Beat the Heat: 8 Energy-Efficient Ways to Maximize Your Air Conditioning System
With temperatures rising, it’s important to ensure your air conditioner is working at maximum efficiency to help you beat the heat. But how do you get the most out of your AC and ensure it runs efficiently?
In this blog, we’ll discuss eight ways to ensure your air conditioning system is performing optimally. Whether you’re using a central air system or a window unit, following these tips will help you maximize your AC’s efficiency and keep your home cool during those hot summer months.
1. Change Air Filters to Boost AC Efficiency
One of the most important steps towards achieving maximum efficiency from your AC is changing your air filters every one to three months, depending on usage and filter type. Clogged or dirty filters can restrict airflow, trigger allergies, and reduce the performance of your system, so keep an eye on them and replace them as needed.
2. Keep Outdoor Central Air Conditioner Unit Clean
It’s important to keep the outdoor unit of your AC system clean and free of leaves, branches, or other debris which can obstruct airflow and reduce efficiency. Make sure that you are taking time to regularly check and clear out any blockages around the outdoor unit.
3. Seal Ducts and Vents for Better Cooling System Performance
Poorly insulated ductwork or leaking vents can cause your system to work harder, reducing its efficiency. Ensure that all of the ducts in your home are properly sealed with insulation to keep cold air inside and hot air outside.
4. Program Your Thermostat to Use Less Energy
To get maximum efficiency out of your AC, it’s important to set your thermostat at the highest comfortable temperature and program the AC according to your daily routine. This will help ensure you’re using energy efficiently and keeping temperatures consistent throughout your home.
5. Use Ceiling Fans to Support Your Air Conditioning System
Ceiling fans are a great way to make a room feel cooler without running the air conditioning at full blast. They help circulate the air and keep the room cooler, so you can turn up your thermostat a few degrees to save energy.
6. Close Blinds to Trap Cool Air and Improve Efficiency
Keeping window treatments drawn during hot days can help block out the sun’s heat and keep your home cooler by trapping cold air in.
7. Keep HVAC Vents Open for Consistent Cool Airflow
Keep all of the supply and return air vents in your home open, as this will help ensure adequate airflow throughout the system and maximum efficiency from your AC.
8. Schedule HVAC Maintenance for Better SEER and EER
Finally, it’s important to ensure you are scheduling regular maintenance for your air conditioning system. A trained AC technician can help identify and repair any underlying issues that might be reducing the efficiency of your system.

FAQ About AC Efficiency and Energy-Efficient Air Conditioning Systems
What is a good efficiency for an air conditioner?
A good air conditioner efficiency rating depends on the type of unit. For central air conditioning systems, a SEER rating (Seasonal Energy Efficiency Ratio) of 14 or higher is considered good, while Energy Star certified units typically offer SEER ratings of 15 or more. The higher the SEER or EER (Energy Efficiency Ratio), the more energy-efficient your cooling system is, resulting in better energy savings and lower energy bills.
What is the $5000 AC rule?
The “$5000 AC rule” is a guideline to determine whether you should repair or replace your air conditioning unit. Multiply the age of your AC unit by the estimated repair cost. If the total exceeds $5,000, it’s usually more cost-effective to purchase a new energy-efficient air conditioner. New air conditioners meet efficiency standards set by the Department of Energy and can save significant energy compared to older models.
Is 72 a good temperature for air conditioning?
Yes, setting your thermostat to 72°F is considered a comfortable and energy-efficient temperature for most homes. However, increasing the set temperature to 75°F–78°F while at home and even higher when away can help save energy and reduce energy usage without compromising comfort. The goal is to maintain cool air while minimizing energy consumption.
How efficient is a 20 year old air conditioner?
A 20-year-old air conditioning system is significantly less efficient compared to today’s high-efficiency units. Older models may have a SEER rating below 10, while newer Energy Star certified systems must meet a minimum SEER of 14 or higher. Over time, wear and lack of modern technology can increase energy use, reduce cooling performance, and increase energy bills.
Should I replace my 25 year old AC?
Yes, replacing a 25-year-old AC unit is highly recommended. Most air conditioners have a typical lifespan of 10–15 years. Beyond that, they become inefficient and costly to maintain. Upgrading to a new energy-efficient air conditioner improves cooling capacity, lowers energy usage, and meets the latest energy efficiency guidelines set by the Department of Energy.
At what temperature AC is most efficient?
Your AC is most efficient when set at 78°F while you are home and active, according to energy efficiency experts and the Department of Energy. This temperature helps maintain cool air and comfort while minimizing energy consumption. Using fans and keeping blinds closed can support cooling performance and allow you to raise the temperature settings slightly for more energy savings.
