BEST PRICE MINI SPLITS - Hitachi/EcoBreeze 866-474-5061.

How a mini-split air conditioner/heat pump works:
A mini-split air conditioner works the same way that your central air conditioner system works. The brains of the unit is the outside compressor which is a Japanese Hitachi compressor.

The only thing that is ECO-BREEZE about this unit is the inside evaporator which is just a fan blowing room air across the cold coils. This means that this unit is 90% Hitachi with a ECO-BREEZE fan inside.
Lets talk about how a mini-split air conditioner/heat pump works. The outside condenser (made by Hitachi) condenses the Freon into a very thin line inside a copper tube, and that is all the outside condenser does is to condense the Freon into a liquid.

As the Freon leaves the outside Compressor it enters a big half inch diameter copper tube and the Freon changes from a liquid to a gas and gets extremely cold. The cold half inch line, wrapped in insulation, then travels through this copper line from the outside compressor up the side of the wall through a 3.5 inch hole to the inside evaporator unit with the fan. So you need to drill this 3.5 inch hole all the way though the wall.
The inside evaporator unit mounts on a wall onto a thin metal bracket over the 3.5 inch hole so you cannot see the hole from the inside. The evaporator is mounted 4 inches from the ceiling. It is mounted out of your normal line of sight, you really do not notice it unlike a window unit that mounts in the middle of the wall. The biggest inside evaporator unit sticks out from the wall approximately 10 inches, and is 13 inches high and 4 feet wide. Again, you don't really notice it because it is mounted up by the ceiling.

The half inch Freon line enters the inside evaporator where it breaks up into thin copper lines that run across the length of the inside unit. Room air then enters the unit from the top of the inside unit and blows across the thin, cold metal tubes chilling the air which then blows out the bottom front of the unit into the room. There is typically a 19 degree Fahrenheit temperature drop from the air entering the top of the inside unit to the air coming out at the bottom front of the inside unit. Horizontal louvers at the bottom front then fan the air vertically across the room.

The Freon then leaves the inside Evaporator unit via a quarter inch copper line, back through the same 3.5 inch hole back to the outside unit to be re-condensed again and the cycle repeats. The outside compressor then blows hot air outside.
For electricity, a 110volt or 220 volt line is ran from your electrical panel to a quick disconnect box next to the outside compressor. The compressor is then hardwired to that outside quick disconnect box to get its electricity. The inside unit gets its electricity from the outside unit from a wiring harness that runs from the outside to the inside unit through that same 3.5 inch hole. Usually wiring harnesses from the inside and outside units just clip together.

As air passes over the inside evaporator unit's cold copper tubes, the moisture in the air condenses and drips. A collecting device then channels the water back out through though the same 3.5 inch hole to the outside. So obviously as it cools, it is removing moisture from the air acting as a dehumidifier.

Outside, it is best to place a 4 inch wide vertical metal cover over the copper tubes, wire harness, and drain line to make it look better. The cover would run from the 3.5 inch hole down to the ground where your outside condenser unit is.

The outside condenser unit can either be mounted onto a concrete pad or pressure treated logs on the ground, or a L-Bracket mounted on the side of the building or mounted on the roof.

Can an individual install these? We recommend you get a licensed installer by posting a job on www.Craigslist.com which is usually free or $25 in some major metro areas. State in your ad, that you want to see their license and that they have to have prior experience installing mini-split air conditioners although it is not necessary. We do have many individuals install these themselves and the worst thing that I hear is they lost their Freon and now have to call a licensed installer to finish the job because only licensed installers can buy Freon. Normally you can get someone to run the electrical and install the unit for $500 if you post the job on Craigslist. Compare this to the normal retail price have an electrical contractor install one for $3000 to $4000. You can save more than 50% If you buy the unit from us for $700-$1000 and add the $500 installation for a $1200 to $1700 total.

The installers might charge you $30/pound for the R410A Freon but it only costs them about $6/pound. Expect some markup though. The compressor comes precharged with plenty of R410A Freon for both the lines and the unit without adding extra Freon if using about 15 feet of line.

When dirty, the filter can be rinsed with water and reinstalled.
This unit works as a great heater also. All it does to heat is to reverse the direction of the Freon. During air conditioning mode, cold air is blown inside and hot air is blown outside. During heat mode, heated air is blown inside and cold air is blown outside.

Some of the controls on the remote control are power on/off, Set temperature +/-, fan speed, louver on/off, and a mode button to change from air conditioning to heat to fan only.

Normally most name-brand air conditioners come with a 1-year warranty. One internet seller is advertising a longer warranty but every 6 months, he shuts down his website and starts a new one. Beware of this.

Basically all minisplits are made by 5 different assembly factories that purchase their parts from the same two suppliers plus the Japanese name branded compressor. This is why all minisplits look the same with different face plates only. What we do is to sell you this same unit cheaper than anyone else because of our lower overhead. We sell the minisplit units direct to the public cheaper than the installers can buy them at wholesale prices.

The units are shipped by common carrier to your doorstep. We usually use Saia, UPS Freight or Fed-Ex Freight to ship you your unit. Most of the major metro area can receive our units in 1 to 3 business days from our Dallas, Texas warehouse. For rural areas it could take an additional 1 to 3 days.

The advantage of a minisplit systems over a window unit is the window unit is much louder because the compressor is not outside but inside the window unit. The window AC unit also mounts in a window which is usually in the middle of the wall creating and eye sore. Window units are also 10 Seer and Mini-split units are 13 Seer, so the minisplits use 30% less electricity than the window units. Minisplit/Heat Pump units also heat as well as cool. To change you simply push the mode button on the remote.

Usually Minisplit systems are added when converting garages because you cannot take ducting from the house's central air system or the house will be too hot. Also the converted garage is going to be a bedroom, family room or game room, and a window unit is so loud that you cannot enjoy yourself. Also you have to cut a huge hole in the wall for a window unit and only a 3.5 inch diameter hold for the minisplit.

The minisplits are also used in Cabanas, bath houses, added dens or to old houses that have no room for the ductwork that is required for central air units. Solution is to again use a minisplit AC system for the best low-priced fuel efficient alternative. Some houses have central air systems that will not cool the house down to the desired 72F when it is 105F outside. The best solution is to add a 24,000 BTU to give you additional cooling power and only turn it on when you need it.

Usually the outside compressor and inside evaporator are obviously then mounted on opposite sides of the wall very close to one another.

The high seer minisplit units such as 20-seer use inverter technology to use even less electricity than the standard 30-Seer units. The 20-Seer units are also more expensive though. It might take a few years before your energy savings exceed the extra price that you paid for the unit though.

Multiroom units can come as 2-1 or 3-1 are very expensive. It is cheaper to buy 2 full units then it is to buy one two room unit.

Buy EcoBreeze and get Hitachi quality, save 50% to 70% on the cost of the unit and installation and 30% on your air conditioning bill.
