SEER vs EER

When it comes to energy efficiency, there is often lingo that can be confusing to anyone not in the trades industry. So what do these terms mean, and what is the difference? Also, what things should you consider when making a decision that is best for your home? SEER (Seasonal Energy Efficiency Ratio) and EER (Energy Efficiency Ratio) are both measures of the efficiency of air conditioning and heating systems. The key difference is: SEER rating measures the system’s efficiency over an entire cooling season, taking into account variations in temperature and humidity. While EER rating measures the system’s efficiency at a single outdoor temperature (usually 95°F) and a fixed indoor temperature. In summary, SEER considers seasonal variations, while EER measures performance at a specific temperature. All major appliances in your home have EER ratings, however, your heat pump is what will have a SEER rating. When choosing a SEER rating for your system, consider some the following factors. Climate- If you live in a hot and humid climate, a higher SEER rating (16-20) is recommended. Energy efficiency- Higher SEER ratings mean greater efficiency and lower energy bills. Budget- Higher SEER ratings often cost more upfront, but may lead to long-term energy savings. Comfort- Higher SEER ratings can provide better humidity control and a more consistent temperature. Local regulations- Check for minimum SEER ratings required by local building codes or energy standards. Local codes in Jacksonville, FL require a minimum 14.3 SEER. System compatibility- Ensure the SEER rating matches your system’s capacity and components. Noise level- Higher SEER units may operate quieter. Another bonus, many utility providers offer rebates when having a higher SEER rated system installed in your home, as this eases some of the burden on the amount of electricity used to operate it. These rebates typically start at 16 SEER, depending on the electrical provider. However, to receive these rebates, you must used a licensed contractor like Ideal Conditions and have the job permitted and inspected.
