Not all HVAC systems are the same, and it's important you find the right one for you. A great HVAC system should be high-efficiency. A high-efficiency HVAC system is one that runs on less energy and runs at a higher efficiency than other HVAC systems. There are many benefits to a high-efficiency HVAC system, including lower energy costs, being eco-friendly, better air quality, less noise, better temperature control, fewer repair costs, and a significantly higher resale value. Having a high-efficiency HVAC system should be paired with setting your thermostat at the ideal temperature.

The Ideal Temperature for Your Thermostat

There is no one temperature that your thermostat should be set at all year round. However, depending on the season and whether you are home, there are certain temperatures that help your HVAC system run as efficiently as possible. In general, the ideal home temperature falls between 70 and 78 degrees Fahrenheit.


During summer, the best thermostat setting is 78 degrees Fahrenheit when you are in the home. If you are away from the home during the summer, you should either set your temperature even higher or turn it off completely. Cooling a home that no one is in can be quite expensive. As is the case with winter temperatures, you will need to keep the needs of your pets and children in mind when setting your temperature. Young children typically shouldn't be in temperatures higher than 74 degrees Fahrenheit for long periods of time. Depending on the pets you own, they may or may not be comfortable in higher temperatures. For instance, dogs like Siberian Husky's enjoy the cold, so they might find the higher temperature to be uncomfortable.

If you are consistently out of your home at the same time each day, you can use a programmable thermostat to automatically set temperatures to the temperature you want it to be at specific times. This way, you don't have to worry about remembering to change it. Whatever temperature you decide to set your home at, you should not try to cool it faster by setting your thermostat to a cooler temperature setting than you usually do. Not only will this not make your home cool faster, you might end up with your home colder than you want it to be.


When you are sleeping, your body temperature actually drops, which means the best temperature for sleeping falls in the range of 60-67 degrees Fahrenheit. If your home is too cold or too hot, it can influence your internal body temperature, which can cause you to sleep poorly. Keep in mind that if you have small children in the house, you want to keep the temperature between 65 and 74 degrees Fahrenheit at all times.

What Is a Programmable Thermostat?

A programmable thermostat is a device that allows you to set a schedule of temperatures for your home. They can store and repeat several daily settings, so you don't have to think about changing them. So, for example, if you know you won't be home from 9-5 each day, you can set the thermostat to lower or raise the temperature automatically during that time. Then, you can have it set to return to the temperature you want it to be when you arrive home. You can generally override these settings if you end up home at a time you aren't expecting.


Having a high-efficiency HVAC system and using a programmable thermostat can help you save a ton of money. There are many programmable thermostats out there, so you can find the one that works best for you.
