Installing a 3 ZONE Ductless HVAC System

We're back at the 3 zone ductless install and it's time to finish up this project. With the help of all the quality products by DiversiTech, this job turned out real nice in my opinion. Just like having the right tools, having the right materials is crucial for a quality ductless installation.

After 45 years doing hvac and now retired 6 years I still enjoy watching others working. Many new tools and products make a job so much easier. I thoroughly enjoy your professionalism and pride you take in your work. Great job, wish others I watch on-line would follow your example.

Nice work! We always cut out the flares on wall mounts to ensure no leaks and also mighty brackets help a bunch with wall mount installation. It also helps if the copper lines have about 6 inches of play left to right behind wall for ease of install I learned the hard way myself it’s not fun. Your videos help me out so much thanks

[@selders591]

As a HVAC/R tech with over 20 years in the business I enjoy watching your videos. On this install on your wall penetration I have found a trick I used a few times. Now this depends on how much space you have in the speedy chase. You can take a 4” or 6” schedule 40 pvc elbow and cut it in half and install it inside your penetration. This will give you a nice smooth 90 degree transition so your lineset and insulation doesn’t get screwed up. Just a fyi.

[@USA-GreedyMenOfNoIntegrity]

[@Cosas95]

Awesome job, neat and clean. I'm a home owner and I installed my system with a helper, decided to cut the lines at the indoor unit and solder, a friend made the connection at the condenser, he said I did an excellent job.

[@Mitch2294]

I cut the lines and brazed several one less place to have a leak but had a indoor head with a leaking coil they declined the warranty because I cut the factory flares off.

[@zacharyloewke6366]

I quit reaming my flares with the pen style reamers. I found they can scratch the inside of the copper which will eventually become the surface of the flare connection itself. I use the cone style reamer for those now after having one leak on me. Nice work, boys.

[@rodgraff1782]

If you file the end of the pipe flush with a jig, you can totally eliminate the burr. File flush used to be a stage of preparing the pipe for flaring. I don’t know if it’s taught anymore.

Great job Zack and Trevor, You definitely do quality work, I give you that, and the pro press on the line set was good idea.

I have a Lennox mini vrf heat pump, 4-ton with a single zone vertical fan coil. It is amazingly efficient, quiet and far more comfortable than a single stage system. It rarely ever runs past low speed on the indoor unit.

[@joshuaseaton4526]

Any new construction jobs I do, which are very rare, I always tell the homeowner/contractor that I need a 12" wide pathway in the drywall below the unit to cut and braze those lines in the wall. I absolutely will not have flares or press fittings concealed.....ever!! I bet if you politely mention it to them on your next one they will gladly do it for you. No big deal to come back and do a small drywall patch afterwards and it makes all the difference... cheers!!!!

[@HERITAGEWV]

Food for thought.. there is a correct way to use a adjustable wrench “crescent wrench” The force/pressure should always be pushed against the solid jaw of the wrench, not against the lower adjustable jaw. So.. I was just watching and wondering if that would have any effect on calibration or accuracy with the torque wrench you were using on those flare nuts 🤔

[@jrsmyth9761]

Maybe I misunderstood your process on the vacuum. On the multi port units I deal with, the vacuum can be done from the ports on the main set of valves, the top ones where you release the refrigerant, through all your connected ports. The service valves at each set of lines are simply for service after the unit is in service or to close off the unused ports. While it is not incorrect to do it the way you stated, I would read the manual and confirm, pulling through the top/main ports should be less time because you can do them all at once. Also, it is possible that the lines from the main ports to each set of valves may NOT be in a vacuum from the factory. Again, your unit may be different than the ones I work on. You could add the 10oz after you pull a vacuum, but BEFORE you open the valves. With unit in a vacuum it will easily pull in extra charge.

[@shifter8207]

Seems like a mighty bracket ductless split tool would have been great for you to do all your connections behind that Evap

[@Mike-01234]

I want to put one of these in get rid of my ducted system. I have a flat roof home replacing the duct work along with a new split system would cost lot more then running lines and air handlers. I could use the old duct work to run the line set then put the highwall over the old vent.

[@vehache_fly]

Hello Zack!!! First of all, greet you and congratulate you for the valuable channel you have on YT and thank you for all the information and advice you give us in each video. I would like to ask you, since I think it could be valuable for many of us outside the U.S., like me who is seeing you from Chile, to know what the pricing policy is for professional HVAC technical services in Tennessee, from a simple service like changing a condenser or replace a thermostat, to other more complex ones such as the installation of equipment such as mini Split. This with the idea of ​​making a parallelism or comparison between the U.S. and the rest of the countries in the HVAC business and that we give the proper and fair value to our work that we do with professionalism and care. In my personal opinion, it would be very valuable to see a video of you talking about the rates for HVAC services in the U.S. Thank you very much and may God bless you and your whole family. VEHACHE

this is a disadvantage of the box that you laid in the wall, if the tubes were sticking out of the wall, then you could just connect. And so very good work, I like your approach to work. keep it up !

[@EricJohnson-dr5wb]

I’m guessing that you are supposed to have plenty of slack in your lineset and your control line. Then you can pull out what you need. And don’t fix the lineset and control cable to the box.

My name is Ash from the United Kingdom and I like your video very much. The reason I like your video you've made it so simple. When I was in Apprentice if it was that simple I would have to struggled all my life. But now I am they're doing the air conditioning long time back now bring lots of other things now. If you can do a video on heat pump systems that be great heat source heat pump but I would like to call it. As a refrigeration Guy all I think is just reverse valve but I don't know. I'm thinking of installing this myself in my own property in the United Kingdom. But many thanks the wave explained is wonderful articulate
