In this short podcast episode, Bryan shares his top tips for fighting boredom at work. You can use these tips to help you get out of a rut if you don\u2019t feel productive or get bored easily.<\/p>\n

\u00a0<\/p>\n

The first tip is to see the art or creativity in your work. Even in the HVAC industry, there are plenty of opportunities for artisan skills and craftsmanship. When you see your work as an art that you need to refine, especially in terms of duct strapping and brazing, it\u2019s easier to get engaged in your work and feel proud of it.<\/p>\n

\u00a0<\/p>\n

Another way to stop from getting bored is to do more things that challenge you. Being constantly challenged and being out of your comfort zone keeps you interested and can even spark a new passion.<\/p>\n

\u00a0<\/p>\n

Pursuing mastery allows you to focus on one particular skill or subject to become an expert. When you master a skill, you also become a marketable job candidate and can carve out a niche within your organization. Mastery is about going deep rather than wide, and more people will feel enriched by working towards mastery than others.<\/p>\n

\u00a0<\/p>\n

If you\u2019re a social person, finding a community can keep you from getting bored. When you have a community, you will be around people who have the same interests and experience the same challenges as you. So, you won\u2019t get bored from feeling alone.<\/p>\n

\u00a0<\/p>\n

Mentorship is another way to rekindle your passion. When you choose to invest in and guide less experienced people in the trade, you can feel a renewed sense of purpose in your work.\u00a0<\/p>\n

\u00a0<\/p>\n

And if you\u2019re REALLY bored, you can change everything up entirely and try something new.<\/p>\n

In this podcast episode, Bryan goes through the addendum to the book Review of Vacuum for Service Engineers<\/em>. He and Jim Bergmann had the honor of revising the latest edition in 2020. You can get the latest edition of Review of Vacuum for Service Engineers<\/em> from TruTech Tools HERE<\/a>.<\/p>\n

\u00a0<\/p>\n

Pulling a Schrader core before evacuation makes a big difference in the speed of the evacuation. You can use a core remover tool to pull the cores when the system is NOT pressurized.\u00a0<\/p>\n

\u00a0<\/p>\n

There are three common types of ports to access the system: the Schrader core, high-flow core (CoreMax), and the multi-position service valve. You can mid-seat the multi-position service valve for high flow, but you need to remove or depress cores on the other two port types. (You must use a special CoreMax CRT to remove high-flow cores.)<\/p>\n

\u00a0<\/p>\n

Three factors limit the speed of evacuation: the conductance speed of the pump, of the connecting hoses, and of the system. The hoses and manifold can severely impact evacuation. TXV and piston metering devices have short orifices and have very little impact on the evacuation time; on TXVs and EXVs, the valve should be fully open.<\/p>\n

\u00a0<\/p>\n

When pulling a vacuum, make sure the vacuum pump works properly and has clean oil. Once you know that the pump is working, only pull on a tight system (no leaks) and make sure the seals are in good shape.\u00a0\u00a0<\/p>\n

In today\u2019s short podcast, Bryan discusses electric heat, how we use it in our work, and what it does.<\/p>\n
\u00a0<\/p>\n
Also called heat strips or heat elements, electric heat is a supplemental heat source that we usually see on heat pumps. We generally see them in fan coils within a cartridge or a kit at the top of an air handler. However, not all systems have backup heat.<\/p>\n
\u00a0<\/p>\n
We want to avoid running electric heat as much as possible because it is inefficient. There is almost nothing we can do to make heat strips more efficient; they will usually yield around 3.41 BTUs per watt.\u00a0<\/p>\n
\u00a0<\/p>\n
We usually only run electric heat when a heating system can\u2019t keep up with the heat loss. However, the electric heat often runs more often than it should, which can cause inefficient conditions. You can avoid inefficient conditions by programming the thermostat properly.<\/p>\n
\u00a0<\/p>\n
If you reduce the voltage on the heat strips, the less heat they will produce. Current ratings also differ between 208v or 240v applications. When you have more voltage, you\u2019ll have more current as well.\u00a0<\/p>\n
\u00a0<\/p>\n
In some municipalities, you may have to use a thermostat that keeps heat strips OFF unless the temperature is below a certain value, often 40 degrees. Your electric heat should also be the last resort for a system.<\/p>\n
\u00a0<\/p>\n
Heat strips also help with heating when a heat pump is in defrost. The defrost board backfeeds the electric heat. These heat strips are also often designed with an interlock that forces the blower on whenever the electric heat is on (but not the other way around).<\/p>\n
\u00a0<\/p>\n
Bryan also discusses:<\/p>\n
\n
Kilowatts and electrical ratings<\/li>\n
Wiring and relays<\/li>\n
Wire sizing<\/li>\n
Furnace-to-heat-pump conversions<\/li>\n
Possible hazards<\/li>\n<\/ul>\n

Trevor Matthews comes on the podcast to discuss his newest project, Refrigeration Mentor. Refrigeration Mentor uses Trevor\u2019s experience as a trainer and field technician to guide others in their careers.<\/p>\n
\u00a0<\/p>\n
Trevor\u2019s goal is to help commercial refrigeration technicians grow and become more confident in their skills. He wants them to become the best technician they can be, and he believes that mentorship is one of the things that make our industry great. Mentorship can help people advance their careers, sharpen their skills, and ease their anxiety about work.<\/p>\n
\u00a0<\/p>\n
When we share knowledge, we bring value to the technicians. That value extends to the customer when technicians are more confident in their work and do better jobs. A good mentor has a commitment to doing quality work within the trade but will make their mentees feel comfortable to admit what they don\u2019t know.<\/p>\n
\u00a0<\/p>\n
Mentors can also help their mentees develop a solid work-life balance that helps mentees be present to their jobs and<\/em> their families. The mentor\u2019s job is to help their mentees reach their goals, whether that\u2019s learning a new skill, entering a leadership role, or even starting a business.\u00a0<\/p>\n
\u00a0<\/p>\n
Trevor also wants to help business owners or managers strengthen their teams. He believes that a dynamic culture and a strong emphasis on training will help a business (and the industry as a whole) grow. His mentorship approach comes from strengthening technicians, businesses, and the industry from the heart.<\/p>\n
\u00a0<\/p>\n
Trevor and Bryan also discuss:<\/p>\n

In this podcast, Ben from HAVEN IAQ, Kaleb, and Bryan discuss how to control indoor air quality and take meaningful, accurate measurements.<\/p>\n
\u00a0<\/p>\n
HAVEN is a platform that offers hardware and software delivered to a homeowner through an HVAC professional. HAVEN\u2019s goal is to give its customers a healthier, more comfortable home using IAQ solutions.\u00a0<\/p>\n
\u00a0<\/p>\n
The hardware (controls, etc.) works with the HAVEN software to give customers and contractors data about IAQ and the performance of the HVAC equipment. Right now, you may install up to two HAVEN controllers and one monitor per zone to help control equipment and monitor the air content.\u00a0<\/p>\n
\u00a0<\/p>\n
Air sampling occurs every hour, whether the HVAC system is running or not. Customers can learn to control their ventilation habits to address acute events (e.g., a spike in humidity from cooking), which only result in short-term IAQ problems. However, contractors can use the air sampling data to develop solutions for chronic events (e.g., constant high humidity).<\/p>\n
\u00a0<\/p>\n
Solutions, even simple filtration ones, are best left to the contractors to figure out. The integration of most IAQ products requires some degree of design and planning. HAVEN products do NOT provide plug-and-play solutions. While \u201cdemand\u201d solutions can introduce outdoor air to prevent a viral problem, you could introduce a moisture problem without proper planning.<\/p>\n
\u00a0<\/p>\n

Ryan Gorman comes on the podcast to discuss the differences between a college education and early career opportunities in the skilled trades.\u00a0<\/p>\n
\u00a0<\/p>\n
Many parents feel pressured to send their children to college and encourage them to get a four-year degree. Despite what society may lead us to believe, there is no shame in thinking that college may not be suitable for you or your child; the skilled trades have many opportunities for people to learn throughout their lives and make a good living.<\/p>\n
\u00a0<\/p>\n
In many cases, parents may see college as \u201ca ticket to the starting line.\u201d Unfortunately, college tuition has skyrocketed over the years, and a good ROI is not guaranteed. Instead, a career in the skilled trades can allow a person to develop hard skills and land a well-paying job at a young age. As the skills gap widens, young people who learn skills make themselves attractive to employers and increase their earning potential.<\/p>\n
\u00a0<\/p>\n
Children and teenagers who want to become engineers may actually prefer a trades career where they get to work with their hands. The path to the trades is less expensive than getting a four-year degree and may prove more fulfilling in the long run. Internships, small businesses, and trades careers are viable paths for young people; we don\u2019t present these possibilities at a young age, but they are worth considering for people who may not benefit from college.<\/p>\n
\u00a0<\/p>\n

Jason Obrzut comes on the podcast to discuss A2L refrigerant facts. Jason is a member of AHRI\u2019s Safe Refrigerant Transition Task Force and author of the RACT manual.<\/p>\n
\u00a0<\/p>\n
ASHRAE designates refrigerants into categories based on toxicity (A or B) and flammability (traditionally 1, 2, and 3). So, the new A2L designation indicates that a refrigerant is relatively non-toxic but has a flammability value between 1 (low) and 2 (moderate). While propane (R-290) is a good refrigerant because it is natural and has low toxicity, it is very<\/em> flammable (A3).\u00a0<\/p>\n
\u00a0<\/p>\n
Future refrigerants will likely fall under the A2L designation; the mild flammability will probably be the tradeoff for efficient, low-toxicity refrigerant with a low environmental impact. However, A2L refrigerants cannot<\/em> be vented, even despite their low GWP. We also cannot use these refrigerants in retrofits.<\/p>\n
\u00a0<\/p>\n
A2L refrigerants will likely become much more prevalent around 2023 as HFC refrigerants phase down. The phase-down period will be specified shortly, and it will begin with a 10% reduction; the specific parameters of the phase-down have yet to be set.\u00a0<\/p>\n
\u00a0<\/p>\n
When working with A2L refrigerants like R-32, you can expect little to no change in how you work on equipment if you\u2019re already employing the best practices. Sizing and capacity will hardly change in the residential market. In the commercial sphere, these systems still look and operate quite similarly to current units.<\/p>\n
\u00a0<\/p>\n
Jason and Bryan also discuss:<\/p>\n
\n
Refrigerant detection systems (RDS)<\/li>\n
Flowing nitrogen and other best practices<\/li>\n
Non-A2L HFC alternatives<\/li>\n
Left-handed threads<\/li>\n
Non-standard safety practices<\/li>\n

In today\u2019s podcast, Bryan and some Kalos employees discuss how to deal with difficult bosses and coworkers in HVAC\/R work.<\/p>\n
\u00a0<\/p>\n
Whether your coworkers have anger issues, are careless, or are miserable people, you don\u2019t want that negativity to affect your job satisfaction. Addressing the behavior may likely help, but you don\u2019t want to attack the other person. The key to dealing with difficult coworkers is to communicate boundaries respectfully with the goal of improving the work environment. Boundaries are also important when dealing with sarcastic people or those who make inappropriate remarks.<\/p>\n
\u00a0<\/p>\n
Any work environment with lots of people is bound to have cliques and tribes. You\u2019re best off not getting involved in any of that drama; the best thing you can do is be kind whenever you have the opportunity. Nepotism may also fall under tribal behaviors, and it may cause you to rethink your future with a company.<\/p>\n
\u00a0<\/p>\n
On the leadership side, micromanagers can be frustrating\u2014doubly so if your boss also happens to be condescending. If you have micromanager tendencies, try setting clear objectives and give your technicians room to develop. (If you\u2019re on the receiving end, talk to your boss about bigger-picture objectives to cut down on micromanagement.)<\/p>\n
\u00a0<\/p>\n
Learning is all part of working in the HVAC\/R field, but you may encounter friction with bosses who won\u2019t invest in learning or coworkers who refuse to learn new things. Try to have productive conversations with these people. If you\u2019re talking to a boss who doesn\u2019t invest in training, try to communicate your professional and educational needs. If you have a stubborn coworker or helper who doesn\u2019t want to learn, try to help them understand the new material by using similes and metaphors.<\/p>\n
\u00a0<\/p>\n
We also discuss:<\/p>\n

In today\u2019s podcast, Ed Janowiak comes onto the podcast to talk about the ACCA manuals. Ed started off in the field and has recently become the new Manager of Design Education at ACCA. You can follow him on Snapchat (skinnyed).<\/p>\n
\u00a0<\/p>\n
ACCA (Air Conditioning Contractors of America) is responsible for publishing and setting the standards in all of the books we use for residential and light commercial HVAC work. (Residential work typically encompasses Manuals J, S, D, and T).<\/p>\n
\u00a0<\/p>\n
The manuals can be very math-heavy. Many software programs have come on the scene to help automate the math to some degree, but the manuals will still remain relevant for years to come. The ACCA manuals offer guidelines for predictable results, and much of a technician\u2019s success will come down to how well they understand the order of operations.<\/p>\n
\u00a0<\/p>\n
In our trade, we have developed rules of thumb that help us with sizing and load calculations. However, those won\u2019t work all the time, and the predictability element is lost. The ACCA manuals exist so that you can complete your calculations, sizing, and equipment selections with some degree of rhyme and reason.\u00a0<\/p>\n
\u00a0<\/p>\n
ACCA updates the manuals on 5-year cycles; the manuals require periodic updates to keep up with new climate trends and new equipment as it hits the market. The information in the manuals is not 100% accurate and is variable, but that is just a product of our ever-evolving industry and world.\u00a0<\/p>\n

In today\u2019s podcast, Bryan and Jesse talk about how technicians can talk about finances and money in the HVAC business.\u00a0<\/p>\n
\u00a0<\/p>\n
The first step for any successful business is to provide customers\/clients with a product or service of value. However, there must be a balance between providing something of value to customers and providing excellent customer service.<\/p>\n
\u00a0<\/p>\n
When starting an HVAC business, one of the biggest mistakes is making money the top priority. Money can only become a factor after<\/em> a business establishes the value of its services and communicates its value to its customers. There is no hard line for fair pricing, so the contractor and customer must communicate to establish a price tag and<\/em> the expectations for the work performed.\u00a0<\/p>\n
\u00a0<\/p>\n
That same mistake applies to employees who want raises or promotions. Employees may feel as though they are owed more for their work, but they must establish their value before they get a raise. Again, the goal is to avoid unmet expectations.<\/p>\n
\u00a0<\/p>\n
Profitability and value are not just important to the managers and bookkeepers of an HVAC business. Technicians are the ones who bring profitability and value to their organization. Labor is expensive, but it must be valuable if you want to turn a profit (either for the business or in the form of increased wages). Technicians can increase their value and profitability by mastering skills and learning unique practices (IAQ, duct design, etc.).<\/p>\n
\u00a0<\/p>\n
When a business becomes more profitable, it can invest in better training for its techs. It can also have more control over the customers it chooses to serve.<\/p>\n

In today\u2019s short podcast, Bryan explains the differences between sleeve and ball bearings. Techs often make some avoidable mistakes because they either don\u2019t know the difference between the two or don\u2019t notice the bearing type on their equipment.<\/p>\n
\u00a0<\/p>\n
On a basic sensory level, ball bearings tend to be louder than sleeve bearings. So, if you replace a sleeve bearing motor with a ball bearing motor, then excess noise may not indicate any problems after all. Lubrication is usually more consistent with ball bearings, and those bearings have a far smaller contact area than sleeve bearings.<\/p>\n
\u00a0<\/p>\n
Sleeve bearings don\u2019t usually last as long as ball bearings; they have a larger contact area and can burn out quickly, so they are more common on smaller equipment where they will experience less intense axial forces. Those sleeve bearings also aren\u2019t as effective as ball bearings in variable-speed equipment. When techs put in a motor speed control and don\u2019t pay attention to the bearing type, they may end up burning up the motor if it has sleeve bearings.\u00a0<\/p>\n
\u00a0<\/p>\n
To determine which type of bearings your equipment should use, you can take note of a few different things. Ask yourself if there are motor speed controls or any sort of motor speed variability. If the answer is yes, then you\u2019ll use ball bearings. If longevity is a concern, then ball bearings are almost always the ideal choice.<\/p>\n
\u00a0<\/p>\n
If nuisance noise and inexpensiveness are greater issues than longevity, then you\u2019ll be better off replacing a sleeve bearing motor with another sleeve bearing motor than a ball bearing motor.<\/p>\n<\/p>\n

In today\u2019s podcast, Trevor Matthews from Emerson talks about horizontal scroll compressors. Throughout the podcast, we refer to Bulletin AE4-1338 (R3). You can find that bulletin HERE<\/a>.<\/p>\n
\u00a0<\/p>\n
Horizontal scroll compressors are common in mobile applications, like buses and trains. They\u2019re shorter in height than other compressors, so they fit into tighter spaces and are ideal for transport refrigeration.<\/p>\n
\u00a0<\/p>\n
Scroll compressors are particularly susceptible to overheating, and you need some controls to protect your compressor from damage. To prevent overheating, scroll compressors require pressure relief controls. You can typically use an OEM high-pressure control to protect the system. A low-pressure cutout installed in the suction line can help prevent TXV failure and a wide range of restrictions.<\/p>\n
\u00a0<\/p>\n
Accumulators are especially important for horizontal scrolls in heat-pump applications. However, accumulators have a fine mesh screen that can become clogged easily. So, we highly recommend replacing your accumulator in the case of burnout, not reusing it.\u00a0<\/p>\n
\u00a0<\/p>\n
Refrigerant migration prevention is a little more complicated than in refrigeration systems with other compressors. You can use a crankcase heater, but you may also need a check valve in the discharge line and a liquid line solenoid valve. We don\u2019t use pump down cycles for refrigerant migration; we use them to prevent the gas from moving backward and reversing the scroll.<\/p>\n
\u00a0<\/p>\n
When commissioning a three-phase compressor, you need to put your gauges on before<\/em> starting the system up. You may also consider using a phase rotation monitor to make sure the scroll compressor is rotating in the correct direction (usually clockwise but not always).<\/p>\n

In today\u2019s short podcast, Bryan discusses buck-boost (auto) transformers and what they do.<\/p>\n
\u00a0<\/p>\n
Autotransformers are not automatic; the \u201cauto\u201d prefix comes from the fact that autotransformers only have one<\/em> inductive winding. That winding is shared by the primary and the secondary, so it is not an isolation-type transformer. These transformers run current through the same winding used for induction.\u00a0<\/p>\n
\u00a0<\/p>\n
Buck-boost transformers rise or decrease voltage. When the transformer \u201cbucks,\u201d it decreases voltage from primary to secondary, and a \u201cboost\u201d increases the voltage from primary to secondary. In other words, a \u201cboost\u201d is a step up, and a \u201cbuck\u201d is a step down on a small scale.<\/p>\n
\u00a0<\/p>\n
You can only wire these transformers if you use the manufacturer literature. There are many types of autotransformers, and you need to know the exact setup for your transformer\u2019s specific design. Generic diagrams will usually not suffice.<\/p>\n
\u00a0<\/p>\n
When sizing a buck-boost transformer, you must keep your start load in mind as well. As technicians, we might not be able to handle the specifics of sizing based on the start load, but it\u2019s still something to keep in mind.\u00a0<\/p>\n
\u00a0<\/p>\n
The \u201cbuck\u201d configuration of the buck-boost transformer is especially helpful in markets where the utility company tends to produce overvoltage. Our specific setup uses the Micron J750A1EB1A02, which you can learn more about on YouTube HERE<\/a>. The \u201cboost\u201d configuration helps when a motor doesn\u2019t get enough voltage from the utility source.<\/p>\n
\u00a0<\/p>\n
Before you buck or boost the voltage, remember to account for both sides of the equation; if the utility changes the voltage, you still want to be within range.<\/p>\n

The HVAC and IAQ fields intersect in the areas of thermal comfort, humidity, building pressures, ventilation, filtration, and source control (which pollutants are present, where they come from, and how we can remove them).<\/p>\n
\u00a0<\/p>\n
John does not believe in throwing IAQ products at a problem. He believes in a thorough analysis of the structure to present the customer with solutions tailored to their home and needs. Ideally, John would like to see technicians take a process-oriented approach to indoor air quality: investigate, analyze, and quote. He believes in the power of slow, complete diagnosis, including listening to customers\u2019 complaints. Remember, they\u2019ve been living in the structure and can tell you about the issues they\u2019ve noticed in their home and their health concerns.<\/p>\n
\u00a0<\/p>\n
When you analyze a system, you may have to do additional testing beyond a visual inspection. Sometimes, you can\u2019t always find fungal growth or must call an expert to test for asbestos. The key to practicing IAQ is to be open-minded and seek help from experts beyond your field.<\/p>\n
\u00a0<\/p>\n
While IAQ solutions can be expensive, they can be well worth it for many customers. Try not to pass your own judgment on the prices; after all, you are performing quality work and could save your customer money on medical bills.<\/p>\n
\u00a0<\/p>\n
John also explains:\u00a0<\/p>\n

In today\u2019s podcast, Scott Krasman from TZOA, Andrew Greaves, and Kaleb Saleeby join Bryan for a conversation about mental health in the trades. We have a greater awareness of mental health than we ever did before, and although some of us may make fun of the topic, it is something we should focus on as HVAC technicians and business owners.<\/p>\n
\u00a0<\/p>\n
\u201cToxic\u201d is a common buzzword these days, but it\u2019s relevant here. A work environment with toxic traits will wear you down over time as you are exposed to disillusioned or selfish journeymen or senior techs at work who disregard your wellbeing and development. Sadly, these behaviors often come from low morale and projection.<\/p>\n
\u00a0<\/p>\n
HVAC industry leaders can take strides by promoting a culture of inclusiveness and encouraging conversations about mental health. There is also an element of personal responsibility within techs to acknowledge if something is wrong and to have honest conversations with their leaders. As techs, we need to know when to ask for help if we need it. Leaders must also look at themselves and address their own mental health issues so that they don\u2019t project their issues onto others.<\/p>\n
\u00a0<\/p>\n
As techs, we need self-awareness and intentionality to address our mental health. We need to understand what\u2019s going on with ourselves (even if we need to talk to mental health professionals) so that we can take steps to get the support we need.<\/p>\n
\u00a0<\/p>\n

In today\u2019s podcast, Jim Bergmann talks about troubleshooting the entire system. He takes a holistic approach to the art of troubleshooting, NOT just an equipment-centered one.<\/p>\n
\u00a0<\/p>\n
According to NIST, the most common HVAC system problems are duct leakage, refrigerant undercharge, and oversized equipment (often for undersized ducts).<\/p>\n
\u00a0<\/p>\n
Duct leakage heavily affects the envelope; the equipment only plays a part in conditioning a space. As such, you will want to seal up holes that lead to unconditioned spaces, such as behind the thermostat, to avoid creating negative pressure. When there is that negative pressure, especially close to the thermostat, the home could be at risk of over-cooling.<\/p>\n
\u00a0<\/p>\n
We check that the filter is clean, but we rarely ever question if the filter is good enough for the home. If the filter does not do a good job of improving air quality, you may consider changing the filter type or reducing the air velocity.<\/p>\n
\u00a0<\/p>\n
Even though we take temperature and pressure readings from the outdoor units, we sometimes fail to look for obvious non-equipment issues. Some yard cleanliness issues, such as vines or pet urine on the condenser, simply get overlooked. These issues may result in high head pressure and are usually more likely than refrigerant overcharge.<\/p>\n
\u00a0<\/p>\n
Overall, many systems have issues that can be solved with solid visual inspections and corrective measures beyond the equipment, such as addressing duct leakiness. When you troubleshoot better, you bring in more revenue for the company and increase your likelihood of getting a raise while keeping your customers satisfied.<\/p>\n

In today\u2019s podcast, Steven Rogers joins Bryan to talk about measuring total system airflow.<\/p>\n
\u00a0<\/p>\n
Fluid measurement is NOT restricted to liquids; a fluid is anything that flows, including liquids and gases. In HVAC, we deal with both of them, but airflow is strictly limited to the flow of gas. The airflow we experience in HVAC is exclusively turbulent flow, NOT truly laminar flow.<\/p>\n
\u00a0<\/p>\n
Total system airflow is difficult to measure directly; we can use flow hoods, but they have their limitations, especially on systems that have multiple returns. So, we measure pressures that give us clues about the airflow tendencies.<\/p>\n
\u00a0<\/p>\n
One of the most recognizable measurements is static pressure. Many factors can contribute to poor static pressure, including dirty filters and poorly designed supply and return plenums.\u00a0<\/p>\n
\u00a0<\/p>\n
All measurements that you use to calculate static pressure will require an average. You take readings at multiple points of the duct, so you need to calculate an average value, whether you\u2019re using static pressure tips, a hot wire anemometer, or a vane anemometer. Measurements are also particularly difficult to take in the supply registers, as there are almost no runs of straight duct.<\/p>\n
\u00a0<\/p>\n
Recently, the TrueFlow grid has come on the scene to make airflow measurement easier. The grid relies on torque and RPM data to determine the total system airflow. The TrueFlow grid slides in where the filter goes and measures the total system airflow. The grid works with an app that considers the system tonnage to let you know how good or bad the airflow is.<\/p>\n

In today\u2019s short podcast, Bryan explains how growth happens in an HVAC\/R career. He also gives tips to get \u201cunstuck\u201d if you feel like you aren\u2019t moving forward.<\/p>\n
\u00a0<\/p>\n
You won\u2019t move forward if you haven\u2019t set a goal to move forward. Making a \u201cvision board\u201d helps you determine what matters in your life, and it helps you clarify what you\u2019ll need to do in order to achieve your life goals. That way, you can use your career to help achieve those goals and see whose support you need.<\/p>\n
\u00a0<\/p>\n
Having a growth mindset and a lifelong learning mindset is essential for success. The growth mindset will help you deal with the \u201cgrowing pains\u201d of advancement (such as occasional failures). People with positive attitudes also tend to see more possibilities for their future careers. On the other hand, negative people are likely to idle in their careers.<\/p>\n
\u00a0<\/p>\n
You also want to surround yourself with people who will bring out your best. It\u2019s great to be around people who challenge you, have positive outlooks, and are happy for you when you make progress. Moreover, you want to be the person who is authentically excited when other people succeed and do good work. Also, try not to burn bridges with others.<\/p>\n
\u00a0<\/p>\n
To advance in your HVAC career specifically, develop your hands-on skills. Think about it this way: are you merely doing your job\u2019s requirements, or are you working on yourself? Read through manuals and check out technical materials to become more literate with systems and do better work on them. Also, try to find a mentor who will help you grow. People skills are underrated in our industry but are critical for career advancement.<\/p>\n

In today\u2019s podcast, Bryan and a team of Mitsubishi Electric Trane HVAC US (METUS) managers (Mike Schaefer, Charles Miltiades, and Sly Grimm) discuss mini-split controls strategies.<\/p>\n
\u00a0<\/p>\n
Some contractors misunderstand what mini-splits are. Mini-splits CAN be ductless, but not all of them are ductless. Mini-split systems also have handheld controls, but those are not the only control options for mini-splits. Mini-split controls also come in wi-fi, wall-mounted, and wired varieties.<\/p>\n
\u00a0<\/p>\n
Another common misconception about mini-splits is that they do not work in the cold. While that used to be accurate, modern mini-splits can function well as heat pumps that integrate backup heat. That is especially when it is also tied into a ducted system.<\/p>\n
\u00a0<\/p>\n
A lot of thought goes into sensor placement, and contractors have many options as to where they can be placed. You can put wireless sensors in discreet locations, such as under the air return in the basement.<\/p>\n
\u00a0<\/p>\n
Lately, there has been a market shift towards a preference for multizone equipment, so the wireless controls help manage several units instead of just one; you can manage 30+ indoor units.<\/p>\n
\u00a0<\/p>\n
In general, homeowners are becoming more tech-savvy and are beginning to prefer tying all of their HVAC systems together and managing them all via one platform. As such, Mitsubishi controls can connect to smart home assistants, such as Alexa or Google. Mitsubishi mini-split controls also work with a cloud service that remembers data. However, a strong wi-fi system is necessary for these controls.<\/p>\n

In today\u2019s short podcast, Bryan discusses the key factors for system performance WITHOUT doing a deep dive into system commissioning. \u201cPerformance\u201d refers to system efficiency, capacity, air filtration\/cleanliness, longevity, and the ability to match the latent and sensible loads of a space.<\/p>\n
\u00a0<\/p>\n
System airflow is the main performance factor to consider. To determine proper airflow (CFM), consult Manuals S, J, and D to perform calculations. In general, the absolute lowest limit is around 275 CFM (in extreme dehumidification mode), and the highest limit should be around 525 CFM (in arid climates or at altitude).\u00a0<\/p>\n
\u00a0<\/p>\n
You can determine your CFM target after you set up your ECM motor in the design. Then, you can also check airflow indicators: total external static pressure and pressure drop across the filter. The best way to improve airflow is to reduce pressure drop across the filter and build a better return plenum. For improving overall system performance, make sure the ducts are appropriately sized.\u00a0<\/p>\n
\u00a0<\/p>\n
System charge is another important performance factor. There is a lot more to evaluating charge than checking the superheat and subcooling. If possible, it is a good idea to weigh the charge with a scale and see how it matches up with the line length.<\/p>\n
\u00a0<\/p>\n
In terms of long-term performance, the condenser\u2019s location and cleanliness are also vital. Overall, a condenser works best if it\u2019s in a slightly shaded area or on the north\/east side of a building. The outdoor unit should also have some clearance from bushes and walls. Make sure the condenser is positioned away from pool equipment, water softener discharge, and dryer vent discharge. The goal is to keep the outdoor unit corrosion-free and able to \u201cbreathe.\u201d<\/p>\n

与工作中的无聊作斗争——简短129

通过布莱恩·奥尔

在这段简短的播客插曲中，布莱恩分享了他在工作中战胜无聊的秘诀。如果你觉得工作效率不高或者很容易感到无聊，你可以使用这些技巧来帮助你摆脱常规。

第一个建议是在你的工作中看到艺术或创造力。即使在暖通空调行业，也有大量的工匠技能和工艺的机会。当你将自己的作品视为一种需要完善的艺术时，特别是在管道捆扎和钎焊方面，你会更容易投入到自己的工作中，并为此感到自豪。

另一种避免无聊的方法是做更多有挑战性的事情。不断接受挑战，走出舒适区，会让你保持兴趣，甚至能激发新的激情。

追求精通可以让你专注于某一特定技能或主题，从而成为专家。当你掌握了一项技能，你也会成为一个适销对路的求职者，并能在你的组织内开拓出一个利基。掌握是深入而不是广泛的，更多的人会因为努力掌握而感到充实。

如果你是一个社会人士，找到一个社区可以让你不感到无聊。当你有一个社区时，你将与那些和你有相同兴趣和经历相同挑战的人在一起。所以，你不会因为感到孤独而感到无聊。

指导是另一种重新点燃激情的方式。当你选择投资并引导经验较少的人从事这一行业时，你会在工作中重新感受到一种使命感。

如果你真的很无聊，你可以完全改变一切，尝试新的东西。

深呼吸：暖通空调系统中的呼吸危害 W1、W2和E 为什么委员会会破裂以及如何修复它们

制冷技术

毒液包冷凝器纯浓缩线圈清洁剂
毒液包装冷凝器清洁剂是一种高发泡纯浓缩液体，旨在解决最坚硬的土壤。专用混合清洁剂将液化严重嵌入油脂和污垢，以恢复传热和提高效率的盘管。

毒蛇冷凝盘和排水处理
Viper冷凝盘和排水管处理是一种可喷雾凝胶。它在集油盘、p型存水弯和排水管道上覆盖一层润滑膜，以改善流动性并防止未来土壤粘附。这种缓慢溶解的酶凝胶将比传统的片剂和条状物表现更好，更持久。

尼龙蓝垫圈-用于交流/R系统的螺纹密封胶
在连接核心工具、软管或真空计之前，在橡胶软管垫圈上滴一滴Nylog，可以确保在排空过程中不会发生粘合或泄漏。源自制冷级润滑剂。不硬化、不干燥的液体，与许多不同的基材紧密结合。通常，一滴Nylog在破裂前可以拉伸约三英尺。
