We have a ductless Mitsubishi split in our Florida trailer home which we will soon be leaving for seven months. Anything we should know about leaving it behind? We are not planning on leaving it running as it is our first year of using it and we aren’t sure of potential problems we might have while we are up north. Thanks for an advice

I will say that if you dont have some type of air conditioning or dehumidification you run the risk of returning to a house with mold. Set the thing to 82, have a maintenance performed by a qualified technician, and possibly hire a house watch or have family check the place periodically.

If I was you I would pull the power disconnect to the condensing unit. You may also want to cover the condenser only to keep dogs or cats from urinating on the unit. If there is no possable way that will happen no need to cover it. When you come back in7 monts make sure the breaker is off to unit and wash condensing coil with high pressure from garden hose.

SOURCE: how to pump down a ductless air conditioner split unit to remove

if the unit contains R12 or R22 you are not permitted by law to do the work yoiurself .. you have to have a "certified" person to reclaim the freon ... you might be able to get away with removing R134A (check local law) if thats what it has ... there is a service port that you can hook gages/hoses/vacuum pump up to .. (if not, then one must be added, usually in the form of a saddle valve that penetrates a low side feed pipe ... you should vent it into an approved tank or bladder (like a big balloon) for disposal or reclamation .. there may be a community service in your area that comes out and reclaims freon from old refrigerators and such .. in my area there is a free service that will reclaim the refrigerant and take away the old equipment .. i think its free or low cost .. some people simply vent R134 to atmosphere but that is polluting and may violate some laws .. R134 was thought to pose little hazzard but that is being reconsidered now in many countries

you can become certified yourself by attending a class and taking an exam that shows you understand the dangers and are aware of the law ..

SOURCE: Freezer begun tripping our 20 amp breaker for some reason

ok hi there i viewed the specs for this freezer
http://www.truemfg.com/catalog/servlet/com.apsiva.servlet.HomeServlet
this unit must be plugged into a 120v outlet with a 15amp circuit breaker dedicated (nothing else should on this circuit) so all by itself. you have to check the voltage outlet where you plug in. you must have at least 115v or better (125v the most) if you have less then 115v it will cause damage. ok you went and checked all this out and everything is 15amp with 115v or better and it still trips breaker.
ok the running amps is 6.8 amps so to blow the circuit you need 15 amp which is too high.
i suggest you call a refrigeration guy because he will be able to determine if the problem is the compressor (which has a 4 year warranty with truemfg.com only in the USA) or something else. Usually but not 100% what would make a freezer like yours to blow the fuse is the compressor. if it overheats it will do this, if there is a sudden high pressure within the system it will do it, if you have a condenser fan that is not running at proper speed it will do this...
the problem cannot be pin pointed understand please... you have to babysit it, watch for changes in the refrigeration system and the running compressor amps, voltage drops ( this will cause high amps) etc...
Refrigeration is not easy and alot of tech stay away... so those who stick it out make money cause you have 2 choices: buy another one and pay big bucks to get it fixed. at least see if you can find someone to come over (for like $40 - $60) and tell you exactly whats wrong with it... whew... hope this was helpful and not confusing...sorry

Is this a 1or 2stage compressor

I don't know specifically..but just about anything with a 16 seer is going to have a two speed compressor combined with a variable speed blower in the furnace. Some utilize 'inverter technology' and utilize a variable speed compressor to deliver ultra- high ratings. Though available for residential use, they show up mainly in systems used in commercial applications. Daiken, Sanyo, Mitsubishi to name a few...and are usually ductless split systems.

I guess this answer really is of no help.....

Ductless Split Air Conditioner Review

Ductless split air conditioning units are the very best thing for some situations. Of course they can be installed in the place of most any central air conditioning unit. They also are a very good alternative to window air conditioning units. I will explore the use of these units more closely and look at how they can be used effectively.
One of the many problems encountered by the professional is when they are asked to install central air conditioning in an older home that was never designed with air conditioning as even a possibility. The walls may be very thick stone. Often they have very little or no insulation. The floor structures may be rough cut lumber. The joists spacing may be random. Walls and ceilings are plaster and lathe. Basically everything is stacked against any type of ducted central air conditioning. Many log style homes also are not very easy to get any kind of ducted central air conditioning installed. The open ceilings and the bare log wall design does not allow for any kind of ducting. I'm sure there are other situations. These are the ones that I have come across most frequently.
If you have a home or building that falls into one of these categories you may want to investigate installing a ductless air conditioner. This type of air conditioner can be installed in almost any home or building. The small indoor unit can be attached to the wall with a few screws. Most of the units only require that a three inch hole be bored through the outside wall. In new installations the units can be placed on inside walls with some fore thought and planning. For installation in older homes or homes that are already built you will want to plan the units to be on the outside walls.
The outdoor condenser units can be placed up to one hundred feet away from the indoor units. One outdoor unit can be used for many indoor units. Up to four indoor units can be attached to the same outdoor condenser. Some very advanced electronics will control the operation of the condenser and compressor to supply the refrigerant to the indoor air handler units that are running at the time. With variable speed technology the compressor and the condenser fan will only run as fast as needed. This technology has become very efficient in the last few years. You do not have to give up any efficiency with these ductless split units.
Another advantage to these mini split air conditioners is that they can be controlled to run only in the rooms that you actually need air conditioning in. If you are not going to be in a room you can shut down the unit. The units also have timers that can be set to turn the air conditioning on or off at preset times. If you are not going to be home all day the air conditioning can be setback or turned off. The timer will turn on the air conditioning so that you return to a cool house. Central air conditioning is very hard to zone effectively. Also with large central air conditioning systems the outdoor compressor will be running at full capacity even though only a few rooms amy be calling for cooling. There are some central air conditioning systems that are do some staging and variable speed technology. These are not as efficient or as effective as the ductless split technology.
Ductless split heatpumps are another great idea to look at. For a few dollars more you can also very easily have heat from your air conditioning mini split. Then especially in the mild spring and fall weather you can have some very efficient heat with out starting up that big monster of a furnace or boiler in the basement. In southern climates the heatpump version of the ductless split system may provide enough heat year around.
Ductless split air conditioning is definitely something that can solve many problems for some homeowners. Add to that the many advantages of these units and you will find that they are worth every penny that you will invest into them. As with any project like this make sure that you screen your contractor. These units are not for do it yourself people. There are many things that need to be done correctly for these units to work properly and efficiently. A refrigeration license is also required to install these air conditioners.
By doing a little research and hiring the right person you will enjoy many years of trouble free service from your new ductless mini split system.

Ductless heat pump systems

Heat pumps do loose their heating capacity and efficiency as temps drop. If you decide to rely on a heat pump you may want to make sure that your system has a back up heat strip, maybe even controled with an outdoor thermostat, if that is an option. The Mitsubishi is a great product.
