Can AC hoses be repaired?

Although the AC, or air conditioning, lines in most cars today are aluminum, there are still plenty of older cars out there that use rubber hoses for their AC systems. Rubber hoses are flexible and versatile, and are fairly easy to repair, but the rubber decays over time.

What happens if you put too much refrigerant in your car?

As a common side effect, excess freon gas can prevent the compressor from working at its capacity. In some cases, extra freon accumulates inside the compressor and results in subcooling or undercooling. In the worst of cases, the freon gas may even damage the internal mechanism of the compressor.

What happens if you add too much R134a?

The problems with too much refrigerant

A refrigerant overcharge alters the pressure inside the air conditioner and puts the compressor in danger. The Compressor: Excess refrigerant creates a danger called slugging. This is when extra refrigerant floods into the piston cylinders of the compressor when in a liquid state.

Do you add refrigerant to the high or low side?

For systems under a vacuum, once the desired vacuum level has been reached, the vacuum pump has been isolated from the system, and no leaks exist, always charge liquid refrigerant in the high side of the system until high- and low-side pressures equalize and liquid stops flowing.

Can I use R134a in my home AC?

While used mostly in cars, only one home air conditioner has been made, as of November 2010, that uses R134a as a standard. As of 2010, new home air conditioners that are produced must use a refrigerant that does not deplete the ozone. R134a is a hydrofluorocarbon that does not cause environmental harm.

Can you mix R134a with R1234yf?

If you were to put R1234yf in a system designed for R134a, it looks like you’d end up with about a 10% loss of cooling capacity, but putting R134a into a R1234yf system would be a wash. It appears R1234yf oil is compatible with R134a (but not vice-versa), so shouldn’t be a problem there.

What is the difference between R22 and R134a?

R22 refrigerant belongs to a class of chemicals called hydrochlorofluorocarbons that have been phased out for new air conditioning and refrigeration equipment because of their ozone-depleting effects. R134a refrigerant is an alternative that contains no chlorine and hence no ozone depletion potential.

Do I need to add oil when recharging AC?

Which AC Components Require an Oil Refill? The compressor is the part of the AC unit, It needs enough oil to run smoothly. Typically, there is no need to add oil to the current AC system of your car unless you have modified the compressor or a leak happens, causing the system to drip oil.

Can you pull a vacuum on just the low side?
