Re: regassing of fujitsu splitsystem airconditioner
All split ac can be regassed, but if it was only installed recently and the gas has leaked out then it will either be a manfactures warranty job, or if it was poorly installed it should fall under the warranty of the installer. most cheaper installers however only give a 3-6 month warranty on thier work if they give one at all. If it is uses either R410 or R22 gas (it will say on the outdoor unit) than any liscensed and i stress liscenced installer can fix the leak and regass it.

Hi Barry, If you look carefully at the two AC pipes you will see two plastic valve covers (similar to valve caps on tyres, but larger). One is high pressure and the other low. When regassing the engine should be running ith the AC turned on. Regards John
Air conditioner compressors take up to 5 hp to run that is why when to unit cuts in the engfine revs drop until the computer compensates for the rev drop Can be as much as 700 rpm. conversly when the compressor disengages the engine will over rev until the computer compensates. If you didn't have a problem before but do now it is possible that too much gas was put in the a/c system meaning the compressor is almost locking uo. Have the system pressure rechecked
you will need to get it regassed or checked atleast, the aircon will not kick in or engage if the gas pressure is low or empty, have them run a dye through the system aswell incase it leaks they can track the leak and fix it for you.
has it got aircon gas? the system wont work without the gas, the compressor wont even engage if its not pressurised. you may need to go to an aircon regasser and have them run the dye through it to check for leaks, once its regassed the compressor should engage. if the system then goes warm within the next week you have a leak and they will track it with a black light searching for the dye they fill it with.
If freon was added because of a leak, it could have leaked down again. If freon levels are too low, the compressor will not switch on. Check to see if the center (it is connected to the compressor shaft) of the compressor pulley is turning.
An air con unit of any make should never need to be regassed if initially installed correctly. If it needs regassing, there must be a leak. You would have to find the leak and repair it before regassing, or it would be the same as pumping a tyre with a slow puncture. Generally most simplex systems use around 750 to 800grams.
