Florida’s heat and humidity are no joke. If your AC isn’t built to handle extreme temperatures, high humidity, and salty coastal air, you’ll likely run into higher energy bills, more breakdowns, and less comfort overall. The key is choosing a system that’s engineered for performance, efficiency, and longevity in Florida’s challenging climate.
Let’s take a look at how to choose the best AC system for Florida, and why brands like American Standard and Rheem continue to stand out.
How to Choose the Best AC System for Florida
1. Start with SEER2 Ratings
Florida homeowners need systems with high energy efficiency due to nearly year-round usage. That’s where SEER2 comes in—the updated national standard that better reflects real-world energy performance. A higher SEER2 rating means lower energy bills and more consistent cooling. For Florida, aim for a unit with a SEER2 rating of at least 15 for balanced cost and performance. Premium systems reach 18+ SEER2, offering optimal efficiency during the peak of summer.
2. Don’t Overlook Humidity Control
Cooling the air is only half the battle in Florida. Humidity can make your home feel warmer than it actually is, leading to discomfort and potential mold issues. Look for AC systems with advanced humidity control features, such as variable-speed compressors, variable-speed air handlers, and built-in dehumidification modes. These systems don’t just cool—they actively manage indoor moisture levels, making your living space healthier and more comfortable.
3. Prioritize Corrosion Resistance
Coastal areas bring salt air, which can quickly corrode standard HVAC components. Even inland, Florida’s high humidity contributes to wear and tear. That’s why the best AC systems for Florida use coated coils, rust-resistant hardware, and durable casing materials. American Standard, for example, offers systems specifically designed to withstand corrosive environments.
4. Choose Smart Thermostat Compatibility
In Florida, energy savings aren’t just about the system—it’s also how you control it. Smart thermostats allow you to automate cooling schedules, track usage, and adjust temperatures remotely. Look for AC systems that integrate with modern smart home platforms. With the right setup, you can optimize your energy use even when you’re not home.
5. Right-Sizing Is Everything
A properly sized AC system ensures your home stays cool without overworking the equipment. Oversized systems can short-cycle (turning on and off too often), while undersized units may struggle to keep up in the peak of summer. A professional load calculation takes into account square footage, insulation, sun exposure, and ceiling height to find the system that’s just right for your home.
6. Ensure Expert Installation
The most important day in an AC system’s life is the day of installation. Even the best AC system can underperform if it’s not installed correctly. Ductwork, airflow, refrigerant levels, and proper calibration all play critical roles. Work with certified professionals who understand Florida’s climate and code requirements. Installation quality directly impacts efficiency, comfort, and system longevity.
7. Look for Warranty Protection
Florida’s weather can be punishing, so long-term reliability matters. Choose systems that come with proven warranties—ideally 10 years or more on parts and compressors. This not only protects your investment but also gives you peace of mind.
Why Rheem and American Standard Stand Out
Both Rheem and American Standard have long reputations for reliability, efficiency, and performance—qualities that Florida homeowners need most.
- American Standard: Known for quiet operation and superior humidity control, their systems feature durable materials that hold up in salty, humid environments. Options like variable-speed compressors and enhanced coil protection are ideal for Florida homes.
- Rheem: Offers some of the most rigorously tested systems in the industry. Their variable-speed units provide excellent temperature precision and energy savings. Many of their models are designed specifically to resist corrosion and perform in extreme heat.
Your Perfect Florida AC System Starts Here
