It is difficult to predict how SEER 2 ratings will affect the costs of air conditioners in 2023. SEER 2 ratings are a type of modified SEER rating that takes into account the hottest days of the year, when an air conditioning system is likely to be running at its maximum capacity. These ratings are considered to be more accurate than standard SEER ratings, but they are not as widely used.

It is possible that the use of SEER 2 ratings could lead to higher costs for air conditioners in the future. This is because air conditioners with high SEER 2 ratings are likely to be more efficient than those with lower ratings. As a result, manufacturers may need to invest in technology and materials to improve the efficiency of their air conditioning systems in order to meet the higher standards. This could lead to higher costs for consumers.

However, it is also possible that the use of SEER 2 ratings could lead to lower costs for air conditioners in the future. This is because more efficient air conditioning systems can save energy and reduce utility bills, which can save money for consumers in the long run. In addition, the increased efficiency of air conditioners with high SEER 2 ratings could lead to a longer lifespan for the equipment, which could also save money for consumers.

Overall, the effect of SEER 2 ratings on the costs of air conditioners in 2023 is uncertain. It will depend on a variety of factors, including the adoption of SEER 2 ratings by manufacturers and consumers, and the impact of these ratings on the efficiency and lifespan of air conditioning systems.
