AC Systems and the Energy Star Label

Jun 12, 2023

What is Energy Star and what does it have to do with your air conditioner? Whether you want to learn more about your current AC system or you're in the market for a new air conditioner, take a look at what homeowners need to know about energy efficiency and the Energy Star standard.

What Does the Energy Star Designation Mean?

You can find Energy Star labels on air conditioners and other appliances that use energy (electricity) as a fuel source. This symbol is only on products that meet the U.S. Environmental Protection Agency's (EPA) energy efficiency guidelines. According to the Energy Star website, central air conditioning systems that meet these EPA standards have a higher energy efficiency ratio (EER) and seasonal energy efficiency ratio (SEER) than other cooling appliances.

How Much Electricity Do AC Systems Use?

The answer to this question depends on a few factors. These include the type of cooling system (central AC, mini-split ductless systems, or window air conditioners), the age of the air conditioner, how much you use it, the temperature you set the system to reach, the amount of wear on the system, the quality of the system, the installation, the size of the system, and the climate you live in.

Each year, Americans spend nearly $29 billion on electricity to power AC systems, according to the U.S. Department of Energy. This equals six percent of all the electricity the United States produces annually. Even though your electricity bills aren't in the billions, your share of energy use could take up the bulk of your household's utility budget. This makes choosing an energy-efficient (and Energy Star) cooling appliance important.

Do Energy Star Air Conditioners Really Use Less Electricity?

Yes, Energy Star-certified systems do use less electricity than conventional (non-certified) air conditioners. Not only does the higher efficiency level help the environment (by using fewer natural resources to create and distribute electricity), but it can save you money on utility bills and may even extend the life of your new air conditioner. The less energy your system uses, the lighter the workload. This can decrease wear and tear and reduce the risks of damage.

How Do You Know If You Have an Energy Star Cooling Appliance?

Look for the Energy Star symbol on the outside of your air conditioner. If you're not sure whether your existing unit is Energy Star–certified or if the criteria have changed over the years (for older AC systems), talk to a professional. A qualified, licensed HVAC contractor can help you to learn more about your system's energy efficiency.

Are Central AC Systems the Only Energy Star Cooling Options?

No, central systems are not the only cooling products that could meet the EPA's Energy Star standards. Window units and ductless mini-split air conditioners can also have the Energy Star designation.

Which Energy Star Cooling Product Is the Best Choice?

There isn't one best Energy Star–certified air conditioner for every household. If you're in the market for a new cooling system, the first step is to learn more about which type of unit best matches your home's needs. While a new central system is ideal for homes with air ducts, this type of air conditioner won't work well if you have radiator heat.

If your home doesn't already have ducts and you don't want to pay extra for this type of upgrade, a mini-split ductless air conditioner is an option to explore. These appliances are available in Energy Star–certified models and will not require the contractor to break through walls or install a labyrinth of air ducts throughout your home.

When It's Time To Say Goodbye: Signs That You Need To Replace Your Heating System

16 Feb, 2024

As the temperatures begin to drop, your heating system becomes essential to maintaining your home's comfort. But what if your heating system is struggling to keep up? Should you repair it or replace it entirely? It's a common question among homeowners, and the answer isn't always straightforward. In this blog post, we will discuss the signs that your heating system may need to be replaced instead of repaired. By knowing these signs, you'll be able to make an informed decision about whether it's time to say goodbye to your old heating system. Your Heating System is Over a Decade Old One of the most significant signs that your heating system may need to be replaced is its age. Generally, heating systems have an average life span of about a decade and a half. Beyond that point, your heating system's efficiency will start to decline, and it will likely start to require more frequent repairs. If your heating system is over a decade old, it may be time to consider a replacement. Your Heating Bills are Skyrocketing A sudden and significant increase in your heating bills could be a sign that your system is struggling to keep your home warm. Older systems are less energy-efficient, and as they age, they require more energy to function correctly. If you've noticed that your energy bills are significantly higher than usual, it may be time to replace your heating system with a newer, more energy-efficient model. There's a Strong Odor Coming from Your Heating System If you notice a strong odor coming from your heating system, it could be a sign of a potentially dangerous problem. A smell like rotten eggs could indicate a natural gas leak, while a musty smell could mean your ductwork has mold or mildew growth. Either way, you should have your heating system inspected by a professional immediately. Depending on the severity of the issue, it may be more cost-effective to replace your system entirely. Your Heating System is Making Strange Noises If your heating system is making strange noises like banging, popping, or screeching, it's likely that something is wrong with the system. These noises could be a sign of a range of issues, including a faulty blower fan, a clogged air filter, or a loose part. Some of these problems can be repaired, but if your heating system is making a persistent, loud noise, it may be time to replace it. Your Home is Not Heating Consistently If you're having trouble maintaining a consistent temperature throughout your home, even after repairs or maintenance, it could be a sign of a failing heating system. If you've noticed cold spots in your home or fluctuating temperatures from room to room, it may be time to replace your heating system with a new, more efficient model. A new system can heat your home evenly and consistently, providing you with the comfort you need during the cold winter months. If you've noticed any of the signs we've discussed in this blog post, it may be time to replace your heating system instead of repairing it. While replacing your heating system can be a significant investment, it can also provide you with increased energy efficiency and cost savings in the long run. A new system can also provide you with the peace of mind of knowing that your home is safe and comfortable all winter long.
