Best AC Recovery Machine for Workshop in 2026
Why is an AC refrigerant recovery and recharge machine so important for a workshop? According to federal law, releasing refrigerant into the atmosphere is illegal. Technicians must use a refrigerant recovery machine to remove refrigerant from damaged or scrapped AC systems. This helps protect the environment and avoids unnecessary legal risks.
Usually, there are two ways to recover refrigerant from an AC system:
- Use the vehicle’s AC system pump to move the available liquid refrigerant into a certified recovery cylinder.
- Use a dedicated refrigerant recovery machine. This method is more efficient and offers better control and accuracy, which makes it ideal for workshops with frequent AC service.
This article focuses on the second method. We will also introduce a reliable AC refrigerant recovery and recharge machine — AUTOOL LM708 — to help improve your workshop efficiency and keep your work compliant with environmental regulations.
What is the AUTOOL LM708 Refrigerant Recovery and Recharge Machine?
The AUTOOL LM708 automotive refrigerant recovery system features an independent dual system and a built-in vehicle database. It supports two types of refrigerants: R-134a and HFO-1234yf, each with a capacity of 10 kg.
The system can automatically recover refrigerant, perform vacuuming, and recharge refrigerant for vehicles that use R-134a or HFO-1234yf. It greatly improves efficiency in automotive AC service. The operation is simple, and the process is accurate and efficient.
