I would have watched the entire install if recorded. Like a 8 part mini series. Next level work bro.

Great Quality work Zach! Keep it up🤝. Glad to see you have helpers too.

Amazing job Zac. Top quality work, craftsmanship, and tools. Love to see it.

Started my apprenticeship and grateful for your videos

Nice installation. I work for Fujitsu and appreciate your videos. Good job!

Hvac tech here in chicago. Your installs are next level. Love the videos. Great work!

Nice upgrade! I would be real happy being the owner of that setup. Clean, practical and efficient. Rarely have I seen a zone damper system work well. The communicating systems are the only ones that seem to work only if the design is absolutely perfect. Still inefficient at low loads though.👍🏼

Great craftsmanship and great filming - super appreciated this video. Thanks!

Here in FL the inspector would never pass that install without securing the outside units to the pad. Yea, we have hurricanes. :) Too bad there was no way to bring the line set down through the walls vs along the side of the house. We put in one of those Gree Flexx systems to replace a Carrier builder spec single stage unit for our second floor that just never seemed to hold the temp. (Brand new house, after 5 years hating it, and too many repairs (needed new coil once I was done) The gree works great. I was concerned but 2 years in now 0 problems. Having a non-communicating but fully variable system is excellent. I think more manufacturers should do it that way. I think Bosh is like that too.

Nice install, the customer will be comfortable for their first time since living there. I’ve installed zoned systems that worked perfectly, but the labor and materials always made the one up and one down systems better for everyone.

That install looks good af! Great work!

Thanks for taking the time to make this.

That adapter for the NAVAC vacuum is brilliant. Def thinking of getting that vacuum now.

You're an inspiration for someone wanting to start their own company

Great work Zach. Very effecient work too.

Very nice clean change out. Good work

You do some very clean work. Love the video’s.

Nice and clean keep the vids coming!

Lots of good tips in the vid! always best to prime wood before painting. Wouldn’t recommend plywood for a cover. A steel plate, with hasps, or another type of lock would be more secure, and last a lifetime.

I’ve used a 5 gallon bucket with holes drilled into it and then filled with gravel but that 4” corrugated perforated pipe is a good idea. Been installing for years like seeing tradesmen who take pride in their work.

Dude, so glade you made this video! I was wondering a way to seal the hole if I went from a gas pack to split furnace.

I really like how you always make your systems Neat and Prim.... a landscape canvass if you will.... I have a very old rural home with a 4 ton Rheem HVAC, the duct work is for crap, but to rework this house, would exceed my SSA check in a hurry... oh, it uses Natural Gas for heat.... that is cost efficient at least.

We love the Gree flexx system we just started installing them a few months back here in North East Texas

That’s a nice set up for the drain tubing, tstat wire and high voltage

What a clean looking job. Very nice! Can you do a video on how you run your duct system coming off the air handler? 11:17

Good video ! One Upstairs unit & one downstairs unit is Allways a Great way to go as Far as Comfort & energy savings goes as upstairs sometimes might not even be occupied. Only thing I don’t like about this system is that the Air handler for the 1st floor is sitting on the Dirt & After the First Rain ☔️ Floods under the House that units going to be Full of Mold in 3-6 months. a Better Solution Would have been to put the Air Handler in the House in a Closet & Make the unit a Down Flow Airhandler putting a plenum box under the closet & attach ducts keeping everything out of the Water & Dirt under the house. Bonus: Air handler is more easily serviced also. Good video ! & it’s better than it was before comfort wise but Health wise the ducts were out of the dirt & Rain water under the house. I HATE PUTTING UNITS UNDER A HOUSE ! They ALLWAYS GET FULL OF MOLD ! Your a Smart Guy , Try to Find a Better Solution , if possible. I Would Go back to this Job and Dig out under that unit 6” & Put it on Bricks & iso pads or use Hanger strap to secure it to the Joists under the house putting an iso pad between the joists & unit for sound isolation. Fill the 6” Hole under the Unit with Rocks for drainage. That Should Keep the Water out of that unit, Give that unit a chance at Survival in the Rains & the Occupants “ Mold Free “ Air.

Nice neat job. Blessings to you.

Very clean.

Always love your work mate 🙌🏼 The duct tape for band aid get extra points

Another nice and neat job.

Nice install! Are you sure the indoor coil is precharged with 410a or is it nitrogen? I install a lot of these here in Canada (Tosot brand, which is Greer). next time you do one of these, crack the indoor coil service valves, you’ll find that it’s nitrogen in there. At least it always has been for me. Wanted to let you know as that might screw you a bit if you were to have a huge nitrogen bubble in your heatpump system.

clean install man

Milwaukee just released a battery powered vacuum 5cfm. Been using for a week, works well. might wanna grab you one. Nice work

Fantastic upgrade! Very clean work. Only thing I don't understand is why didn't you keep the downstairs on a package unit? Having the air handler under the house just seems like a lot of work

@OcRefrig

10 ай бұрын

Who knows, but most likely it was a 5 ton package ( since it was serving the whole house ) & Having 5 tons just serving the downstairs would probably be unacceptable - 2,000 Cfm for just the downstairs is going to be noisy supply grills, unit short cycling, more expensive electrical bills. Who knows , but these are just some of the reasons it would not work.

Clean work 👍🏾✅

nice gree unit bro👍

Love the heat pumps. I was kind boggled at the solution you pulled out - I hope it was very old, and not done int he last few years. That WAS a horrible HVAC design. You must live in a climate with no snow. That "door" would never pass muster anywhere there is snow. Even if that's marine grade plywood, those edges need more sealing that that in a northern climate. I'm impressed that you did the cement work and sealed the building yourself. A rare level of service, these days.

@ 19:29 amen brother! Preach! People install zone systems all wrong.

Does the GREE FLEXX have a rear knock-out for that 3/4 and 3/8 copper. Or did you have to make a modification? I'd think there would be some rubbing against the condensing unit.

So I’ve installed a few Gree flexx units, no problems yet, what’s your opinion of them Zach?

That's what I need. I have 2 single stage systems and the upstairs is never comfortable. When I upgrade I will add a similar system. Don't know if I should use a variable system or a two stage system.

@tschuuuls486

Variable is just better.

If you can lock out strip heaters at 5 degrees F, where does the condensing unit gets its heat for defrosting exterior coils? When l lock out strip heat, my domestic unit drops the interior temperature by 3 degrees during a defrost, which it struggles to catch up to before the next defrost cycle comes. The ODW is not happy with that blast of 55 degree air either. For that matter, how do mini splits defrost. They never have strip heat, yet I never felt them blow cold in the heating season?

do those condensers come with pre installed filter driers ?

Where did you get the battery adapter for the m18s?

Have you thought about the Amana S Series equipment?

That dog looks exactly like mine including the bob tail.

you said "full variable speed system" Are those air handlers variable? I have the Mr Cool (Gree) 4-5 ton system and the air handler isn't really what I would consider "variable speed"

I am sure that house has a staircase that connects both floors. I think the units are not going to work 50% each, i.e., one unit cooling the second floor and the other the first floor, as it is intended. Cool air goes down and warm air goes up, through the staircase.

I wish there was someone in North Texas like you that I could trust to do a professional job. The guys that did my new house were morons and I have had to either fix or replace most of what they did. I still have a leak that I cannot find on one of my systems.

Maybe the Asians do not make unitary systems? That three ton heat pump condenser looks a heck of a lot more complex than a domestic unit. I presume that is how they reach their efficiency levels.

Why did the old unit have TWO existing disconnects? Did you hook up the 240 from air handler and 240 from condenser on same disconnect? Or just just used the same path to get to the breaker panel?

@kamrenkong

10 ай бұрын

Units with 2 disconnects will have a separate disconnect for the electrical heat kit to break up the load from the heatpump .

What units did you Install I couldn't understand what or if you named it in the video I'd like to install one of those in my house. Ohhh Gree! I thought green 😂 thanks great work 👍

Unfortunately that system is still essentially a 1 speed where the thermostat is on/off. They are variable components that run off a regular thermostat removing their variable capacity. I never understood why they do that, but at least it’s a small step in the right direction.

Are you guys allowed to run romex outside in TN?

Its China state owned brand. Plus may not has replacement parts available few years later.

Just had a question. First off I'm not an hvac guy and not judging just curious. I assume all that the previous 2nd floor ductwork left a cavity the the lines etc for the new unit could have ran in. Was it not used because of the extra lines etc distance or drainage?

I've actually run into this exact same system design down here in Chattanooga. I wanted to rip it out or not even touch it but you know how it is when you're working for someone else...

What is the link to the Milwaukee adapter

I stopped trusting HVAC and I just do it all my self for my self including having gotten my EPA license. Its hard to find people like you so I gave up and gave in and just learned all this stuff my self. Just installed my own Pioneer 2 ton mini split - properly - I have all the necessary tools and I use only Fieldpiece and Yellowjacket mostly just like the pros. I have 3 more r22 ACs on my home that are about to die any month or year now. I am going to replace them all with inverter based split systems and do it all my self. I can't afford $40,000 to replace all my units when I can do all of it myself for like 10k. Sure I give up some extra warranty period but I can do all the work so warranty is good for only parts anyway for someone like me.

Not a super fan of linesets laying on the pad but it looks great.

Where did the drain terminate for the crawl space AH

Putting air handler in crawl space seems like it would be harder to service. Check float, make any adjustments to blower fan. I have the rebadged version of these units in mr cool. I'm not an hvac guy but have engineering background. My A coil came with a leak and I found it with a leak detector so now every 6 months to a year I check my units for leaks. Would be a PITA if it was in crawl space. Seems you probably had little or no other options here. Another hvac guy says to put micron gauge up at air handler. In my case I just went with precharged lineset. Curious how well those crimps will hold up over time too. Also curious if you put in filter dryers?

At 5 degrees, would it not be inefficient for it to run in heat pump mode due to the lack of ambient heat? Seems like it wouldn't hurt to have the electric heater kicking in at a higher temp, but systems have come a long way.

@tschuuuls486

10 ай бұрын

Nope. Modern inverter heat pumps still archive ~180% efficiency/1.8 C.O.P just above the minimal operating temperature. Some of them have reduced capacity in the -4°F/-20°C temp ranges, but that's it. Most american heat pump brands just ignored all innovation beyond the 1980s and shipped the same product because it's cheap ;) There are heatpumps that can operate down to -22°f/-30°C.
