Best refrigerant recovery machine for residential HVAC and mini-split work

The old condenser is coming out. The refrigerant needs a cylinder, and your crew needs to get on with the replacement. Buy a recovery machine that’s easy to carry, easy to read and matched to the refrigerants on your calls.

Start with the Fieldpiece MR45 for everyday residential and mini-split service. Its 22 lb weight, backlit pressure display and selectable auto-stop levels make a useful van setup. Choose NAVAC’s NRDD for configurable restart controls, or CPS’s TRS600 if you prefer analog gauges and already carry the larger cylinder its instructions specify.

Quick picks: which machine fits your van?

Your workday	Our pick	Why you’ll like it
Residential replacements and mini-split service	Fieldpiece MR45	22 lb, digital pressures, self-purge and three auto-stop levels
You want to choose how recovery restarts	NAVAC NRDD	Manual restart, automatic restart and continuous-run low-pressure modes
You prefer gauges and quarter-turn valves	CPS TRS600	Analog controls and a cleanable inlet filter; plan around its specified cylinder kit

Compare A2L compatibility, power and carrying weight

Machine	A2L status	US power	Maker-listed weight	Main controls
Fieldpiece MR45	Compatible, including R-32 and R-454B	95–130V AC, 60Hz; 12A maximum	22 lb	Dual pressure display, one routing dial, three auto-stop levels
NAVAC NRDD	Compatible; covered by NAVAC’s A2L service notice	115V/60Hz; 12A maximum	25.4 lb	Backlit display, low-pressure modes and purge function
CPS TRS600	Compatible, including R-32 and R-454B; ignition-proof design	115V/60Hz; 1,000W	28 lb	Suction/discharge gauges and quarter-turn valves

The NRDD weight is from NAVAC’s current product page. Buy the 115V TRS600 for the US setup here; TRS600E is a different-voltage model.

Recovery rates: liquid, vapor and push-pull

The table uses R-410A test rates in kg/min, quoted in each maker’s published data. Read across all three modes: the big liquid number and the much smaller vapor number describe different parts of recovery.

Machine	Direct liquid	Direct vapor	Push-pull liquid
Fieldpiece MR45	5.6	0.33	Rate not published in current manual
NAVAC NRDD	6.55	0.34	8.35
CPS TRS600	5.41	0.32	14.3

MR45 supports push-pull; Fieldpiece’s manual reserves that method for larger systems with at least 30 lb of liquid refrigerant. For a residential service kit, put direct recovery, hose layout and easy cylinder weighing ahead of the biggest push-pull figure.

Fieldpiece MR45: the everyday residential pick

Why you’ll like it: The MR45 puts both pressures on a large backlit display and routes recovery through one rubberized dial. Its variable-speed DC motor speeds up during vapor recovery, and the self-purge function moves refrigerant remaining in the machine into the recovery cylinder.

The 22 lb machine is the lightest of these three. Its operating range extends down to 95V AC, a useful specification to compare when you’re choosing the power setup for the call. Auto-stop choices are 0 psig by default, −10 inHg and −20 inHg.

Bring with it: A compatible recovery cylinder, scale, short recovery hoses and an inlet filter drier. Fieldpiece recommends changing the drier often to protect the machine from contamination.

NAVAC NRDD: choose how the machine restarts

Why you’ll like it: The NRDD combines a brushless DC motor, twin-cylinder compressor and backlit digital display with three low-pressure modes. LP1 stops with manual restart; LP2 allows automatic restart; LP3 runs continuously. That puts the restart choice in the technician’s hands.

It also has a purge function and an oversized two-row condenser. Choose it if those controls fit your shop’s recovery routine; use the refrigerant-specific operating instructions when selecting the mode.

Bring with it: A digital scale and an authorized refillable recovery tank. NAVAC calls for a filter drier, with a separate filter for each refrigerant type.

Sources: NRDD design and specifications and controls, cylinder and filter instructions.

CPS TRS600: analog controls, larger cylinder kit

Why you’ll like it: Two gauges and quarter-turn valves keep the pressures and controls in view. The 2/3 HP, two-cylinder machine has an ignition-proof switch, sealed start relay and a cleanable 100-mesh inlet filter. The US model runs on 115V/60Hz and weighs 28 lb.

Bring with it: The direct-recovery instructions specify an evacuated 90 lb-or-larger DOT tank rated for 550 psi/38 bar. That’s a substantial cylinder requirement for a residential van; choose this setup when that kit fits your work.

CPS specifies a short ¼-inch inside-diameter suction hose for direct recovery and ⅜-inch hoses in its push-pull setup. Keep the complete hose/cylinder kit together so the machine arrives ready for the job.

Sources: CPS TRS600 features and A2L compatibility and US specifications, hose and cylinder instructions.

Build the recovery kit around the cylinder and hoses

The machine is one part of the kit. Put these on the van checklist:

• Recovery cylinder: An evacuated, refillable recovery cylinder suitable for the refrigerant, with the pressure/capacity specified for your machine and method.
• Refrigerant scale: Weigh the cylinder throughout recovery. Fieldpiece and NAVAC specify a maximum 80% fill; leave expansion space in the cylinder.
• Hoses and fittings: Fieldpiece recommends short ⅜-inch hoses with ¼-inch fittings. CPS’s direct and push-pull hose instructions differ, as listed above.
• Filters: Keep the machine’s inlet screen clean and carry the filter drier specified by its maker.
• Refrigerant identity: Match the cylinder to the refrigerant and keep different refrigerants separate.

Recovery first, evacuation after the repair

A recovery machine moves refrigerant out of the system and into a cylinder. After the repair, use the vacuum pump for the deep evacuation. Fieldpiece explicitly separates those jobs in its MR45 manual.

Our HVAC vacuum-pump guide covers the pump and system-side micron gauge; the digital manifold guide sorts pressure/temperature probes from evacuation gear.

US technicians servicing equipment that could release refrigerant need the appropriate EPA Section 608 certification.

Put the recovered refrigerant on the job record

Finish with a record the office and next tech can use. Save the equipment, refrigerant type, cylinder ID, start/end weights, net amount recovered, date and technician. Add a scale photo and a legible cylinder-label photo, then record where the recovered refrigerant went.

Copy this into a job note:

• Equipment / refrigerant: [model, serial, refrigerant]
• Recovery cylinder: [ID and refrigerant]
• Weight: [start, finish, net recovered; units]
• Technician / date: [name and date]
• Next destination: [reuse, reclamation or other recorded disposition]
• Photos: [scale reading and cylinder label]

Make Jobber the office handoff: keep the recovered amount, refrigerant and supporting photos with the job that gets closed out.

In Jobber, add the note and attachments to the job; notes are internal by default, and you can select attachments when emailing the client. HCP alternative: keep the technical handoff in private job/estimate notes and attach the chosen photos or documents to the customer’s estimate or invoice. A clear recovery entry turns “we took it out” into a usable service history.

Sources: Jobber notes and attachments, HCP private notes and HCP customer attachments.

For most residential vans, start with MR45, a well-matched cylinder and tidy hoses. Choose NRDD for its restart controls or TRS600 for an analog setup with the specified larger tank. Keep the recovered weight with the job, and the whole crew gets a cleaner handoff.

For a reusable recovered-weight record, use the HVAC template in Jobber vs HCP job forms, with technician completion and a customer-facing PDF handoff.

Pair the kit with a refrigerant charging scale to weigh the cylinder and save the measured amount with the job.
