Hello i want to refill my home A/C r407c freon type and i need some guidance. can you help me pls?

Have a heating/air conditioning person check the freon level to see if it needs to be refilled. Most modern day things that cool use freon gas to cool. It could be that it needs to be flushed and refilled, or perhaps you have a leak somewhere and all the freon is leaking out or has leaked out. Trust me one of my uncle's is a heating and cooling technician at a company called WinAir and he has fixed our home cooling systems many times. Those guys have tools, freon, and the right chemicals to see if you have a leak and need more freon.

There is seldom a means by which the refrigerant can be isolated in this type of system. Moveover, since the system has had a leak, the refrigerant in the system is no longer usable. It is made of HFC-125, HFC-32 and HFC-134a in specific proportions. When a leak occurs, these components will leak at separate rates and the remaining refrigerant (if any is left) is no longer capable of doing the work of a virgin refrigerant.

Refrigeration flare fittings are 45° and are made with special tools. While there are 'washers' that can be inserted into the fitting when it's exposed, they are not that effective all the time. Remember that the pressure at the condenser part of the system can well exceed 300 psig.

The refrigerant, Genetron 407C, is the replacement for HFC-22. It has no 'replacement' per se.

It's my opinion that this is an issue for a reputable HVAC technician, and not a homeowner. To do the job properly, you would need a new filter/drier, flaring tool and torch if the line is not long enough for it to be re-flared and reconnected, vacuum pump and virgin refrigerant. I would bet that the location of the leak is such that the system is all but flat at this time, and you need a precisely measured amount of refrigerant to re-charge the system.

If you've not yet done so, TURN THE SYSTEM OFF to protect the compressor from damage.

Hello
If its not cooling good you may have lost some freon due to a leak.You will need to have the unit leaked checked and refilled.

If you do not feel or hear the fans running then you may have a bad fan motor,which will need to be replaced.

Hi,
No.... they are totally different gases and if you mix them you are really in trouble.... only use the specified gas and NEVER mix gases!!

If you are not trained to at least charge a unit U will in the end do more harm than good get the proper service. what makes U think U need freon could just be dirty? Tom

Call someone who is "Certified"

First of all this car does not use Freon. It uses R-134a refrigerant.

Recharge through the a/c low side port, on the passenger side just in front of the firewall.

I have heard that there is a spray you can use that will not damage your system and seals the leak when it comes in contact with oxygen
