Want this question answered?
not dure if this will help but when i charge a unit either low or complete charge,the jug is weighed before the charge and after to see the weight of freon
Service call freon check it out for clogged condenser $100.00
Probably close to or more than a new unit would cost.
Fittings for 134 freon
where is low side charge port located
The amount of refrigerant a unit contains depends on the size of the unit. That is the standard charge but the charge after the system is installed may be more or less. The system charge depends on the size of the refrigerant lines, the length of the lines, and the size of the unit.
It varies per contractor. They usually charge for their labor and disposal fee.
your freon is measured with gauges hooked up to low side of air condition unit the low side is the cold side high side is the condenser side WATCHOUT high pressure every unit has atag on it and let you know how many ounces to be put in low charge is bad but over charge is also bad
By buying an AC charge hose and a can or 2 of R134a freon (depending on how much your car needs) Attach hose to the low pressure side & charge system. Do not overcharge, or you may destroy the AC system.
Yes, depending on how long the lines are. The unit should have a sticker showing the unit's charge, then you have to figure the lines and the coils in the furnace.
It does not contain any Freon (R-12). R134A is the proper refrigerant. My advice to you is to let a professional do the work. By reading the question you are not qualified to charge the unit, because you dont know where to put your gauges on the system.
overcharging a central air unit system with refrigerant(freon) will cause the head pressure to be?
