Our annual trip to Milwaukee PIPELINE is always great fun. This year we talked all things Packout with product manager Nick Trawicki. 

Packout was first released in June of 2017. Since its launch, Packout has expanded to literally hundreds of products that are mostly intended to save us time on and off the job site.

Calling all apprentices (and those training them)! 

One of our most listened to episodes went live back in April 2024 and still tallies downloads today so we decided it was time for a followup! 

We changed it up a little from our first list of 5 Things Apprentices Should Do Every Day 

Thanks for listening, have a great day!

This episode aired in August '24 and had been one of our most downloaded ever, give it a listen, we hope you enjoy it. We will be back with new episodes soon! 

Ever think "If only I knew then what I know now" ?

We are so pumped to bring you this and the next episode with special Guests Heather Aune & Sheryl Mickelson, the obvious better halves of the MTGA team. 

Sheryl runs the office and a good part of the business for Mickelson Plumbing & Heating. 

Heather has done the books for both MH & Aune Plumbing & Heating for over a decade on top of her (former) day job. 

It was so cool to hear their perspectives as we consider looking back to the early days of starting our business.

Andy and Eric discuss their recent project installing a Viessmann air-to-water heat pump system, exploring its performance, efficiency, and potential applications in radiant cooling and heating. They share insights on system design, energy savings, and practical considerations for HVAC professionals.
Takeaways

• The Viessmann system can operate quietly and efficiently in residential settings.
• Proper piping size and layout are critical for system performance.
• Monitoring power consumption helps optimize system operation.
• Wide delta T in radiant cooling shrinks as the system reaches steady state.
• Condensation risk can be managed by controlling dew point and set points.
