Suncutter A/C needs freon. I have added freon to my vehicle system myself. Are home units set up the same way as automobile systems?

To a point yes they are. But home units require a different type of freon, the oils are different and you can cause major damage using the wrong freon or using the same gauges that where used to fill a car, also the residential or commercial units use a very specific amount of freon and if you are to high or to low you can cause damage. You should not be low on freon and it is recommended that you get a qualified service technician out to look at your unit and run dye through it to find the leak. If this is a newer system you are running very high PSI throughout your system and without the proper equipment you can cause damage to yourself or the unit. I hope that this kind of answers your question

No, completly different. you need the proper tools and they are not cheap. also i think the smallest tank of freon (usually R22) you can get is 30LBS and you have to be certified to buy it.

Where is the freon line ford 202 ford tauras

Automobile A/C system repairs are regulated by the government due to the interaction of FREON with the atmosphere.
Being as you are clearly unfamiliar with the system I would advise that you consolt a local garage to do any A/C work on your vehicle.

That being said ;
There are TWO sets of Freon lines.
One set being the HIGH side which feeds the freon to the compressor .
The other being the LOW side .
The A/C coolent lines are a closed system and located in the front of the radiator in the form of a Condensor.
The Compressor is mounted on the engine and has lines going to and from it .
The FREON LINES are rather large aluminum hoses that have , at intervals, flexable rubber lines in thier circuit.

On a 2002 you will note the bright green Valve caps on the shreader valves located the left (passenger side) in the under hood (engine compartment).

My air conditioner works but does not cool . i have added freon the last two years and fixed the problem ,did the same thing this year but did not help .

When self adding freon after it leaks out you get air trapped in the system. After adding freon a couple of times the air expands not leaving room for the needed freon. To continue adding freon with air tapped will knock the compressor out pretty quickly, there's not enough room for both & the air is keeping the freon from being able to cool properly give the false indication of being low on freon. The freon you are adding has the dye added to assist in finding the leak since freon does not evaporate nor dissipate it its being leaked out. A black light will assist locating the leak. The best thing is to have the unit checked & serviced by a mechanic...he'll charge about $ 150.00 to check for leaks, remove the old freon...his machine will tell him how much air its trapped in the system by how little freon is removed. For the service fee he will replace valves & gaskets, where needed, correcting most leaks. After sucking the system down & recharging the problem should be corrected.

How do I add freon to my ac compressor?

unless you are licensed to handle freon don't. there are some big fines for releasing freon. also if you are not experienced there are safety concerns!!! Is this a home hvac or car? Now with that said you have to add it on the suction side of the compressor.You will need to know the correct type of freon that goes in your unit which can be found on a tag on the unit. You will also need a set of ref. gages to monitor the low and high pressure sides of the unit. it also needs to be added to the outside unit service ports (Home). You need a set of ref scales so you know how much ref is being added. Too much ref and you start pumping liquid. Too little ref and it doesn't cool like it should. If its a car you still need the above equipment. still goes in the suction side.If you add to much ref you can lift the safety pressure valve and dump the freon in the car system. Each type of ref has a pressure you want to see on the suction side and hp side. since they differ with each type ref. you will have to look it up possibly on the internet. If suction pressure goes below 32 degrees you may freeze any condensate the unit makes and have another problem. Hope this helps you but its not as simple as hooking up a ref cylinder and just adding freon. their are many thing that can go wrong and damage equipment or hurt is the first priority.

Added freeon an air still doses not get cold i was told it could be the air conpeessure.i need to know how to check it and how to repair it

Dependeing on how old the car is, You may just need to have a vacuum pulled on the system in order to be able to add the proper amount of freon. The vacuum allows for you vehicle A/C system to take in more freon. As the vehicles get older, the seals tend to shrink and cause most systems to lose freon and the vacuum.

Where do i ad freon to my chevy equinox

You shouldn't ever have to add freon to an a/c system. It is a closed system - like your refrigerator. When was the last time you added freon to your refrigerator or home a/c when there wasn't a problem?

If you are needing to add freon, then you have a leak somewhere that needs to be repaired. Your local automotive technician can diagnose the problem for you. Freon should only be added by trained professionals. If you don't know what you are doing, you can charge the system incorrectly causing significant damage to the system.

If you still want to do it yourself, reference this article.
You will need a set of A/C Gauges, and freon.
Do NOT put any type of stop leak into the system - this can cause irreversible damage to the compressor.

Adding freon to my home air unit my air is 4 yrs old am tired paying this company every summer to add freon and it keeps flooding my house never gets cooler than 80 they come out at least three times a...

Why would you be paying for refrigerant on a 4 year old system when most systems have a 5 year warranty on sealed systems.
Sounds like who ever it is servicing is ripping you off.

Ice is forming on coil fins

Either your coil is dirty or filter is dirty. Worst case your low on freon which would make a coil freeze.But freon doesn't evaporate if your low there must be a slow leak.

A/C Problem

in order to do this job properly you need special recovery equipment to recover the freon and after the job you need to have a vacuum pump put on the system to get all the air out and check for leaks prior to charging
what you can do is have a shop recover the freon then go home and do the work your self then go back to the shop and have them pull a vacuum on it then charge it

you can charge the system your self but if you dont pull a vacuum it will never blow very cold

is it the evaporator leaking or the expansion valve leaking or both?

get your self a good repair manual and it will walk you through either of these jobs

This is a typical symptom of having an A/C system low on freon if it cycles on and off when first turned on or very soon afterward. All types of A/C units for home and auto have a low pressure cut-out switch that will disengage the compressor when the freon level drops low enough to cause damage to the compressor. The unit needs recharging with the proper amount of freon to correct the problem. If it's an automobile A/C system and the freon level is okay, it could be a faulty compressor clutch or coil.
