Should You Leave Your Thermostat On One Temperature Or Change It?

The thermostat is the key to keeping your house a comfortable temperature during the frigid winter and scorching summer. And everyone seems to control their thermostat differently – some micromanage their temperature settings, changing them constantly, while others set it to one temperature and hardly ever change it.

But is there a right way to set your thermostat’s temperature? It turns out, there are pros and cons to each method, and that’s exactly what we’re going to look at in this article. Let’s first start with the pros and cons of setting your thermostat to one temperature for the entire day:

Pros of Leaving Your Thermostat at One Temperature

People leave their thermostats at constant temperatures for various reasons. Some simply find the steady temperature comforting, while others just don’t want to go through the effort of changing it all the time. But as it turns out, the only real pro to keeping your thermostat one temperature is convenience. Sure, when you’re away on vacation or gone for the weekend, the consistent temperature is efficient, but when you’re at home, there’s really no additional benefits.

Cons of Keeping Your Thermostat at One Temperature

The biggest takeaway here is that leaving your thermostat at a consistent temperature is actually an inefficient way to run your HVAC when your at home.

Here’s how:

Consistent Temperatures Can Cause Heat Energy Leakage

In most cases, leaving the thermostat temperature constant is aimed at keeping the thermal energy (heat) inside the homes constant. Consequently, inside the house will often be warmer than the outside.

To understand how this works, let’s talk about how heat moves from one area to another. Heat is transferred from a region of high concentration to a region of low concentration. As a result, the heat energy required to maintain the temperature at the hotter region includes the energy “leaked” to the other end. The higher the temperature difference between the two points, the faster the heat loss to the surrounding area.

The same applies to house temperatures. The higher the temperature inside compared to the outside, the more rapidly energy leaks out. Maintaining this energy leakage can seriously rake up your utility bill.

The Most Efficient Way to Control Your Thermostat

To help you run your HVAC more efficiently and help you save money on your utility bill, there are a couple of tips you can follow:

Follow the 8-Hours Routine

The easiest way to remember to change your thermostat settings is to follow your work routine, or an 8-hour routine. In other words, change your thermostat to a more efficient setting when you leave for work and then change it back when you come home.

The most efficient settings reduce energy leakage. In other words, try to get as close to the outside temperature as possible without making your home uncomfortable. Obviously, you don’t want to set your home to 40 when it’s 40 outside, or 90 in the summer.

Making just a few adjustments can have a big impact. So if you set your thermostat to 65 when it’s 40 outside, try bumping it down to 60 or even 55 when you leave for work. Or if you normally keep your home at 70 when it’s hot outside, bump it up to 75 or even 80 when you’re not home and then bring it back down when you come back. Little changes like this can reduce your utility bill by 15%

The Benefit of Programmable Thermostat

If you want the ideal solution for energy efficiency, opt for a programmable thermostat. After a few days of routine adjustment, the programmable thermostat will begin doing the work for you. Studies show that those who let it do the job for them save more than thermostat micromanagers.
