With all the rebates for heat pumps over the past few years, these units are getting installed at an alarming rate. Seeing this teaching video for a refresher or for up-and-coming techs to learn is great. As always, Jim, great video.

[@grashoprsmith]

great, informative video

Looking good Jim

That return looks really close to what I’m assuming is a supply. Please correct me if I’m wrong.

[@measureQuick]

It is, however, remember the supply register will throw the air clear across the room without recirculating into that return. That system actually works exceedingly well for air circulation, and particulate removal.

Can you use measure quick on vrv systems ?

[@timrob0420]

Jim how do you like the Bosch systems? I’ve been liking the IDS 1.0 a lot because it has a Mitsubishi compressor

[@measureQuick]

I’m a fan. I have one in my house and have one at the office. It’s super quiet in the cooling mode and super efficient. Heating wise it’s a little bit noisier, but it does a great job. Heating the house all the way down to 15°.

True tech tools due better. 😂
