Ductless home AC

[Torinoman]

Anyone know what this is all about? I hear it advertised on the ticket and looked at the website but can't tell what the "benfit" is.

The units look like the kind of wall unit AC at a motel but they also have multi room setups. Does it just run the Freon to an individual fan setup in each room?

Doesn't seem worth it for the amount of equipment you'd have to buy unless the equipment super cheap?

It's easier to install in homes that do not have / need central air.. I think that is one of the biggest markets for these. Don't have to run duct work and all of that. Most people I have heard using them down here is for shops and garages, especially detached.

They are intended more-so as an add-on option, or for a place where you are looking for a more simple install, like an older home that has limited access. There is still a separate outside condenser unit that connects pretty simply with one set of wires and 2 copper lines to an inside package evap unit. They even make some that will connect the single condenser to 2-3 inside evap units if you are doing multiple rooms or a larger space.

My brother did an add-on at his house, where he built a home studio for his business...it's around 800sqft. He used one of these units out there and it has worked out really well for him. He did the install himself, in about half a day, and his even came pre-charged with refrigerant. I looked at this option for my shop, but a good friend who is an AC guy talked me out of it in favor of a traditional split system, since my space is so open, and even though insulated well, it's still a metal building.

Each air handler bolts to your wall on the inside, runs its high/low lines to its own compressor condenser outside.

Great for shops etc

Lower costs on the system itself. We considered it for our farm house (no central hvac), but went window units instead. Finding a competent installer in BumFuckNowhere, OK wasn't something I wanted to deal with.

They are expensive to install the split systems due to line runs, but still less costly than central HVAC, I believe.

I have only seen one setup, so i am no expert. This was an older historic home turned into a museum. It was basically a commercial chilled water solution. The system used an outside heat ex-changer and ran a loop (pex line with glycol) thru the basement to each unit. The system was a slick install for this application.

Advantages I see: No ducts, great for older homes, each room has its own thermostat.
Disadvantages: More fans, more thermostats, more moving parts to break.

So what do these things cost? I have an older home where the AC doesn't cool the bedrooms well but the rest of the house is fine. Rather than re-engineer the whole thing a dedicated system for just the bedrooms might be nice.

Do they also heat or just cool?

If it is good enough for bob sturm, it is good enough for me!

Just get a window unit sized for the room.

Damn. That's not bad at all. Maybe we should have done more research. Spent more than that on the window units, and a split would have definitely been a more appealing visually. I also didn't see any that I could install myself. Most I looked at seemed extremely complicated.

That is for an a/c for one room though. Unless you use floor fans and keep doors open, it isn't going to cool from one room to the other. I use this one in my garage.

As I pointed out above, you can run multiple inside units off of a single outside unit...depending on the size of the condenser you can run up to 4 evap units. Some examples here....

Exactly!

RoomS, plural. 3 total to be specific. But 1500 doesn't seem bad depending on what size space it can cool

Any idea what a 3 room setup might cost?

It works good for a single large room situation. I bought a older house and almost went this way for the ac up stairs. My issue was there were five room upstairs counting the bath and no way was it cheaper with splits including heat pump. I ended up spending around $4k on a tradition split system HVAC for the upstairs, down stairs is a package unit. 2.5 ton up stairs and 4 ton down. I'm planning on using one for a master bed room addition.

I found a 36K BTU 2-room setup (with heat pump) for $2400...you can figure about $300 for a third evap unit, so I'd say about $2700, maybe a little more. That's out the door price though, I was going to install mine myself.
