Great content, would love to see more videos on minisplits

[miguelquiroz]

You are the one of the greatest Instructor for the HVAC Industry. thank you so much. Keep it up. I got your book by the way.

[Clint]

More ductless videos! They are becoming more popular we need all the help we can get

[resurgensix]

Thanks Mig! I passed my EPA UNIVERSAL on the first try with your help!

[guitarhvac]

Love it. Would like to see more on the inverter drive and troubleshooting mini splits.

[hassanbangs]

Great job am really educated on your project

[blh]

Great job! I really like the easy access on the lower wall unit for installation and cleaning. I wish all the wall hung ceiling cassettes were this easy...

[andrewflewelling]

Very helpful. Thank you! Particularly on the low wall units and on the ceiling/wall units.

Hey Craig in the future will you go over checking charge on minis, diagnostics on controls and maybe city multi ?

[sprockkets]

Also since C&H is just a Midea clone I rather buy direct from Pioneer or Senville. Senville has upped their prices but I like how they made the electrical cover on the outdoor unit - you can take it off since the part that holds the conduits is stationary and not part of the cover as it is on C&H and Pioneer.

[tomjones]

Would love to see a video discussing max line set lengths.

[ROYALPRIX]

Keep in mind if you're adding additional zones, most places tell you that you can, as long as what is currently running is more than 50% of the refrigerant.

[nicholusedwards]

Thank you for that piece of important information, continue teach us.

[familyhvacheatingandaircon]

Nice video
I would like some troubleshooting charging and all that good stuff wiring zones, signs of to look for on a call
Haven't really worked on this units much.
Keep up the great videos

It would be nice to see a similar video in the future, but focusing more on the various types of mini-split outdoor units: single-split and multi-split (both shown here) on the one hand, and VRF/VRV on the other hand, and the implications regarding piping and electrical/communication line differences. Small two-piped VRF/VRV systems (e.g., Mitsubishi Electric City Multi) could be very interesting when (e.g., gas-based) heating systems covering only one floor of an apartment house are to be replaced by air-to-air heat pumps/split ACs. The VRF/VRV outdoor unit can be practically placed anywhere in the garden, comes with just two pipes and a signal cable, and the indoor units can be connected in parallel mode by using Y-connectors as each of them comes with its internal EEV. Very interesting are branch box controllers which allow the connection of typical (cheaper and more feature-rich) multi-split indoor units to a VRF/VRV outdoor unit. Very great channel, by the way! Thanks for all of these videos!

Hey Craig. Thanks for another great video. Could you also explain how to properly install and seal minisplit linesets? There is notorious leaky minisplit lineset issue, when linsets develop formicary corrosion within 2 years.

[meyerjeff]

Never miss the opportunity to insist that all flaired line set connections MUST BE torqued per manufactures specification.

[Josh-injh]

Thanks for the awesome content. Love the chapters you’ve added

[jamainebrown]

Great content 👍🏾 I love installing ceiling cassettes Mitsubishi electric 🇯🇵

[toneblair]

I love all your content. I want to dog into the airflow side of things a little more.

Can you make some videos on how to size ducts?

Thanks for all your hard work!
