R22 vs R410a vs R32 —
Which Refrigerant is Best for Nigeria?
A practical guide for Nigerian HVAC contractors, spare parts dealers and importers on the three most important refrigerant grades in Nigeria’s AC market — what they are used for, how they compare, and what you need to stock in 2026.
Written by Al Waleed A/C Spare Parts Trading LLC · Al Rigga, Deira, Dubai
Why this guide exists: Every week, Nigerian HVAC contractors and spare parts dealers WhatsApp Al Waleed asking which refrigerant to stock, which to recommend to their customers, and how R32 fits into a market that still runs heavily on R22. This guide answers all three questions directly — without the marketing language. It is written from the perspective of a Dubai HVAC exporter who has been supplying Nigeria since 2005 and has watched the Nigerian refrigerant market evolve through every transition.
The Nigerian Refrigerant Market in 2026 — Three Generations Running Simultaneously
Nigeria’s AC and refrigeration market in 2026 is unusual globally in one specific way: three refrigerant generations are running simultaneously across a single installed base, and all three will remain active for years. R22 — the first-generation HFC/HCFC that should technically have been phased out — is still the refrigerant in millions of Nigerian split AC units and commercial refrigeration systems installed before 2015 and still in daily service. R410a — the second-generation HFC that replaced R22 from approximately 2012 onwards — is now the dominant refrigerant in all new AC units installed in Nigeria and represents the largest single volume of refrigerant demand. R32 — the third-generation lower-GWP refrigerant now specified in the latest AC models from Daikin, Mitsubishi, Midea, and Gree — is growing rapidly as these brands’ newest models enter Nigeria.
A Nigerian HVAC dealer who tries to serve only one or two of these three generations will lose service jobs to competitors who can cover all three. Understanding the differences between R22, R410a, and R32 — and stocking all three correctly — is the baseline competency for any Nigerian HVAC spare parts business in 2026.
R22 — Still Nigeria’s Highest-Volume Legacy Refrigerant
R22 (chlorodifluoromethane, HCFC-22) was the standard refrigerant in virtually all residential and commercial AC systems installed in Nigeria from the 1990s through to approximately 2014. It is an HCFC — a partially halogenated compound that depletes the ozone layer and is classified as a controlled substance under the Montreal Protocol. Nigeria, as a signatory, has commitments to phase down R22 consumption — but the phase-down does not mean R22 disappears overnight from Nigeria’s service market.
The R22 Situation in Nigeria — Why It Is Still Essential to Stock
Nigeria has tens of millions of R22 split AC units, window AC units, and commercial refrigeration systems that were installed between 1995 and 2015 and are still in active daily service. These units will not be replaced overnight — economic conditions in Nigeria mean that a functional R22 AC unit that simply needs a refrigerant top-up will continue to be recharged with R22 for years, not replaced with an R410a system. The R22 service market in Nigeria is therefore not declining as fast as the global refrigerant phase-down schedule would suggest — it is sustained by the economic reality that refrigerant replacement is far cheaper than equipment replacement for Nigerian households and businesses.
R22 operating characteristics relevant to Nigerian service: operating pressure at Nigerian ambient is lower than R410a — approximately 11–13 bar discharge pressure in normal operation, making R22 gauges and service equipment adequate for the pressure levels encountered. R22 systems use mineral oil or alkylbenzene compressor oil — not POE oil. R22 is a single-compound refrigerant that can be charged as vapour from a cylinder without fractionation risk. WESTRON® and MAXRON® R22 are available from Al Waleed in 1kg and 13.6kg cylinders for Nigeria export.
R410a — Nigeria’s Dominant New-Installation Refrigerant
R410a (a zeotropic blend of R32 and R125 in equal proportions) became the standard refrigerant for new residential and commercial split AC systems in Nigeria from approximately 2012–2015, when Chinese AC manufacturers — who dominate Nigeria’s new unit sales — transitioned their production to R410a systems. All LG, Samsung, Midea, Gree, Haier, Hisense, TCL, and other major brand split AC units installed in Nigeria from this period onwards use R410a.
Critical R410a service points for Nigerian technicians: R410a operates at approximately 60% higher pressure than R22 — discharge pressures of 25–30 bar are normal in Nigerian ambient conditions. This means R22 manifold gauges cannot be used on R410a systems. R410a uses POE (polyolester) oil — mineral oil must never be added to an R410a system. R410a is a blend of two refrigerants and must be charged as a liquid (not vapour) to prevent fractionation — if vapour is drawn from the top of the cylinder, the R32 component evaporates preferentially, leaving a different composition mixture in the cylinder. Always invert the cylinder and charge liquid through the manifold gauge into the low-side during standby or use the liquid service port directly. Charge by weight — not by pressure alone.
R410a demand in Nigeria in 2026 is higher than any other single refrigerant grade — driven by the large and still-growing installed base of post-2015 residential split AC units, ongoing new installation demand, and NEPA’s power cycling that causes refrigerant loss through seal stress in all Nigerian AC systems at a higher rate than in stable grid environments. WESTRON® R410a 11.3kg cylinders are the standard import format for Nigerian dealers from Al Waleed.
R32 — The Growing Third-Generation Refrigerant Entering Nigeria
R32 (difluoromethane) is a single-compound HFC refrigerant with a Global Warming Potential (GWP) approximately one-third that of R410a. It was introduced as the next-generation AC refrigerant by Daikin and subsequently adopted by Mitsubishi, Midea, Gree, and other major AC manufacturers for their latest model ranges. R32 is now specified in a growing number of AC models entering Nigeria — particularly in the premium and inverter segments where these brands are expanding their Nigerian market presence.
R32 Safety — What Every Nigerian Technician Must Know Before Servicing R32 Systems
R32 is classified A2L — mildly flammable. This is a critical safety distinction from R22 (non-flammable, A1) and R410a (non-flammable, A1). R32 will not ignite under normal AC operating conditions, but it can form a flammable mixture with air if released in an enclosed space in sufficient concentration. Nigerian HVAC technicians servicing R32 systems must use R32-rated service equipment (manifold gauges, recovery equipment), must not use ignition sources in enclosed spaces when servicing R32 systems, and must ensure adequate ventilation during refrigerant recovery and charging. R32 uses POE oil like R410a. WESTRON® R32 10kg cylinders are available from Al Waleed for Nigeria export.

What Should a Nigerian HVAC Dealer Stock in 2026?
The answer depends on which segment of Nigeria’s market the dealer serves — but for a dealer serving a mixed residential and light commercial contractor base across Lagos or Abuja in 2026, the practical minimum refrigerant stock is as follows.
R22 in 13.6kg cylinders should represent the largest volume of any single refrigerant grade in stock — because Nigeria’s R22 legacy installed base is still enormous and the service demand is consistent year-round. A dealer who runs out of R22 loses service jobs to competitors in the most active segment of Nigeria’s residential AC market.
R410a in 11.3kg cylinders should be the second-largest stock position — this is the current-generation standard for all post-2015 split AC units and will grow as more of these units enter the service cycle. R410a demand in Nigeria grows proportionally every year as the post-2015 installed base ages and begins to require more frequent service.
R600a in 420g cans should be stocked in case quantities for the domestic refrigerator repair segment — a high-frequency, consistent demand category in every Nigerian city.
R32 in 10kg cylinders should be stocked in smaller quantities — the R32 installed base in Nigeria is still growing and the service demand has not yet reached the volume of R22 or R410a. However, R32 service demand is growing rapidly as more R32 AC units are sold in Nigeria each year. A dealer who cannot supply R32 in 2026 is already losing some service calls — and this gap will widen through 2027 and beyond.
R134a in 13.6kg cylinders covers automotive AC and commercial refrigeration — not a core residential AC grade but a consistent demand from the automotive workshop and cold chain segments that many Nigerian HVAC dealers also serve.
Frequently Asked Questions — R22, R410a and R32 for Nigeria
Can R410a or R32 be used to top up an R22 system in Nigeria?
No — R22, R410a, and R32 are incompatible refrigerants and must never be mixed in the same system. They operate at different pressures, require different compressor oils, and have different thermodynamic properties. Adding R410a or R32 to an R22 system will contaminate the refrigerant circuit, produce incorrect operating pressures, and damage the compressor. An R22 system must always be topped up with R22 — or fully converted to R410a through a complete system replacement (not a simple refrigerant swap, which is not technically sound). There is no legitimate “drop-in” replacement for R22 that can be mixed directly with remaining R22 charge in a working system.
Will R22 become unavailable in Nigeria as the Montreal Protocol phase-down continues?
R22 is being progressively phased down in Nigeria under the Montreal Protocol — but phased down means progressively reducing production and import quotas, not an immediate ban. R22 will remain available for servicing existing equipment in Nigeria for a number of years, though supply will tighten and prices may rise as the phase-down accelerates. Nigerian HVAC dealers should plan for a gradual R22 price increase over the coming years and should be prepared to advise their commercial and institutional clients on R22 equipment end-of-life planning. For domestic residential customers, R22 system maintenance remains practical and cost-effective in Nigeria’s current economic environment. Al Waleed continues to stock and export WESTRON® and MAXRON® R22 for Nigeria while supply remains available.
Do Nigerian technicians need special training or different tools to service R32 systems?
Yes — R32’s A2L mildly flammable classification requires specific service practices that differ from R22 and R410a service. Nigerian technicians servicing R32 systems must use manifold gauges and service hoses rated for R32 (not the same as R410a gauges, though the pressure ranges are similar), use refrigerant recovery equipment rated for A2L flammable refrigerants, avoid any ignition sources in the service area when refrigerant may be present in the air, ensure adequate ventilation in enclosed indoor spaces during service, and be aware that R32’s refrigerant charge weight per system is lower than R410a for the same cooling capacity — charging by weight is especially important with R32. Many refrigerant leak detector devices used in Nigeria are calibrated for HFCs — confirm that the detector responds to R32 before relying on it for R32 leak detection.
