The HVAC PROTech® TechTalk™ Forums are the parent site to the Digital Zeus™ Blog. The Forums were developed for, dedicated to and operated by HVAC/R & Controls technicians. The Forums are completely independent of financial reliance on any entity in the industry. We are fully self supporting. The boards are comprised of 100% verified professional HVAC/R & Controls technicans, installation technicians, business owners, and Instrument OEM representatives.Talk to other technicans - business owners - developers and designers of the Tools & Instruments we use - but if you wanna talk to the home owners about how to replace their blower motor, or discuss with them the reasons for your pricing structure - you’ll need to go somewhere else. Home owners and equipment owners are not permitted inside the Forums front page.Which brings us to why we have developed Digital Zeus™. Being 100% professional members only is a great thing, our discussions are unrestricted technically and financially because of it, but it has it’s down side as well. In order to maintain this level of membership, it is also necessary to prohibit Google and Yahoo spiders from researching content of the site - subsequently alot of qualified techncians and members of the trade don’t know we exist. The Zeus Blog provides a vehicle to allow the spiders to research limited excerpts extracted from the HVAC PROTech® boards discussions - put them in front of the guys, like us that know what to do with them.The HVAC PROTech® TechTalk™ Forums are also the parent site of the HVAC PROTech® Technical Archives, at our dotorg domain. The largest collection of technical data, files, html and A/V clips dedicated exclusively to the HVAC/R & Controls trades available on the internet - but like our boards, membership and access to this data is restricted and not permitted without verified membership to the HVAC PROTech® TechTalk™ Forums.An exclusive feature of the Forums is our member FieldTest Evaluation boards. our members are provided with some of the newest most advanced instruments available to the trade today. They keep them for two weeks, use them and then write extensive evaluations based upon their opinions of the capabilities of the instruments. Try before you buy - get unbiased, accurate reports of how these instruments actually perform in our environments - not what the OEM says they will do, but what we know they will do.

Wayne Sirley Heat Pump Guru- TROUBLESHOOTING HEAT PUMP SYSTEMS…INDOOR / OUTDOOR TEMPS VS SUPERHEAT W/ FIXED ORIFICE SYSTEMS June 8, 2008..If you look at a superheat charging chart for a fixed orifice system, you quickly see the required superheat varies with outdoor and indoor conditions. As the outdoor temperatures vary, so does the required superheat…pretty much the same relationship for indoor temperatures. Why? The net force pushing liquid through the metering device is the difference [...]
- TROUBLESHOOTING HEAT PUMP SYSTEMS…R-22 VS R-410A April 18, 2008Unless you’ve been living under a rock for the past several years, you know R-22 is on the way out and R-410A appears to be the manufacturer’s weapon of choice for heat pump and comfort cooling equipment. If you’ve already encountered a 410A system and had a less than pleasant experience, possibly attempting to correct [...]
- TROUBLESHOOTING HEAT PUMP SYSTEMS…OPEN CONTROL VOLTAGE CIRCUITS April 16, 2008One of the more frustrating and difficult situations with heat pump diagnostics is open circuits in the control wiring. There is a logical process to follow when attempting to locate the failure…
- TROUBLESHOOTING HEAT PUMPS SYSTEMS…REFRIGERANT LEAK DETECTION DEVICES April 15, 2008No doubt, my most frustrating service issue has been locating refrigerant leaks. And I’ll be the first to admit it was due to my own ignorance, from simply not doing a little research. I started out with a cold sensor technology electronic detector, bought a second cold sensor electronic detector and eventually concluded electronic detectors [...]
- TROUBLESHOOTING HEAT PUMPS…DIAGNOSING PSC MOTORS April 13, 2008A common failure with residential equipment condenser and blower motors is not actually the motor, but the run capacitor. Probably the majority of the time, the capacitors fail “open”…the motor can’t develop the necessary torque to actually begin rotation. So, it justs sits in a “stalled” condition, pulling above normal amps…the video gives some thoughts [...]

- 523 556 560 Temperature Measurement July 4, 2008The Pt100 temperature probe on the Testo 500 series refrigeration instruments has been carefully designed to work under a wide range of applications while providing the fastest temperature response in the industry. The platinum based 4 wire construction of the sensor has exceptionally low mass and is shielded from electrical interference from ghost voltages or static electricity [...]

- Getting the most from your Testo 330 or 327 February 4, 2008Some thought on combustion testing. When performing a combustion test, one of the most important concepts to understand is stability of the combustion process. If the combustion process is not stable, it is not safe. Once a flame is established, the burner should quickly reach study state operation and not be affected by factors external to it. While [...]
- Why Test with Digital Instrumentation February 2, 2008Why test? Making and interpreting measurements is a crucial part of any job involving service, installation, design verification, engineering, or factory support of HVAC/R equipment. When it comes to verifying proper operation of the installed equipment it is critical that measurements made in the field are just as accurate as those made the laboratory. At Trutech we [...]

Our new generation of the Testo line of refrigeration system analyzers (RSA’s) will continue to change the way the HVAC/R world troubleshoots, commissions and services AC & refrigeration systems. Although the first generation of refrigerant products was highly [...]

..as a senior member at HVACPROTech.com, I can vouch for the veracity of the above site description. Every member has the freedom to voice their opinions, whatever they might be, and debate the opinions of others. So long as one keeps his tone civil and professional, it’s a “no holds” barred forum.
And the amount of available “wisdom” from the members and archives, free for the asking, is virtually unimaginable. Got a question? Someone there will likely have an answer…and if not, someone will assist you in finding one.
Need to wind down from the long day? Front Porch Forum generally has some funny stuff posted by some members with strange names: Evil Gopher, Mainiac, Subcool2, Jaybird HVACGod..to name a few…and if it ain’t all that funny, it’s just enjoyably reading BS…
There is a dynamic brotherhood at ProTech you likely won’t find anywhere else. I discovered the site almost two years ago, purely by accident…I was immediately made to feel right at home, and it has been “home” ever since. All those other places are just “question and answer” corners…
