If you have shopped for a new air conditioning system recently in Melbourne, FL, you have probably noticed a new efficiency rating called SEER2. As of January 2023, the Department of Energy replaced the old SEER rating system with SEER2, and it affects what equipment you can legally install in Florida.
At Inlet Mechanical, we help Brevard County homeowners navigate these changes every day. Here is what you need to know about SEER2 and how it impacts your next AC purchase.
SEER2 Rating Florida: SEER vs SEER2: What Changed
SEER stands for Seasonal Energy Efficiency Ratio — it measures how efficiently an air conditioner converts electricity into cooling over an entire cooling season. The higher the number, the more efficient the unit.
SEER2 uses the same basic concept but tests equipment under more realistic conditions. The new testing procedure uses higher external static pressure to better simulate real-world ductwork resistance. This means SEER2 numbers are typically about 4.7% lower than the equivalent SEER rating.
A unit that was rated 16 SEER under the old system might be rated approximately 15.2 SEER2 under the new system. The actual efficiency of the equipment has not changed — only the way it is measured and reported.
Florida Minimum Requirements
Florida falls in the Southeast region for federal efficiency standards. As of 2023, the minimum requirements for new AC installations in the Southeast are:
Split system air conditioners must meet a minimum of 15 SEER2 (equivalent to the old 16 SEER). Heat pumps must meet a minimum of 15 SEER2 for cooling and 7.5 HSPF2 for heating. Package units have slightly lower minimums at 14 SEER2.
These are the minimums — not what we typically recommend for Melbourne FL homes. Given that Florida air conditioners run 8-10 months per year, the energy savings from a higher-efficiency unit pay for themselves faster here than in most other states.

Frequently Asked Questions
When should I call a professional about seer2 rating florida?
You should call a licensed HVAC professional when you notice unusual performance, higher-than-normal energy bills, strange noises or odors, or any signs of leaks or moisture. In Brevard County, FL, Florida’s heat and humidity can accelerate wear on systems, making prompt attention to issues especially important. Call Inlet Mechanical at (321) 723-0858.
How does Florida’s climate affect seer2 rating florida?
Florida’s combination of high heat, humidity, and salt air (for coastal areas) creates unique demands on HVAC systems. Equipment works harder and longer than in milder climates, accelerating wear on components. Regular professional maintenance adapted to these conditions is essential for reliability and longevity in Brevard County, FL.
Does Inlet Mechanical handle seer2 rating florida for both residential and commercial properties?
Yes, Inlet Mechanical serves both residential and commercial customers throughout Brevard County, including Melbourne, Palm Bay, Cocoa, and surrounding communities. We hold Florida Mechanical HVAC License CMC1250858 and Florida Plumbing License CFC1433105. Call (321) 723-0858 to schedule service.
What SEER2 Rating Should You Choose for Brevard County
For most Melbourne and Palm Bay homes, we recommend 16-18 SEER2 as the sweet spot for balancing upfront cost with long-term energy savings. In a typical 2,000 square foot Florida home, upgrading from a 15 SEER2 to a 17 SEER2 system can save $200-$400 per year on electricity.
Ultra-high efficiency units rated 20+ SEER2 exist, but the additional cost often takes 10-15 years to recoup in energy savings. These units make more sense for larger homes over 3,000 square feet or households that keep the thermostat below 72 degrees year-round.
The efficiency of your ductwork also matters significantly. Even a 20 SEER2 unit will underperform if your ducts leak, are poorly insulated, or are incorrectly sized. Before investing in a high-efficiency system, have your ductwork inspected. We regularly find that sealing and insulating existing ducts improves overall efficiency by 15-25% — regardless of the equipment rating.
Several utility rebates and federal tax credits are available for high-efficiency AC installations. FPL and other Brevard County utilities often offer rebates of $150-$500 for qualifying SEER2 equipment. The federal Energy Efficient Home Improvement Credit allows up to $2,000 in tax credits for qualifying heat pump installations.
