The Benefits of Choosing a Higher SEER2 HVAC System

High-Efficiency Air Conditioners Are Better Suited for Certain Homes

When replacing your cooling system, you’ll likely come across unfamiliar terms, including SEER2 rating. While it may seem like technical jargon, a SEER2 rating is worth understanding because of how it affects an air conditioner’s performance, efficiency, and cost.

What Is a SEER2 Rating?

SEER, which stands for Seasonal Energy Efficiency Ratio, measures how efficiently a cooling system – like an air conditioner or heat pump – operates. It’s calculated by dividing the total heat removed during the cooling season by the electricity used to do so.

Starting on January 1, 2023, SEER2 replaced SEER as the new standard for HVAC energy efficiency, using the M1 blower testing procedure to better simulate real-world conditions. The updated SEER2 calculation, mandated by the Department of Energy (DOE), aims to provide a more accurate measure of a system's efficiency by increasing the external static pressure during testing.

Homeowners may come across SEER2 ratings such as 14.3, 15.2, 16, or 18. The DOE requires homes in the North to have a unit with a minimum rating of 13.4, while split-system air conditioners in the Southeast and Southwest require a 14.3 or higher.

Although some systems reach SEER2 ratings in the 20s, a 16 SEER2 model often strikes the best balance between performance and price. However, homes that require year-round cooling may benefit from an even higher rating.

The Benefits of Upgrading to a Unit with a Higher SEER2 Rating

Improved Energy Efficiency

Since cooling systems with greater SEER2 ratings are more energy efficient, they use less energy to reach a home’s desired temperature.

Energy Savings

Improved efficiency and energy savings go hand in hand. Upgrading to a 16 SEER 2 unit or more can save on monthly cooling costs. Savings depend on factors such as the exact SEER2 rating, your home’s size, local climate conditions, and your overall energy usage patterns.

Better Comfort

Many higher-rated SEER2 air conditioners use variable-speed compressors that run more frequently at lower, consistent speeds. This creates steadier temperatures throughout the home by eliminating hot and cold spots. Longer cycles also pull more moisture from the air, balancing humidity levels and making your home feel less moist or sticky.

Quieter Operation

Advanced features such as variable-speed technology and enhanced insulation contribute to a smoother and quieter performance. You also won’t hear the fan and compressor cycling on and off as frequently since the system runs longer intervals.

Incentives

Air conditioners with higher SEER2 ratings may be eligible for federal or state tax credits or utility rebates which can help offset some of the cost.

Lower Environmental Impact

Energy-smart air conditioners consume less electricity to achieve the same cooling output, reducing greenhouse gas emissions. Additionally, these systems use eco-friendly refrigerants that further reduce their environmental footprint.

Is a Higher-rated SEER Air Conditioner Right for You?

Despite their benefits, air conditioners with greater SEER2 ratings are not for everyone. The best choice for your home depends on your budget, local climate, and long-term energy-saving goals.

• Budget: High-efficiency units can be significantly more expensive than air conditioners that only meet minimum requirements, making them less ideal for those on tighter budgets. However, you can still save on energy bills by choosing a system with a minimum 13.4 or 14.3 SEER2 rating, especially if your old AC has a SEER rating of just 10-12.
• Climate: The larger upfront cost of an HVAC unit with a substantially higher SEER2 rating may not be worth it in colder regions where you only use your air conditioner for a few months out of the year. Installing a system with a rating of 16 or higher is more beneficial for homeowners in southern states like Florida and Texas where cooling seasons are longer and humidity levels are higher.
• Savings Goals: Your personal energy goals make a difference. Maybe you’re looking to save more on monthly bills, or you’re focused on using less energy overall. Either way, knowing your priorities helps you choose the system that fits your home best.
