Decoding SEER Ratings: A Key Factor in HVAC Efficiency

At Carden Heating & Cooling, we believe that an informed customer is a satisfied customer. That’s why we’re diving into the technical details of SEER ratings and their significance in today’s HVAC systems.

What is SEER?

SEER stands for Seasonal Energy Efficiency Ratio. It’s a measure of an air conditioning system’s cooling output during a typical cooling season, divided by the total electric energy input during the same period. In simpler terms, it tells you how efficiently your AC unit operates.

Why SEER Matters

Higher SEER ratings indicate greater energy efficiency, which translates to:

• Lower energy bills
• Reduced environmental impact
• Improved comfort in your home
• Potential eligibility for energy rebates

SEER Ratings Explained

Current minimum SEER ratings mandated by the U.S. Department of Energy vary by region:

• Northern states: 13 SEER
• Southern states: 14 SEER
• Southwestern states: 14 SEER for single-phase systems, 12.2 SEER for 3-phase systems

However, high-efficiency units can reach SEER ratings of 20 or higher.

Calculating Energy Savings

To estimate potential savings when upgrading your system, use this formula:

(1 – (Old SEER / New SEER)) x 100 = Percentage of energy savings

For example, upgrading from a 10 SEER to a 16 SEER system could result in a 37.5% reduction in cooling costs.

Beyond SEER: Other Factors to Consider

While SEER is important, it’s not the only factor in HVAC efficiency. Consider:

• Proper sizing of the system
• Quality of installation
• Regular maintenance
• Insulation and ductwork condition
