No Ductwork No Problem. Ramsond Ductless (Duct-Free) Mini Split Air Conditioning Systems can be installed in virtually any location. Ductless Mini Split Air Conditioners are also referred to as Zone Systems. They cool/heat the zone or areas in which they are installed. When the zone is in use, the mini split system can be turned on. When the zone is not in use, you can simply turn it off. This zone capability allows for substantial energy savings. Ramsond Heat Pump systems not only provide cooling during the hot summer months, but also provide efficient heating for the winter. They are far more efficient and substantially more economical compared to conventional central air conditioning systems. Ductless Mini Split systems are comprised of two main components: 1) The outdoor unit (Condensing Unit), and 2) The indoor unit (Evaporator Unit). The installation is simple. The indoor unit hangs on a metal bracket (supplied) that attaches to the interior wall, much like a picture frame. A three inch (3) hole is then drilled through the wall. The Line set and communication wires are passed through this hole and connect the indoor and outdoor unit together. The Main power is supplied to the outdoor unit. The indoor unit draws its power from the outdoor unit. The system is operated by a wireless remote control (supplied). Simply set the remote control to the desired temperature and the system maintains the desired temperature.

So far i have tried it in both modes. Heat is great and also does keep the area comfortable when in cooling mode. Best feature is the dehumidification mode. Unit is quiet and efficient. Area in question is over 800 sq ft.
Pros: Lots of Features, Easy to Install, Looks Great, Good Size & Weight, comes with a line set, installation a breeze
Cons: remote display on hand unit is small, air handler wall mount could be sturdier

Review 2 for 12,500 BTU 1+ Ton Ductless Mini Split Air Conditioner & Heat Pump - 220V/60Hz
This unit is very quiet and is cooling my living room and kitchen very nicely. The instructions need to be more detailed especially the electrical hookup. Found a good 24 photo step website that cleared up my electrical issue. strongly recommend hiring AC guy to vacuum system not expensive saves damage to compressor Will buy a unit next year for bedrooms.
Pros: Easy to Use, Easy to Install, Good Size & Weight
Cons: instructions more detail

Review 3 for 12,500 BTU 1+ Ton Ductless Mini Split Air Conditioner & Heat Pump - 220V/60Hz
I installed this product in an efficiency apartment on my property to replace a window a/c and a ductless propane wall heater. Installation was easy... installed it myself in about 6 hours (I'm a retired contractor) and felt very comfortable that I had the perfect solution to my heat and air needs. It worked perfectly for about 2 months. Used both heat and air initially (installed in May of last year), then started using a/c only in June. About 2 months after the installation, I came home one day and noticed water had been dripping from the unit for quite some time. The floor and a nightstand below the unit were soaked from water dripping from the bottom of the unit! Checked the drain hose outside...no water coming out. I blew into the hose and felt resistance and water immediately began flowing again. Called tech support & got pretty much a run-around. The problem has persisted ever since. My solution has been to use a wet vac on the drain hose every time it starts dripping water inside the apt. which seems to correct the problem for a month or two. It only happens when I'm using the a/c since the condensation doesn't occur when in the heat mode, so I've resigned myself to the fact that I'll have to continue the wet vac solution every few weeks during the hot months. Seems like gunk accumulates in the drain pan and clogs the drain even though I religiously clean the filters every month. In other words, Ramsond needs to re-engineer the drain pan and either put a small pump to keep it cleaned out or make the pan and drain hole big enough to eliminate any debris that might accumulate there. Other than this ongoing maintenance problem, the unit seems to work very well... just be sure to install the indoor unit someplace where you can put a bucket underneath it while using it for a/c and invest in a wet vac to suck out the debris when it starts to leak.

Review 4 for 12,500 BTU 1+ Ton Ductless Mini Split Air Conditioner & Heat Pump - 220V/60Hz
Once installed, the unit ran quietly and effectively cooled the 450 sq ft space... but getting there was a challenge for the 2 engineers at every step in the 10-12 hr process.
The instructions were poorly translated to English and required "reverse engineering" to figure out the intent of the designer. The bleeding instructions were ambiguous in spots and vague or incomplete in others. Something as simple as, "Once the two lines are connected, remove the access covers and using a hex wrench, completely open the valves. (A hissing sound would indicate the connection is not tight enough). Remove the remaining access cover on the lower valve to reveal the schrader valve. Pressing that valve for 1-2 seconds allows the trapped air to escape. About that time, cool refrigerant will escape, thereby signalling the trapped air is purged out of system. Replacing the access covers completes the process." would be clearer.
Some annoying details: Inside mounting bracket on 16.5" centers; outside pedestal (bracket spacing) is 20". A 50 mm (2") hole is tight. The lengths of the copper lines coming out of the inside unit should have been made longer so as not to constrict the necessary tight bend coming out of the wall.
In most cases, the 25' long line is too long and there is no way of coiling it out of sight and have it look neat. To reduce the length requires a flaring tool. (the US tool for 1/4" and 3/8" slipped a bit when flaring metric lines). Some mention about reducing the lengths would have been nice.
No provision for attaching a shielded Romex (primary power) to unit. Instead a weather proof extension cord-like arrangement is used that requires a special clamp at the disconnect box.
The plastic covers for the electrical and refrigerant connections are ill-fitting, fragile, and may not offer much protection in snow or heavy rain. (one of mine was cracked out of box.)
In summary, I think the unit was rushed to the US market. More time could have been spent on instructions. I judge the primary power connection means to the unit to be marginal at best.
Like I said in the beginning, once the unit was installed it seemed to do a respectable job of cooling the room. The unit was installed in a cabin which gets intermittent use. How it fares over long term is TBD. I will keep my fingers crossed.

Review 5 for 12,500 BTU 1+ Ton Ductless Mini Split Air Conditioner & Heat Pump - 220V/60Hz
Once installed the unit woks great however the instalation insructions are a unclear, at best. You will need a profesional HVAC contractor to vacume out the lineset before you start up the unit, unless you have a lineset vacume in your garage.
Pros: Performs Well, Light Weight

Review 7 for 12,500 BTU 1+ Ton Ductless Mini Split Air Conditioner & Heat Pump - 220V/60Hz
I bought this heat pump and had it installed by a professional. Since day one it was nothing but problems, mainly the controller was causing the issues... at least that is what their tech support said. Finally got fed up and bought a new one (Fujitsu) from a local hvac company and it is working great.
