More and more, professionals are relying on SEER vs. SEER2 measurements to determine (Seasonal Energy Efficiency Ratios) the effectiveness of HVAC systems. As heat waves become more prominent, using AC systems that minimize energy usage will prevent the effects of global warming and reduce utility costs for homeowners and renters.
According to the 2015 U.S. Residential Energy Consumption Survey approximately 76 million homes use central air conditioning equipment, while 13 million homes use heat pumps for heating and cooling. These staggering numbers emphasize the importance of selecting systems that prioritize higher SEER vs. SEER2 values.
Understanding SEER
AC efficiency is measured by how well a system cools in a given space and the amount of electricity needed to do so. SEER is an efficiency ratio calculated by dividing the total cooling output by the total energy consumed by the system during the same period (i.e., warm season). so, to compute this value, there are precise assessment protocols.
SEER ratings are generally higher because most systems are more efficient at cooling than heating. And the measurement only takes the cooling efficiency into account.
As a result SEER has been prevalent in the industry, as it is considered the standard form of measurement.
What is SEER2?
SEER2 refers to the amount of energy consumed for your heating and cooling system over an entire year to evaluate overall equipment performance. Its numerical value is based on the total heat removed from the conditioned space during the annual period divided by the electrical energy consumed by the AC or heat pump.
While SEER has been a dominant force in decision-making for HVAC systems in the past, these qualifications have recently changed.
As of January 1, 2023, all new units produced must be SEER2 compliant. These new standards specify that there must be a minimum of 14 for SEER on all new systems (14.3 SEER2 equivalent), and 15 SEER for the southern United States.
As a result, testing protocols have been developed to provide a better understanding of how systems operate under real conditions. For example, it includes updated criteria for:
- Minimum air handler static pressure,
- Coil-only units’ fan power
- Heat load calculations
- Heating modes
- Variable speed factors
- Off modes
How To Select An HVAC System Based On SEER2
Selecting the right unit based on SEER vs. SEER2 requires additional knowledge regarding HVAC systems that perform according to those standards.
To choose the best AC for your home, it’s best to consider modern air conditioners based on SEER2 criteria. Essentially, new units are increasingly using two-speed or variable speed technology to improve efficiency.
Traditional single speed ACs operate at a fixed speed, regardless of the temperature outside. In other words, this is not ideal for maximizing efficiency.
Although they are the most economical option for those on a fixed budget, they do not function as well as their counterparts, offering less comfort in extreme temperatures. As global warming has become more problematic in southern states, like Florida, this may not be beneficial long term.
In comparison, two-speed ACs operate on two speeds, the high setting for hot days and the low for moderate days. Similarly, variable-speed ACs have a variety of adjustable speeds that can be altered based on outdoor temperature.
When selecting a new system, it’s best to consider not just your initial costs for installation, but also future costs. The benefit to doing so is cutting your current costs in half.
