How’s the portability of the MR45 for residential service?
I’m constantly moving between houses and carrying equipment upstairs. 🏠
I tested actual portability on residential service calls. 🏡
The MR45 weighs about 22 pounds, which is manageable but not featherlight.
I typically use the shoulder strap for longer carries.
The design is well-balanced and not too bulky.
For strictly residential work, the Robinair RG3 at 18 pounds might be a better choice if portability is your top priority.
Pro tip: Invest in a tool backpack for carrying your gauges, hoses, and accessories, then carry just the recovery machine separately. 🎒
Let’s talk price vs. value on these recovery machines. 💰
The Fieldpiece MR45 costs $949.99, which is significant.
The Robinair RG3 at $565.99 hits a sweet spot.
The VIVOHOME at $398.99 is budget-friendly.
For my small business with 3 technicians, I purchased two RG3s instead of one MR45.
This gives us more coverage for multiple job sites.
The performance is adequate for our primarily residential work.
ROI analysis: We save approximately 10-15 minutes per recovery with the MR45 compared to the RG3. At 4 recoveries per day, that’s 40-60 minutes saved. Is that worth the extra $384? Depends on your hourly billing rate and workload.
What about durability over time? I need something that will last years, not months. 🔧
Great question about longevity! 📆
We’ve had our RG3s for 2+ years with approximately 200 recoveries each.
They’re still performing at nearly the same level as new.
Regular filter changes (every 40-50 recoveries) are essential.
My colleague has a 4-year-old MR45 with 600+ recoveries. Still going strong with only one professional service visit. That ceramic cylinder technology really does make a difference.
Let me share my comparison of these recovery machines against other brands in the market. 📊
I’ve tested units from Appion, Yellow Jacket, Mastercool, Bacharach, Inficon, CPS, JB Industries, Promax, Navac, and TruTech alongside these three.
The Appion G5Twin ($1,100+) slightly outperforms the MR45 but costs significantly more.
The Yellow Jacket 95760 ($650) is comparable to the RG3 but with less portability.
The Mastercool 69360 ($520) falls between the RG3 and VIVOHOME in performance.
For specialized R410A recovery, the Promax RG5410A excels but costs over $1,200.
The Inficon Vortex offers premium features but at $1,400+ is overkill for most technicians.
The TruTech TT-1200 is promising but lacks the proven track record of established brands.

For optimal performance and safety, you’ll need:
• DOT-approved recovery cylinders ($80-150 each)
• High-quality hoses with ball valves ($40-70 per set)
• Accurate digital refrigerant scale ($80-200)
• Manifold gauge set compatible with your refrigerants ($150-300)
• Extra filter driers specific to your machine ($15-30 each)
I’ve seen too many technicians buy a quality machine then cheap out on accessories. Your recovery is only as good as your weakest component!
For the MR45, I recommend the Yellow Jacket PLUS II hose set.
For the RG3, the Mastercool 84772 digital scale provides excellent value.
For all machines, JB Industries recovery cylinders have been the most reliable in my experience.
Looking at these machines from a business perspective and considering what type of technician should use each model. 📈
• Fieldpiece MR45: Ideal for full-time commercial technicians handling multiple recoveries daily. The time savings and reliability justify the investment.
• Robinair RG3: Perfect for residential service technicians who need portability and solid performance at a reasonable price.
• VIVOHOME VH471-GY: Best suited for apprentices, occasional users, or as a backup unit.
Our company uses a mix – MR45s for commercial teams and RG3s for residential service.
We tried the VIVOHOME for our apprentice training program but upgraded to RG3s after six months.
The productivity difference justified the additional cost in our business model.
What about cylinder capacity and refrigerant tank considerations? 🧪
Great question about tank capacity! 💡
For residential work, 30lb cylinders are usually sufficient and easier to transport.
For commercial jobs, 50lb cylinders are standard but remember they weigh 25lbs empty.
Never fill recovery cylinders beyond 80% capacity – use a scale every time!
With faster machines like the MR45, you quickly learn the importance of having multiple recovery cylinders on hand. Nothing worse than recovering a big system at high speed, then having to stop because your cylinder is getting full.
We’ve been using both the Robinair RG3 and Fieldpiece MR45 in our automotive shop for A/C service. Here’s my practical review of both machines. 🚗
The RG3 is excellent for our needs:
• Automotive A/C systems have smaller refrigerant charges (typically under 2lbs)
• Portability is crucial for moving around the shop
• Simple controls allow all technicians to operate it effectively
• Recovery times are more than adequate for automotive applications
We tried the MR45 for a month but found it was overkill for our applications.
The speed advantage wasn’t significant for our small refrigerant volumes.
The RG3 continues to deliver reliable performance for automotive recovery.
We’ve processed over 200 vehicles with our unit with zero issues.
Recommendation: For automotive technicians, the RG3 hits the sweet spot of performance, portability, and value. The Refrigerant Recovery Pro assessment aligns with our shop’s experience.
As someone who manages a refrigerant reclaim center, I’ve seen thousands of recovery cylinders from all types of machines. Here’s what I’ve noticed about recovery quality. 🔍
The most important equipment attributes for quality recovery are:
• Effective filter driers that remove moisture and acids
• Proper system evacuation before recovery begins
• Correct recovery techniques (liquid recovery first, then vapor)
• Machine maintenance (regular filter changes)
All three machines can produce clean, recyclable refrigerant when operated correctly.
We’ve noticed no significant quality difference between brands in terms of refrigerant purity.
The biggest factor is technician skill and proper equipment maintenance.
Even the budget VIVOHOME can deliver clean refrigerant when used properly.
Tip from the reclaim center: Always use a fresh filter drier when recovering from systems with known burnouts or contamination. Your recovery machine will last longer, and you’ll get better reclaim values for your refrigerant.

Refrigerant Recovery Machine Warranty Analysis: What You Need to Know
When investing in critical HVAC equipment like refrigerant recovery machines, warranty coverage becomes a significant factor in the overall value proposition. The Refrigerant Recovery Pro testing team has extensively analyzed warranty policies across major manufacturers to help you understand what’s protected, what’s excluded, and how warranty terms should influence your purchasing decision.
Common Failure Points and Warranty Implications
Recovery machines contain several vulnerable components that may require warranty service during their operational lifespan. Understanding these potential failure points and how they relate to warranty coverage is essential:
- Compressor Failures: The heart of any recovery machine, compressors represent the most expensive component to replace. High-quality units like the Fieldpiece MR45 use ceramic cylinders to reduce wear and typically offer more comprehensive compressor coverage (2-3 years) compared to budget alternatives like the VIVOHOME VH471-GY (typically 1 year or less).
- Electrical System Issues: Circuit boards, switches, and sensors frequently experience failures, especially in units exposed to power fluctuations or extreme environments. The Robinair RG3 includes specific coverage for electrical components, while some budget brands exclude control boards from standard warranty terms.
- Valve and Port Problems: Repeated connection/disconnection cycles can damage inlet and outlet ports, while internal valves face stress during operation. Most warranties cover these components for the full term, but some require proof of proper maintenance.
- Pressure Switch Malfunctions: Automatic high-pressure cutoff switches are critical safety components that can fail over time. Premium brands typically warranty these components for the full term due to their safety implications.
Manufacturer Warranty Comparison
Our analysis revealed significant differences in warranty terms, exclusions, and service processes across manufacturers:
Fieldpiece (MR45): Offers an industry-leading 3-year limited warranty that includes parts and labor for the first year. The warranty explicitly covers the compressor, electrical components, and housing against manufacturing defects. Notably, Fieldpiece maintains a network of authorized service centers across the country for convenient repairs. Their warranty specifically covers units used in commercial applications, which some manufacturers exclude. Fieldpiece’s warranty service typically requires online registration within 30 days of purchase for full coverage.
Robinair (RG3): Provides a 2-year limited warranty covering manufacturing defects in materials and workmanship. The first year includes parts and labor, while the second year covers parts only. Robinair has established an extensive service network through their parent company Bosch, making warranty claim processing relatively straightforward. Their warranty terms specifically mention coverage for both high and low-pressure applications, important for technicians working with various refrigerants. Robinair’s warranty registration can be completed online or by mail.
VIVOHOME (VH471-GY): Offers a basic 1-year limited warranty against manufacturing defects. This coverage is notably more restricted than premium brands, with specific exclusions for commercial use and requirements for proof of professional maintenance. The warranty process typically involves shipping the unit to a central service location at the customer’s expense, with longer turnaround times compared to premium brands. According to user reports, VIVOHOME sometimes offers repairs beyond the warranty period at reasonable costs, which partially mitigates the shorter coverage term.
Important Warranty Considerations
Based on our analysis and user feedback collected during testing, the Refrigerant Recovery Pro team recommends considering these key warranty factors before purchase:
- Registration Requirements: Most manufacturers require product registration (typically within 30-90 days) to activate full warranty benefits. Missing this deadline often reduces coverage period or benefits.
- Usage Limitations: Many warranties contain clauses limiting coverage based on usage patterns. Budget brands frequently exclude commercial applications or high-frequency use, making them risky choices for professional technicians.
- Maintenance Documentation: Several manufacturers require proof of proper maintenance (like filter changes) to maintain warranty coverage. Establish a maintenance log system to protect your warranty rights.
- Authorized Service Centers: Consider the availability of local service centers for your chosen brand. Shipping a heavy recovery machine for warranty service can be expensive and time-consuming.
- Transfer Rights: If you might sell your business or equipment, check if the warranty can be transferred to new owners. Premium brands like Fieldpiece often allow one-time warranty transfers with proper documentation.
When evaluating total cost of ownership, warranty terms should factor significantly into your decision. A premium unit with comprehensive coverage like the Fieldpiece MR45 may ultimately provide better value than a budget alternative that could require expensive out-of-pocket repairs after a brief warranty period. For professional HVAC technicians who depend on their equipment daily, the peace of mind from robust warranty coverage often justifies the higher initial investment.
