Estimating the potential energy and cost savings of a new air conditioner purchase is now quick and easy with a SEER savings calculator.

In this article, we’ll provide an overview of SEER and SEER2 ratings and how they impact efficiency. We’ll discuss the key features to look for in an accurate SEER savings calculator. You’ll learn how to use a calculator to estimate energy savings for your home based on factors like size, climate, and electricity rate. We’ll also cover regional minimum SEER standards and available utility rebates. Read on to make the most informed decision when it’s time to replace your old AC unit!

An Overview of SEER to SEER2

SEER, Seasonal Energy Efficiency Ratio, is a widely recognized metric used to determine the efficiency of heat pumps and air conditioning systems, during the cooling season. As technology advances, we’re also seeing a transition from traditional SEER ratings to a SEER2 rating, promising an array of potential SEER savings.

What Is SEER?

SEER is a ratio of the cooling output of an air conditioning unit or heat pump during a typical cooling season, divided by the total electrical energy input during the same period. The higher the SEER rating, the more efficient the system is in converting electricity into cooling power. SEER ratings typically range from 14 to 25. Higher SEER ratings indicate greater energy efficiency and potential cost savings. However, many older air conditioning systems operate at much lower SEER ratings due to the original design and efficiency losses from years of use.

What Is SEER2?

SEER2, Seasonal Energy Efficiency Ratio 2, is a metric used to measure the extent to which air conditioning systems are energy efficient. The metric evaluates the cooling output provided by the system over a typical cooling season, divided by the total electric energy input during the same period. SEER2 is an enhanced version of the original SEER metric. This version offers a more accurate representation of a system’s efficiency by taking into account various factors, such as climate, temperature fluctuations, and operating conditions. A higher SEER2 rating means a system is more energy efficient and cost-effective. The rating is a valuable consideration for consumers looking to optimize their energy consumption and reduce utility costs.

Using the SEER to SEER2 Calculator for Optimal AC System Performance

One of the key elements in optimizing your cooling system’s performance has to do with its SEER. If you haven’t given much thought to your air conditioner’s SEER rating, it’s time you did. Here’s where the SEER to SEER2 Calculator comes into play. The tool is designed to make your life easier by providing tangible insights on how to enhance energy efficiency.

Key Features of a SEER to SEER 2 Calculator

A SEER to SEER2 Calculator is not just your average savings calculator. It’s a tool specifically designed to help homeowners and HVAC professionals calculate the energy cost savings when upgrading from an older AC system to a more energy-efficient model with a higher SEER rating. With the SEER to SEER2 Calculator, you can effectively compare the SEER ratings of two air conditioners and calculate the possible savings. Let’s dive deeper to explore some of the key features of this unique tool.

1. SEER Rating Comparison: This feature allows you to enter the SEER ratings of two AC systems: Your current one and the one you plan to upgrade to. Then, it calculates the percentage of energy saved when switching from the SEER to the SEER2 system.

2. Energy Cost Calculation: You can also figure out your energy cost savings. The SEER energy savings calculator uses your annual cooling hours, energy cost per kWh, and the size of your AC system to provide an estimate.

3. Sizing Guide: The SEER energy savings calculator tool offers a sizing guide for your heat pump or AC system based on your house’s square footage. Making sure you have the correctly sized air conditioner is key to ensuring your system runs efficiently.

Potential Cost Savings from Upgrading to a Higher Efficiency SEER2 Air Conditioner

Upgrading from an older, less efficient air conditioner to a new higher SEER2 rated system can provide significant energy and cost savings for homeowners. For example, replacing an old 10 SEER unit with a new 16 SEER2 unit in a 2000 sq. ft. home could save approximately $200 per year, assuming 12,000 BTU cooling output, 1000 kWh of annual energy use, and an electricity rate of $0.12/kWh. The new AC unit would use around 600 kWh annually, compared to 1000 kWh for the older unit. At $0.12/kWh, that equates to $720 per year for the 10 SEER unit and $520 for the new 16 SEER2 unit – a $200 savings. Actual savings will vary based on unit size, efficiency gain, local utility rates, and more – but upgrading to a higher SEER2 almost always pays off over time.

Regional SEER Standards and Requirements

In the climate of Ohio and the Cincinnati region, the federally mandated minimum SEER rating for new air conditioner installations is 13.4 (14 SEER2). However, many homeowners can benefit from upgrading to more efficient systems with SEER ratings of 15, 17, or 20, which can provide energy savings on summer cooling costs. Some local electric utilities in our area offer attractive rebates for installing new air conditioner and heat pump systems that meet higher efficiency standards. For example, Duke provides a $1,250 rebate for a new air conditioner with a SEER of 16 or greater. Checking for available utility rebates and incentives can help offset the upfront cost of installing a more efficient system. Partnering with qualified local HVAC companies that properly size and install new units is key to maximizing energy savings.

Proper Installation Is Key for Maximum Efficiency

When upgrading your air conditioning unit to a higher SEER2 rating, it’s important to remember that the rated efficiency depends heavily on proper installation. Factors like improper refrigerant charging, duct leaks, improper airflow, and poor insulation can greatly reduce the operating efficiency of even the highest-rated AC equipment. Work with reputable, experienced HVAC installation professionals and ask that they follow best practices like duct sealing, manual J load calculations, careful refrigerant charging, and commissioning tests. A 16 SEER2 unit installed poorly may operate like a 13 SEER unit. Investing in quality installation is just as important as investing in a high efficiency AC itself when it comes to energy savings and comfort.

How do you calculate SEER2?

To calculate SEER2, divide the total cooling output of an air conditioning system during a typical cooling season by the total electric energy input during the same period. This formula takes into account the operating conditions over an entire cooling season to determine the energy efficiency of the system. SEER2 is often used as a metric to compare the energy efficiency of different air conditioners and help consumers make informed decisions when purchasing cooling systems.

What is SEER vs SEER2?

SEER (Seasonal Energy Efficiency Ratio) is a metric developed by AHRI to measure air conditioner efficiency as the ratio of cooling output to energy consumed. The updated SEER2 accounts for more variables to better represent system efficiency over an entire cooling season.

How much will I save with a higher SEER rating?

Exact savings from a higher SEER air conditioner depend on many factors, but generally a higher SEER rating can save 10-30% on cooling costs over time compared to lower efficiency models. Minimum SEER standards vary by region, with northern states requiring 14 SEER (13.4 SEER2) and southern states requiring 14 SEER or higher.
