Demystifying HVAC Energy Ratings: Choosing Energy-Efficient Models for Your Home Nov 09, 2025

Understanding HVAC energy ratings can be daunting for many homeowners. However, getting a grasp on these ratings is essential for selecting energy-efficient HVAC systems that can save on energy bills and reduce your environmental footprint. At 17 Degrees A/C and Heating, we aim to simplify this process for our customers. This guide will help you make informed decisions when choosing HVAC systems for your home.

The first step in understanding HVAC energy ratings is to know the key terms used in the industry. Seasonal Energy Efficiency Ratio (SEER) is a crucial rating for air conditioners. It measures the cooling efficiency over a typical cooling season. A higher SEER rating means better energy efficiency. Current standards suggest a minimum SEER of 14 in most regions, but energy-efficient models with ratings of 20 SEER or higher are increasingly popular.

Another important metric is the Annual Fuel Utilization Efficiency (AFUE) rating, which applies to furnaces. The AFUE percentage indicates how much energy the furnace converts to heat and how much is lost outside. For example, a furnace with a 90% AFUE rating uses 90% of the fuel to heat your home, with the remaining 10% lost. Choosing a furnace with an AFUE rating of 80% or higher is ideal for homes seeking energy efficiency.

The Heating Seasonal Performance Factor (HSPF) is the rating used for heat pumps and indicates the system's efficiency during the heating season. A higher HSPF number signifies a more efficient heat pump. Modern energy-efficient models can offer HSPF ratings of 8 or above, making them an excellent choice for reducing energy costs during the winter months.

When considering these ratings, you should also factor in the cost of operation. While higher-rated models usually come with a larger price tag, their efficiency can significantly reduce your energy bills. Calculate the long-term savings potential by comparing the operating costs associated with different SEER, AFUE, and HSPF ratings.

For homeowners aiming to make environmentally conscious choices, investing in HVAC systems with ENERGY STAR certifications is advisable. These models meet strict efficiency guidelines set by the U.S. Environmental Protection Agency, ensuring that they offer exceptional performance while saving energy and reducing greenhouse gas emissions.
