Product Description

Fujitsu ASU12RLS3 / AOU12RLS3H Halcyon XLTH Wall Heat Pump Air Conditioner 29.3 SEER - 12,000 BTU (1 Ton)

The Fujitsu 12RLS3H ductless mini-split system is a heating and cooling unit. This unit comes with a wireless programmable remote control (optional wall mounted wired controller available) as a standard feature. This unit is pre-charged with the environment friendly R-410a refrigerant. No additional refrigerant is needed if the line set is 49 feet in length or shorter. Also, the 12RLS3H is all new and comes with many new innovative and energy efficient features like ESP (Energy Saving Program), Programmable Controller and Inverter technology!

In order to comply with manufacturer's trademark agreement please note that the product images are very close to the actual product but they may NOT be actual images of the product you may receive. Please send us an e-mail or open the product brochure to view an actual product image.

- Halcyon system knows how to save you money even when you forget. If you leave the room without turning the unit off, ESP knows that you left and 20 minutes later, set temperature is increased by 4ºF when cooling and reduced by 8ºF when heating. When you come back to the room, it returns to previous operating mode. This prevents wasteful operation to save energy without you having to think about it.

- Weekly timer can be easily set by wireless remote controller. ON, OFF can be set up to 4 times in one day and up to 28 times in one week. For other modes, program timer and sleep timer can also be selected by pushing a single button.

- Heating capacity at low outdoor temperatures was improved by adopting a large heat exchanger and a high capacity compressor. Rated heating capacity is maintained up to 20ºF. This new model can operate down to -15ºF.

The All New 9RLS3H, 12RLS3H and 15RLS3H units feature base freeze prevention. It prevents the condensate at the outside unit from freezing with its build in base heater and drain holes. This cultivated base design discharges melted water through  many holes. Without a heater, freezing condensate can cause noise, damage to fan blade, condenser, and system performance.

  • Wireless Programmable Remote Control
  • Apple Catechin Filter and Ion Deodorizing Filter
  • Sleep Timer

Why Choose a Fujitsu Halcyon Inverter Unit?

The Solution is Clear 

  • Cool only the areas you want and not the areas where you are not
  • Individual zoning at the push of a button, putting you in total comfort control 
  • Less then 5% cooling loss occurs in insulated refrigerant lines versus up to 40% through ducts 
  • Requiring just a 3 to 4" diameter hole in the outside wall means less mess, better home aesthetics, and improved security, unlike a window unit 
  • Halcyon models mount high on the wall so they don't disturb your view 
  • Fujitsu units add value to your home and are more efficient than old window units, saving you money

Customer Reviews

Great Unit, but we did need some extra help for install Review by Scott B
We have had this unit installed at my son's house in Utah for about 8 months. It provides AC and heating in an apartment (250 sq ft) located in the garage. I really love the technology, and options for adding comfort to multiple rooms without sheet metal duct work.

I did have to increase the amperage out to the garage, and hire an AC guy to get the AC kicked off. Other than that it has been maintenance free and holding up to extreme weather.

From now on I am going this route for AC and heat. The traditional way is passe. Can't go wrong here. (Posted on 3/12/12)
Superb system. Review by Mohamed Muhpad
We have installed this system in our small restaurant and it works perfect. The entry door is being opened and closed all day long and this system helps to keep an even temperature in the store. We will never go back to the window ac system again. (Posted on 7/20/10)
Great system Review by enrique garcia
A wonderful piece of equipment, easy to install, quiet, efficient, works great.
I recommend it highly. Thanks for good salesmanship, delivery and compliance with advertised results. (Posted on 6/24/10)
Very pleased Review by Michael Boyd
very quiet and provides a lot of cooling capacity for such a small system. It cut my electric bill in my office by 60%! Fast shipping from green droplet was also good. Get one and you won't regret it. (Posted on 6/22/10)
Great air conditioner. Review by Chris Faulkerson
great system. I'm surprised how powerful it really is. We will be buying another one for our office in the next 2 weeks. Great customer service from folks at green droplet made us very comfortable to do business with. Will be back soon. (Posted on 6/12/10)
Easy to install. Very quiet. Review by Linda Kosky
The 12RLS is a great air conditioner. I live in Arizona and our living room needed the extra cooling because of our high cathedral ceilings. One of the sales people recommended the 12RLS and it is working like a charm. Thank you much! (Posted on 6/1/10)
Powerful machine Review by Timothy Kolacky
Unit is smaller than I thought. I was a little worried that the outdoor compressor is going to be noisy but it turns out that I almost can't hear a thing in the back yard. I am happy with how the system heats/cools up my living space. Very fast and even. Great unit, great quality. (Posted on 5/17/10)
Love this! Review by Anthony Montie
this is a very powerful machine. I needed extra cooling and heating in my sun room and this one delivers. I like it that it heats with low outside temperature and
it is very quiet. I am very happy with my purchase. Green droplet has
these in stock and ships next day. This was my second purchase from them.. (Posted on 5/14/10)
Very pleased with the purchase Review by Kate Miller
I have done an extensive research of what is the best 1 ton mini split system and I decided to go with the Fujitsu 12RLS. I am very happy with the unit. I love the quiet mode which makes the unit go silent while still cooling. We used it in our theater room and it works quiet and effectively. We also got the wall mounted thermostat and now we can control the system from the wall and not have to worry about loosing the remote. Over all a great system and it qualifies for the federal tax credit. (Posted on 5/12/10)
Not bad Review by Jeff Heart
Unit was just installed and it is running great. It is very powerful, it cools my 450 sq ft bedroom very fast. It is also very quiet. The system came in 3 days after I placed the order and I will be getting another unit for my other property soon. (Posted on 5/11/10)
