A refrigerant recovery machine, known also as a vapor recovery machine, is a device used to safely remove refrigerant from an air conditioning system in an eco-friendly manner. The best refrigerant recovery machine will reduce work time and requires little supervision.
Cooling systems work by compressing a refrigerant, and then sending it through a condenser. It then flows through an expansion valve, which drops its pressure. The refrigerant draws heat from the evaporator which draws heat from the region that is to be cooled. It is then sent back to the compressor to start the cycle over (Source).
If released into the atmosphere, refrigerants can be dangerous. They are toxic to humans, will pollute the environment, and can even deplete the earth’s ozone layer. Refrigerant recovery machines work by drawing in and condensing the refrigerant for safe storage in a cylinder (Source).
These machines are essential tools for working on air conditioning units and several other appliances that require some type of refrigerant. Before you buy a refrigerant recovery machine, consider the price, size, recovery speed, and how many refrigerants the unit can handle. You should also consider its reliability and ease of operation.
In this review, we will examine the top-rated refrigerant recovery machines. All of the machines in this review will help you recover refrigerant, whether you’re a homeowner who is gearing up for a DIY air conditioning replacement or you’re a professional HVAC technician adding to a growing list of tools.

How Does A Refrigerant Recovery Machine Work?
You already know that a refrigerant recovery machine can help to recover the dispersed refrigerant before it gets into the environment and damages it.
The working of a refrigerant recovery machine is quite simple. Think of it as a filtering box, whose inlet valve is connected to a discharge tube. The other end of the pipe is connected to the discharge valve of the air conditioning unit.
In between the two connections, an electronic gauge is also connected, which keeps checking on the pressure and temperature of the air conditioning system.
Another discharge tube is connected to the outlet valve of the refrigerant recovery unit. Additionally, this tube’s end is connected to a refrigerant recovery tank.
Some people also add dryers and filters between the tubes to lower the pressure on the recovery units. However, that unit is optional if your usage for the machine is not that much.
Upon opening the valves, and starting the power supply to the HVAC recovery unit, the high pressure from the air conditioner causes the refrigerant the transfer to the recovery unit through the gauge.
The process is similar to a vacuum action, as the recovery unit sucks the refrigerant out of the HVAC system and stores the liquid in the refrigerant tank.
What You Should Know Before Buying a Refrigerant Recovery Machine
Buying the best refrigerant recovery pump depends on a number of factors. This includes the weight of the recovery unit, its portability, and its inbuilt recovery speed.
You may also want to check on the cost as well as the ease of operating the unit.
Below are some things you’ll want to consider prior to buying a refrigeration recovery machine:
The lighter the refrigerant recovery unit, the easier it is to transport. A lightweight recovery unit is also easy to get to hard-to-reach areas like on ceilings and rooftops.
As technology advances, manufacturers of refrigerant recovery pumps are continuously finding new ways to fit all necessary features into a compact design.
How light or heavy the refrigeration recovery machine also depends on the area of application. The heavy-duty AC recovery units have more weight since they pack advanced additional features that can reduce operation time by half.
Meanwhile, lightweight recovery units have fewer features and are ideal for small-scale jobs.
How heavy a recovery machine determines how portable it will be. Going with the lightest refrigerant recovery unit means you have to sacrifice on a few features. The best way to choose between lightweight or heavy depends on the area of application.
Consider a lightweight refrigerant retrieval machine if you need one for residential application. Such portable recovery units are also easier to carry up roofs or attics to access the AC system.
Meanwhile, the heavier recovery units, also with more features, would be ideal for industrial and commercial applications. They can perform several tasks at once allowing the technician to work firster and more efficiently.
Single Cylinder vs Twin Cylinder
Refrigerant recovery machines with twin cylinders are more efficient and take less time to perform a task. However, they tend to be more expensive and heavier to carry around.
On the other hand, single-cylinder recovery units are slower but more affordable. They are also lightweight and more portable.
Refrigerant recovery units with faster recovery speeds are handy where time is of the essence. A refrigerant recovery machine that features twin-cylinder units will recover faster compared to those with one cylinder installed.
Refrigerant recovery units with faster recovery speeds have the ability to handle more than one task.
Oil-based or Oil-less
Modern recovery units are switching from oil-based to oil-less compressors to boost efficiency. Oil-less recovery units are also cleaner to run compared to those with hermetic compressors.
The more features a refrigerant recovery machine has, the more it will cost on the market. Lightweight recovery units cost less because they contain the basics for performing non-demanding tasks.
Meanwhile, larger refrigerant recovery units are designed to handle more workloads. Such machines will have plenty of inbuilt features to facilitate their efficiency.
FAQs About Refrigerant Recovery Machines
Q: What Is a Refrigerant Recovery Machine?
A refrigerant recovery machine removes the refrigerant from cooling equipment such as freezers, refrigerators, and air conditioners in accordance with EPA standards. DIY enthusiasts or technicians use the machines during the repair or maintenance of these devices.
Q: Do I need a refrigerant recovery machine?
Refrigerant recovery machines are essential because they minimize the leaking of refrigerants into the atmosphere. They recover it in a tank for reuse or recycling.
Q: Why is it important to recover refrigerant?
Refrigerant recovery lessens environmental damage and helps you be more cost-effective as well.
Q: Why is it dangerous for refrigerant to escape into the atmosphere?
Escaped refrigerant causes refrigerant poisoning. Refrigerant contains chemicals known as fluorinated hydrocarbons or Freon. Freon is an odorless and tasteless gas, which when deeply inhaled cuts off oxygen to cells and lungs.
Regularly inhaling high concentrations of Freon can cause breathing problems, organ damage, fluid build-up in the lungs or sudden death. However, limited exposure to Freon is not as dangerous. That means if refrigerant spills on your skin or you breathe near an open container, then the symptoms are only mildly harmful.
On the other hand, the rule of thumb is to avoid any exposure at all.
Q: Can You Use Recovered Refrigerant?
Yes, but under certain conditions. First, it is important to remember the law. EPA demands that contractors, technicians, or DIY enthusiasts recover all refrigerant and dispose of it properly. Proper disposal usually involves taking the refrigerant to an approved company for incineration.
It is a violation to release the refrigerant into the atmosphere, and it is also a violation to reuse recovered refrigerant in a different system/equipment. That said, the EPA still allows reuse but only under these three circumstances:
- reusing the refrigerant in the same equipment once maintenance or repair is complete
- reusing in a system owned by the same person or business and at the same address
- after taking the refrigerant to an approved reclamation company for reclamation
Q: What Does Refrigerant Reclamation Mean?
According to the EPA, it is the processing of previously used refrigerant gas in a refrigerant loop until the specifications for new refrigerant gas are met.
Reclamation is never done by an individual but rather an EPA-certified reclaimer. The reclaimer must adhere to the rules and regulations set by EPA regarding recovered refrigerant according to the Clean Air Act of 1990.
Q: What Is Recycled Refrigerant?
Refrigerant recycling is the process under which the contaminants contained in the refrigerant are reduced to facilitate reuse in the same equipment or other equipment owned by the same person.
It is different from refrigerant reclamation because the purity achieved after recycling does not meet the set EPA standards. Oil separation and filtration processes are used for recycling.
The most significant benefit of recycling is cost saving. That is because the R-22 supply is continuously diminishing and yet the demand remains. As a result, the price rises.
Q: How Does One Facilitate Safety During Refrigerant Recovery?
First, you need a pair of goggles and a set of gloves to prevent frostbite.
Second, you must have charging hoses complete with the ball valve ends. The shorter the hoses, the better. Short hoses reduce the impact on the environment and facilitate efficiency.
Third, ensure you have a quality recovery unit or machine. It must have a CPR (Compression Protection Regulator) valve, a large condenser, and a high-pressure cutout rated for at least 510 PSI.
Ready To Buy The Best Refrigerant Recovery Machine?
The best refrigerant recovery pumps should be compact for easy mobility. It should also be highly advanced to handle both light and heavy workloads. Moreover, such a machine must be able to handle more than one refrigerant whether in the liquid or gaseous state.
