Replacement refrigeration compressor is always a joyful moment, marking the end of painful repairs or the purchase of new equipment. However, after the successful installation of a new unit, the owner is faced with a completely logical and practical question: what to do with the heavy, bulky and technically complex “old man” that was left as an inheritance? You cannot simply throw it into the nearest household waste container, since this equipment contains technical oil and refrigerant residues, which makes it hazardous to the environment.
In addition, the old motor is a valuable source non-ferrous metals, the cost of which can pleasantly offset part of the repair costs. In this article, we will analyze in detail all possible options for legal and profitable disposal, explain how to properly prepare a device for delivery and where people are willing to pay real money for it. You will learn how conditions differ at different collection points and why motor-compressor is valued higher than ordinary ferrous scrap.
⚠️ Attention: It is strictly forbidden to open the compressor housing yourself at home in order to extract copper. There may be compressed gas under pressure inside, and freon vapors upon contact with an open flame (for example, when cutting with a grinder) form toxic phosgene.Why you can’t just throw the compressor in the trash
Many people mistakenly believe that the old unit is just a piece of iron, and its place is on a regular landfill However, the design of a hermetic compressor is more complex than it seems at first glance. Inside the steel casing there is not only the motor winding, but also a special one, which provides lubrication of the rubbing parts. When the housing is destroyed at a solid waste landfill, this oil inevitably gets into the soil and groundwater, causing irreparable environmental damage. compressor oil, which provides lubrication of rubbing parts. When the housing is destroyed at a solid waste landfill, this oil inevitably gets into the soil and groundwater, causing irreparable environmental damage.
The second important aspect is the refrigerant residues. Even if the refrigerator stopped cooling years ago, a certain amount of freon may remain in the circulation system and in the compressor itself. Different types refrigerantssuch as R134a or isobutane have different effects on the atmosphere, but their direct release is strictly regulated by international environmental protocols. Recycling must be carried out by specialized enterprises licensed to work with hazardous waste.
The third argument in favor of proper disposal is economic. When you throw away your compressor, you're losing potential revenue. This assembly contains a significant amount of copper in the stator windings, as well as brass and aluminum in the piping. By handing over the device to a specialized point, you not only help nature, but also receive a monetary reward, the size of which depends on the current rate non-ferrous scrap.
📊 What do you plan to do with the old compressor?I will throw it in a container::I will sell it for scrap metal::I will give it to the craftsmen for spare parts::I will leave it lie in the garageDeposit options: where they accept compressors
Finding a place for disposal depends on whether you are willing to spend time on delivery or prefer to call a specialist. There are several main channels through which an old unit can be transferred for recycling. The most common option is collection points scrap metal. They are found in almost every major city and often accept equipment “as is,” that is, together with the casing and tubes.
The second option is specialized companies for recycling of household appliances. Such organizations often cooperate with manufacturers of new refrigerators or electronics stores, organizing “Trade-in” programs or simply free removal of old equipment when purchasing new ones. If you changed the entire refrigerator, the store is obliged to accept the old device for recycling, although they may not take on a separate compressor.
The third way is private craftsmen and service centers for the repair of refrigeration equipment. They often require used compressors of certain models (Danfoss, LG, Atlant) for use as spare parts donors or for refurbishment. If your unit is relatively modern and does not have mechanical damage to the body, it can be bought even more expensive than scrap.
- 🏭 Scrap metal collection points: they accept any volume, pay by weight, often require a passport.
- 🚚 Equipment removal services: they take large items, but they can charge money for the service if scrap illiquid.
- 🔧 Service centers: are interested in serviceable or partially working units for spare parts.
⚠️ Attention: Tariffs for scrap acceptance and operating rules for points may vary depending on the region and the current economic situation. Before your trip, be sure to check by phone whether they accept sealed units and whether you need a passport for this.Preparing the compressor for scrap metal
To get the maximum benefit and avoid problems during acceptance, the device must be properly prepared. Reception points divide compressors into two main categories: “motor” (assembled with casing) and “copper” (disassembled). The price per kilogram of pure copper is always significantly higher, but the cutting process requires special tools and skills.
If you plan to hand over the entire unit, your task is to ensure its safety during transportation. Be sure to drain any remaining oil through the service openings, if accessible, or notify the receiver about its presence. It is better to plug or clamp the tubes to prevent fluid from leaking out along the way. For transportation, use durable containers or securely fasten the unit in the body of the car, since the weight of the product can reach 10-12 kg.
Some points require demercurization removal of electronic boards if they are attached to the body (for example, a start-up relay). Although modern hermetic compressors have a minimum of electronics, older models could be equipped with external control units. It is better to remove them and hand them over separately as electronic scrap, which also has its own value.
☑️ Checklist for preparation for delivery
Completed: 0 / 1How much does it cost to hand over a compressor: price calculation
The cost of an old compressor consists of several factors: weight of the device, percentage exit non-ferrous metal and current quotes on the stock exchange. A sealed block weighs on average from 8 to 12 kilograms. The copper yield, depending on the model and year of manufacture, ranges from 1 to 2.5 kg. The rest of the mass is occupied by body steel and cast iron.
Receivers often use a simplified calculation system. They can offer a fixed price per “piece” or estimate the weight of the entire product under the “electric motors” or “mix” category. If you decide to cut the unit yourself by opening the casing and removing the windings, you will receive the price of the “copper” category, but will lose weight, since steel and cast iron will not be accepted from you or will be accepted cheaply.
Below is a comparative table showing the approximate difference in cost for different delivery methods. The numbers are averaged and may vary depending on the region and the specific collection point.

The price depends on the thickness of the winding wire and the purity of the alloy. Old Soviet models used thicker copper, while modern ones often use aluminum or its alloys, which are valued much lower.
Alternative ways to use an old unit
Before throwing the compressor into the scrapyard, think: perhaps it will find a worthy use on the farm. Motor-compressor from a refrigerator is, in fact, a ready-made vacuum pump or compressor for airbrushing, inflating tires or pneumatic tools. Craftsmen often remake them, creating functional devices for a garage or workshop.
To create a compressor you will need a receiver (an old fire extinguisher or gas cylinder will do), a gearbox, a pressure gauge and hoses. Such a homemade device is capable of producing pressure up to 6-8 atmospheres, which is quite enough for most household tasks. This is a great way to extend the life of your equipment and save your budget.
The compressor can also be used to create fountains in decorative ponds or as an aeration system for large-volume aquariums. In skillful hands, even a seemingly faulty unit can find a second life. However, remember that such experiments require compliance with safety precautions.
Safety rules for dismantling and transportation
Removing the compressor from the refrigerator is a process that requires caution. The unit is attached to the refrigerator frame using four shock-absorbing bushings and welded studs. When unscrewing the nuts, it is important not to damage the copper tubes if you plan to sell the copper separately. Use open-end wrenches of the appropriate size to avoid stripping the threads.
Transportation should be carried out in an upright position or with a minimum tilt so that residual oil does not leak into the vehicle interior. If you are transporting multiple compressors, secure them securely to prevent them from rolling around in the truck. A heavy metal body during sudden braking can cause serious injuries or damage the interior.
When working with tools (grinder, hacksaw) for cutting, use safety glasses and gloves. Steel shavings and dust from winding insulation may enter the eyes or respiratory tract. Work in a well-ventilated area or outdoors.
⚠️ Attention: Never attempt to cut the sealed compressor casing if pressurized freon remains inside. This may cause an explosion. Make sure that the system is completely depressurized and the pressure is released through the puncture of the tubes before starting any work on the housing.Frequently asked questions (FAQ)
Will they accept a compressor without a passport?
In most large network scrap metal collection points, a passport is mandatory for individuals, as they keep strict records of incoming scrap to prevent theft. However, in small private centers or from “assemblers” they can accept without documents, but the price will be lower, and the guarantee of environmental safety is in question.
How much copper is in one compressor from a refrigerator?
On average, a standard household compressor contains from 0.8 to 1.5 kg of copper. The exact amount depends on engine power, year of manufacture and manufacturer. In older models, the yield of non-ferrous metal was higher; in modern ones, aluminum or its alloys are often used, which reduces the value of scrap.
Is it possible to return a compressor for free?
Yes, many companies involved in the removal of bulky waste can pick up an old refrigerator or compressor for free, especially if you order the removal of other equipment. There are also eco-boxes or recycling promotions held by electronics stores.
Is it dangerous to store an old compressor at home?
If the compressor is intact, sealed and the oil has been drained, it does not pose a direct danger when stored in a dry room (garage, pantry). Danger arises only if it is damaged, heated, or you try to disassemble it yourself without the appropriate knowledge and tools.
What to do if the compressor leaks oil?
Collect the oil in a sealed container (plastic bottle) and take it to waste oil collection points. Pouring industrial oil down the drain or onto the ground is strictly prohibited by environmental legislation.
