In the US, the minimum SEER rating for central AC units is 13. However, units with a rating of 16 or higher are recommended for optimal energy savings.

EER Ratings

EER stands for Energy Efficiency Ratio. It measures the efficiency of an AC unit at a specific temperature and humidity level. The higher the EER rating, the more efficient the unit is. EER is commonly used for room air conditioners and other smaller cooling units.

ENERGY STAR Certification

ENERGY STAR is a program developed by the US Environmental Protection Agency (EPA) to promote energy-efficient products. AC units that are ENERGY STAR certified meet strict guidelines for energy efficiency, performance, and environmental impact. Look for the ENERGY STAR label when purchasing a new AC unit.

When choosing an AC unit, it’s important to consider the size of the unit and your cooling needs. An oversized unit can lead to higher energy bills and poor performance, while an undersized unit won’t effectively cool your home. Consult with an HVAC professional to determine the best size and efficiency rating for your home.

2. Optimizing Your Thermostat Settings for Maximum Savings

The thermostat is the control center for your air conditioning system, and setting it correctly can save you money on your energy bills. Here are some tips on how to optimize your thermostat settings for maximum savings.

Set the Temperature Wisely

One simple way to save money on your energy bill is to set your thermostat to a higher temperature when you’re not at home or when you’re sleeping. According to the Department of Energy, turning your thermostat back 7-10°F for 8 hours a day can save you up to 10% on your energy bill annually. Set your thermostat for your comfort level, and drop it a few degrees if you are leaving for work.

Use Programmable Thermostats

A programmable thermostat can make it easier to manage your air conditioning system. You can program it to adjust the temperature automatically when you are away from home or asleep. This means that you won’t have to remember to turn the temperature up or down manually, and you will save money on your energy bills.

Invest in a Smart Thermostat

A smart thermostat takes programmable thermostats to the next level by learning your schedule and adjusting the temperature accordingly. They also adjust the temperature based on the weather and your home’s humidity levels. A smart thermostat can save up to 23% on your energy bill and provide convenient control from anywhere, including your smartphone, tablet, or computer.

By optimizing your thermostat settings, you can save money on your energy bills and reduce the wear and tear on your air conditioning system. Consider these tips when setting your thermostat to maximize your savings.

3. DIY Maintenance Tips to Keep Your AC Running Efficiently

One of the most important tasks of an HVAC system owner is to perform regular maintenance to keep the system running efficiently. This is especially true for air conditioning (AC) systems, as they work tirelessly during the summer season to keep your home cool and comfortable. Here are some simple DIY maintenance tips to help you keep your AC unit running efficiently.

Clean or Replace the Air Filter Regularly

The air filter is arguably the most important component of an AC unit. It helps to trap dust, dirt, and other particles, preventing them from entering the system or blowing into your home. Over time, the air filter can become clogged with dirt, restricting the flow of air into the system and making it work harder to cool your home. This can lead to energy waste and even system failure, if left unchecked.

To prevent this, it is recommended to clean or replace the air filter at least once a month. To clean the filter, remove it from the unit and gently vacuum or wash it with mild soap and water. To replace the filter, refer to your manufacturer’s instructions on how to do so.

Clean the AC Coils

Over time, the AC coils can accumulate dirt, debris, and other particles that restrict the flow of air and reduce the system’s efficiency. To clean them, turn off the power to the system and remove any debris or grass clippings around the unit. Then, carefully brush the coils to remove any dirt or grime. You can also use a coil cleaner and a garden hose to rinse them clean, but be sure not to bend or damage the fins.

Clean the Condensate Drain Line

The condensate drain line is responsible for removing the excess moisture that is produced by the AC unit. If this line becomes clogged with dirt, mold, or algae, it can cause the water to back up and damage your system. To clean the drain line, locate the outside drain pipe and use a wet/dry vac or a pipe cleaner to remove any obstructions.

By performing these simple maintenance tasks, you can keep your AC system running smoothly throughout the summer season, while also saving energy and money in the process.

4. Ductwork Upgrades: How Sealing and Insulation Can Save You Money

How to Save Money with AC?

If your air ducts are not properly sealed or insulated, your AC unit will have to work harder to keep your home cool, leading to higher energy bills. In fact, according to the U.S. Department of Energy, leaky ducts can increase your energy costs up to 30%. By sealing and insulating your ductwork, you can reduce energy waste and save money on cooling costs.

Seal your ducts: Start by inspecting your ductwork for any leaks or gaps. Use foil tape or mastic sealant to seal any leaks that you find. Duct tape is often not sufficient and may degrade over time. Properly sealed ducts not only improve energy efficiency, but also improve your indoor air quality by reducing the amount of dust, dirt, and pollutants that can enter your home through the ducts.

Insulate your ducts: Insulating your ductwork can further reduce cooling costs by preventing your cooled air from warming up as it travels through hot or unconditioned spaces. Common areas to insulate include attics, crawl spaces, and garages. Use insulation with a minimum rating of R-6 for best results. If your ducts are not already insulated, consider hiring a professional to perform the job. Improper installation or insufficient insulation can lead to further issues with your AC system.

By sealing and insulating your ductwork, you can shrink your energy bills, improve your home’s comfort, and extend your AC’s lifespan. These simple steps can make a big difference in your home’s overall energy efficiency and reduce your carbon footprint.
