Why R-454B Refrigerant Is in Short Supply And How It Could Affect Your AC in Miramar Beach, FL
Living in Miramar Beach, FL, means you're no stranger to warm, humid days. The salty breeze, sun-filled skies, and laid-back coastal lifestyle are exactly why people love it here. But with paradise comes a reality we all understand: reliable air conditioning isn't a luxury—it's a necessity.
As local residents know, the Florida heat doesn’t take a break, and neither should your air conditioner. However, recent industry changes are creating ripples that could impact homeowners and businesses alike. One of the most talked-about developments in the HVAC world right now is the shortage of R-454B refrigerant, a newer, eco-friendly refrigerant gaining popularity across the country.
So what exactly is R-454B? Why is it in short supply? And how could it affect your AC here in Miramar Beach? Let’s break it down in simple, understandable terms.
What Is R-454B and Why Is It Important?
R-454B is a refrigerant that’s been introduced as a more environmentally friendly alternative to older types like R-410A, which has been widely used for years. As part of global efforts to reduce greenhouse gas emissions, the HVAC industry is shifting toward refrigerants with lower Global Warming Potential (GWP).
Here’s why R-454B matters:
-
Lower Environmental Impact: R-454B has a GWP of 466—roughly 78% lower than R-410A, which has a GWP of 2,088.
-
Industry Adoption: Many major HVAC manufacturers have already announced that they are phasing out R-410A systems and replacing them with equipment compatible with R-454B.
-
Regulatory Compliance: The U.S. Environmental Protection Agency (EPA) and global environmental accords are pushing for more sustainable refrigerants as part of climate action goals.
In short, R-454B is the future of residential and commercial air conditioning—but that future is hitting a speed bump.
Why Is R-454B Refrigerant in Short Supply?
Several factors have contributed to the limited availability of R-454B in 2025. Let’s take a look at the most significant ones:
1. Sudden Surge in Demand
As more HVAC systems are designed to use R-454B, the demand has skyrocketed. Manufacturers, contractors, and wholesalers are all trying to secure supply, creating bottlenecks.
2. Global Supply Chain Challenges
Refrigerant production relies on a global network of chemical manufacturers, many of which are still recovering from pandemic-era disruptions. In addition:
-
Some raw materials required to produce R-454B remain limited.
-
Shipping delays and freight costs have increased.
-
Regulatory restrictions on chemical plants in countries like China have further slowed production.
3. EPA Phasedown Regulations
Under the American Innovation and Manufacturing (AIM) Act, the U.S. is following a phasedown schedule for high-GWP refrigerants. The latest 2024–2025 step includes a 30% cut in HFC refrigerant production and import levels. This shift has caused refrigerant companies to ramp up R-454B production quickly—but not fast enough to meet growing demand.
4. Limited Manufacturer Output
Unlike R-410A, which had decades to establish production and supply infrastructure, R-454B is still relatively new. Only a few chemical manufacturers currently produce it, meaning any hiccup at one facility can have a ripple effect across the market.
How Does the R-454B Shortage Affect Your AC in Miramar Beach?
Whether you’re upgrading your AC, building a new home, or simply want to stay cool year-round, the R-454B shortage could influence your plans. Here’s how.
1. Delays in Equipment Installation
New systems designed for R-454B are in high demand. If you’re considering replacing an old AC unit, you might experience delays in ordering or installing a new system that uses this refrigerant.
2. Service and Maintenance Impacts
While older units still use R-410A or even R-22, newer installations using R-454B may face service challenges. If a repair involves refrigerant recharge, technicians may struggle to obtain enough R-454B on short notice.
3. Potential for Higher Costs
When supply drops and demand rises, costs typically go up. While we won’t quote specific prices here, you might see elevated costs for systems that use R-454B—or for any HVAC project requiring refrigerant over the next year or two.
4. Limited Retrofit Options
R-454B is not a direct drop-in replacement for R-410A or R-22. That means if your system was not designed for R-454B, converting it would likely be impractical. Your best option is to consult a qualified technician to evaluate your system's compatibility and your best long-term choices.
What You Can Do as a Homeowner in Miramar Beach
Don’t let refrigerant headlines leave you hot under the collar. While supply issues are real, you still have options—and support—when it comes to managing your HVAC system wisely.
1. Schedule Preventative Maintenance
Keeping your current system running smoothly reduces the chances of unexpected breakdowns. A well-maintained unit is less likely to need a refrigerant recharge or urgent replacement.
2. Plan Ahead for Replacements
If your air conditioner is more than 10–15 years old, consider starting the conversation about replacement now—before peak summer demand hits or equipment becomes harder to source.
3. Consult with a Professional HVAC Company
Trying to navigate refrigerant changes and system options alone can be overwhelming. Trust local professionals who stay up to date on the latest industry changes and can recommend the right path forward for your home or business.
4. Ask About Alternative Solutions
Depending on your situation, your technician may be able to offer viable alternatives that meet your cooling needs without being entirely dependent on R-454B availability.
Why the Industry Is Moving Toward Low-GWP Refrigerants
While the current shortage is frustrating, it's part of a larger and important transition. Lower-GWP refrigerants like R-454B play a critical role in reducing the environmental impact of HVAC systems.
According to the EPA, HVAC equipment accounts for approximately 10% of direct greenhouse gas emissions in the U.S. Using refrigerants with a lower GWP is one of the most effective ways to reduce a system’s climate footprint.
In time, the market will adjust. Supply will stabilize. And the shift to cleaner technologies will ultimately result in more efficient, environmentally friendly systems that benefit everyone—from homeowners in Miramar Beach to communities around the world.
What to Expect from the Future of AC in Florida
Looking ahead, expect a few things to continue:
-
Increased adoption of R-454B-compatible systems across the HVAC industry.
-
Further refrigerant restrictions, including more HFC reductions over the next several years.
-
Technology advancements, including systems designed to be more efficient, quieter, and easier to maintain.
In other words, while the refrigerant shortage may cause short-term disruptions, it’s paving the way for better long-term cooling solutions. That’s good news for Miramar Beach residents who value comfort, efficiency, and sustainability.

Why April Is The Best Time To Upgrade Your Air Conditioner in Destin, FL
Destin, Florida, with its warm, humid climate and breezy coastal vibes, is a beautiful place to call home. From sandy beaches to stunning Gulf Coast sunsets, there’s no shortage of outdoor activities to enjoy throughout the year. However, when the summer months roll around, the heat and humidity can make it feel like you’re living in an oven. That’s where your air conditioner comes in.
While it’s easy to forget about your AC system until it’s pushing 90°F outside, taking action early—especially in April—can make all the difference in terms of comfort, cost, and energy efficiency. If you’ve been considering upgrading your air conditioning system, this is the perfect time. Let’s explore why April is the best month to upgrade your air conditioner in Destin, FL, and how it can benefit both you and your home.
The Importance of a Well-Functioning AC System
In Destin, we experience warm weather for most of the year, with average high temperatures reaching into the 80s and 90s from late spring through early fall. These high temperatures make air conditioning not just a convenience, but a necessity. A reliable and efficient AC system can be the difference between comfort and constant frustration during the hotter months.
Over time, even the best AC units can wear down. Whether it’s due to age, frequent repairs, or simply not keeping up with your cooling demands, an outdated system can cause discomfort and lead to increased energy bills. A new, energy-efficient air conditioner can make a world of difference, offering better cooling, reduced energy consumption, and fewer breakdowns.
So, why should you focus on upgrading your AC in April? Let’s break it down.
1. Beat the Summer Rush
If you’ve ever had to schedule an AC repair during the height of summer in Destin, you know how challenging it can be to get an appointment. HVAC professionals are often swamped with emergency service calls, making it harder to get timely service.
By upgrading your air conditioner in April, you avoid the summer rush. You’ll have more flexibility in choosing an appointment time that works for you, ensuring that your system is installed well before the heat arrives. Additionally, HVAC technicians aren’t as busy in the spring, so you’ll likely experience shorter wait times and potentially lower installation costs.
2. Save on Energy Costs with a More Efficient System
Older air conditioners are notorious for their inefficiency. If your unit is more than 10-15 years old, it may be consuming more energy than necessary, leading to higher electricity bills. In fact, according to the U.S. Department of Energy, air conditioners older than 10 years can use up to 60% more energy than newer models.
April is the perfect time to upgrade to an energy-efficient system before the hot weather hits. Modern air conditioners are designed to use less energy while providing superior cooling. Look for systems with high Seasonal Energy Efficiency Ratio (SEER) ratings. A higher SEER rating means better energy efficiency and lower operational costs.
By upgrading in April, you’ll have plenty of time to research the best models and consult with experts to find the most energy-efficient system that suits your home’s needs. The result? A more comfortable home and lower utility bills year-round.
3. Avoid the Stress of Last-Minute Repairs
The last thing anyone wants is for their air conditioner to break down when it’s 95°F outside and you need it the most. Unfortunately, air conditioners don’t always give us a heads-up when they’re about to fail, and trying to repair or replace a broken system in the middle of the summer can be stressful and costly.
Upgrading in April gives you peace of mind knowing your new system will be in place and running smoothly before you need it most. You won’t have to worry about sudden breakdowns or making emergency calls to HVAC technicians who are overwhelmed with work.
4. Enjoy More Affordable Installation Costs
April falls in the "shoulder season" between winter and the peak summer months. HVAC companies often offer discounts or lower prices during this time since there is less demand for services. You may be able to take advantage of promotional offers or rebates on new systems. Plus, with fewer service calls happening, installation costs tend to be more affordable compared to the busy summer months.
This is an excellent opportunity to get a high-quality air conditioning system installed without breaking the bank. It also allows you to allocate more of your budget toward selecting a high-performance unit that can provide long-term savings on energy bills.
5. Prepare Your Home for Maximum Comfort
Spring is a time for cleaning, maintenance, and renewal, making it an ideal time to upgrade your AC system. By scheduling your installation in April, you can ensure that your home will be fully prepared for the warmer months ahead.
A new air conditioner means you can customize your system to your specific needs, ensuring maximum comfort and efficiency. During your consultation, HVAC professionals can assess your home’s cooling requirements, room sizes, insulation, and more. With this knowledge, they can recommend a unit that will keep your entire home cool, rather than wasting energy cooling rooms that don’t need it.
Additionally, upgrading to a new system allows you to take advantage of smart technologies like Wi-Fi thermostats and zoning systems, which can give you more control over your home’s temperature and further increase efficiency.
6. Take Advantage of Manufacturer Warranties
When you upgrade your air conditioner, you not only get the benefits of improved performance but also the peace of mind that comes with warranties and guarantees. Many manufacturers offer limited warranties on parts, compressors, and other components, ensuring that you're covered in case something goes wrong after installation.
Upgrading in April means that your new air conditioner will be covered under warranty throughout the upcoming summer months when it’s working hardest. This coverage gives you extra reassurance that your investment is protected, should any issues arise.
7. Get Expert Advice and Professional Installation
One of the most important aspects of upgrading your air conditioner is choosing the right system for your home. With so many different models, brands, and features available, it can be difficult to know where to start.
A professional HVAC technician can guide you through the selection process, considering factors like the size of your home, your cooling preferences, energy efficiency, and budget. They’ll also ensure that your new system is installed correctly, which is crucial for optimal performance and longevity.
Improper installation can result in lower efficiency, higher energy bills, and potential damage to the system. Upgrading your AC system in April gives you ample time to consult with experts who can ensure your system is installed and functioning properly, so you can enjoy cool, comfortable air throughout the summer.

Retracing your Roots | New London, Connecticut
Air Conditioning & Heating, Inc. and the Emerald Coast of Destin, Florida have deep roots. Owner and President, Kevin Leonard Casey, can trace his ancestry back to his mother’s great grandfather, Destin’s founding father, Leonard Destin.
Leonard Destin, his father (George Destin), and his brother set out from New London, Connecticut with their ships and ran into a hurricane near Cape Canaveral, Florida. Two of the ships (carrying Leonard, his father and brother) were lost at sea. Stories had long circulated in the port of New London about the excellent fishing to be found off the Florida coasts. Leonard Destin decided to continue on and look for the best fishing he could find, as well as a place to settle down.
By the late 1870’s Leonard had built a thriving commercial fishing enterprise and employed many people in the area which was then called East Pass. Destin lived here with his family, consisting of 4 sons and 3 daughters, until his death in 1884.
Recently, Kevin Casey and his wife, Celeste, visited New London, Connecticut to retrace history and research his family tree. Below is their personal photo album from this special vacation. For more information about the Destin family history, click HERE.
How an AC Works
- Evaporator - Cooling coils remove heat and humidity from the air using refrigerant.
- Blower - A blower (fan) circulates air over the evaporator, dispensing the chilled air.
- Condenser - Hot coils release collected heat into the outside air.
- Compressor - A pump that moves refrigerant between the evaporator and the condenser to chill the indoor air.
- Fan - A fan blows air over the condenser to dissipate the heat outside.
- Filter - Located in the air conditioning unit to remove particles from the air.
- Thermostat - A control system to regulate the amount of cool air that is distributed.
