I was surprized at fist with your choice of heat pump heating. But considering that avagege low winter temperature is around +3 degrees C in your area, this is a good decision. The avagege low winter temperature in central Russia, for examle, is -10C. Here this kind of heating system will be too expencieve even electricity costs less here, than in US.

[@lanceo1690]

If you want to get heat to a lot of individual rooms wall units (wall warts) are the more costly option. We just bit a job where we looked at quite a few combinations of spiders and wall warts. In the end we found that two spiders (air handlers and ducts) were most efficient and cost effective. Great episode though. Will likely recommend our the clients watch it :)

I'd get some runners down on that new carpet good video thanks

[@2ddw]

Completely agree with these ductless systems, especially for A/C. Who wants to pay to cool the whole house when you only want to cool the master bedroom so you can sleep at night? With an upstairs master bedroom and a central HVAC system, the fan has to work extra hard to push heavier cold air up and it just spills out the floor vent, under the door and down the stairs leaving the top half of the bedroom still hotter than you want.

[@stevenslater2669]

Humidity control is as important as temperature control. In high humidity areas of the country, the A/C must run long enough to remove the humidity. If you oversize the system you will pull temperature quickly, but the system will cycle off before the humidity can be removed, leaving you with a cool, clammy home. Back in the '50s thru early '80s my dad had a small commercial refrigeration and A/C service company. We had a commercial customer who insisted we set up his new home with an oversized A/C system. My dad tried to convince him it was a mistake. After a couple of seasons we downsized his system to what we had calculated originally. An expensive lesson.

[@bnasty267]

@@stevenslater2669 Another, and better, option for humid areas is a separate whole-house dehumidifier tied into the ductwork. Then, you can hit target humidity levels exactly and not have to overcool the house to drop the humidity. In many humid areas, there are days in the Spring/Fall that still have high humidity, but aren't really hot enough to justify running the AC enough to dehumidify. If the air is being dehumidified, you can probably also set the AC temp higher and have the same comfort for less cost.

[@richardmckrell4899]

18` SER is average at best for a mini split system. With dedicated exterior units for each inside head you can get up to 32 SER (that's 77% more efficient cooling). As soon as you do multiple interior heads for an exterior unit, the SER decreases substantially.

[@WoLpH]

Do you have any information about the R values of the walls, windows and other parts? Efficient heating/cooling is important, but not having to heat/cool is better :)

[@robertkovacic4623]

Everything you said about low consumption, efficiency, etc. perfectly true, but under one condition - the units (external and internal) must be maintained! By that I don’t mean anything special - just cleaning and disinfecting ... but just doing it right!!! - not just a little spray and it’s over. The evaporator slats need to be cleaned, if necessary-dissmount and clean the fan (check the fan's slide-bearing grease),clean the front and rear tub (most service technicians do not clean the rear because it is very difficult to access), air deflectors, etc ... Most people don't do that, and they forget to maintain the device ...the service technicians usually work as little as possible and charge as if they did everything necessary🤨👎 It's a lot of work, it's not cheap, and that's why I do it myself with my four devices ... once a year😅 I like your videos - keep it up😃👍 Greatings from Slovenija.

[@kevindavison6019]

I feel like heat pumps have a place, but that's not in a custom home. Hanging a big plastic control unit on the wall just looks ugly. You might say the same thing about Hydronic baseboard but that is generally lower and doesn't distract from the finishes and trim on the walls. I feel as though heat pumps at least in my area (Maine U.S.A.) have gained popularity due to a large rebate program in the last couple of years. However just recently there has been an 80% increase in the electric rate so that cuts into the wallet quite a bit if you commit to using electricity for heating and cooling. I personally have baseboard and underfloor radiant heating using a wood pellet boiler with a propane fireplace and a woodstove. They all have their pro's and cons but I chose to install it all for specific reasons, and it works well for me for a really reasonable cost.

[@webstermckinney6893]

Biggest problem with mini split is that the line sets tend to me colder and sweat more than conventional split system. This is not as big of a deal until they are run inside wall cavity and create moisture problems and potentially mold growth. I say this because I work at a property with 140 units with mini splits and have had this happen on multiple occasions. Also a side not is they are less efficient at removing moisture from air if that matters in your climate. But they are very energy efficient

[@williambryant5946]

Where's the channel going to go after the house is done? Will there be another house build? That's why most people are subscribed is to see houses being built so hope there is another build in the near future. I've been thinking about replacing my heat pump with a mini split system in the house and installing one in a building I have that is dedicated to a model railroad. Its finished just like a house and the only thing missing is water and HVAC system. I've talked with people that have them in new houses like you've done here. A couple of the people I've talked with had previous homes. One with a heat pump and the other with an oil furnace and both are very pleased with the mini split systems as is the other person that is in his first home. So I've thinking seriously about replacing my HVAC heat pump system with a mini split system. I'm in central NC so it doesn't get extremely cold but summer time can be brutal with the humidity factored with the heat. My electric bill is always higher in summer so I hope the mini splits will help lower my cooling cost and the only thing I'm concerned about when considering a switch to them is can they cool as efficiently as or hopefully better than the system I have now.

[@Estok8805]

I am no expert, but my first thought when reading this is that the condensate from the mini-split head unit needs to go somewhere (you need to connect it to a drain somewhere). If you're still planning on adding water to your model rail building then that's easy to do at the same time, otherwise you need to think of some alternative like installing a drain line to the outside or something.

The head units only need to run a small fan, the power is run in the lineset from the outdoor unit. The outdoor unit has the compressor and has the big amp draw. We had a 36k BTU system (4 zone) installed last summer and it was 30 amp total.

[@FirstnameLastname007]

I think if it's over 18kbtu it's usually 240 . 15 - 40 amps 120-240 volts I think

[@MandoFettOG]

I have a 27k three head unit that is 240v 35 amp at the condenser. The head until are powered through the power panel on the condenser. Just easier that way so that the head units can communicate with the condenser and if you're already running a wire might as well be power too.

[@martinparmer]

@@MandoFettOG Yeah, I knew the big power draw would be the outside unit, 240v but was just thinking how neat it would be just to have to run a 12/2 or 10/2 w/g to the room unit if it was only 120v 30 amp or less. These things are the future of home AC IMHO. Thanks!

Mini splits are wonderful pieces of technology. They are everywhere in historic Europe used in retrofit applications. However, I can't help but feel they are a lower quality option in new construction. They may be efficient but the wall mounted units are unsightly. A ducted system seems a lot more "correct" to me. If given the choice. I would prefer not to have those units on the wall. Again, in retrofit or additions their pros outweigh cons, but this brand new house with minisplits would be a negative to me.

[@mattv5281]

I had a similar system put in this year, and I agree. I love the ducted air handler, but I kind of hate the mini splits. They are unsightly, they don't circulate air as well, and they are kind of noisy for a bedroom. They whir and click and rattle. In my case it would have been a few thousand more for a ducted air handler that serves the bedrooms, compared to two mini splits. At the time the cost of the whole system was a stretch, but now I regret not opting for ducted everywhere.
