I'm not convinced that's true. The problem with mini splits is the lack of air purification and having to maintain each head. In my opinion new systems like Rheia make a lot more sense. Still ducted but has a simpler install. Bonus is it has a high air mixture for comfort which traditional HVAC and mini splits don't offer.

Hi Linda! We have the same last name!

I think the mini-splits are the bomb but I also think they can be improved upon. No 1# is they would be better off with a sealed 134A bldc motor compressor with a stand-alone embedded controller that will run off a min of 72vdc so that it's easily able to run off a bank of six 12vdc 100Adeep cycle marine lead acids (which can be obtained new for only about $100 each). My current project is dual 134A compressor system running off such a bank (approx 3 ton) and I think just a 1000 Watt bldc controller can use an alternator re-purposed as a bldc motor to push a single 134A compressor (a Valeo) @ about 500 Watts no problem. (I'm currently using a PM DC but it only takes 12 amps @ 72vdc to drive both) I upgraded caps to 100v in four ubiquitous mpt 7210As and each pair of 300 watt Q-cells (about $65 each) series-ed together puts out 72vdc un-loaded which (coincidently enough) is what the charge controllers are designed to charge at. Their outputs can be paralleled too. Getting around the need for costly un-reliable up-converters for turning DC to AC is a big plus too. BLDC condenser and evap fans are as well, though I'm pretty sure most split units already come with one or the other. The systems I use (for bus vehicles) came with barrier hoses with O-ring fittings that only require band clamps engaged with a tool like pliers to apply. People need to take solar away from the government and all these opportunist contractors (that just want people to finance a costly installation) and get with the program. AC is the lions share of everybody's electric bill. Solar is nothing but using enough panels with charge controllers to charge batteries and keep them topped off as you run whatever you power off of them. Keep them charged and they will last just like in a vehicle. That's the key.

There are mini splits made that work from Grid as well as DIRECT from solar so more efficient since no conversion of the Solar to AC power when solar power available and can use a smaller inverter usually.

Thanks for the very well explained presentation... All that I have seen with the ductless system, so far, have been retrofits; but I am yet to see a clean installation for a new project. Bearing that in mind, the mounting walls always seem to be exterior-walls-preferred. In new construction, mounting on an interior partition could offer more flexibility; so my question is: Is a 3" PVC pipe located in a 3-5/8" stud wall sufficient to run all those lines from each a/c head? or can each of those lines just freely run in the walls uncovered by your slim duct? And lastly: If then running those lines under a slab-on-grade, what diameter PVC chase would you recommend as a minimum? I suppose that with proper planning the condensate drain line could follow is own path, or even drain to indoor plumbing.

Hey Troy, thanks for watching. I am the opposite of you as I have basically no experience with new construction projects. All of the jobs I have designed have been new projects like this one, so unfortunately I don't have those answers for you.

This is a really good video. I'm currently restoring a 4200 ft2, mid 1800's home and I've dumpstered the entire HVAC system. The 1600 ft2 upstairs is 4 BR and 2 baths and will be used as a B&B. The rest of the time, it will sit empty, so I wanted to design it with a mini-split to give the occupants full control over their comfort. Well... that led me to wanting to do the same with the 2600 ft2 downstairs where I'll live. I'm looking at Daikin, Mitsubishi, and LG. What scares me is that I can't calculate my power consumption for a typical South Carolinia summer. How does a full, zoned mini-split system (with as many as 11 units) compare with a traditional duct heat pump system, assuming a very efficient condenser? I've seen your videos where the homeowner was installing solar collectors so can I assume it's gonna be low?

How are the units working

Paul, Do you have a comment on using a mini split in about a 2400 square foot walkout basement that comprises a great room, game room that are adjacent, and then also two separate bedrooms with doors? Should I use one head in the open area and expect it to AC the whole area, or recommend using a separate head in each bedroom and game room and great room. Generally speaking the basement never feels warm in the summer because the upper level is fully centrally air conditioned, but it can get stuffy. I'm told that basements generally are well insulated and don't require as much cooling and heating if they are sealed up real well and don't have much air leakage. thanks.

For many minis, the compressor can only run as low as 1/3 of the unit. For a 36k unit, if you're running one head, the compressor is still kicking out at least 12k BTU. If you're only running one head that only needs 9k, the system will short cycle because it's over running itself.

@@rykin ok thanks . I am aware that each head can only run so slow but there is also a much greater surface area of condenser per BTU with say one head running at 5,000 BTU than 3 running at 5,000 BTU so heat exchange with atmosphere should be more efficient . My impression is that even with regular split units with inverter compressors they are more efficient per BTU at lower BTU outputs. such as a 2 ton unit producing 12,000 BTU at their lower range versus at the sane unit at 16,000 BTU output even though the compressor is still matched to the output BTU the 12,000 is more efficient Generally.

You can them from amazon or any HVac website. I noticed one thing that my mr cool cover discolored so quickly! It is not even a year old and I can see the cover changes from bright white to dull white with yellow hint to it. The alternative way is to buy water down spout from any hardware store. Split it open and put on your line set. I found they look more attractive and durable at least they don’t discolor quickly like mini split covers do .

It depends on everyone's situation. With this homeowner having solar panels as well it will be a lot quicker because their gas and electric bill will be close to $0. Without the panels you're still looking at an electric payment and probably a fuel bill for when it gets super cold. the range depending on the situation could be 5-15 years.

The outdoor condenser is a heat pump, so it provides both heating and cooling.

What about venting and make up air? The reality is there is no return air like a regular forced air HVAC system and there is no fresh air make up correct ? Regular furnaces usually have a flue system to exhaust the return air. Doesn’t this system need fresh make up air and return air to be exhausted ? Am I missing something here ?

@paultheplumber8665

There is no ducting so the air runs right through lines that feed directly into the indoor units. It's also a heat pump so the heat is generated from the condenser. Does not connect to any furnace.

Old system in the house did not have central air (you see floor heaters in the vid) so nothing changes, open the windows for makeup air, my experience with houses here in US vs in EU is they are all super drafty/leaky, when it is windy, i can feel cold air entering, in EU with brick houses and XPS insulation on the wall and plastic windows it is pretty airtight, and those newer houses need makeup air badly (increased humidity that creates mold issue) but to keep efficiency high you have to use air to air exchanger in order to keep heat losses under check www.controlledair.net/blog/2013/september/why-an-air-exchanger-is-a-good-choice-for-your-h/

I'd imagine a serious energy audit with spray foam air-sealing in every nook-and cranny would need to be done as well as a ton of air-sealing and fiber cellulose in the attic. If they have a serious commute that clipper-creek EVSE will suck up most of those electrons coming from the roof anyway.

20k to 30k on average for this model. It's a "hyper heat" model that is going to increase the cost by a minimum of 5k. Normally if you have an honest crew. You could do something like this for 14k to 18k. But that's assuming you get a normal minisplit system and the install crew is willing to do it for cheap.
