Does Lowering a Thermostat One Degree Really Save You Money?

HVAC Accessories

The Short Answer Is: Yes! Lowering a thermostat by one degree can save you money on your heating or cooling bills. The exact savings depend on factors like climate, insulation, and the efficiency of your HVAC system, but it's estimated to reduce energy costs by around 1-3% per degree for each 8-hour period. Over a year, this can add up to significant savings.

In the quest to reduce home energy consumption and lower energy costs, the temperature at which we set our thermostats is a frequent topic of debate. While the idea of reducing your HVAC thermostat by just one degree may seem like a negligible change to save energy, the cumulative impact it can have on your wallet and the environment is nothing to scoff at.

Let's delve into the science and economics of this small yet significant adjustment and find out does one degree make a difference on thermostat settings.

The Science of Lowering the Thermostat

Before we explore the financial aspects, let's first understand the science behind lowering your thermostat by just one degree for energy savings. On a fundamental level, it's about reducing the temperature difference between the temperature inside and the outside temperature. Your heating and cooling system must work harder to maintain a larger temperature differential. As you lower the thermostat temperature, the system consumes less energy because the temperature gap your heating or air conditioning system needs to bridge is smaller.

Moreover, the rate of heat transfer between your home and the outside environment is directly proportional to the temperature difference. The larger this difference, the faster your home will gain or lose heat. By lowering your thermostat, you slow down the rate of heat exchange, making it easier for your HVAC system to maintain the desired indoor temperature.

The Economics of One Degree

Now, let's discuss the financial implications of reducing your thermostat setting by a single degree. It might not seem like much, but the savings can add up over time. Here's a breakdown of how this small adjustment in temperature changes affects your energy bill and will allow you to save money on heating and cooling costs:

Lower Heating Costs

In the winter, lowering your thermostat by just one degree can reduce your energy bill by around 1% for each degree lower you set it, according to the U.S. Department of Energy. For instance, if you typically keep your thermostat at 70 degrees Fahrenheit and reduce it to 69 degrees, you could save about 1% on your heating bill. While it might not seem substantial for a single degree, if you lower the thermostat temperature settings several degrees over the course of a heating season, you conserve energy and the annual savings become more significant.

Decreased Cooling Costs

In the summer, the principle remains the same but applies to your cooling costs. A thermostat adjustment of just a single degree can lead to a similar reduction in cooling expenses and increased system energy efficiency. The less your air conditioner has to work to maintain the temperature setting, the less energy it consumes. Over the course of the cooling season, these savings can accumulate, potentially saving you a noticeable amount in energy costs.

Lower Maintenance Costs

The wear and tear on your HVAC equipment also decreases when it doesn't have to work as hard to maintain the desired temperature. This can translate into lower maintenance and repair costs, as the system is subjected to less stress and operates more efficiently.

Extended HVAC Equipment Lifespan

Reducing the workload on your heating and cooling equipment can extend its lifespan. Since the system isn't running at full tilt to maintain a wider temperature differential, it's less likely to experience premature wear and tear, reducing the need for costly replacements.

Lower Environmental Impact

Savings don't stop at your wallet. Lowering your thermostat has a positive impact on the environment by reducing energy consumption. This, in turn, lowers greenhouse gas emissions, helping combat climate change. The more people make these small changes, the greater the collective effect on the planet.

How to Implement the Change

Now that we've established that lowering your thermostat by one degree can indeed save you money, let's explore how to make this change effectively.

Invest in a Programmable Thermostat or Smart Thermostat

One of the simplest ways to manage your thermostat is by investing in a programmable thermostat or smart thermostat. These devices allow you to set different temperature profiles for different times of the day and week. Programmable thermostats can be set to lower the temperature when you're not at home or when you're sleeping, and raise it when you're awake and active - smart thermostats are able to make this change on their own. This automation ensures that you don't forget to make the adjustment and maximizes your savings.

Dress for the Weather

In the colder months, layering up and using blankets can help you stay warm while keeping your thermostat lower. Similarly, in the summer, dress lightly and use fans to stay cool. These simple adjustments can help you maintain comfort without relying on your HVAC system as much.

Sealing and Insulation

Make sure your home is properly sealed and insulated to prevent drafts and heat loss in the winter. This will allow you to maintain a comfortable temperature with less reliance on your heating system. In the summer, proper insulation can keep the hot outdoor air from infiltrating your home, reducing the workload on your air conditioner.

Save Energy with the Right Thermostat Settings

In the grand scheme of things, lowering your thermostat by one degree might seem insignificant. However, when you consider the cumulative savings on your energy bills, the positive impact on the environment, and the potential reductions in maintenance and repair costs, this small adjustment is anything but trivial. It's a simple yet effective way to manage your energy consumption, save money, and contribute to a greener planet.
