Ductless mini split air-conditioners are relatively new to North America. However, they are the most commonly used system of air conditioning throughout the rest of the world. Ductless systems are also referred to as 'zone systems.' Understandably, ductless split air conditioning systems are becoming more popular in homes and offices, even when they are equipped with advanced central air conditioning system. By providing zone cooling, Ramsond ductless split system air conditioners save energy, since only the rooms that are occupied and used need to be cooled/heated. Simply stated, they cool/heat the 'zone' or the area in which they are installed. They require no expensive ductwork installation. This is the reason that they are far more efficient than conventional air conditioners. You can turn on the system when you want to use the area/zone and when not in use, the system can be simply turned off, saving electricity and money. Operating costs are much lower than those of central systems that cool every room, whether or not the room is in use. So, with a ductless system you can control the temperature of a zone where it is located. Therefore, you have the benefit of cooling only the room that you want, while leaving the central AC system off.

Ductless mini split system air conditioners combine the zoning flexibility of a conventional room unit (a single air-conditioner installed through a wall or a window frame) with the whole-house cooling potential of central systems. Like central systems, they have two main components: a compressor/condenser (outdoor unit), as well as an air handling unit (indoor unit/evaporator), which contains an evaporator and a fan. All Ramsond models are also equipped with heat pump, providing both summer cooling and winter heating.

There are two parts to a ductless systems. The indoor unit (evaporator) and the outdoor unit (condenser). The indoor unit is installed on the interior of an exterior facing wall. The installation is extremely simple. The indoor unit is equipped with a mounting bracket. This mounting bracket is secured to the wall and the indoor unit clips onto it; much like hanging a picture frame. The outdoor unit is typically placed on a flat surface outside. The indoor and the outdoor units are connected by a series of wires for power and communication. Once the indoor and outdoor units are connected, then the connecting pipes (Line Set) need to be attached between the indoor and the outdoor unit. There are 2 sets of connecting pipes; the 'suction line' and the 'liquid line.' These insulated connecting pipes are pre-flanged and need to be attached to the connections of the indoor and the outdoor unit.

Unmatched Quality and Components
R410A-SEER 14

Ramsond Ductless Mini Split Systems are simply the best systems presently in the market. The cutting edge quality of Ramsond ductless systems is simply unmatched. Quality is never compromised at Ramsond. Only the best quality and first-rate components, such as rotary type compressors, and activated carbon filters are used in Ramsond products. All Ramsond ductless split air conditioners are pre-charged with certified R410A refrigerant. The R410A refrigerant is far more efficient than the typical R410A that is used in most air conditioning systems. It enables the high efficiency of the unit while preserving the ozone layer. This is another testament to Ramsond's dedication to environmentally friendly products.



Integrated Advanced Air Filtration and Heat Exchange System

All Ramsond ductless systems are equipped with two (2) anti-mold dust/particle filters, along with two (2) Activated carbon filter cartridges. They are installed under the front panel cover of indoor unit. These filters are easily washable. They ensure a constant circulation of fresh, healthy and dust free air. Additionally, the blue colored hydrophilic aluminum foil in indoor unit are designed to stay free of water contamination, enhancing heat exchange efficiency and air quality.


Super Silent Operation and Sleep Mode Function

Ramsond ductless mini split air conditioners are among the quietest (both indoor and outdoor unit) in the market. The indoor unit has a virtual silent operation. So silent that some of the world's most renowned recording studios utilize Ramsond ductless systems in their sound-rooms. Also, equipped with SLEEP MODE function, with the touch of a button, your Ramsond mini split system is set to automatically adjust the room temperature during your sleep.


Microprocessor Controlled Smart Operation

Ramsond ductless split air conditioners are equipped with highly advanced, state of the art, microprocessor controlled climate control system. Through this system, the environmental comfort is perfectly adjusted to your desired settings. The quality, flow and temperature is constantly monitored by the internal computer system of the unit to ensure optimal performance and maximum efficiency.


Dimensional Oscillating Swinging Louvre Air Delivery Technology

Multidimensional oscillating louvers of Ramsond ductless systems ensure the uniform flow of air throughout the room. By selecting the 'SWING' feature on the wireless remote control, the louvers will continuously move in a uniform up/down movement to evenly spread the cool/hot air. They same feature would allow the louvers to be set in a stationary, single direction position which will focus the flow of air to a particular area of the room.


Superior Inner-Grooved Copper Tubing

The copper tubing of Ramsond ductless systems are grooved on the interior. This enables a much faster refrigerant flow, increasing the heat exchange coefficient and efficiency by 30-50% over the traditional smooth copper tubing.

Product Reviews

  1. Great Product 4 Star Review

    Posted by on 9th Sep 2016

    Easy to install if you have common sense, instructions could be better, overall the product is good and works perfectly

  2. Remote 3 Star Review

    Posted by on 16th Nov 2015

    I have figured out how to use it! The owner of the apartment told me not to move the thermostat and I was not sure why, but I discovered that it won't work unless it is being pointed at the unit. I still am not sure what the blank buttons are for, but hopefully I will be warm.

  3. Remote VERY Unclear 2 Star Review

    Posted by on 16th Nov 2015

    I recently moved into an apartment with this system and I cannot find anywhere how to use the remote. I changed the temperature on the remote, but it did not change on the system. The online manual has no information on to use the remote or what the unmarked buttons mean. I am cold and frustrated. If anyone could enlighten me on how this darn thing works that'd be great.

  4. Quality design and easy install 5 Star Review

    Posted by on 7th Jun 2015

    Installed myself and the unit works great in cool and heat modes! Very much worth the price!
    Runs so quiet that you can hardly hear the outside unit and or the inside unit. Just totally satisfied with the product and would suggest to anyone to purchase this product!

  5. High Quality Product/Easy to Install 5 Star Review

    Posted by on 30th May 2015

    PRO'S-Very well made product, easy to self install, great customer service! I installed this unit entirely by myself and I am very proud and happy with the results! The unit operates just as it is advertised to, and cools so well I have to watch how cold it gets and the heat pump side heats so well I have to watch how hot it gets! PERFECT!!! The inside unit is so quiet you hardly notice it running and the outside unit is just as quiet.
    CON'S-I only have a few suggestions for the company to try to improve on Shipping-the first unit came damaged and I had to send it back for a replacement. Installation manual-really need to be a little more specific in certain areas of the installation instructions and drawings!
    Overall it has been a great product and would repurchase again!

  6. Does not cycle 3 Star Review

    Posted by on 29th May 2015

    The unit cools great, but it does not cycle on and off like a normal unit.
    The outside unit cycles on and off but the inside unit stays on (fan always blows)it has to be turned off by the remote. Would have been nice if the Whole unit would cycle on and off like a normal central air unit.

  7. Nice add on to our new room 4 Star Review

    Posted by on 10th Oct 2014

    cools room well, haven't had to use the heat yet so that's the only reason it didn't get a 5 star rating. if the heat works as well we will be buying another one for the other part of the home

  8. Great Product - Love it 5 Star Review

    Posted by on 30th May 2014

    I installed this unit a little over a year ago and I love it. It is quite, cools the 17 x 18' room in less than 5 minutes. It saves me on my electric bill. My bills in the winter time and summer have gone from well over $250.00 a month to around 130.00 a month. Couldn't be happier. Thanks for the product.
