Summary
Join us for this eye-opening session from the 7th Annual HVAC/R Training Symposium featuring industry experts Roman Baugh, Jon Esquivel, and Adam Mufich as they expose the truth about inverter-driven HVAC systems.
What You'll Learn:
- Common Inverter Problems - Why these systems fail and how to prevent callbacks
- Design Mistakes - Oversized inverters acting as expensive single-stage units
- Dehumidification Challenges - Understanding sensible heat factors and humidity control modes
- Building Science Integration - How envelope leakage and infiltration affect inverter performance
- Installation Best Practices - Proper setup, commissioning, and field settings configuration
- Troubleshooting Techniques - Using the diagnostic triangle and understanding EEV operation
- Refrigerant Charging - Advanced methods for verifying proper charge in inverter systems
- Climate-Specific Applications - When inverters thrive vs. when they struggle
Key Topics Covered:
- Why education is the biggest challenge with inverter technology
- The difference between "smart" and "dumb" inverters
- Dehumidification modes: overcooling vs. coil saturation control
- How duct leakage creates a "double whammy" effect
- Rotary vs. scroll compressor technology in inverters
- Mini-split performance data and missing specifications
- Variable capacity adjustments and compressor overclocking
- ERV integration and ventilation strategies
- The importance of building envelope testing

| 0:00.0 | Yo dog. This is the HVAC school podcast. This is another live episode from the symposium, our training event that we did down in O'Couye, Florida this year. And this episode is with Roman Baugh, VRF, VRV, aficionado, and KALO's team member, |
| 0:23.8 | Adam Mofich from NCI, |
| 0:24.9 | and John Escovel. |
| 0:28.6 | John is a long-time contractor, |
| 0:31.4 | building science expert and friend of HVAC school. |
| 0:33.2 | And they are going to talk about, |
| 0:34.7 | do inverters suck? |
| 0:37.1 | But before we hear about that, |
| 0:38.9 | we're going to hear from our great sponsors. |
| 0:41.7 | Carrier and Carrier.com. |
| 0:44.7 | Carrier has been a long-term sponsor of the podcast. |
| 0:50.8 | They've made it possible very early on for us to do what we do, and they are the products that we sell day in and day out, everything from single stage equipment all the way up to the green speed |
| 0:54.8 | extreme, one of the most efficient products on the market today. Find out more about what |
| 1:00.5 | carrier has to offer and about becoming a carrier dealer by going to carrier.com. |
| 1:06.6 | Refrigeration technologies and their Viper pan and drain treatment. |
| 1:16.0 | Viper pan and drain treatment is a spray gel that you can put in your drain pan in the bottom rows of the evaporator coil. It utilizes enzyme-based cleaning, which works on tough sludge, |
| 1:23.3 | biofilm, and works wonders on our climate here in Florida unique challenges like bacterial |
| 1:29.6 | zuglia, otherwise known as elephant's not. It's also non-toxic and food safe. It's been shown to |
| 1:35.5 | outlast traditional drain tabs and lubricates the drain assembly to keep those drains clear. Who doesn't |
| 1:41.8 | want a lubricated drain assembly? Am I right? |
| 1:51.0 | Find out more about the pan and drain treatment from Viper at refreegeTech.com. |
| 1:57.3 | Navak and Navakglobal.com and the break-free power flaring tool. |
