2025 is shaping up to be a milestone year for sustainability in the UAE. With new climate laws coming into effect after COP28, businesses and residents alike are being pushed toward greener HVAC solutions. For the Middle East, this isn’t just about ticking regulatory boxes—it’s about managing cooling efficiently under extreme desert heat while reducing carbon impact. AlFaisalHVAC.com is helping UAE technicians and building managers transition smoothly, supplying eco-friendly refrigerants and the tools needed to handle them safely.
The Regulatory Push: UAE’s Commitment to Sustainable Cooling
The UAE has doubled down on sustainability with a suite of regulations targeting the cooling sector. Two key drivers are:
- The Kigali Amendment: Mandates a global phase-down of high-GWP refrigerants like R410A.
- UAE National Cooling Plan & 2025 Climate Laws: Require corporate carbon reporting and energy efficiency compliance.
What this means for building owners and technicians is simple: your refrigerant choice now affects compliance and operational cost. Choosing low-GWP alternatives isn’t optional; it’s a legal and economic necessity.

Top Eco-Friendly Refrigerant Candidates for the Gulf
Cooling in the Gulf isn’t easy. Temperatures regularly exceed 50°C, and humid conditions can push systems to their limits. Here’s a breakdown of the most promising low-GWP refrigerants suited for these conditions:
R32: The Current Market Leader for Efficiency
R32 has quickly become the go-to choice in Dubai and Abu Dhabi. Why?
- Low GWP: About 66% lower than R410A, reducing environmental impact.
- High Performance: Handles desert heat efficiently, maintaining strong cooling even at 50°C+.
- Energy Savings: Higher EER/SEER ratings mean lower DEWA bills for homes and offices.
In real installations, switching an R410A system to R32 can reduce electricity usage noticeably, especially in high-rise buildings where AC units run non-stop.

Hydrofluoroolefins (HFOs): The Next Generation
HFOs, like R1234yf and R1234ze, are emerging for high-tech applications:
- Ultra-low GWP: Less than 1, making them extremely eco-friendly.
- Applications: Common in chillers, commercial systems, and automotive AC.
- Future-ready: Designed for strict carbon reporting requirements and energy optimization.
While HFOs are still niche in Dubai residential AC, they are gaining traction in large-scale commercial and industrial projects.

The Return of Natural Refrigerants (CO2 and Ammonia)
Natural refrigerants like R744 (CO2) and R717 (Ammonia) are finding their way back into industrial cooling:
- CO2: Used in district cooling, supermarkets, and cold storage. Excellent for large-scale applications due to non-flammability and efficiency.
- Ammonia: Powerful industrial refrigerant for warehouses and processing plants, though it requires specialized safety protocols.
Natural refrigerants offer long-term sustainability, but installation and maintenance require experienced technicians and proper safety measures.

Challenges of Innovation: Handling “Mildly Flammable” A2L Gases
Many eco-friendly refrigerants, including R32, are classified as A2L (mildly flammable). This introduces new safety challenges:
- Specialized tools: Vacuum pumps, leak detectors, and manifolds must be rated for A2L gases.
- Technician training: Only certified technicians should handle these refrigerants to prevent accidents.
- Building considerations: Proper ventilation and leak detection protocols are critical, especially in tight residential spaces.
For example, in Dubai high-rises, rooftop units must be serviced carefully to avoid accidental ignition when charging R32.

Impact on Energy Efficiency and DEWA Bills
Switching to eco-friendly refrigerants isn’t just about sustainability—it directly affects your wallet. Systems charged with R32 or HFOs typically achieve:
- Higher EER/SEER ratings, meaning more cooling per kWh consumed.
- Lower DEWA bills, especially for offices and villas running AC 8–12 hours a day.
- Reduced maintenance stress, since modern refrigerants are less likely to degrade system components.
In real-world testing, property managers have seen 5–10% energy savings just from switching refrigerants while keeping the same compressor and fan setup.

FAQ Section
Is R32 refrigerant illegal in the UAE?
No. R32 is fully legal in Dubai and Abu Dhabi, but it must be handled by certified technicians due to its mildly flammable classification.
What is the GWP limit for new AC systems installed in Dubai in 2025?
The UAE is aligning with Kigali Amendment targets. For residential systems, GWP should be significantly lower than R410A, with most new units using R32 or comparable low-GWP alternatives.
Can a standard technician handle A2L refrigerants like R32 and R454B?
Only trained and certified technicians can handle A2L refrigerants. Regular HVAC personnel without certification should not attempt charging or repairs.
Do eco-friendly refrigerants require different copper piping?
Not necessarily, but you should verify compatibility. Some low-GWP gases operate at slightly higher pressures, so pipe wall thickness and insulation may need adjustment.
How does the UAE’s National Refrigerant Registry track gas usage?
All refrigerant purchases are logged in the National Registry, ensuring compliance with carbon reporting and phase-down targets.
Are natural refrigerants like Propane (R290) used in Dubai homes?
R290 is mostly used in small commercial appliances or industrial units. It’s less common in residential AC due to flammability concerns.
Will switching to an eco-friendly AC unit really lower my electricity bill?
Yes. Modern low-GWP refrigerants like R32 improve energy efficiency, translating to noticeably lower DEWA bills, especially during long summer months.
Summary
2025 marks a turning point in UAE HVAC, with eco-friendly refrigerants, strict climate laws, and smarter technology reshaping the industry. Transitioning to R32, HFOs, or natural refrigerants is no longer just an environmental choice—it’s about compliance, safety, and energy savings.
