Ductless Split System

The mini split systems come preloaded with freon. This allows everything to install the device, and connecting lines. It indicates to serve or to evacuate the system after the lines are connected. air would be effective from the 15 "lines were connected. long will the good AC without being purged or evacuated? ductless system that is new, and I've heard people install them without fancy equipment. id like to know if I can get a good cooling without the tools of CVC. What do you think?

Mini-splits are expensive. You take a big risk here, and it can not work for you. simple molecules of water and dirt can cause big problems with the compressor and metering device for the refrigerant. Why not find someone in the trade, and offer them some money to remove lines and connect your equipment professional? If something goes wrong, and the lines were not evacuated, you may be hard to get the manufacturer honor a claim. Better safe than sorry!

If the device is not installed by a professional manufacturer will probably not guarantee a portion of it.

Sure, you could get a good cooling, but you will not get more than you can. You diminish the effectiveness of the device. You shorten the life of the unit.

If the manual says to bleed, you must purge with refrigerant that is in the system. Can I purchase refrigerant? You should not have been sold the product.

Since you have the unit, you can do what you want.

The manufacturer I work for does not guarantee mini split installed by customers.

Good luck ... you'll need.

The problem could be inside air handling, he probably air in and also the humidity.

It will work! I do not recommend trying. If you do not flush the lines, you risk contaminating your system. This means that if you do not mind burning your compressor, and having to buy a new one, because you void your warranty then go for it. I should also mention burnout will result in more money to clean the system you already contaminated.

My advice is if you do not want to do everything you do not, but you must understand the risks that I detailed for you!

Good luck! It should only take an hour for an HVAC guy to pull a vacuum on the system.
