Always to the low pressure side. The low pressure side fitting is normally near the dryer ( large silver canister).

Charged on the low side service port. If you connect a small can of Freon to the high side with the system on, the can may explode from the high pressure introduced into it.....

What side do you put freon in on out unit high or low side?

Freon goes into the low pressure side of the air conditioning system. The attachment from the gauge used to put the freon in will only attach to the low pressure valve so it would be pretty hard to do it incorrectly.

Which side does the freon go into the high or low pressure end?

R134a goes into the low pressure port

Connect a freon gauge and can to the low side AC port. Start the car and turn the AC on high. Open the freon valve and fill the system to full on the gauge reading.

How do you tell difference from Low Port and High Port on home AC?

high side goes to condenser fan coil on roof low side is the evaporator si de the coil thathas a blower to blow cold air in your house on your init it should have l or hby vavles WATCH OUT high side has very high pressure when chargeing adding freon do it with low side can of freon is marked gas or liqued try to charge by gas liqued can be done but without experience you could hurt you unit

Is the ac line under pressure and if so how do you relieve it to replace the compressor?

Yes the ac lines are under pressure. The high side is under dangerously high pressure. The Freon needs to be removed by a reclaiming machine and the pressure will be removed.

How do you re gas your air conditioning on your ford focus?

You recharge an A/C system by adding freon through the Low side port. Look for the L on the cap. Never recharge on the high side. Too much pressure on this side and your freon can might explode. OK, once again it's not freon! it's R134a refrigerant that should be used to fill your car system. Many people call it freon but you need the r134a refrigerant( and oil, too). Anyway, freon cans are only available to certified mechanics in most states now.

How much freon pressure for a car?

It depends on the outside temperature but the average low side pressure should be around 35 to 40 psi and the high side should be no higher than 250 psi..........

How do you charge the ac in a 2001 Buick le Sabre?

Freon is added through the low side ac port. A gauge is recommended to check the Freon pressure, as too low or too high pressure can cause the ac not to work properly.

How often to add freon to ac unit?

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

Your air conditioner wont take any freon high side and low side dont seem to have any freon in the system you dont hear the compressor kicking in either whats wrong?

Take this to a professional. You have neither the tools nor the expertise to repair. If you tried to add freon to the high side, you've already cheated death once. That side has more pressure than the refill can and it may flow from the system into the can and cause it to explode.

What kind of freon does your 99 ford windstar use and where is the low and high side?


Where is the low pressure valve located on a 1998 Pontiac Transport?

If you are talking about the low pressure side recharge valve for the A/C system it is sort of low along side of the engine next to the radiator. It will be a fitting attached to a steel line that has a plastic cap on it that must be removed in order to put freon into the A/C system. It is called the low pressure side because it means it is on the suction side of the A/C compreesor (there fore low pressure) you never add freon to the high pressure (discharge side) of the system. This recharging is supposed to be done by service people with the correct knowledge and the equipment to prevent leakage of freon( one of the ozon depleating gases) to the atmosphere.

What is causing your 5 month old Air Conditioner to lose freon each month?

You have a leak; most likely in the high pressure side of the system.

2002 beetle shows high side port in front near radiator and low side in front of passenger firewall however my pressure gauge for freon fits high side valve and shouldn't it fit low side?

The port next to the radiator is the low-side port

What does high-side and low-side mean with respect to car AC's?

High side and low side refer to the pressure in the ac system. Ie The high side is the high pressure line and low side is the low pressure line.

Where do you add freon to your 1999 Honda Accord air conditioner compressor?

You don't add Freon as it has R134a not Freon. You add it to the low pressure side which is the larger hose.

How do you get a 1986 Volvo to take freon?

Everyone will tell you it's better to take your car to the shop to have AC work done. It can be dangerous and illegal to vent the freon into the atmosphere. But first of all, we need to know if the AC has been converted to R134A? If it's R12 you're going to have to convert it to the readily available R134A. If it is already R134A and by "to take freon" you mean add freon, then you add it to the low pressure side port. It's said that the hose that connects the can to your AC system won't connect to the high pressure side, but do not even attempt to do this. Thus the dangerous part earlier. I have heard it can explode. The low pressure side fitting is usually under a blue cap. And the high side is under the red one. Also do not overfill. This can be dangerous as well. If you have added a can and it's still not getting cold inside do not continue to add any more. Something is probably broke and adding more freon won't help it. But once again it is recommended to take it to the shop.

How do you add freon to a 1991 Acura Integra LS?

Same as any other car...attach fill hose fitting to the low pressure side of the system (it won't fit on the high pressure side fitting) and open the fill valve.

Where do you add freon to a 1995 Ford Escort?

There is a schrader valve on the low pressure line (larger a/c line). That's where you hook up the hose. Be sure to hook it up to the LOW PRESSURE SIDE, because if you hook it up to the high pressure side the can could EXPLODE.

Can't locate port on 1997 cavalier to recharge air conditioning any ideas?

find the low pressure side, usually adjacent to the firewall, or the line before you reach the compressor. You can get a can of freon with the pressure gauge already attached at any of the chain car parts store. If you accidentally connect to the high pressure side it will give you a high reading so you know not to try to fill that side with freon. It can cause the can to burst so be careful.

Before you add freon to the ac do you need to check the pressure of the high and low side at the same time or one by one?

You will be checking the pressures at the same time......

Which side does freon go in on a1999 Toyota Corolla?

It uses R 134 not Freon (R12) and it goes in the low pressure (return) side, the only fitting the new 'kit' to recharge will accept. You can't put it on the high pressure line the fitting is different, years ago when the fittings were the same people were blowing themselves up pumping the referigerant IN to the can

How do you add freon on a 1990 240sx?

Freon is added to a 1990 240sx by connecting a Freon source to the low pressure side of the system and allowing it to pull in Freon. This is done with the vehicle running and the air conditioner blowing.
