Fieldpiece products are tough, versatile, innovative and can handle the demands of working in HVACR. That’s because they were designed with the idea that every HVACR professional in the field deserves the best tools possible. Here are just a few highlights of some innovative features and technologies we developed to make your jobs easier, faster and better!

 

Stop Recovery on a Dime with Zero-Stop™

When recovering refrigerant, the Fieldpiece MR45 Refrigerant Recovery Machine has the ability to automatically stop the recovery at 0 psig, with additional auto stop levels of -10 inHg and -20 inHg. Stopping the recovery at 0 psig is an industry standard when recovering A2L refrigerants to prevent air from contaminating the refrigerant in the recovery cylinder.

Change Vacuum Pump Oil on the Fly with RunQuick® Oil Change

Regularly changing the oil in a vacuum pump is crucial for maintaining optimal performance and  longevity. The oil in a vacuum pump reduces friction and wear between moving parts, and over time, the oil can become contaminated with debris, moisture, and by-products of the pumping process, making clean oil an essential part to maintaining peak pump performance. To make these oil changes as quick and easy as possible, Fieldpiece vacuum pumps utilize the RunQuick Oil Change system, which allows technicians to change their oil while the pump is running. In as little as 30 seconds technicians can swap out their old oil without losing vacuum, saving time on the jobsite and increasing the life of the pump.

 

Eliminate the Water Trap and Extend Sensor Life with HydroCycle™ Pump and SensorVault™ Technology

The Fieldpiece CAT85 and CAT45 Combustion Analyzers feature cutting edge improvements like no other combustion analyzer. The CAT85 showcases the HydroCycle Pump, which condenses and returns water to the flu. This eliminates the need for a water trap, as well as the need to buy water trap filters, lowering the cost of ownership for technicians.

The Fieldpiece CAT85 and CAT45 Combustion Analyzers also feature SensorVault technology that help sensors last longer. SensorVault  automatically seals the sensors when the unit is powered off – isolating them from ambient oxygen, thus reducing sensor degradation when they’re in storage. If the sensor needs to be changed, they’re field-replaceable and come with a four-year warranty. This means maximum uptime on the job site, and lower cost of ownership for techs.

Measure System Temps in a Flash with Rapid Rail™ Sensor Technology

The JL3PC Job Link® System Pipe Clamp Probe, allows techs to get accurate temperature readings in seconds. By incorporating Fieldpiece’s patented Rapid Rail Sensor Technology, these clamps utilize the pipe itself as part of the sensor to immediately react to changes in system temperature. They provide accurate readings on wet or damp pipes and are not affected by wind, ambient temperature, or any other outside influence. Instant readings make it easier for a tech to get a superheat and/or subcooling measurement.

These technologies are just the tip of the innovation iceberg that Fieldpiece brings to tools and test instruments.  Fieldpiece doesn’t just introduce products, we introduce solutions designed for HVACR techs, like integrating a dual port manometer into our combustion analyzer to save space in your tool bag and color tags for hoses so you can easily swap for a spare rather than purchase a whole set.  We’re on the job with you, discovering your pain points and finding solutions.

For an HVACR professional, working on heating systems during winter demands precision. You bring your expertise, but without the right HVAC tools, you are missing the backbone of your work. 

From diagnostics to safety, it is the tools in your truck that help you get the job done right. If you do not have these crucial HVAC tools for the heating season, now is the time to get them. 

Explore these essentials tools that help you keep customers warm and comfortable, even on the coldest days. 

 

Combustion Analyzers: Essential for Efficiency and Safety 

A combustion analyzer is a critical tool for HVACR professionals during the winter. This tool measures the performance of combustion-based heating systems such as furnaces. When you need data on oxygen levels, carbon monoxide emissions, carbon dioxide, draft pressure, and flue gas temperature, this is the HVAC tool to have in your took kit.  

 

Efficiency Optimization 

Combustion analyzers provide precise data that allows HVACR technicians to adjust heating systems for maximum efficiency. Adjusting for the correct fuel-to-air ratio helps minimize energy consumption. It also reduces heating costs and lowers the system’s environmental footprint. 

 

Safety 

A combustion analyzer, an HVAC tool all technicians need, helps identify problems like incomplete combustion or inefficient venting. Both can lead to the release of carbon monoxide. By detecting problems early, technicians can prevent dangerous situations.  

The ability to fine-tune heating systems and detect potential hazards makes the combustion analyzer a cornerstone of winter HVAC work. 

 

Carbon Monoxide Detectors Serve as Air Quality Guardians 

In the winter, heating systems run at full steam, making it a prime time for carbon monoxide leaks. Carbon monoxide (CO) detectors play a critical role for keeping you and your customers safe. 

As a HVACR professional you will want a CO detector that has a fast reaction time and measures CO in parts per million (ppm). The best CO detectors have an electrochemical sensor that is fast enough for walk-around tests (responds to changes in CO levels in real time). 

Whether inspecting furnaces, water heaters, or other heating equipment, having the right CO detector that promptly alert technicians to the presence of CO is a must. 

 

Clamp Meter: Electrical Insights for Troubleshooting  

Another indispensable HVAC tool for HVACR professionals in winter is the clamp meter.  In the winter months, the electrical components of heating systems work relentlessly. The clamp meter empowers technicians to diagnose electrical issues, such as problems with heating elements or motors. 

A clamp meter features a clamp jaw that securely wraps around a wire allowing for quick and easy measurement of the amperage and frequency without the technician needing to touch the circuit directly. 

Using a clamp meter helps technicians identify electrical issues before they lead to system breakdowns during routine HVAC maintenance. This proactive approach improves the reliability and longevity of heating systems. 

 

Dual Port Manometers Balance Pressure for Efficiency 

Think of the dual port manometer as the pressure specialist for HVAC work. The right pressure balance in HVAC systems ensures warm air flows evenly throughout a building. This HVAC tool helps find and fix any pressure issues. 

The manometer helps HVACR techs see if the air moves correctly in a heating system. If not, it shows where to make adjustments. 

The best feature? It measures pressure on the supply and return sides of the system. Measuring pressure on both sides is beneficial for several reasons: 

• Balances the system
• Optimizes efficiency
• Prevents over or underheating

As a diagnostic tool, a dual port manometer provides valuable insight into issues like clogged ducts, air leaks, or problems with valves and dampers. Technicians can use this information to identify and correct problems quickly. 

  

Psychrometer: Master of Temperature and Humidity  

HVACR technicians rely on a psychrometer because it provides critical information they cannot do without. 

 

System Performance 

To assess the performance of heating systems effectively, HVACR technicians need to know the air’s temperature and humidity. A psychrometer provides this data, enabling techs to fine-tune heating systems for optimal performance, energy efficiency, and comfort. 

  

Preventive Maintenance 

Regular use of a psychrometer during winter enables HVACR technicians to identify and address problems before they escalate. This proactive approach enhances the reliability of heating systems, ensuring they perform at their best when needed most. 

A psychrometer is a vital HVAC tool for HVACR technicians during the winter. It helps maintain indoor comfort and optimization of system performance. Without it, HVACR professionals would be working blind when it comes to assessing and managing critical temperature and humidity levels in heating systems. 

 

Don’t Wait to Upgrade Your HVAC Tools for the Heating Season 

All HVACR techs should have these tools ready for winter service calls. Without the right HVAC tools, you risk errors in identifying HVAC issues and completing repairs.

As HVACR professionals, we all play a role in combating climate change. One important way is to safely recover, recycle and reclaim all refrigerant from systems. How much of an impact will we have by doing this? One pound of leaked HFC has the same impact on the atmosphere as thousands of pounds of carbon dioxide. While it may be heating season now, the proliferation of heat pump installations to both heat and cool interiors highlights the critical importance of the “three R’s” year-round. 

 

What the A1 Phaseout and A2L Adoption Means for You 

Because commonly used refrigerants are potent greenhouse gases, the EPA is phasing out refrigerants with a high global warming potential (GWP) in most new equipment starting January 1, 2025. These discontinued A1 refrigerants include R134a, R404A and R410A. Your diligence in recovering, recycling, and reclaiming these refrigerants not only limits their release into the atmosphere but it helps ensure an adequate supply of reclaimed refrigerants to service the installed base of A1 systems. The production phase down of today’s major refrigerants will inevitably increase charging costs, but full participation in recycling and reclaiming will help mitigate the rise in costs – saving your customers money.   

 

The phase down of A1 refrigerants is leading to the adoption of A2L refrigerants, such as R-32 and R454B, which have a low toxicity and low GWP. A2L refrigerants are mildly flammable compared to A1’s, however they are still difficult to ignite with a relatively low energy release and low flame propagation speed. When installing or servicing an A2L system, it is important to ensure that your service tool and test equipment is A2L compatible prior to handling A2L refrigerants. 

 

How to Safely Recover Refrigerant  

Before handling refrigerant, be sure to wear the appropriate PPE, such as gloves, safety glasses, and impermeable clothing. Liquid refrigerants can cause frostbite so it’s paramount to avoid skin contact.  

 

When recovering refrigerant, you will want to identify the refrigerant type on the compressor unit and ideally select your recovery cylinder to match for recycling purposes. Find the cylinder capacity on the tank and calculate the maximum fill weight, which should be 80% of the total capacity for safety. Weigh your initial cylinder weight on a refrigerant scale and determine how much refrigerant can be added to the tank from the system. The Fieldpiece SR47 refrigerant scale allows you to monitor both the total tank weight and the added refrigerant weight during the recovery process.  

 

For the fastest recovery, enlist the best-in-class, A2L compatible, Fieldpiece MR45 recovery machine. The variable DC motor adjusts performance to handle liquid and runs twice as fast on vapor, significantly speeding up the recovery process. Read the MR45: Refrigerant Best Practices blog to learn more tips for a smooth recovery. For recycling and reclaiming purposes, remember to document your final recovered refrigerant weight. 

 

Recycled vs. Reclaimed Refrigerant 

You may use recycled refrigerant, meaning used refrigerant that has undergone a basic, on-site cleaning process with certified equipment, only on the same job site. Note that recycled refrigerant cannot be stored on-site for more than 12 months. There are many regulations that HVAC technicians must follow when recycling refrigerants including Section 608 of the Clean Air Act. Make sure your team stays current on training and certification. Typically, your local HVAC supply house will accept drop offs of recovered refrigerant cylinders and submit them to a certified reclaimer. 

 

Refrigerant reprocessed by a certified reclaimer to the industry standard AHRI 700 is considered reclaimed refrigerant. A reclaimer will clean the refrigerant and remove any moisture or toxic particles. They’ll also separate any oil or additives from the refrigerant and dispose of contaminants. Reprocessed refrigerants meet or exceed purity standards for new refrigerant gases and reprocessing will become increasingly more important as the new production of A1 refrigerants is phased down.  

 

The first step to make sure we’re protecting and preserving our planet lies with you, HVACR pros. Recovering refrigerant lies squarely in your hands and we can work together to ensure the proper equipment is used and processes are followed to ensure a steady supply of recycled and reclaimed refrigerant is readily available for the years to come.  

 

The purpose of combustion analysis is to help HVAC technicians ensure fuel-fired heating appliances are running safely and efficiently. Long gone are the days of checking efficiency by the color and shape of the flame. Combustion analyzers measure and calculate a range of variables such as flue temperature, draft pressure, and the byproducts of combustion like oxygen (O₂), carbon dioxide (CO₂) and carbon monoxide (CO). To tap into the full power of your combustion analyzer, here are a few tips and best practices to keep in mind this heating season.

Location, Location, Location

Combustion analysis is all about location. Key measurements are taken in the flue gas after the heat exchanger and prior to any dilution air entering the flue. Typically, the ideal location to measure combustion byproducts, such as CO, is about a foot above the furnace box and at least a foot away from any elbow. Using an existing combustion test access fitting is preferred over drilling into the flue. If an access location must be drilled, reseal the hole following testing with a silicone plug for example, to ensure exhaust gases are not vented into the surrounding space. Silicone is resistant to heat and moisture in the flue, providing a sure seal. When you insert the probe, use a cone lock to hold the sampling tip in the center of flue, at the hottest point.

Warm-up

The best practice is to warm up and insert the combustion analyzer probe prior to firing up the furnace. All measurements should be monitored at start-up, after a system has stabilized and after light out (unit turned off). The analyzer should be turned on and allowed to warm up in fresh air, in order to zero the ambient CO sensor. Avoid starting the analyzer near the exhaust pipe of a service van, or in the furnace room. After the start-up tests, it’s also important to let the furnace run for a few minutes to stabilize before measuring combustion performance.

Monitoring Carbon Monoxide (CO)

During the installation or service of a heating appliance, the fuel and airflow are adjusted to maximize combustion efficiency and safety.  If the adjustments allow too much fuel or too much oxygen into the reaction, the imbalance will lead to incomplete combustion. When this happens, it can create a dangerous amount of CO. While you should always defer to the furnace manufacturer’s recommendations and local regulations, what follows are a few key tips when monitoring CO levels.

After the burners light, the CO should rise and fall and the O2 should slowly fall, and both should stabilize within a few minutes. If the CO or O2 levels spike suddenly after the blower starts on a warm air furnace, it is a sign the heat exchanger is compromised in some way. If the CO sensor oversaturates, immediately bring the probe into fresh air, and let the analyzer pump run until the CO displayed level is at or near zero.

Combustion Analyzer Maintenance

To keep your combustion analyzer ready for every heating season job, there are a few recommended maintenance tips. Always drain the analyzer water trap (if applicable) and check the dust filter regularly. When testing is complete, run the pump until CO, O2 and temperature readings return to ambient, removing any residuals from the sensors and analyzer. Also, when you’re powering the combustion analyzer down, ensure the probe has cooled to ambient temperature before inserting it into the carrying case. And finally, it is recommended that sensors be calibrated annually or as required by local regulations.

Let Your Combustion Analyzer Do the Work

A combustion analyzer is a powerful tool to help you keep fuel-fired heating appliances running efficiently and safely. Therefore, the biggest tip is that combustion analysis should be the first and last thing completed during any heating appliance repair. The outlined tips not only help ensure peak performance, but they help you prioritize safety and the use of best practices in your analysis procedures.
