#1 · Best Overall

1. Airtek AC-Dual

• Weight: 275 lb

Best for: Dual-Refrigerant Shop Service.

Why it ranks #1: Supports R134a and HFO1234yf, includes two empty tanks, and switches gases in about 10 minutes without component changes.

Two attached, empty refrigerant tanks let the Airtek AC-Dual handle R134a and HFO1234yf without changing components between gases. Its fully automatic recovery, vacuum, and recharge workflow is intended for technicians who want to select the vehicle refrigerant and let the machine prepare and run the service cycle.

Airtek specifies a 10-minute switch between R134a and HFO1234yf systems, and says no component changes are needed; that makes alternating between supported refrigerants more straightforward. The machine serves domestic and foreign vehicles, including electric and hybrid models, while software control prevents wrong-oil injection. Oil injection is specified for non-EV and hybrid vehicles. At 275 pounds and 110 volts, it is a substantial shop machine rather than a lightweight portable unit.

Skip it if you service only R134a vehicles; the Robinair 34288NI is specified for that refrigerant alone.

Choose the Airtek AC-Dual for a shop servicing both R134a and HFO1234yf vehicles, including electric and hybrid models. Its automatic workflow and oil safeguards suit varied service work, but its 275-pound weight calls for a suitable stationary workspace.

#4

4. AUTOKATO AC2100

• Weight: 254 lb

Best for: Single-Gas Shop Selection.

Why it ranks #4: Offers an R134a or R1234yf configuration and quick couplers for both, but the selected refrigerant cannot be changed after initial use.

The AUTOKATO AC2100 lets buyers choose an R134a or R1234yf configuration, with quick couplers for both refrigerant types supplied. That choice is also its key operating boundary: each machine is optimized for one selected refrigerant, and the listing says it cannot be switched after the equipment has used refrigerant.

AUTOKATO specifies automatic recovery, evacuation, and recharge, bringing those tasks into one service workflow. Quick couplers for both refrigerant types are included, but the machine is configured for the selected refrigerant; the default installed coupler is for R1234yf. The listing says switching to R134a requires replacing the coupler, and that a machine already used with 1234yf cannot be switched. This makes the initial refrigerant choice central to shop planning.

Skip it if you need one machine to alternate gases after use; the Airtek AC-Dual switches between R134a and HFO1234yf.

The AC2100 suits a shop that can select one refrigerant configuration and keep it dedicated to that service. Automatic recovery, evacuation, and recharge simplify the workflow, but the stated no-switch-after-use rule makes mixed-gas flexibility a poor fit.
