Ideal Temperature for an Empty House

Well lit furnished room with no people inside.

If you're like most people, you probably have a pretty good idea of what temperature you like to keep your home at when you're there. But what about when you're not going to be home for a while? What's the best temperature to set your thermostat at in that case? As we head into fall, kids will be going back to school, and there will be fewer people in the house during the day. In this blog, we’ll discuss the ideal temperature to keep your house when no one is home.


The ideal temperature to keep your house at while no one is home is 78 degrees. Here's why:

First, maintaining a constant temperature is better for your home's HVAC unit. When you make large swings in temperature (like turning the AC way down when you leave for work), your unit has to work harder to maintain the desired temperature. This puts extra wear and tear on the unit and can shorten its lifespan.

Second, keeping your house at a constant 78 degrees will save you money on your energy bills. Again, because your HVAC unit won't have to work as hard to maintain the temperature, it will use less energy - and that means lower bills for you. According to the Department of Energy, for every degree you lower your thermostat, you can save around 3 to 5 percent on your overall energy bill.


One way to help maintain your temperature in your home is to install a smart thermostat. This type of thermostat is easier to control and set to maintain the same temperature. It can be controlled by an app on your phone, which means you’ll never have to leave the couch to change the temperature. You can also control the temperature remotely, meaning if you remember while you’re out that you left the house too warm, you can turn the temperature down before you return.

How We Can Help

Another great way to ensure your home is well taken care of when you’re away is to not skip regular HVAC maintenance.

By keeping up with regular maintenance, you help reduce the likelihood of your system overheating, overworking, or stopping together. Our team of experienced HVAC technicians can help stop any and all issues in their tracks.
