Ductless A/C questions
I am having some trouble finding answers to basic questions about installing a ductless a/c unit, so I was wondering if any of you had info. My questions are: – For one large room (approx 550sq ft, 40 x 15 or so), would a single zone mini-split do the job? – What is typically (roughly)…
I am having some trouble finding answers to basic questions about installing a ductless a/c unit, so I was wondering if any of you had info. My questions are:
– For one large room (approx 550sq ft, 40 x 15 or so), would a single zone mini-split do the job?
– What is typically (roughly) charged by an installer to install a single zone, roughly 18000 BTU ductless unit? This would be for the 3rd floor of a building.
– This is for a rental (long term rental) and when we leave, we will need to repair the wall. Roughly what would the cost be of doing this? It is an external wall (obviously) of a pre-war building.
Thank you all- that’s all I really needed to know. I’ll abandon this idea. Thanks!
I looked into doing this as well.
Firstly, the ductless unit has two parts – the part that spits out the cold air (inside your house) and the part that spits out the hot air (outside your house). Is there a place to put the part that spits out the hot air? We are on the 5th floor of a 12 storey building – it was too far to put the hot air unit on the ground or on the roof, and there was no ledge for it to sit on. It really cannot be attached to the side of the building – it is seriously heavy.
Due to our situation, we didn’t look into it further, so I am not sure if a ductless system requires the creation of a large hole in the wall. For instance, we need a large hole for wall-through airconditioners. This is a pain, because then you will need planning permission. This means getting an architect and an expediter, which could be greater than the cost of the system + installation.
Ah, you sure you want to be doing this? First off, this is for a rental apartment? Is your landlord OK with it? In answer to your questions, yes, an 18,000 BTU ac unit will be more than enough to cool your whole apartment/floor through. How well it works will depend on where the inside unit is located and the layout. Installation of the unit ALONE (i.e. without electrical) will probably run you about $1500 assuming its a very straightforward job. Electrical could trip your project up, however. You will need 220 Volts for any Mr. Slim over 12,000 BTU, which runs on 115. Even for the 12K BTU, which I think would be big enough anyway, your circuit breakers may not be large enough – i.e. you may need some extensive electrical upgrades to accommodate a ductless AC unit. Furthermore, have you given thought to how the interior unit will be drained? Ours goes back outside, but I assume it could be linked to an interior drain.
Why don’t you call some A/C experts to have them come and do an estimate for you. They do it for free.
I highly recommend Mike Weston at Weston Brothers in Queens. They did our split systems (Mr. Slims) for our first two floors and were just wonderful to deal with. He has also done the work for several of my neighbors and other friends through the city (and everyone loves using him). Actually we had four or five different mitsubishi installers come thru and ended up with Michael.
Below is his information. Sure he would come out and give you the whole scoop. Very professional.
