Warm Weather Thermostat Settings: By Time of Day

Warm Weather Thermostat Settings: By Time of Day

There are a few components in your HVAC system that play a huge role in both your daily comfort and your utility bills, and the thermostat is perhaps the single top example here. The thermostat is in charge of identifying temperature levels and sending required actions to the components within the system, and as we get into the warmer parts of the year, many homeowners are looking to set their thermostats ideally to both stay comfortable and save money.

At Airtime Heating & Cooling, we're here to offer numerous heating and air conditioning repairs, tune-ups, installations and more for clients around Riverton, Lehi, Bluffdale, Herriman and other parts of Utah. In this two-part blog series, we'll go over everything you need to know about thermostat settings in the spring and even the dead of the upcoming summer - today's part one will focus on typical times of day and how to set your thermostat within them, while part two will look at certain specific scenarios or settings where thermostat settings may be helpful.

Role of a Smart or Programmable Thermostat

Before we dig into specific settings, it's important to note that if you have a smart or programmable thermostat, it can be a major help in both comfort and cost savings. These thermostats allow you to set different temperatures at different times of day and even days of the week, so you're not cooling or heating when you don't need to be.

If you don't yet have such a thermostat, it may be worth considering - they can pay for themselves in energy cost savings over time. Just the simple ability to lower temperatures when you're asleep or away from home can make a big difference.

Standard Daytime Periods

During a normal day, how you set your thermostat will depend largely on whether anyone remains home for the bulk of the day, and your own personal temperature preferences.

If you work outside the home or have kids in school, you'll want to set a slightly higher temperature when you're away to save energy, perhaps around 78 degrees Fahrenheit or so. When you return home and are active in the house, you can lower it to around 72-74 degrees for comfort.


Assuming more people are typically home in the evening, you'll want to set your thermostat to a comfortable temperature for family time and sleeping. For many, 70-72 degrees is ideal for evening hours. If it's just you at home and you prefer it a bit cooler for sleeping, you might go down to 68 or so before bed.

Night Time

During the actual sleeping hours, you can lower the thermostat even more to 65-68 degrees to save energy while you're less active. If you find this too cool for sleeping comfortably, you may only lower it a degree or two from your evening setting. But any adjustment down at night can help with energy efficiency and cost savings.

In part two of our series, we'll look at ideal thermostat settings for certain specific activities or settings. For any issues with your thermostat or HVAC system, contact Airtime Heating & Cooling for professional service and repair today!
