The HVAC Profession has advanced 1000 fold with MQ which continues to get better and better. My techs are much more productive with MQ. The best feature we all like is the NON invasive mode. It has been a game changer reducing refrigerant loss when connecting gauges during PMs. The use of probes instead of hose to gauge also greatly reduce loss. The EPA should recognize MQ in this regards. Reduce weight of tools on RTUs is another note worthy benefit. We just need a tablet that is direct sun readable for us old folks

Great discussion and info. Thank you, Jim and Ty. We need more like this.

Don't be afraid of that something is going to change in this business. It is.Very good information and a lot of knowledge.

The fundamentals are the best place to improve. It is so easy to gloss over something basic as rudimentary without fully mastering the concept or connecting it into a larger working model. Every athlete operating at a high level trains and doubles down on fundamentals because that’s where the 1% improvements come from day after day.

I’m not an HVAC technician. I just repair and maintain my own HVAC equipment. There’s nothing wrong with using automated tools, especially when they produce better results. I’ve never even used an analog manifold gauge set. My Testo Smart Probes are more accurate and not subject to the arithmetic errors people tend to make. I’m also lazy and would prefer not to have to continuously monitor two pairs of measurements and do subtraction in my head. However, I do own a set of analog manifold gauges and thermocouples in case something ever happens to my Smart Probes. My issue with this as an industry outsider is I don’t think someone who is incapable of calculating superheat and subcooling has a good enough grasp of HVAC fundamentals to be out in the field working on jobs alone. Someone who can enter numbers into TurboTax and produce a correct tax return but doesn’t understand accounting principles isn’t an accountant and shouldn't represent themselves as an accountant. Someone who can use measurement equipment but doesn’t understand what the measurements mean isn’t an HVAC technician. It's a bit ironic that an industry notorious for insisting DIYers are too incompetent to go anywhere near HVAC equipment apparently has technicians working within it who would be lost without a cell phone app to do the thinking for them. I’d be pretty irritated if I called for an HVAC technician, and the contractor charged me $100+ per hour for someone so incompetent they have to call tech support to figure out their probes are swapped. But don’t get me wrong. If a cell phone app can be made foolproof enough that someone who doesn’t understand HVAC fundamentals can use it to diagnose problems as well as a competent technician, I’m all for it. As a consumer, I like the idea of paying mechanic prices for technician results. For the individual doing the work, it’s a bit sad they are deprived of the joy of understanding, but that’s not my problem. Great video, by the way. I enjoy listening to these kinds of discussions between people well practiced in their field. I've learned a lot from both of you.

👍🏻👍🏻👍🏻👍🏻

need to learn how to do calculations manually before using computers/phones. otherwise it is like teaching kids to just use a calculator instead of how to do arithmetic by hand first. continue on this path and we'll be living in idiocracy soon enough.
