As an HVAC expert, I have seen many homeowners struggle with finding the right temperature to keep their AC at during the summer. On one hand, you want to stay cool and comfortable, but on the other hand, you don't want to receive an unusually high electricity bill. So, what is the cheapest temperature to keep your AC at? Let's dive into the recommendations from the U. S.
Department of Energy and how it can translate into savings for you. The U. Department of Energy recommends setting your thermostat to 78°F (26°C) when you're at home. This temperature may seem a bit warm, especially during the scorching summer months, but it is actually the optimal temperature for both comfort and cost savings. By keeping your AC at this level, you can stay cool without breaking the bank. But why 78°F? According to experts, this temperature strikes a balance between energy efficiency and comfort.
It is not too cold that your AC has to work overtime, but it is also not too warm that you feel uncomfortable. In fact, for every degree you raise your thermostat above 72°F (22°C), you can save up to 3% on your cooling costs. Now, I understand that everyone's comfort level is different and some may prefer a cooler temperature. However, keep in mind that every degree below 78°F can increase your energy usage by 8-10%. So, if you set your thermostat to 75°F instead of 78°F, you could potentially be paying up to 30% more on your cooling costs. But what about when you're not at home? The U.
Department of Energy recommends setting your thermostat to 85°F (29°C) when you're away. This may seem high, but it is important to remember that your AC is not just cooling the air, but also removing humidity. By keeping your home at a consistent temperature, you can prevent mold and mildew growth, which can lead to costly repairs. Now, you may be wondering how you can remember to adjust your thermostat every time you leave the house. Luckily, most modern thermostats come with programmable features that allow you to set a schedule for different temperatures throughout the day.
This way, you can set it and forget it, knowing that your AC is running at the most cost-effective temperature. Aside from setting the right temperature, there are other ways to save money on your AC costs. One of the most important things is to regularly maintain your HVAC system. A healthy system can last longer and operate more efficiently, saving you money in the long run. Here are some tips to keep your system in top shape:
- Change your air filters regularly: Clogged air filters can restrict airflow and cause your AC to work harder than necessary.
- Clean the outdoor unit: Make sure there is no debris or vegetation blocking the outdoor unit as this can also restrict airflow.
- Get an annual tune-up: Hire a professional HVAC technician to inspect and clean your system once a year.
This can prevent any potential issues and keep your system running smoothly.
