What side to charge ac

The freon is added on the LOW PRESSURE SIDE ONLY. The hose tool you bought is made so you can only hook to the low side as the high side and low side fittings are different sizes and shapes for SAFETY'S SAKE.

What happens if you charge AC on high side?

The damage from trying to charge on the high side would be to you - not the system. More than likely the pressure would back up into the can and explode it like a grenade. If you don't know what you're doing, seriously get someone to help out. You ALWAYS want to connect to the low side.

Which side is the suction side on AC?

LOW SIDE - That portion of system from orifice in expansion valve through evaporator line or lines through compressor service valve to compressor reed valve. Also called suction side.

Which side is low pressure side of AC?

There's two lines coming out of the back of the compressor. You have a skinny line. And you have a

Which line do you add refrigerant?

Many of us have been taught when adding refrigerant to a system, this should be done by adding vapor refrigerant into the suction line. Vapor is recommended to insure one does not flood the compressor with liquid and potentially damaging the compressor.

Which line do you put refrigerant in?

As we add refrigerant what's going to happen as we put the refrigerant into the low side.

Which side is high pressure side of AC?

Your refrigerant travels along the high side of your system after leaving the compressor and before arriving at the evaporator coils. On the high side, the refrigerant is a hot, high-pressure gas.

How do I know which way the air flows in my AC?

The arrow on your filter should always face the unit and away from the return air duct that carries the air that will be heated or cooled. HVAC systems push the cool or warm air out and pull spent air in, recirculating the air throughout your home.

Which AC line is the suction?

The larger line typically carries a cool gas and is insulated. This is commonly referred to as the suction line, but it is also called the return line or vapor line. The smaller uninsulated line typically carries a warm liquid. It is most often called the liquid line.

What is high side and low side in AC?

High side and low side refer to the pressures in the two halves of the system. AC works by compressing refrigerant in the compressor (the beginning of the 'high side'), cooling in the condensor it, and then expanding it to absorb heat (where it enters the low side).

What color is the high side on AC?

Manufacturers color-code the hoses to distinguish between high pressure and low pressure. Low-side hoses are blue while the high side is red. The blue hose reading ranges from 0 to 99.9 psi while the red hose goes up to 999 psi.

What should the high and low side pressures be?

The pressure reading from the low side should be between 25 and 30 psi and the high side between 200 and 250 psi. But if you see the AC low side high, high side low, such as the low side is 100 and the high side is 150, there might be problems with any of the inner components.

Which line goes from compressor to condenser?

The suction line connects the evaporator to the compressor, the discharge line connects the compressor to the condenser, and the liquid line connects the condenser to the expansion device. The expansion device is typically located at the end of the liquid line, at the inlet to the evaporator.

Is the liquid line the high side?

at this point it is the hottest (high pressure). It then enters the condenser where it begins to give off heat to the outside and turn into a liquid. When it exits the condenser, it is in liquid form and is still warm (liquid line), and still under high pressure (high side).

What happens if there is air in the refrigerant line?

Air will cause a reduction of condensing surface area and cause high condensing (head) pressures. Air can enter the system through a leak in the low side of the refrigeration system. Refrigerant leaks will eventually lead to an undercharged system. Severely undercharged systems will run vacuums in the low side.

Which line is the low pressure AC port?

And one with a lower diameter the look the smaller diameter is the high side tube. The wider

Should refrigerant lines be cold?

The Copper Pipe (Suction Line) should be sweating and cold to the touch during a hot day. If it is not cold, your compressor could be off (bad capacitor/ hard start kit) or low on Refrigerant.

How do I know if my AC is low on refrigerant?

7 Signs Your AC Unit is Low on Refrigerant

It takes a long time for your home to cool off.
Vents are not blowing cool air. ...
The temperature you set is never reached. ...
Your electric bill is higher than normal. ...
Ice on refrigerant lines. ...
Water leaking around heater. ...
Hissing or bubbling noise.

Why is AC low side high?

AC low side pressure getting too high means that the system can't generate the needed temperature to cool down the vehicle. This situation could be related to several possibilities. It could be something to do with the compressor or refrigerant added to charge the AC or even a leak in the system.

Which AC line is cold?

Identify the correct AC line to insulate. A typical residential AC unit has two copper lines that both exit the building exterior and run to the outside condenser unit. Only one of these copper pipes, the cold line, should be insulated. This is called the “suction” pipe and is typically the larger of the two pipes.
