Usually the install is what irtis not much choice since it has to function first .In apartments often the wiring is complicated so ask what is possible

I believe PTACs run on 220, and certainly an all-electric heat pump one (no gas) would. Running a 220 line isn't usually "complicated", it just needs to be done.

A PTAC is a "packaged terminal air conditioner"; it's a through-the-wall unit (a glorified window air conditioner.) I'm guessing that you are considering a mini-split heat pump and not a PTAC.

PTACs are like what are found in hotel rooms. As OP used the term, I assumed that was involved but maybe it is minisplits. I question if minisplits would be possible in an NYC high rise.

220 electric is sometimes the huge issue in old buildings Since this being done in all the units ask the installer where it will function best . I will be honest never have used this type of heating .

I've been in rooms with a PTAC. They made a racket because everything (compressor, fan, etc.) was inside the unit.

White Noise. That's why hotels use them.

" White Noise. That's why hotels use them. "

I don't think that's it. Rather, I think it's done because it's an inexpensive way (both construction-wise and equipment-wise) to give each room individual control to choose heating or AC and a range of temperatures.

In response to Patricia I have been given the choice of anywhere on the wall behind the sofa so that’s the design question-where to place it along that wall (unless it’s not clear it will be next to the ceiling-so the question is where along the wall from the corner on out)

A racket is right! They keep me from sleeping well when I'm in a hotel, they are so dang loud.

EJ I got that information about white noise from a mfgr's brochure but after hearing your observation I'm inclined to think you are correct and dismiss the brochure as marketing hype targeting naive buyers. May I ask you and our collective group for help in understanding what's gone on starting with original post?

Verbatim, this is original post.

"Our heating unit needs to be replaced in our condo (NYC high rise) and in our building everyone’s going to PTAC units. The furniture in the picture will be replaced at some point but I’m trying to decide if the PTA unit should go in the corner or more centered on the wall. It’s not a large room so the placement will only minimally impact the heat distribution. "

Is there a question mark anywhere in original post? ( The post is nothing more than idle musings about buying new heater and furniture)

Since no one here claims to be a mind reader or sorcerer, what gave rise to discussions about electric power? ( Modern units are more energy efficient so it's a safe bet power serving old unit will be more than sufficient for modern replacement)

I could go on but I do believe re-reading thread will show how convoluted the discussion is from start to end.

Not long ago I was sitting behind two people, once before a funeral began and once during break at a hog calling event. Both times I overheard those people having a laugh about people at online forums. The jest being to make a passing comment with no foundation then watch as people run 10 directions without reason. One likened it to watching a bunch of monkeys trying to hump the same football. I coined the phrase and used it since to describe the puzzling behavior.

Anyone notice op has been silent despite people grasping at straws?

It might help if you spent more time reading and less time blathering because op (me) had not ‘gone silent’ (scroll up). Also, as long as we’re reminiscing, your post reminded me of a boss I had when I was just starting out who said “Draft legislation as if you’re teaching fourth graders because that’s the level most people understand.” So my apologies, Klem, that I did not use a question mark; I thought it was obvious that I was seeking design advice when I said
“I’m trying to decide…” I stand corrected.

Most PTAC units in older hotels are, indeed extremely noisy. If current units are the same, you wouldn't want one in your home! However, like most other things, they've probably improved immensely over the last 20-30 years. So if you're thinking of going this way, I'd ask your installer to give you a couple of recent references so you can evaluate them yourself.

Having said that, if your condo permits the use of mini-splits, I'd definitely go that way.

" if your condo permits the use of mini-splits, I'd definitely go that way. "

I was dissuaded from thinking that might be on the table to consider when I noticed the reference to a "NYC high rise". I suspect the presence of any one of the following by itself- line set length and height difference limitations, a building's limited available roof space to mount multiple condenser units, and the presence or absence of usable vertical channels to run the pipes to lower floors, would make mini-splits not feasible.

Elmer is correct that we aren’t able to split anything. The installer is doing a whole bunch of owner units so hopefully we’re not gonna all be miserable with a lot of noise. Thanks to everyone who responded.
