Electrical Myth - Wire Length Code - Short #155
October 18, 2022 11:00 - 12 minutes - 17.4 MBIn this short podcast, Bryan covers a common electrical myth about wire length and its relationship with the National Electrical Code. The NEC is concerned with safety—protecting buildings and people—but less so with making sure things work. Wire sizing is a common topic, and length is important because it can contribute to the voltage drop in a circuit. In many cases, we refer to the MCA (minimum circuit ampacity) to select an appropriate wire size. If you run more current through an u...
Why CO2 Matters w/ Trevor Matthews
October 13, 2022 11:00 - 39 minutes - 54.3 MBTrevor Matthews, the founder of Refrigeration Mentor, returns to the podcast to talk about why CO2 matters in commercial refrigeration and even HVAC applications. CO2 (R-744) has entered the residential HVAC sphere in some places around the world, though it hasn’t come to the North American markets yet. CO2 is one of the most eco-friendly refrigerants on the market, with a GWP of 1, and it’s very good at moving heat. However, CO2 has some challenges, including its low critical point and hi...
Electrical Basics
October 06, 2022 11:00 - 1 hour - 121 MBThis podcast is Bryan’s full-length electrical basics class for the Kalos technicians. He covers electrical theory and circuit basics. Volts, resistance, and amps all affect the behavior of electricity in circuits. These are also critical factors in electrical safety. Watts and kilowatts come from the multiplication of the volts and amps, though not every volt-amp does work; the power factor indicates how much work the volt-amps are actually doing. Some of the volt-amps are reactive (kVAR)...
Myth: Path of Least Resistance - Short #154
October 04, 2022 11:00 - 10 minutes - 14.3 MBIn this short podcast, Bryan debunks the myth that electricity only takes the path of least resistance. It is true that more current will typically take paths of lower resistance; it’s much easier for more electrons to flow through a path with lower resistance, which is consistent with Ohm’s law. Ohm’s law states that a circuit will have higher current with you have lower resistance so long as the voltage stays the same. In most cases, the voltage stays relatively constant; transformers...
Dehumidification in Shoulder Seasons w/ Nikki
September 29, 2022 11:00 - 58 minutes - 81 MBNikki Krueger from Santa Fe Dehumidifiers returns to the podcast to talk about dehumidification equipment and strategies in the shoulder seasons (spring and fall). The shoulder seasons (and the weeks leading up to them) are when many homeowners begin to notice moisture problems in their homes. HVAC units and dehumidifiers should have a king-queen relationship. The HVAC unit is the king and controls the bulk of temperature and humidity during the day, but the dehumidifier can take care of t...
Time Management - Short #153
September 27, 2022 11:00 - 15 minutes - 22 MBIn this short podcast episode, Bryan gives some quick tips for time management. You can save a lot of time by prioritizing what really matters and delegating tasks. One of the simplest but most effective ways to manage your time is to use a calendar. You can even apply the calendar to your personal life; you can get into a habit of scheduling important appointments, deadlines, and tasks. Google Calendar also allows other people to see and interact with your schedule, so it’s a great tool f...
Become a Better Mentor w/ Eric Kaiser
September 22, 2022 11:00 - 43 minutes - 60.6 MBEric Kaiser returns to the podcast to talk about how to become a better mentor. He explains the topic from the perspective of a mentor and a mentee. The goal of mentorship is to pass your knowledge on to someone else. When you give someone the knowledge to succeed in the HVAC/R trade, you move the trade forward and allow yourself to try new career opportunities when someone can replace you. Some of the most effective mentorship strategies establish the mentor as a guide rather than someo...
HVAC Measurement Types and Benefits
September 15, 2022 11:00 - 43 minutes - 59.4 MBEric Kaiser joins the HVAC School podcast to talk about HVAC measurement types and the benefits of taking each one. He also talks about point measurements and data trends. Point measurements include static pressure, voltage readings, and readings provided by gauges. We only take those measurements once. However, when you track those on several occasions over time, you can build data trends. Single-point measurements give us information about what is happening at the moment, but they don’t ...
Ventilation and 62.2 Intro & Rant w/ Genry Garcia
September 08, 2022 11:00 - 55 minutes - 75.8 MBGenry Garcia joins the podcast to give an intro to ASHRAE Standard 62.2. He and Bryan also share a nice rant about accountability in HVAC design. Standard 62.2 is the ventilation standard for low-rise residential buildings, which dilutes airborne contaminants like VOCs and CO2. Before coming up with a ventilation strategy, we need to assess the leakage rate of the building, such as via a blower door test. However, we also need to consider how bringing in outdoor air might negatively affect...
Pressure Enthalpy without Tears
September 01, 2022 11:00 - 47 minutes - 64.9 MBRACT manual co-author Eugene Silberstein joins the podcast to talk about the titular topic of his book, Pressure Enthalpy Without Tears. Pressure Enthalpy Without Tears is a book that introduces engineering concepts to HVAC technicians in a way they can understand and apply in the field. Enthalpy is a fancy way of saying “heat,” and we use it to refer to the total heat content (BTUs). The pressure-enthalpy chart shows the relationship between the refrigerant pressure and enthalpy in a s...
Total Heat of Rejection - Short #152
August 30, 2022 11:00 - 10 minutes - 14.1 MBIn this short podcast, Bryan talks about THOR, total heat of rejection. He explains what it is and why we should care about it when working on HVAC/R systems. THOR is another aspect of pressure-enthalpy calculations, along with net refrigeration effect (NRE) and total heat of compression. When we talk about system capacity, we’re often referring to heat absorbed in the evaporator coil (NRE). Heating is on the opposite side of the coin; when we bring heat into a home, we care more about ho...
Hard Start vs. Easy Start
August 25, 2022 11:00 - 1 hour - 108 MBMatteo Giovanetti from Micro-Air joins the HVAC School podcast to talk about the differences between a hard start and an EasyStart. Micro-Air’s “EasyStart” provides a soft start rather than a hard start. A hard start abruptly ramps up the voltage and current to the motor start; a soft start is a much gentler start that results from a gradual voltage and current increase on the start AND run windings. The EasyStart marks a paradigm shift in how we think about “saving” compressors. It att...
Heat of Compression - Short #151
August 23, 2022 11:00 - 8 minutes - 11.9 MBIn this short podcast, Bryan explains what the heat of compression is and why we should care about it as HVAC/R professionals. More heat is rejected in the condenser than absorbed in the evaporator coil, and that’s because the compressor adds heat. That added heat is called “heat of compression.” That heat does NOT contribute to the net refrigeration effect (NRE), as it doesn’t contribute to cooling. When we compress something, we increase the system entropy during that process. Entropy ...
Intro to ACCA Manual T
August 18, 2022 11:00 - 40 minutes - 56.5 MBEd Janowiak joins the podcast to introduce us to ACCA Manual T. Compared to other manuals, Manual T is one of the least-considered ACCA manuals. However, it’s the manual that advises us on how not to blow high-velocity air on people and has maintained the same standards since the mid-1900s. Unlike Manuals J, S, and D, Manual T is not recognized in code compliance. Manual T deals with air distribution; it helps us find out the throw and spread, which informs our ductwork design in Manual ...
Net Refrigeration Effect - Short #150
August 16, 2022 11:00 - 12 minutes - 17.2 MBIn this short podcast, Bryan explains what the net refrigeration effect (NRE) is and how it affects HVAC systems. The net refrigeration effect (NRE) is what happens in the evaporator coil. The evaporator is the heat absorber; as air passes over the coil, the cooler refrigerant within the evaporator absorbs that heat and boils. The NRE is the net energy change that occurs during that process. You can plot the NRE on a pressure-enthalpy chart. When air moves over the evaporator coil, there...
Systems Thinking - Gas and Combustion
August 11, 2022 11:00 - 54 minutes - 74.7 MBEric Kaiser returns to the podcast to talk about how we can use systems thinking to approach gas appliances and combustion in HVAC installation and service. Gas lines can be made of a few different materials, including black iron, copper, and CSST. These all have benefits, setbacks, and appropriate applications. For example, copper is common in propane (LP) systems but not natural gas. In coastal environments, galvanized pipe tends to be most common due to the increased likelihood of corro...
HVAC School Admin Discussion - Moderating a Successful Community
August 04, 2022 11:00 - 59 minutes - 81.5 MBSome admins from the HVAC School Facebook group join the podcast to discuss the art of moderating a successful community. Bryan is joined by Eric Kaiser, Ty Branaman, Michael Housh, and Neil Comparetto. A community based on a skilled trade gives people an inviting space to share information and ask questions. It’s also a space that allows people to practice how they present information. Groups also connect people across geographical locations, and we can get regional perspectives that chan...
Systems Thinking - HV / LV / Condensate
July 28, 2022 11:00 - 46 minutes - 64.3 MBEric Kaiser returns to the podcast to discuss high-voltage wiring, low-voltage wiring, and condensate assemblies as they relate to systems thinking. On the high-voltage side, the disconnect should be in a secure location, and it should be able to keep water out. The wires should be appropriately sized, have an appropriate level of tension, and should not be vulnerable to chafing or abrasion. Overall, best practices include using proper grommets and ensuring that you have a solid connection...
Systems Thinking - Copper & Line sets
July 21, 2022 11:00 - 33 minutes - 46.4 MBEric Kaiser returns to the podcast to talk about how copper, piping, and line sets play into systems thinking. Nowadays, we have to think about POE and PVE oil, and we need to design line sets in a way that assists with oil carry while preventing liquid refrigerant migration. The height of the evaporator relative to the condenser is a major factor to consider during the design phase. Especially when chases are run underground, we need to watch for possible threats to the copper. Water so...
Systems Thinking In HVAC w/ Eric K
July 14, 2022 11:00 - 53 minutes - 73.3 MBEric Kaiser joins the podcast to talk about systems thinking in HVAC. Systems thinking allows us to solve problems and address customers’ comfort holistically instead of focusing on just the equipment. The key to systems thinking is to think outside the appliance. System design plays a major role in performance. Duct design, drain placement, and equipment placement all matter, and we can only do so much to mitigate factors of poor design. We need to assess the building envelope and conside...
Logical Fallacies - False Cause & Strawman
July 07, 2022 11:00 - 42 minutes - 58.4 MBNathan Orr joins Bryan to talk about some logical fallacies, namely the false cause and strawman. They explain how those fallacies show up in the trade. It’s difficult to present arguments without using fallacies, but people tend to rely on fallacies to uphold extreme religious or ideological viewpoints or conspiracy theories. Fallacies are also often easier to communicate than nuanced science and data. “False cause” relates to the phrase “correlation does not equal causation.” It can be...
Tips for Learning in HVAC/R w/ Trevor Matthews
June 30, 2022 11:00 - 33 minutes - 45.6 MBRefrigeration Mentor founder Trevor Matthews returns to the HVAC School podcast to talk about personal development and training, including tips for learning in HVAC/R. When you’re looking at a problem in the field or in training, it pays to take a step back, cool down, and reevaluate your mindset. Trevor recommends thinking about the worst-case scenario and seeing how you can either prevent it or grow from it. It’s good to walk away for a little bit anytime you feel like you’re overanalyzi...
Threaded Connection Tips - Short #149
June 28, 2022 11:00 - 14 minutes - 20.7 MBIn this short podcast episode, Bryan shares some of his top threaded connection tips. He also clears up some confusion about connection types. Threaded connections include flare and compression-type fittings (like chatleff or Aeroquip fittings). The threads don’t actually make the seal; the pressure pushing the surfaces together is what makes a seal. Bryan doesn’t recommend putting traditional thread locks on flares, but refrigerant oil or mild assembly lubricants can help the flare com...
Giving Kids The Tools For Any Job They Want
June 23, 2022 11:00 - 53 minutes - 73.8 MBBryan explains how parents and educators can succeed at giving kids the tools for any job they want. This podcast was originally a presentation at the 2022 FPEA Florida Homeschool Convention. Jobs, careers, and vocations have changed a lot over the years. Even though those have changed over the years, parents still want their kids’ vocations to develop character, foster growth, and bring joy. While kids are young, parents can instill values of grit and diligence; however, parents have to o...
ERV & HRV - Short #148
June 21, 2022 11:00 - 11 minutes - 16 MBIn this short podcast episode, Bryan talks about ERV and HRV technologies, including their appropriate applications and limitations. HRVs are heat recovery ventilators (not to be confused with heat recovery units or HRUs), and ERVs are energy recovery ventilators. The main difference between these two lies in the type of heat they move; HRVs only move sensible BTUs, whereas ERVs move sensible and latent BTUs. As you bring air in from outside, you’re discharging roughly the same amount o...
Refrigerant Changes Coming & The Helix w/ Emerson
June 16, 2022 11:00 - 46 minutes - 63.9 MBRajan Rajendran and Jennifer Butsch from Emerson join the podcast to discuss the Helix and some refrigerant changes that are coming. Jennifer is the Director of Regulatory Affairs, and Rajan is the Global Vice President for Environmental Sustainability and former director of the Emerson Helix. Lately, there have been more environmental efforts to reduce greenhouse gas emissions, and plenty of large corporations have “net zero” initiatives. Sustainability requires a holistic, systemic appro...
Pilot Controls - Short #147
June 14, 2022 11:00 - 7 minutes - 9.89 MBIn this short podcast episode, Bryan talks about pilot controls. He talks about the old-school ignition systems on gas appliances and some similar pilot functions on residential A/C units and heat pumps. When we think about a pilot light on a gas appliance, we can think of it as a small standing flame that sits there ready to ignite the burner whenever gas is flowing. Pilot lights were necessary for old-school gas furnaces, and many of those pilot lights worked with a thermocouple. In many...
Ethics - Grit and Discipline
June 09, 2022 11:00 - 25 minutes - 35.9 MBBryan and Robert Orr continue their discussion about ethics by talking about what it means to have grit and discipline in business. They talk about what those characteristics look like in business and in life, and they mention some good books. Grit is a trait that can contribute to an ethical way of life; showing grit means that you follow through with a project until you get the results you want. Both physical and emotional grit are strengths, and those things tend to be more important th...
Ethics - Integrity
June 02, 2022 11:00 - 33 minutes - 46.4 MBBryan and Robert Orr talk about ethics and what it means to have integrity when running a family business. Robert is a lifelong tradesman who is a licensed construction contractor, and he has overseen the construction side of Kalos for many years. Robert initially started off at the Air Force Academy and realized that he didn’t feel that the military was right for him. While in Florida, Robert fell into the trades and learned both hard skills and ethics in the process. He started his own h...
Distributors and External Equalizers - Short #146
May 31, 2022 11:00 - 10 minutes - 14.3 MBIn this short podcast, Bryan talks about distributors and external equalizers and why we need to use them together. When older Carrier heat pumps (with pistons) would run in heat mode, the metering device would be outside. In those cases, the port on the liquid line would be on the opposite side of the metering device. So, you wouldn’t actually be measuring the liquid line pressure (high-side) if you measured it at that port while the system runs in heat mode. However, that pressure woul...
Center-Tapped Transformers - Short #145
May 24, 2022 11:00 - 11 minutes - 16.2 MBIn this short podcast episode, Bryan talks even more about sine waves and center-tapped transformers. Power is generated at the power plant when an energy source (such as steam) is used to drive a drive shaft. The resulting current can be mapped as sine waves, which actually represent points on a circle; there is a rotational magnetic field around stationary conductors, and the sine waves allow us to envision the positive and negative alternations as the rotation happens. Center-tapped t...
Beer & Power Factor - Short #144
May 17, 2022 11:00 - 15 minutes - 21.5 MBBryan describes the tricky concept of power factor and why we should care about it. He also compares power factor to a beer mug to make the topic easier to understand. Power is often represented on a sine wave, which is a curvy line that marks the state of electrical energy at different points on a circle. Power gets stronger and weaker, and it goes above and below the neutral line depending on the excess or deficit of electrons. Unity power factor refers to a power factor of 1, indicati...
Motor Speed Facts - Short #143
May 10, 2022 11:00 - 9 minutes - 13.9 MBBryan lays down some motor speed facts in about 10 minutes in this short podcast episode. We can figure out how quickly a single-phase motor (PSC) will run if we understand how many cycles it will make per second. In the USA, the standard hertz is 60 Hz (60 rotations or magnetic alternations per second). Motors are inductive loads that create an electromagnetic field with a spinning rotor and stationary stator; the amount of poles on the stator determines how quickly the rotor spins (RPM)....
Value Design in High Performance Home HVAC w/ Comfort Squad
May 05, 2022 11:00 - 53 minutes - 73.8 MBNeil Comparetto and John Semmelhack of the Comfort Squad join Bryan to discuss high-quality value design in a high-performance home. They explain how they design HVAC systems (heat pumps) for low-load homes in ways that are affordable, efficient, and comfortable. High-performance, low-load homes need to be energy-efficient AND comfortable, and it can be a challenge to get both. Manual J calculations aren’t as common as they probably should be, and it can be difficult to get accurate data a...
Putting Contractor Success First w/ METUS
April 28, 2022 11:00 - 36 minutes - 50.7 MBLacey Dietz with METUS and Scott Arnold with Rycor HVAC join the podcast to talk about how the industry can start putting contractor success first. They talk about Mitsubishi Electric (METUS)’s commitment to contractor success and what that looks like. METUS’s contractor program aims to provide training, support, and recognition to create a community of successful contractors. Support comes in the form of marketing, training, tech support, and customer service, and those services are avail...
Retrotec - IBS 2022
April 26, 2022 11:00 - 8 minutes - 12.1 MBSam Myers with Retrotec talks to Bryan about pressures in the home and why they matter for HVAC solutions at IBS 2022. Technicians focus a lot on ductwork and airflow, but many of them don’t focus on how the building envelope impacts HVAC performance. A lot of the HVAC equipment’s performance is affected by the push and pull of air caused by leaky areas in the building envelope. If you have a room with too much air and another room with too little, you will have unbalanced pressures. Unb...
Birmingham training class
April 21, 2022 11:00 - 2 hours - 224 MBThis podcast is a class that Bryan taught for BTrained in Birmingham, AL. He covers troubleshooting, installation, and commissioning best practices with a focus on the fundamentals. To be a good troubleshooter, you must be able to find the problem, identify the source of the problem, fix the problem, and optimize performance based on your data, the customer’s comments, and your observations. The Five Pillars of diagnosis aren’t comprehensive diagnostic or charging criteria, but they can he...
Ross Trethewey IBS 2022 - Short #141
April 19, 2022 11:00 - 15 minutes - 21.3 MBBryan has a bit of an industry nerd out with Ross Trethewey from “This Old House” and TE2 Engineering at IBS 2022 (the International Builders’ Show). Ross’s education and career have focused on mechanical engineering, especially with sustainable solutions. In building science, the key mindset is to think of the building as a system. Using that school of thought, Ross has developed building science and HVAC solutions that also consider indoor air quality and ventilation, such as hybrid VRF ...
Replacing a Compressor - Step by Step
April 14, 2022 11:00 - 39 minutes - 54.7 MBIn this podcast, Bryan goes through the entire process of replacing a compressor step-by-step. This process is what the Kalos team uses to replace a failed compressor and make sure it doesn’t fail again. Before replacing a compressor, you must figure out how the compressor failed; grounded conditions often lead to acid, so it’s a good idea to test for acid and see if you need to address a burnout. In any case, make sure you have the correct tools for the job (including a compatible replace...
Refrigerant Top off, Drop in and Retrofit - Short #140
April 12, 2022 11:00 - 8 minutes - 11.9 MBIn this short podcast, Bryan explains what it means to top off, drop in, and retrofit refrigerants. He describes the differences between those three things to dispel some of the confusion they may cause. Topping off a system means that you add refrigerant to a low existing charge to get it back up to a normal level. In some cases, people top off systems with dissimilar refrigerants (e.g., topping off R-22 systems with cheaper R-407C). Topping off a system with a dissimilar refrigerant is u...
The Value of Networking for Techs w/ Trevor
April 07, 2022 11:00 - 29 minutes - 41.2 MBTrevor Matthews, the founder of Refrigeration Mentor, is back on the podcast. This time, he and Bryan talk about the value of networking for HVAC techs as the conference season comes to a close. Many trade events are networking opportunities that allow you to build relationships with other tradespeople, educators, mentors, and even other companies. You can also learn many trade and business tools that help you as a technician. Many technical and business conversations occur at trade events...
How to EFFECTIVELY implement educational growth w/ David Richardson
March 24, 2022 12:00 - 34 minutes - 48 MBDavid Richardson of NCI joins the HVAC School podcast to talk about how we can implement educational growth effectively throughout the trade. NCI started as a premium training resource about airflow testing, but the organization eventually started teaching about combustion testing as well. When we improve the industry, we need to be able to have concrete ways to see what we’ve been doing wrong or what we can do better. Test instruments allow us to see the whats and whys behind what we do. ...
Comfort Investigation on TV w/ Corbett Lunsford
March 20, 2022 11:00 - 18 minutes - 25.2 MBCorbett Lunsford of Home Diagnosis joins Kaleb to record a podcast about comfort investigation on TV.
