to remove excess humidity and keep other parts of your home safe. If you use a programmable thermostat, look for a “vacation”, “hold” or “away” function. These settings will keep your thermostat from cooling your home to your normal schedule.
