We created a YouTube channel for just you! HVAC mechanical engineers face quite a challenge today. Systems must be designed with high reliability, small footprints, low power consumption, low acoustics and vibration, efficient heat transfer, and high filtration – and do all this within the end users’ budget. Whether you’re a mechanical engineer, mechanical contractor, or building owner, you’ll learn about how to meet those challenges from our HVAC application and design videos.

In this live recording of episode 29, we will discuss the new DOE minimum energy-efficiency standards for single-phase residential air conditioners and heat pumps known as expressed in the new terms EER2, SEER2, and HSPF2.


Some Of Our Greatest Hits!

In this video, we discuss the difference between a Copeland Digital Scroll Compressor and a Danfoss Variable Speed Compressor. These two HVAC modulating scroll compressor technologies accomplish similar results but are constructed differently.

In this broadcast, we show the difference between Relative Humidity and Dew Point using graphical examples and psychrometrics.

In this video, we share three common mistakes regarding equipment sizing and grow room HVAC equipment selection: missing the required dehumidification load, not understanding the room sensible heat ratio, and selecting off-the-shelf air conditioning equipment vs. commercial grow room air conditions, aka grow room dehumidifiers.

In this webinar, we discuss Basic Psychrometrics 101.

We look at properties of air, building the psychrometric chart, psychrometric processes, and finish with examples of determining air properties.

In this Psychrometrics Part 2 presentation, we discuss air mixing, sensible heat ratio (SHR), calculating air quantity, determining tons, and full load vs. part load.

In this LIVE PDH-qualified event, we were joined by Mark W. Fly, PE with AAON, Inc. We discussed different fan types and their characteristics, fan curves and fan laws, how to use and apply them, fan stall and unstable regions of operation, and how to select the best fan for the flow, static, and acoustical performance desired.

In this LIVE one-hour PDH event, Insight Partners CEO Mark Murray and Tony Mormino were joined by three special guests from Nortek Air Solutions, the world's most extensive custom air handling unit manufacturer and creator of the popular Fanwall Technology. This back-and-forth, interview-style presentation uncovered five common myths associated with fan arrays.

In this LIVE PDH-qualified event, I was joined by custom air handling unit expert Mark Brady with Nortek Air Solutions. In this presentation, Mark shares the best techniques for controlling fan arrays. We discuss the optimal number of VFDs, types of controls, and motor overload protection. 

In this LIVE event, I was joined by HVAC water filtration expert David Romeo with Miller-Leaman. We discuss RO Filtration, Thompson Strainers, Turbo disc, and sand filters. David shares the pros and cons of each technology and how it can be applied to your HVAC application. 

In this LIVE PDH-qualified event, I was joined by Tony Furst with Armstrong Fluid Technologies. If you are looking for masterclass on pump and system curves then this video is for you. 

In this LIVE one-hour PDH event, Insight Partners is joined by leading cooling tower expert Mark Pfeifer with Marley, SPX Cooling Technologies.

The learning objectives of the presentation are as follows: Help you choose the right cooling tower for your customer’s needs. Avoid common mistakes in the cooling tower design procedure.

In this live podcast, we quickly look at the six most common types of heat pumps used in the HVAC industry today. Heat pumps are gaining popularity as an alternative to traditional gas heating systems as the world moves towards electrification and away from fossil fuels.

During this podcast, we discuss the skilled trades in the HVAC industry and why there is a shortage of all trades, especially HVAC technicians. The demand for HVAC services has increased significantly in recent years, and the HVAC industry faces a skilled labor shortage.

In this episode we interview Greg Crumpton, VP of Service Logic, the largest privately held Energy and HVAC/Mechanical Services company in the United States.

Join us for an exciting live recording of Podcast Episode 39, titled "HVAC MythBusters Event: Separating Today’s Fact From Fiction." Our panel of experts will debunk five prevalent myths in the HVAC industry.

Myth #1: A2L Refrigerants Are Highly Flammable and Dangerous. Myth #2: College Is the Only Path to Success. Myth #3: RH Is an Accurate Way to Measure Humidity. Myth #4: My Digital Compressor Is Short Cycling! Myth #5: Hot Gas Reheat Dehumidifies the Air.
