Fieldpiece - HVAC School

Fieldpiece started with the idea that every HVACR professional in the field needs the best tools possible. That’s why we’ve produced a full family of rugged, feature-rich tools spanning meters to manifolds and vacuum pumps to recovery machines. Our wireless technology and Job Link® System are known as innovative HVACR tools to help the HVACR pro be on top of their game. Visit www.fieldpiece.com for information. Follow us on social media @fieldpieceproducts.

I remember seeing a Fieldpiece multimeter for the first time when I was in trade school. Since that time I can’t think of a time when I haven’t had a few Fieldpiece tools in my van or training room. Fieldpiece has always been an excellent partner and an integral part of the HVAC community and I’m honored to have them a partner of HVACRschool.com

Products We Love

Valve Core Removal Tools

Faster Recovery, Verified. Since every system and installation is different, we designed three valve core removal tools (VCRTs) to help HVACR technicians recover, evacuate and charge systems faster and with confidence, every time. Fieldpiece VCRTs represent a significant leap forward in valve core removal technology including options with a sight glass to verify the valve core is engaged before removing it and dual ball valves to protect connected gauges.

Hoses & Fittings

Quality Accessories for Quality Tools. Every tech needs a reliable set of hoses and fittings. We have made ours durable, long-lasting, and the same level of high quality you expect from Fieldpiece tools. Innovation is crucial in all our designs, and we didn’t stop at hoses. Triple ring crimping, low abrasion knurling, and mix and match hose tags are just the start.

SR47 Wireless Scale

The New Heavyweight Champion 13″ platform to fit larger tanks and integrated bumpers for increased durability Strong enough to hold a maximum load of 252 lbs Wireless remote control with LED backlight – can be stored inside the scale, and makes viewing data easy Industry-leading accuracy: ±0.03%rdg + 0.25 oz Lightweight. Total weight of scale and remote is ~7 lbs Water resistance can handle any job site Connects to the Job Link® System App with 1000′ wireless range and Digital Manifolds SM480V & SM380V Platform battery lasts 200+ hours – it can literally work all week if needed Easy-to-use raised power button now located at base of scale A2L compatible

DR58 Heated Diode Refrigerant Leak Detector

Since it’s a Fieldpiece, the DR58 Heated Diode Refrigerant Leak Detector is full of the features you need. It’s also designed to handle the abuse that most leak detectors can’t with an impact resistant IP54-certified body that fits easily in your hand.

DR82 Infrared Refrigerant Leak Detector

If you want to find leaks faster for your customers, try the Fieldpiece DR82 Infrared Refrigerant Leak Detector. Our newest detector can sniff out leaks at <0.03 oz/yr. That’s 20 times more sensitive than soap bubbles. This exceeds detection standards so you can quickly find and pinpoint leaks.

Vacuum pumps

As our latest innovations in the vacuum pump market, these workhorses cut evacuation time, so you can complete more jobs per day. They all feature four in-line ports as well as our RunQuick® Oil Change System that makes oil changes on the fly a breeze.

MG44 Wireless Vacuum Gauge

Like every piece of Fieldpiece hardware, the Wireless Vacuum Gauge (MG44) is built to make your work easier. It helps eliminate misleading measurements by allowing you to connect it at the system port – even those awkward, hard-to-reach spots.

MR45 recovery machine

MR45: The Fieldpiece MR45 recovery machine has onboard system monitoring that adjusts motor performance to handle liquid and run twice as fast on vapor. MR45 also steps up low voltage at the power plug to deliver full power to the motor where high voltage drop is a problem.

JL3KH6 Charge and Air Test Kit

Take a full system snapshot quickly and easily with the JL3KH6 Charge and Air Test Kit. This kit consists of 2 pressure probes, 2 pipe clamps, and 2 psychrometers in a quick access padded case. All measurements can be sent up to 1000’ away directly to your mobile device with the Job Link® System mobile app.

SM480V Refrigerant Manifold

SM480V: Knowledge, power and experience are packed into the SMAN® Refrigerant Manifolds. Years of feedback from A/C and refrigeration specialists is combined with Fieldpiece’s laser focus on continuous improvement to bring you the toughest, most advanced digital refrigerant manifold on the market.

SC680 Swivel Clamp Meter

Whether you’re working on small circuitry in mini-splits or on large commercial units, the new SC680 is packed with everything you need to install, service, and troubleshoot any HVACR system.

JL3KM2 Job Link® System Manometer

The revolutionary JL3KM2 Job Link® System Manometer probes give HVACR pros the freedom to work the way they want to — unrestricted by hoses, so technicians get readings from optimal locations on every system, every time.

HVAC School – For Techs, By Techs

Real training for HVAC ( Heating, Ventilation, Air Conditioning and Refrigeration) Technicians. Including recorded tech training, interviews, diagnostics and general conversations about the trade.

In this short podcast, Bryan talks about evaporator coil placement based on a question submitted by a listener, John. Evap coil placement differs in furnace applications versus air handlers.

When we use air conditioners with furnaces, we usually put evaporator coils on the positive side to protect the heat exchanger from rusting out during the summer (due to condensation and the chemical reactions that can occur with the metal heat exchanger). However, when it comes to air handlers, they’re usually on the negative side. The coil is usually on the negative side of a fan coil or air handler because it keeps the blower motor cooler (though that doesn’t make a huge difference in terms of performance).

The HVAC system will lose fewer BTUs to leakage when the coil is on the negative side, which is better for energy efficiency; those BTUs can reach the conditioned space rather than the closet, garage, or wherever it is stored. Pulling air over the evaporator coil on the negative side, however, could potentially lead to greater turbulence.

We run into challenges with evap coil placement on gas furnaces when we have dual fuel systems (a heat pump and furnace working together). You can’t run gas heat over a heat pump coil due to the high head pressure, so a parallel setup would avoid the risks of high head pressure (downstream) or rusted-out heat exchangers (upstream).
