You need to look at the manufacturers plate on the side of the compressor as to the type of freon needed. It will tell you type and amount (in ounces) that is needed. You can buy 134 over the counter at any auto parts house without a license however, you need a license for the purchase of r-22

I have a Mitsubishi MS-XV07UV air con. unit - Have asked a local company for a price to check gas levels and re gas if required - as it uses R22 refrigerant he says it cannot be done is this correct ?

No. The pressure can be checked, regardless of the refrigerant type. But, if it needed to be recharged, the existing R22 Freon Gas would have to be evacuated and properly disposed of and the new, approved type R134a. would have to be installed.

Try contacting another service company and see if you get the same answer as the first.

This is a 3 1/2 Ton unit that is low on R22 but still does cool enough to freeze up. The A/C tech insists that it needs over 4lbs of freon, does this seem right to you?

Hello TF YES to make ice on low freon you lost more than 1/2 of the factory/system charge.4 lbs is about rite.I would like to find the freon leak as you will always have to replace the gas every now & again untill found & repaired.

Roof air not cooling, what is the correct freon to add r22?

On the outside of the unit on the cover,there is a nameplate rating that should tell you how much and what type of freon is in it.

Mr slim Mitsubishi - how much fill

On the data plate for the outdoor unit it will tell you what type and how much refrigerant you need. If the line set is longer than 25 feet you will likely need a bit more than what it says. A 40 degrees evaporator temperature is ideal, approximately 65 psi for r22

I have a 30 year old Kenmore 17 cu in. refrigerator that recently has started to run almost continuously. It is otherwise in good shape. Room temp. is 68 deg. farenheit, 70% rel. humidity. I have an R-22...

this unit does not take r22. dont put r22 in it , thats for house acs.this unit should take r12 older freon . but id first check the condenser coils, if this unit has any, some models are internal. usually underneath unit or against back wall. if dirty coils that will make ref. run longer. if coils are clean and cooling or frzing in both sides then maybe your thermostat is not sensing the tempreture properly, maybe hard to get part becuz of age. if unit is frzing and cooling good just running too long, i dont think its low on freon,if its low on freon it wouldnt be working at all . hope this helps

How do you add coolant to a goldstar air conditioner

There are two lines leading into the unit, the high side aND THE LOW SIDE. tO ADD FREON you need to add a valve to the low side line. But if you have a leak that indicates that moisture is in the unit and you need to pull a valum to remove the moisture before ADDING ANY FREON. There are as last known three types of freon, R22, R134a and this last one I dont even know the name.

Dometic Quick Cool compressor freezing and evaporator coil

Could be low. First check air filter, air flow, and evap coil to see if it has restricted airflow. If all seems well, its probably low. The specs will tell you what type and how much refigerant. To access system, you will need a gauge/manifold set, refrigerant, and a piercing or line tap valve for the low pressure side of the system. Of course, first, you need to locate and repair the refrigerant leak.

No, R12 and R22 are not compatible freons. You need to recharge with R22.
